Large marine mammals of the order CETACEA. In the past, they were commercially valued for whale oil, for their flesh as human food and in ANIMAL FEED and FERTILIZERS, and for baleen. Today, there is a moratorium on most commercial whaling, as all species are either listed as endangered or threatened.

Structural dynamics of ligand diffusion in the protein matrix: A study on a new myoglobin mutant Y(B10) Q(E7) R(E10). (1/602)

A triple mutant of sperm whale myoglobin (Mb) [Leu(B10) --> Tyr, His(E7) --> Gln, and Thr(E10) --> Arg, called Mb-YQR], investigated by stopped-flow, laser photolysis, crystallography, and molecular dynamics (MD) simulations, proved to be quite unusual. Rebinding of photodissociated NO, O2, and CO from within the protein (in a "geminate" mode) allows us to reach general conclusions about dynamics and cavities in proteins. The 3D structure of oxy Mb-YQR shows that bound O2 makes two H-bonds with Tyr(B10)29 and Gln(E7)64; on deoxygenation, these two residues move toward the space occupied by O2. The bimolecular rate constant for NO binding is the same as for wild-type, but those for CO and O2 binding are reduced 10-fold. While there is no geminate recombination with O2 and CO, geminate rebinding of NO displays an unusually large and very slow component, which is pretty much abolished in the presence of xenon. These results and MD simulations suggest that the ligand migrates in the protein matrix to a major "secondary site," located beneath Tyr(B10)29 and accessible via the motion of Ile(G8)107; this site is different from the "primary site" identified by others who investigated the photolyzed state of wild-type Mb by crystallography. Our hypothesis may rationalize the O2 binding properties of Mb-YQR, and more generally to propose a mechanism of control of ligand binding and dissociation in hemeproteins based on the dynamics of side chains that may (or may not) allow access to and direct temporary sequestration of the dissociated ligand in a docking site within the protein. This interpretation suggests that very fast (picosecond) fluctuations of amino acid side chains may play a crucial role in controlling O2 delivery to tissue at a rate compatible with physiology.  (+info)

Declining survival probability threatens the North Atlantic right whale. (2/602)

The North Atlantic northern right whale (Eubalaena glacialis) is considered the most endangered large whale species. Its population has recovered only slowly since the cessation of commercial whaling and numbers about 300 individuals. We applied mark-recapture statistics to a catalog of photographically identified individuals to obtain the first statistically rigorous estimates of survival probability for this population. Crude survival decreased from about 0.99 per year in 1980 to about 0.94 in 1994. We combined this survival trend with a reported decrease in reproductive rate into a branching process model to compute population growth rate and extinction probability. Population growth rate declined from about 1. 053 in 1980 to about 0.976 in 1994. Under current conditions the population is doomed to extinction; an upper bound on the expected time to extinction is 191 years. The most effective way to improve the prospects of the population is to reduce mortality. The right whale is at risk from entanglement in fishing gear and from collisions with ships. Reducing this human-caused mortality is essential to the viability of this population.  (+info)

Sex-biased dispersal in sperm whales: contrasting mitochondrial and nuclear genetic structure of global populations. (3/602)

The social organization of most mammals is characterized by female philopatry and male dispersal. Such sex-biased dispersal can cause the genetic structure of populations to differ between the maternally inherited mitochondrial DNA (mtDNA) and the bi-parental nuclear genome. Here we report on the global genetic structure of oceanic populations of the sperm whale, one of the most widely distributed mammalian species. Groups of females and juveniles are mainly found at low latitudes, while males reach polar waters, returning to tropical and subtropical waters to breed. In comparisons between oceans, we did not find significant heterogeneity in allele frequencies of microsatellite loci (exact test; p = 0.23). Estimates of GST = 0.001 and RST = 0.005 also indicated negligible if any nuclear DNA differentiation. We have previously reported significant differentiation between oceans in mtDNA sequences. These contrasting patterns suggest that interoceanic movements have been more prevalent among males than among females, consistent with observations of females being the philopatric sex and having a more limited latitudinal distribution than males. Consequently, the typical mammalian dispersal pattern may have operated on a global scale in sperm whales.  (+info)

Quench-flow experiments combined with mass spectrometry show apomyoglobin folds through and obligatory intermediate. (4/602)

Folding of apomyoglobin is characterized by formation of a compact intermediate that contains substantial helicity. To determine whether this intermediate is obligatory or whether the protein can fold directly into the native state via an alternate parallel pathway, we have combined quench-flow hydrogen-exchange pulse labeling techniques with electrospray ionization mass spectrometry. The mass spectra of apomyoglobin obtained at various refolding times suggest that apomyoglobin indeed folds through a single pathway containing an obligatory intermediate with a significant hydrogen-bonded secondary structure content.  (+info)

Purification and properties of whale thyroid-stimulating hormone III. Properties of isolated multiple components. (5/602)

Properties of the four purified components of whale thyroid-stimulating hormone (TSH) have been compared. The amino acid composition shows close similarity among these components. Their hexosamine and sialic acid contents are of the same magnitude, whereas the neutral sugar composition differs somewhat from each other. The molecular weight of whale TSH determined by sedimentation equilibrium is 29,000, and no difference in molecular weight as well as in Stokes radius as determined by gel filtration has been detected among these four components. The amino acid and carbohydrate compositions of whale TSH resemble those of TSH from other species, especially those of non-primate mammalian TSH. Whale TSH contains, unlike bovine TSH but like human TSH, 1-2 residues of sialic acid as a constituent carbohydrate.  (+info)

Abiotrophia balaenopterae sp. nov., isolated from the minke whale (Balaenoptera acutorostrata). (6/602)

Phenotypic and phylogenetic studies were performed on a hitherto undescribed micro-organism isolated from a minke whale (Balaenoptera acutorostrata). Comparative 16S rRNA gene sequencing studies demonstrated that the unknown strain constituted a new subline close to, but distinct from, Abiotrophia adiacens and Abiotrophia elegans. The unknown bacterium was readily distinguished from these two Abiotrophia species by biochemical tests and electrophoretic analysis of whole-cell proteins. On the basis of phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium be classified as Abiotrophia balaenopterae sp. nov., the type strain of which is M1975/96/1T (= CCUG 37380T).  (+info)

Immunohistological distributions of fibronectin, tenascin, type I, III and IV collagens, and laminin during tooth development and degeneration in fetuses of minke whale, Balaenoptera acutorostrata. (7/602)

The immunohistological distributions of fibronectin, tenascin, type I, III and IV collagens, and laminin were observed in the tooth buds of fetuses of minke whale, Balaenoptera acutorostrata. Distributions of extracellular matrices (ECMs) examined in this study except for tenascin were generally similar to those of terrestrial mammalian species during development of the tooth bud. Tenascin in the fetuses of minke whale showed characteristic distributions in the dental lamina and the enamel organ in the early tooth developmental stage. In the physiological degeneration stage of tooth bud development, immunoreactivity of the ECMs were very weakly and limitedly detected in the dental papilla and the surrounding mesenchyme. Immunoreactivity of tenascin and type I and III collagens were positively detected in the developing baleen plate germ which was associated with the degenerating tooth bud. These findings suggested that expressions of the ECMs were related to the formation of the tooth bud and baleen plate germ, and that the lack of the ECMs was related to the degeneration of the tooth bud in the fetal minke whale.  (+info)

A study of vibrational relaxation of B-state carbon monoxide in the heme pocket of photolyzed carboxymyoglobin. (8/602)

The vibrational energy relaxation of dissociated carbon monoxide in the heme pocket of sperm whale myoglobin has been studied using equilibrium molecular dynamics simulation and normal mode analysis methods. Molecular dynamics trajectories of solvated myoglobin were run at 300 K for both the delta- and epsilon-tautomers of the distal histidine, His64. Vibrational population relaxation times were estimated using the Landau-Teller model. For carbon monoxide (CO) in the myoglobin epsilon-tautomer, for a frequency of omega0 = 2131 cm-1 corresponding to the B1 state, T1epsilon(B1) = 640 +/- 185 ps, and for a frequency of omega0 = 2119 cm-1 corresponding to the B2 state, T1epsilon(B2) = 590 +/- 175 ps. Although the CO relaxation rates in both the epsilon- and delta-tautomers are similar in magnitude, the simulations predict that the vibrational relaxation of the CO is faster in the delta-tautomer. For CO in the myoglobin delta-tautomer, it was found that the relaxation times were identical within error for the two CO substate frequencies, T1delta(B1) = 335 +/- 115 ps and T1delta(B2) = 330 +/- 145 ps. These simulation results are in reasonable agreement with experimental results of Anfinrud and coworkers (unpublished results). Normal mode calculations were used to identify the dominant coupling between the protein and CO molecules. The calculations suggest that the residues of the myoglobin pocket, acting as a first solvation shell to the CO molecule, contribute the primary "doorway" modes in the vibrational relaxation of the oscillator.  (+info)

I believe there may be some confusion in your question. Whales are not a medical term but rather large marine mammals. They belong to the Cetacean family, which includes dolphins and porpoises. If you're asking about a medical condition or something similar that might be associated with the word "whales," I would need more information to provide an accurate response.

I'm sorry for any confusion, but the term "Humpback Whale" is not a medical term. It is a species of baleen whale. Here's a common name definition:

Humpback Whales (Megaptera novaeangliae) are a species of baleen whale known for their long pectoral fins, which can be up to one-third of their body length, and their distinctive humped back when they breach the water's surface. They are also famous for their complex and varied songs, which can be heard for miles and play a significant role in their mating rituals. Humpback Whales are found in oceans all around the world and are currently not listed as endangered, although they have been heavily impacted by whaling in the past.

I'm sorry for any confusion, but "Fin Whale" is not a medical term. It is a species of whale, and it's the second largest mammal after the blue whale. The fin whale (Balaenoptera physalus) is a fast-swimming, long-bodied whale that's variously known as the finback, razorback, or common rorqual. Fin whales are cosmopolitan and can be found in all oceans of the world. They prefer deep offshore waters and migrate to tropical and subtropical waters in the winter to breed and give birth.

If you have any medical terms that you would like me to define, please let me know!

A Minke Whale is not a medical term. It is a type of baleen whale, which is one of the two major groups of whales and dolphins, the other being the toothed whales. There are two species of minke whales: the common minke whale (Balaenoptera acutorostrata) and the Antarctic minke whale (Balaenoptera bonaerensis). They are relatively small oceanic creatures, with a robust body and a pointed head. The common minke whale is found in both hemispheres, while the Antarctic minke whale is found only in the Southern Ocean.

Minke whales are not typically associated with medical definitions or terminology, unless in the context of a medical condition affecting the species or its population, such as a disease outbreak or injury.

I'm sorry for the confusion, but "Sperm Whale" is not a medical term. It is a species of whale, scientifically known as Physeter macrocephalus. Sperm whales are the largest toothed whales and have distinctive square-shaped heads that can make up to one-third of their body length. They are named for the waxy substance called spermaceti found in their heads, which was once mistakenly thought to be sperm.

If you're looking for a medical definition or information related to human health, please provide more details so I can assist you better.

Pilot whales are not actually whales, but they are the second largest species of dolphin. There are two species: the long-finned pilot whale (Globicephala melas) and the short-finned pilot whale (Globicephala macrorhynchus). They are known for their large, bulbous heads and their social behavior, often living in groups called pods that can number in the hundreds. Pilot whales can grow up to 20 feet long and weigh up to 3,000 pounds. They primarily feed on squid and fish. Their name is believed to have come from the fact that they were historically hunted by sailors who would use them as "pilots" to guide their ships through unfamiliar waters.

'Balaenoptera' is a genus of marine mammals that includes several species of baleen whales, also known as rorquals. Some of the well-known species in this genus are:

1. Blue Whale (Balaenoptera musculus) - The blue whale is the largest animal ever known to have existed, with adults reaching lengths of up to 100 feet (30 meters) and weights of as much as 200 tons. They feed primarily on krill and are found in all oceans except the Arctic.
2. Fin Whale (Balaenoptera physalus) - The fin whale is the second-largest species of baleen whale, with adults reaching lengths of up to 85 feet (26 meters) and weights of around 74 tons. They feed on krill and small fish and are widely distributed in all oceans.
3. Sei Whale (Balaenoptera borealis) - The sei whale is a medium-sized baleen whale, with adults reaching lengths of up to 60 feet (18 meters) and weights of around 20 tons. They feed on krill and small fish and are found in cold and temperate waters worldwide.
4. Bryde's Whale (Balaenoptera brydei) - The Bryde's whale is a smaller baleen whale, with adults reaching lengths of up to 50 feet (15 meters) and weights of around 15 tons. They feed on krill and small fish and are found in tropical and warm temperate waters worldwide.

These species are characterized by their long, slender bodies, streamlined pectoral fins, and a distinctive ridge along the top of their head. Baleen whales have baleen plates instead of teeth for filter-feeding, which allows them to consume large quantities of small organisms such as krill and fish.

Cetacea is a taxonomic order that includes whales, dolphins, and porpoises. This group of marine mammals is characterized by their fully aquatic lifestyle, torpedo-shaped bodies, modified limbs that serve as flippers, and the absence of external hindlimbs. Cetaceans have streamlined bodies that minimize drag while swimming, and their tail flukes enable powerful propulsion through vertical movement in the water column.

Their respiratory system features a pair of blowholes on the top of their heads, which they use to breathe air at the surface. Cetaceans exhibit complex social behaviors, advanced communication skills, and sophisticated echolocation abilities for navigation and hunting. They primarily feed on fish and invertebrates, with some larger species preying on marine mammals.

Cetaceans have a global distribution, occupying various habitats such as open oceans, coastal areas, and rivers. Unfortunately, many cetacean populations face threats from human activities like pollution, habitat degradation, climate change, and direct hunting or bycatch in fishing gear. Conservation efforts are crucial to protect these remarkable creatures and their vital roles in marine ecosystems.

The bowhead whale (Balaena mysticetus) is a large baleen whale species that belongs to the family Balaenidae. It is also known as the Greenland right whale or Arctic right whale. The name "bowhead" comes from its distinctive bow-shaped skull, which allows the whale to break through thick sea ice in order to breathe.

Bowhead whales are the largest species of baleen whale and can grow up to 60 feet long and weigh as much as 100 tons. They have a robust, rotund body shape with a broad, tapering tail stock and large, paddle-shaped flippers. The most notable feature of bowhead whales is their enormous, complex baleen plates, which can measure up to 16 feet long in adult individuals. These baleen plates are used to filter small prey such as krill and copepods from the water column.

Bowhead whales have a circumpolar distribution in the Arctic and sub-Arctic waters of the Northern Hemisphere, where they spend their entire lives. They are known for their longevity, with some individuals living up to 200 years or more. Bowhead whales are also notable for their vocalizations, which include a variety of low-frequency sounds such as moans, hums, and pulses that can be heard for miles underwater.

Historically, bowhead whales were heavily hunted by commercial whalers due to their large size, slow movement, and high blubber content. As a result, the global population of bowhead whales was significantly reduced, with some estimates suggesting that there were once over 30,000 individuals in the North Atlantic alone. Today, however, conservation efforts have helped to stabilize and even increase the populations of some bowhead whale subpopulations, particularly in the North Pacific and Canadian Arctic.

"Dolphins" is a common name that refers to several species of marine mammals belonging to the family Delphinidae, within the larger group Cetacea. Dolphins are known for their intelligence, social behavior, and acrobatic displays. They are generally characterized by a streamlined body, a prominent dorsal fin, and a distinctive "smiling" expression created by the curvature of their mouths.

Although "dolphins" is sometimes used to refer to all members of the Delphinidae family, it is important to note that there are several other families within the Cetacea order, including porpoises and whales. Therefore, not all small cetaceans are dolphins.

Some examples of dolphin species include:

1. Bottlenose Dolphin (Tursiops truncatus) - This is the most well-known and studied dolphin species, often featured in aquariums and marine parks. They have a robust body and a prominent, curved dorsal fin.
2. Common Dolphin (Delphinus delphis) - These dolphins are characterized by their hourglass-shaped color pattern and distinct, falcate dorsal fins. There are two subspecies: the short-beaked common dolphin and the long-beaked common dolphin.
3. Spinner Dolphin (Stenella longirostris) - Known for their acrobatic behavior, spinner dolphins have a slender body and a long, thin beak. They are named for their spinning jumps out of the water.
4. Risso's Dolphin (Grampus griseus) - These dolphins have a unique appearance, with a robust body, a prominent dorsal fin, and a distinctive, scarred skin pattern caused by social interactions and encounters with squid, their primary food source.
5. Orca (Orcinus orca) - Also known as the killer whale, orcas are the largest dolphin species and are highly intelligent and social predators. They have a distinctive black-and-white color pattern and a prominent dorsal fin.

In medical terminology, "dolphins" do not have a specific relevance, but they can be used in various contexts such as therapy, research, or education. For instance, dolphin-assisted therapy is an alternative treatment that involves interactions between patients and dolphins to improve psychological and physical well-being. Additionally, marine biologists and researchers study dolphin behavior, communication, and cognition to understand their complex social structures and intelligence better.

Myoglobin is a protein found in the muscle tissue, particularly in red or skeletal muscles. It belongs to the globin family and has a similar structure to hemoglobin, another oxygen-binding protein found in red blood cells. Myoglobin's primary function is to store oxygen within the muscle cells, making it readily available for use during periods of increased oxygen demand, such as during physical exertion.

Myoglobin contains heme groups that bind to and release oxygen molecules. The protein has a higher affinity for oxygen than hemoglobin, allowing it to maintain its bound oxygen even in low-oxygen environments. When muscle cells are damaged or undergo necrosis (cell death), myoglobin is released into the bloodstream and can be detected in serum or urine samples. Elevated levels of myoglobin in the blood or urine may indicate muscle injury, trauma, or diseases affecting muscle integrity, such as rhabdomyolysis or muscular dystrophies.

The term "diving" is generally not used in the context of medical definitions. However, when referring to diving in relation to a medical or physiological context, it usually refers to the act of submerging the body underwater, typically for activities such as swimming, snorkeling, or scuba diving.

In a medical or physiological sense, diving can have specific effects on the human body due to changes in pressure, temperature, and exposure to water. Some of these effects include:

* Changes in lung volume and gas exchange due to increased ambient pressure at depth.
* Decompression sickness (DCS) or nitrogen narcosis, which can occur when dissolved gases form bubbles in the body during ascent from a dive.
* Hypothermia, which can occur if the water is cold and the diver is not adequately insulated.
* Barotrauma, which can occur due to pressure differences between the middle ear or sinuses and the surrounding environment.
* Other medical conditions such as seizures or heart problems can also be exacerbated by diving.

It's important for divers to undergo proper training and certification, follow safe diving practices, and monitor their health before and after dives to minimize the risks associated with diving.

Acoustics is a branch of physics that deals with the study of sound, its production, transmission, and effects. In a medical context, acoustics may refer to the use of sound waves in medical procedures such as:

1. Diagnostic ultrasound: This technique uses high-frequency sound waves to create images of internal organs and tissues. It is commonly used during pregnancy to monitor fetal development, but it can also be used to diagnose a variety of medical conditions, including heart disease, cancer, and musculoskeletal injuries.
2. Therapeutic ultrasound: This technique uses low-frequency sound waves to promote healing and reduce pain and inflammation in muscles, tendons, and ligaments. It is often used to treat soft tissue injuries, arthritis, and other musculoskeletal conditions.
3. Otology: Acoustics also plays a crucial role in the field of otology, which deals with the study and treatment of hearing and balance disorders. The shape, size, and movement of the outer ear, middle ear, and inner ear all affect how sound waves are transmitted and perceived. Abnormalities in any of these structures can lead to hearing loss, tinnitus, or balance problems.

In summary, acoustics is an important field of study in medicine that has applications in diagnosis, therapy, and the understanding of various medical conditions related to sound and hearing.

I'm sorry for any confusion, but the term "Pacific Ocean" is a geographical term referring to the largest single body of saltwater on Earth, extending from the Arctic in the north to the Antarctic in the south. It covers an area of about 63,800,000 square miles (165,200,000 square kilometers).

If you're looking for a medical term or definition, I'd be happy to help with that as well. Could you please provide more context?

Echolocation is a biological sonar system used by certain animals to navigate and locate objects in their environment. It is most commonly associated with bats and dolphins, although some other species such as shrews and cave-dwelling birds also use this method.

In echolocation, the animal emits a series of sounds, often in the form of clicks or chirps, which travel through the air or water until they hit an object. The sound then reflects off the object and returns to the animal, providing information about the distance, size, shape, and location of the object.

By analyzing the time delay between the emission of the sound and the reception of the echo, as well as the frequency changes in the echo caused by the movement of the object or the animal itself, the animal can create a mental image of its surroundings and navigate through it with great precision.

Metmyoglobin is the oxidized form of myoglobin, a protein found in muscle tissue that binds and stores oxygen. When myoglobin is exposed to oxidizing agents or when muscle tissue is damaged (such as during exercise or after death), it can become oxidized and transform into metmyoglobin. This form of the protein cannot bind or store oxygen, and its presence in food (particularly in meats) can lead to off-flavors, discoloration, and reduced shelf life. In medical contexts, metmyoglobin may be used as a marker for muscle damage or hypoxia (lack of oxygen).

I'm sorry for any confusion, but "ships" is not a medical term. It is a common noun referring to large vehicles used for transportation on water. If you have any medical questions or terms you would like defined, I would be happy to help!

I'm sorry for any confusion, but "porpoises" are not a medical term. They refer to a group of marine mammals that are closely related to dolphins. If you have any questions about medical terminology or concepts, I would be happy to help clarify those for you!

Sound spectrography, also known as voice spectrography, is a diagnostic procedure in which a person's speech sounds are analyzed and displayed as a visual pattern called a spectrogram. This test is used to evaluate voice disorders, speech disorders, and hearing problems. It can help identify patterns of sound production and reveal any abnormalities in the vocal tract or hearing mechanism.

During the test, a person is asked to produce specific sounds or sentences, which are then recorded and analyzed by a computer program. The program breaks down the sound waves into their individual frequencies and amplitudes, and displays them as a series of horizontal lines on a graph. The resulting spectrogram shows how the frequencies and amplitudes change over time, providing valuable information about the person's speech patterns and any underlying problems.

Sound spectrography is a useful tool for diagnosing and treating voice and speech disorders, as well as for researching the acoustic properties of human speech. It can also be used to evaluate hearing aids and other assistive listening devices, and to assess the effectiveness of various treatments for hearing loss and other auditory disorders.

Feeding behavior refers to the various actions and mechanisms involved in the intake of food and nutrition for the purpose of sustaining life, growth, and health. This complex process encompasses a coordinated series of activities, including:

1. Food selection: The identification, pursuit, and acquisition of appropriate food sources based on sensory cues (smell, taste, appearance) and individual preferences.
2. Preparation: The manipulation and processing of food to make it suitable for consumption, such as chewing, grinding, or chopping.
3. Ingestion: The act of transferring food from the oral cavity into the digestive system through swallowing.
4. Digestion: The mechanical and chemical breakdown of food within the gastrointestinal tract to facilitate nutrient absorption and eliminate waste products.
5. Assimilation: The uptake and utilization of absorbed nutrients by cells and tissues for energy production, growth, repair, and maintenance.
6. Elimination: The removal of undigested material and waste products from the body through defecation.

Feeding behavior is regulated by a complex interplay between neural, hormonal, and psychological factors that help maintain energy balance and ensure adequate nutrient intake. Disruptions in feeding behavior can lead to various medical conditions, such as malnutrition, obesity, eating disorders, and gastrointestinal motility disorders.

The Extraction and Processing Industry, also known as the extraction industry or the mining sector, is a major category of businesses and economic activities involved in the removal of minerals and other natural resources from the earth. This industry includes several types of extraction operations, such as:

1. Oil and gas extraction: This involves the exploration, drilling, and pumping of crude oil and natural gas from underground reservoirs.
2. Mining: This includes the extraction of various minerals like coal, iron ore, copper, gold, silver, and other metals and non-metallic minerals. There are different methods used for mining, such as surface mining (open-pit or strip mining) and underground mining.
3. Support activities for mining: This category includes services and supplies needed for the extraction of minerals, like drilling, exploration, and mining support services.

After the extraction process, these raw materials undergo further processing to transform them into usable forms, such as refining crude oil into various petroleum products or smelting metals for manufacturing purposes. This processing stage is often included in the definition of the Extraction and Processing Industry.

The medical definition of this industry may not be explicitly stated; however, it indirectly impacts public health and the environment. For instance, mining activities can lead to air and water pollution, exposure to harmful substances, and increased risk of accidents and injuries for workers. Therefore, understanding the Extraction and Processing Industry is essential in addressing potential health hazards associated with these operations.

Animal migration is a seasonal movement of animals from one place to another, typically over long distances, to find food, reproduce, or escape harsh conditions. This phenomenon is observed in various species, including birds, mammals, fish, and insects. The routes and destinations of these migrations are often genetically programmed and can be quite complex. Animal migration has important ecological consequences and is influenced by factors such as climate change, habitat loss, and human activities.

Animal vocalization refers to the production of sound by animals through the use of the vocal organs, such as the larynx in mammals or the syrinx in birds. These sounds can serve various purposes, including communication, expressing emotions, attracting mates, warning others of danger, and establishing territory. The complexity and diversity of animal vocalizations are vast, with some species capable of producing intricate songs or using specific calls to convey different messages. In a broader sense, animal vocalizations can also include sounds produced through other means, such as stridulation in insects.

I'm sorry for any confusion, but "sharks" are not a medical term. Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral and dorsal fins without spines.

If you have any medical questions or terms that you would like defined, I'd be happy to help!

In the context of mental health and psychology, "predatory behavior" is not a term that is commonly used as a medical diagnosis or condition. However, it generally refers to aggressive or exploitative behavior towards others with the intention of taking advantage of them for personal gain or pleasure. This could include various types of harmful behaviors such as sexual harassment, assault, stalking, bullying, or financial exploitation.

In some cases, predatory behavior may be associated with certain mental health conditions, such as antisocial personality disorder or psychopathy, which are characterized by a disregard for the rights and feelings of others. However, it's important to note that not all individuals who engage in predatory behavior have a mental health condition, and many people who do may not necessarily exhibit these behaviors.

If you or someone else is experiencing harm or exploitation, it's important to seek help from a trusted authority figure, such as a healthcare provider, law enforcement officer, or social worker.

"Phocoena" is the genus name for a group of marine mammals commonly known as porpoises. These are small, toothed whales that are characterized by their robust body, short beak, and distinct triangular dorsal fin. The term "Phocoena" specifically refers to a few species within this family, including the harbor porpoise (Phocoena phocoena) and the spectacled porpoise (Phocoena dioptrica). These animals are known for their agile swimming abilities and are found in various parts of the world's oceans.

I'm sorry for any confusion, but "Oceanography" is not a term typically used in medical definitions. Oceanography is the scientific study of the ocean. It involves understanding and describing the ocean's physical and chemical properties, organisms that live there, and the processes that occur within it and at its boundaries with the seafloor and atmosphere.

If you have any questions related to medical terminology or health sciences, I'd be happy to help!

I'm not aware of any medical definitions for "Azores." The Azores is a group of nine volcanic islands in the Atlantic Ocean, located about 850 miles west of Portugal. They are an autonomous region of Portugal and have a population of around 250,000 people. The islands are known for their beautiful landscapes, mild climate, and unique flora and fauna.

If you have any specific questions related to the Azores or if there is something specific you would like to know about the region in a medical context, please let me know and I will do my best to help!

I apologize for any confusion, but "baseball" is not a medical term. It is a sport that involves two teams of nine players each trying to score runs by hitting a ball with a bat and running around four bases on a field. If you have any questions about medical terminology or concepts, I would be happy to help clarify those for you.

Antitrust laws are a set of legal regulations that aim to promote competition and prevent monopolies in markets. These laws prohibit businesses from engaging in restrictive practices designed to reduce competition, such as price-fixing, bid-rigging, and market allocation schemes. Antitrust laws also discourage mergers and acquisitions that may substantially lessen competition or create monopolies. The ultimate goal of antitrust laws is to protect consumers from unfair or deceptive trade practices, promote economic efficiency, and ensure fair and free markets. Some well-known antitrust laws include the Sherman Act, the Clayton Act, and the Federal Trade Commission Act in the United States, and similar laws exist in many other countries around the world.

I apologize, but "Chicago" is not a medical term or concept. Chicago is the largest city in the state of Illinois and the third-most populous city in the United States. It's known for its impressive architecture, vibrant arts scene, and significant contributions to American culture, including jazz music, improvisational theater, and culinary innovations like deep-dish pizza and the Chicago-style hot dog.

If you have any questions related to medical topics or definitions, please feel free to ask!

I'm sorry for any confusion, but "Portraits as Topic" is not a medical term or concept. It refers to portraits, which are visual representations or images of a person, usually showing the face and shoulders. The term "as Topic" indicates that it is the subject or theme being discussed. Therefore, "Portraits as Topic" generally relates to the study, analysis, or discussion of portraits in various contexts, such as art, psychology, sociology, or history. If you have any medical questions or terms you would like me to define, please don't hesitate to ask!

  • A NOAA official calls the recovery of whale numbers in nine of 14 populations 'a true ecological success story. (
  • The move applies to nine of the 14 distinct populations of humpback whales. (
  • So maybe restoring whale populations could also increase the amount of carbon that gets down into deep water and is stored. (
  • But what we do know is that whales help to regulate a huge variety of marine populations, from krill to fish and everything in between because of their voracious appetites, ingenious feeding strategies, and ability to filter feed. (

  • The behavior of these highly gregarious whales, which include sophisticated vocal repertoires, suggest that this marine mammal lives in complex societies. (
  • Whales, including the humpback, serve an important role in our marine environment. (
  • For feeding purposes, these whales tend to tem investigations conducted within 24 hours of death concentrate in specific areas, one of which is Pelagos Sanc- yielded biomolecular and IHC evidence of DMV infec- tuary, the widest protected marine area for sea mammals in tion. (
  • The regulation that big fish and whales provide helps keep marine ecosystems healthy, balanced and resilient. (
  • Once ashore, men slaughter the pilot whales from babies to mature adults in a flurry of blood and spray by severing their spinal cords, cutting through the dorsal area with sharp knives called a grindaknvur. (
  • During the cut of a pilot whales spine, their main arteries are also cut. (
  • You could also become a member of the Pacific Whale Foundation. (
  • All of these whales are considered endangered, with the exception of the gray whale, which recently was removed from the endangered species list, Cranford said. (
  • While recording underwater sounds with hydrophones, the researchers were also taking pictures of the whales as they emerged. (
  • The calf's mother, known as "Infinity" to whale researchers, was also struck and reportedly has not been seen since she was spotted a few days afterward with cuts. (
  • For those with a taste for the icky and gross, Young explores how much researchers can learn from whale feces and snot. (
  • Whales and Dolphins of the World is a celebration of the variety (more than 80 species), behavior, and natural history of these remarkable animals. (
  • For Moore, what looked like a whale hug was more than a curious animal behavior. (
  • Operator vessels should be fit for the purpose, should have a current permit (if required), should be operated so as not to impact the normal behavior of the animals, respect minimum approach distances and speeds, never approach a whale head on, and limit time spent near the animals. (
  • They also differ from the association behavior of the larger toothed whales that informed those predictions. (
  • Humpback whales behavior was observed to determine the existence of differences between observations occurring from research vessels vs. whale-watching vessels. (
  • Fewer than 400 North Atlantic right whales remain in the ocean, making them one of the planet's most critically endangered species. (
  • We also study the critically endangered population of southern right whales that frequent Chile and Peru. (
  • We have documented a number of critically endangered southern right whales entangled in fishing gear. (
  • Humans have an understandable fascination with whales and dolphins, and the best way to see them is in their natural environment, on their terms. (
  • A closing guide to whale species offers a sobering reminder of the terrible toll taken on whales by humans. (
  • It found that the oceans are facing a shortfall of krill, a vital component of the food chain, due to climate change and the recovery of species such as humpback whales. (
  • Investigating "the dynamics of the widely distributed krill population is quite difficult, so that monitoring energy storage by a krill consumer, such as the minke whale, can be most useful," say the authors. (
  • It could be a whole range of things that have nothing to do with amount of krill and whales. (
  • Sperm Whale Mother and Calf. (
  • Beluga whale groupings (beyond mother-calf dyads) were not usually organized around close maternal relatives. (
  • Not only that, but she was the seventh-and last-recorded calf born to a whale called Wart, who had suffered a two-year entanglement that cut into her upper jaw and skull. (
  • In what was likely a once in a lifetime opportunity, a group of amazed whale watchers witnessed a grey whale give birth to a calf near Dana Point off the coast of California. (
  • Given the probability of occurrence of resting conducts in calf pods and the possibility of the interruption of suckling caused by vessels, it is suggested that a more conservative distance and shorter visits be adopted by whale-watching groups. (
  • They were legendary mysteries, the least known of all the whale families, one of the least known of all mammals. (
  • A common and worrying effect of seismic testing was that the whales move away from their normal feeding grounds, Doug Nowacek of Duke University, lead author of the findings published in the journal Aquatic Mammals, said. (
  • HONOLULU - Federal authorities took most humpback whales off the endangered species list Tuesday, saying their numbers have recovered through international efforts to protect the giant mammals. (
  • Typically the whales split into a group of three-one female and two males. (
  • Less than a week later, they were sighted near St. Lucie Inlet, farther south than right whales typically venture. (
  • After most countries reacted angrily to the plan unveiled last week at the annual conference of the International Whaling Commission (IWC) in Panama, the government stepped back, saying it would give up its whaling plan if the international organization rejects it. (
  • The exception is fin whales, which turn on their sides to feed. (
  • In some locations, whales must contend with up to 1,000 boats that move daily through important feeding areas. (
  • In 1815, the naturalist Constantine S. Rafinesque described a new species of cetacean, Balena gastrytis, from Sicily, based on a whale that stranded on Carini beach near Palermo. (
  • The journal remains rare, and awareness of the whale remains minimal, despite its relevance to cetacean taxonomy and understanding of whale diversity and distribution in the Mediterranean. (
  • Protests by the anti-whaling group Sea Shepherd have also contributed to the decline. (
  • Whales are classified into two categories: Those with teeth and those with baleen. (
  • But other species, like the sperm whale , have teeth only on their bottom jaw, which makes it all but impossible to grab their food. (
  • While the beast is about the same size as a current living species of sperm whale, Physeter macrocephalus , its teeth and jaw muscles were much larger. (
  • Others, like humpbacks and blue whales, are "lunge feeders" who take in huge gulps of water that they then push out through smaller baleen to sieve for food. (
  • Recent Examples on the Web By that time, the excessive whaling operations further offshore from Eden had decimated the population of humpbacks and the last baleen whale was processed in Eden in 1928. (
  • He says blubber thickness is "not a very good indicator" of health in whales, recommending instead measuring the ratio of girth or length compared with the ocean giants' weight. (
  • Even though they are large animals, whales can become accidentally caught in fishing nets. (
  • Whales are really big, and make really big feces. (
