GABAergic excitatory synapses and electrical coupling sustain prolonged discharges in the prey capture neural network of Clione limacina. (1/1395)

Afterdischarges represent a prominent characteristic of the neural network that controls prey capture reactions in the carnivorous mollusc Clione limacina. Their main functional implication is transformation of a brief sensory input from a prey into a lasting prey capture response. The present study, which focuses on the neuronal mechanisms of afterdischarges, demonstrates that a single pair of interneurons [cerebral A interneuron (Cr-Aint)] is responsible for afterdischarge generation in the network. Cr-Aint neurons are electrically coupled to all other neurons in the network and produce slow excitatory synaptic inputs to them. This excitatory transmission is found to be GABAergic, which is demonstrated by the use of GABA antagonists, uptake inhibitors, and double-labeling experiments showing that Cr-Aint neurons are GABA-immunoreactive. The Cr-Aint neurons organize three different pathways in the prey capture network, which provide positive feedback necessary for sustaining prolonged spike activity. The first pathway includes electrical coupling and slow chemical transmission from the Cr-Aint neurons to all other neurons in the network. The second feedback is based on excitatory reciprocal connections between contralateral interneurons. Recurrent excitation via the contralateral cell can sustain prolonged interneuron firing, which then drives the activity of all other cells in the network. The third positive feedback is represented by prominent afterdepolarizing potentials after individual spikes in the Cr-Aint neurons. Afterdepolarizations apparently represent recurrent GABAergic excitatory inputs. It is suggested here that these afterdepolarizing potentials are produced by GABAergic excitatory autapses.  (+info)

Determination of the anomeric configurations of Corbicula ceramide di- and trihexoside by chromium trioxide oxidation. (2/1395)

The anomeric configurations of Corbicula ceramide dihexoside and ceramide trihexoside were determined by chromium trioxide oxidation and the structures of these lipids were shown to be Man-beta(1 leads to 4)-Glc-beta(1 leads to 1)-ceramide and Man-alpha(1 leads to 4)-Man-beta(1 leads to 4)-Glc-beta(1 leads to 1)-ceramide. These results are compatible with those obtained by enzymic hydrolysis reported previously.  (+info)

Central pattern generator for escape swimming in the notaspid sea slug Pleurobranchaea californica. (3/1395)

Escape swimming in the notaspid opisthobranch Pleurobranchaea is an episode of alternating dorsal and ventral body flexions that overrides all other behaviors. We have explored the structure of the central pattern generator (CPG) in the cerebropleural ganglion as part of a study of neural network interactions underlying decision making in normal behavior. The CPG comprises at least eight bilaterally paired interneurons, each of which contributes and is phase-locked to the swim rhythm. Dorsal flexion is mediated by hemiganglion ensembles of four serotonin-immunoreactive neurons, the As1, As2, As3, and As4, and an electrically coupled pair, the A1 and A10 cells. When stimulated, A10 commands fictive swimming in the isolated CNS and actual swimming behavior in whole animals. As1-4 provide prolonged, neuromodulatory excitation enhancing dorsal flexion bursts and swim cycle number. Ventral flexion is mediated by the A3 cell and a ventral swim interneuron, IVS, the soma of which is yet unlocated. Initiation of a swim episode begins with persistent firing in A10, followed by recruitment of As1-4 and A1 into dorsal flexion. Recurrent excitation within the As1-4 ensemble and with A1/A10 may reinforce coactivity. Synchrony among swim interneuron partners and bilateral coordination is promoted by electrical coupling among the A1/A10 and As4 pairs, and among unilateral As2-4, and reciprocal chemical excitation between contralateral As1-4 groups. The switch from dorsal to ventral flexion coincides with delayed recruitment of A3, which is coupled electrically to A1, and with recurrent inhibition from A3/IVS to A1/A10. The alternating phase relation may be reinforced by reciprocal inhibition between As1-4 and IVS. Pleurobranchaea's swim resembles that of the nudibranch Tritonia; we find that the CPGs are similar in many details, suggesting that the behavior and network are primitive characters derived from a common pleurobranchid ancestor.  (+info)

A novel small protein associated with a conjugated trienoic chromophore from membranes of scallop adductor muscle: phosphorylation by protein kinase A. (4/1395)

Membranes enriched in sarcolemma from the cross-striated adductor muscle of the deep sea scallop have been found to contain a previously undescribed small protein of 6-8 kDa that can be released by treatment with organic solvent mixtures. This proteolipid co-purified with a non-amino acid chromophore containing a conjugated trienoic moiety. Although common in plants and algae, such a stable conjugated trienoic group is unusual for an animal cell. The N-terminal amino acid sequence of the protein was XEFQHGLFGXF/ADNIGLQ, which most strongly resembles sequences in the triacyl glycerol lipase precursor and the product of the human breast cancer susceptibility gene BRCA 1, but does not show similarity to previously described proteolipids. The protein was found to be one of the major substrates in its parent membrane for the catalytic subunit of protein kinase A, which may imply a regulatory function for this molecule.  (+info)

Osmotic adjustment in an estuarine population of Urosalpinx cinerea (Say, 1822) (Muricidae, Gastropoda). (5/1395)

Individuals from a subtidal, estuarine population of the common oyster drill, Urosalpinx cinerea (Say, 1822), were brought into the laboratory and tested for osmotic adjustment to changing salinity. Tissue variables monitored at seven experimental salinities ranging from 10 to 40% were tissue fluid osmolality, chloride, sodium, potassium, free amino acids (FAA), ninhydrin-positive substances (NPS) and water content. The results of this study demonstrate that the test animals did not exhibit anisosmotic regulation at any of the experimental salinities. However, the data do suggest a high degree of hyper-ionic regulation of potassium at all experimental salinities and a hyporegulation of sodium between the 25 and 40% salinities. Taurine, aspartic acid, alanine and glycine were the four FAA present in relatively consistent high amounts. These four amino acids comprised from 59.6 to 75.7% of the total FAA pools. It is postulated that the population does not maintain its euryhaline survival status through an osmoregulatory mechanism. Rather, the population has probably adapted physiologically to withstand dilution of its body fluids during spring conditions of low salinities.  (+info)

Fluorescence measurements detect changes in scallop myosin regulatory domain. (6/1395)

Ca2+-induced conformational changes of scallop myosin regulatory domain (RD) were studied using intrinsic fluorescence. Both the intensity and anisotropy of tryptophan fluorescence decreased significantly upon removal of Ca2+. By making a mutant RD we found that the Ca2+-induced fluorescence change is due mainly to Trp21 of the essential light chain which is located at the unusual Ca2+-binding EF-hand motif of the first domain. This result suggests that Trp21 is in a less hydrophobic and more flexible environment in the Ca2+-free state, supporting a model for regulation based on the 2 A resolution structure of scallop RD with bound Ca2+ [Houdusse A. and Cohen C. (1996) Structure 4, 21-32]. Binding of the fluorescent probe, 8-anilinonaphthalene-1-sulphonate (ANS) to the RD senses the dissociation of the regulatory light chain (RLC) in the presence of EDTA, by energy transfer from a tryptophan cluster (Trp818, 824, 826, 827) on the heavy chain (HC). We identified a hydrophobic pentapeptide (Leu836-Ala840) at the head-rod junction which is required for the effective energy transfer and conceivably is part of the ANS-binding site. Extension of the HC component of RD towards the rod region results in a larger ANS response, presumably indicating changes in HC-RLC interactions, which might be crucial for the regulatory function of scallop myosin.  (+info)

The occurrence of two types of collagen proalpha-chain in the abalone Haliotis discus muscle. (7/1395)

Acid-soluble collagens were prepared from connective tissues in the abalone Haliotis discus foot and adductor muscles with limited proteolysis using pepsin. Collagen preparation solubilized with 1% pepsin contained two types of alpha-chains which were different in their N-terminal amino acid sequences. Accordingly, two types of full-length cDNAs coding for collagen proalpha-chains were isolated from the foot muscle of the same animal and these proteins were named Hdcols (Haliotis discus collagens) 1alpha and 2alpha. The two N-terminal amino acid sequences of the abalone pepsin-solubilized collagen preparation corresponded to either of the two sequences deduced from the cDNA clones. In addition, several tryptic peptides prepared from the pepsin-solubilized collagen and fractionated by HPLC showed N-terminal amino acid sequences identical to those deduced from the two cDNA clones. Hdcols 1alpha and 2alpha consisted of 1378 and 1439 amino acids, respectively, showing the primary structure typical to those of fibril-forming collagens. The N-terminal propeptides of the two collagen proalpha-chains contained cysteine-rich globular domains. It is of note that Hdcol 1alpha completely lacked a short Gly-X-Y triplet repeat sequence in its propeptide. An unusual structure such as this has never before been reported for any fibril-forming collagen. The main triple-helical domains for both chains consisted of 1014 amino acids, where a supposed glycine residue in the triplet at the 598th position from the N-terminus was replaced by alanine in Hdcol 1alpha and by serine in Hdcol 2alpha. Both proalpha-chains of abalone collagens contained six cysteine residues in the carboxyl-terminal propeptide, lacking two cysteine residues usually found in vertebrate collagens. Northern blot analysis demonstrated that the mRNA levels of Hdcols 1alpha and 2alpha in various tissues including muscles were similar to each other.  (+info)

Continuous in vitro propagation and differentiation of cultures of the intramolluscan stages of the human parasite Schistosoma mansoni. (8/1395)

The metazoan parasitic blood flukes, Schistosoma spp., infect over 200 million people worldwide and cause extensive human morbidity and mortality. Research strategies for development of anti-schistosomal agents are impeded by the organism's complex molluscan-mammalian life cycle, which limits experimental approaches and availability of material. We derived long-term continuously proliferative cultures of Schistosoma mansoni sporocysts capable of generating cercariae in vitro. Cultured organisms retained the ability to parasitize the host, and they exhibited developmental regulation of candidate stage-specific genes in the host-free culture system. Evidence for expression of a reverse transcriptase also was found in the cultured organisms, pointing to this activity as a possible mechanistic contributor to the dynamic relationship between the parasite and its hosts. Continuous in vitro propagation of the asexual sporocyst stage allows isolation of clonally derived parasite populations and provides a means to study schistosomal molecular genetics, metabolism, and evasion of host defenses.  (+info)

By Glynn, Peter W Enochs, Ian C; McCosker, John E; Graefe, Abigail N Abstract: Adult individuals of the pearlfish Carapus mourlani (Petit, 1934) occur commonly in the mantle cavity of the opisthobranch mollusc Dolabella auricularia (Lightfoot, 1786) in shallow marine waters of the Gulf of Chiriqui, Pacific Panama. Nearly 30% of the molluscan hosts collected during the day on a coral reef contained one or two fish. Feeding observations of a captive fish as well as the intact condition of the hosts ctenidium and other internal organs suggest that C. mourlani is an inquiline commensal and not parasitic. Fish curl around the ctenidium during the day and capture microcrustaceans when the fish emerge from their host at night to feed. From low-light infrared video recordings, Carapus was observed to accurately grasp rapidly swimming amphipods in nearly total darkness and ingest them. This symbiotic relationship appears to benefit Carapus by allowing the fish to avoid predators during the day and to ...

Abstract: The central nervous system (CNS) of a metamorphically competent larva of the caenogastropod Ilyanassa obsoleta contains a medial, unpaired apical ganglion (AG) of approximately 25 neurons that lies above the commissure connecting the paired cerebral ganglia. The AG, also known as the cephalic or apical sensory organ (ASO), contains numerous sensory neurons and innervates the ciliated velar lobes, the larval swimming and feeding structures. Before metamorphosis, the AG contains 5 serotonergic neurons and exogenous serotonin can induce metamorphosis in competent larvae. The AG appears to be a purely larval structure as it disappears within 3 days of metamorphic induction. In competent larvae, most neurons of the AG display nitric oxide synthase (NOS)-like immunoreactivity and inhibition of NOS activity can induce larval metamorphose. Because nitric oxide (NO) can prevent cells from undergoing apoptosis, a form of programmed cell death (PCD), we hypothesize that inhibition of NOS activity ...
Abstract: The apical ganglion (AG) of larval caenogastropods, such as Ilyanassa obsoleta, houses a sensory organ, contains five serotonergic neurons, innervates the muscular and ciliary components of the velum, and sends neurites into a neuropil that lies atop the cerebral commissure. During metamorphosis, the AG is lost. This loss had been postulated to occur through some form of programmed cell death (PCD), but it is possible for cells within the AG to be respecified or to migrate into adjacent ganglia. Evidence from histological sections is supported by results from a terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, which indicate that cells of the AG degenerate by PCD. PCD occurs after metamorphic induction by serotonin or by inhibition of nitric oxide synthase (NOS) activity. Cellular degeneration and nuclear condensation and loss were observed within 12 h of metamorphic induction by NOS inhibition and occur before loss of the velar lobes, the ciliated tissue used ...
Introduction. A2 Biology Investigation Comparing the mean ratios of shell height/diameter of the Patella spp on an exposed and sheltered shore Rebekah Riley Candidate number: 5037 Centre number: 28384 Background Information Limpets are slow moving molluscs, characteristic of rocky shores and are very well adapted to life on the seashore. They have a hard shell to protect themselves against predators and damage from moving rocks, and a large muscular foot that enables them to clamp firmly onto rocks to conserve water and maintain their position during rough weather. The most common limpet is Patella vulgata. The conical shell of Patella vulgata can be up to 6 cm long with radiating ridges and the apex central or slightly anterior. Orton (1928) has shown that individuals that inhabit the upper shore generally have a taller shell and smaller shell length when compared to juveniles and lower shore organisms. The thickness of shells is believed to be concerned with heat insulation and water ...

The top picture shows polar lobe formation during the first cell division. One can see two polar bodies. Polar bodies are the tiny sister cells of the oocyte which are produced during meiosis, contain discarded DNA and mark the animal pole of the embryo (up in the first three pictures). The opposite pole of the embryo is the vegetal pole. The two cells at the animal pole are the first two blastomeres. What looks like a third cell at the vegetal pole is the polar lobe, which at this stage is nearly completely cinched off from either blastomere. Subsequently the polar lobe fuses with one of the blastomeres (second picture from top), so that by the end of the first cell division one of the blastomeres (called CD) is noticeably larger than the AB cell (third picture from top). Polar lobe also forms at the second cell division (not shown). At the four-cell stage blastomere D is the largest, blastomere C is the second largest, while A and B cells are about the same size (bottom picture). The first ...
Desomorphine, the principal opioid in Krokodil, has an analgesic potency approximately ten-times that of morphine. Similar to other opioids, during phase II metabolism it undergoes conjugation with glucuronic acid to form desomorphine-glucuronide. Deconjugation efficiencies using chemical and enzymatic hydrolysis were evaluated and stability in aqueous solution was assessed. Acid hydrolysis was compared with five -glucuronidase sources (BGTurbo, IMCSzyme, Escherichia coli, Helix pomatia and Patella vulgata). At optimal conditions, each hydrolysis method produced complete hydrolysis (96 percent); however, under simulated challenging conditions, P. vulgata was the most efficient -glucuronidase for the hydrolysis of desomorphine-glucuronide. Both BGTurbo and IMCSzyme offered fast hydrolysis with no need for sample cleanup prior to liquid chromatography-quadrupole/time of flight-mass spectrometry (LC-Q/TOF-MS) analysis. Hydrolysates using E. coli, H. pomatia, and P. vulgata underwent additional ...

Paua is a New Zealand summer delicacy. When someone says paua fritter they are usually referring to something made from blackfoot paua. The blackfoot paua (Haliotis iris) species is endemic to New Zealand and found throughout the country. It is most abundant on shallow reefs.. Paua belong to a group of primitive gastropod molluscs known as abalone. Worldwide there are about 55 species.. Three species of abalone occur in New Zealand: blackfoot paua (Haliotis iris), yellowfoot paua (Haliotis australis), and whitefoot paua (Haliotis virginea).. Blackfoot paua has a beautifully coloured shell; haliotis means sea ear and iris refers to the rainbow colour.. The hard shell is well adapted to living on rocks being battered by big surf. Although most paua live in water less than 10 metres deep, they may be found down to 15 metres, particularly in places exposed to large oceanic swells.. They feed by the backwards and forwards motion of their ribbon-like tongue and 100-150 rows of teeth. Small paua rasp ...

Cemadotin, also known as, LU103793, is a mitosis inhibitor potentially for the treatment of solid tumours. Cemadotin is also a synthetic derivative of Dolastatin 15, an antiproliferative compound which was isolated from the mollusk Dolabella auricularia. Like Dolastatin 15, LU103793 is highly cytotoxic in vitro (IC50 = 0.1 nM). LU103793 inhibits microtubule polymerization in a concentration-dependent manner (IC50 = 7 microM). Treatment with this compound also induced depolymerization of preassembled microtubules. Cell cycle analysis of tumor cell lines treated with LU103793 indicated a block in the G2-M phase.

Elysia chlorotica is not an ordinary sea slug (a mollusc). Elysia chlorotica is a photosynthetic sea animal. Like plants, it is capable of converting sunlight into energy.. The photosynthetic ability of Elysia chlorotica is the result of incorporation of algal (Vaucheria litorea) chloroplasts (organelles found in plant cells in which photosynthesis occurs) and chlorophyll producing genes into its molluscan cells. Vaucheria litorea belongs to the yellow-green algae of the class Xanthophyceae.. These slugs initially got the chlorophyll producing genes from the algae that they had eaten. Present generations of slugs have received these genes from their parent generations, and they are passing them to their daughter generations.. Elysia chlorotica gets its chlorophyll-making genes through genetic inheritance, but still is unable to carry out photosynthesis until it consumes adequate quantity of algae so as to receive necessary chloroplasts, which it is unable to produce by itself.. ...
The effect of dietary substitution of casein with fishmeal, soybean meal and crustacean meal on the growth of the abalone Haliotis discus hannai Ino was determined. A 350 g casein per kilogram diet was included into the CS diet. The whole casein was then substituted by: (1) 300 g fishmeal and 200 g soybean meal per kilogram diet (FS), (2) 200 g fishmeal, 200 g soybean meal and 130 g krill meal per kilogram diet (FSK), (3) 200 g fishmeal, 200 g soybean meal and 280 g red crab meal per kilogram diet (FSC) or (4) 200 g fishmeal, 200 g soybean meal and 130 g shrimp head meal per kilogram diet (FSS). In addition, a 50-g by-product of green tea per kilogram diet was included in the FS diet to form the FSG diet. Sea tangle (ST)diet was supplied to abalone as a control feed.

The adductor muscles are the main muscular system in bivalve mollusks, i.e. in clams, scallops, mussels, oysters, etc. In many parts of the world, when people eat scallops, the adductor muscles are the only part of the soft parts of the animal which are eaten. Adductor muscles leave noticeable scars or marks on the interior of the shells valves. Those marks (known as adductor muscle scars) are often used by scientists who are in the process of identifying empty shells to determine their correct taxonomic placement. Bivalve mollusks generally have either one or two adductor muscles. The muscles are strong enough to close the valves of the shell when they contract, and they are what enable the animal to close its valves tightly when necessary, such as when the bivalve is exposed to the air by low water levels, or when it is attacked by a predator. Most bivalve species have two adductor muscles, which are located on the anterior and posterior sides of the body.[1] Some families of bivalves have ...
Hypoxia and hyperthermia are two connected consequences of the ongoing global change that constitute major threats for coastal marine organisms. In the present study, we used a proteomic approach to characterize the changes induced by hypoxia in individuals of the great scallop, Pecten maximus, subjected to three different temperatures, i.e. 10°C, 18°C and 25°C. We did not observe any significant change induced by hypoxia in animals acclimated at 10°C. Contrastingly at 18°C and 25°C, 16 and 11 protein spots were differentially accumulated between normoxia and hypoxia, respectively. Moreover, biochemical data, i.e. octopine dehydrogenase activity and arginine assays suggests that animals grown at 25°C switched their metabolism towards anaerobic metabolism when exposed to either normoxia or hypoxia, suggesting that this temperature is out of the scallops optimal thermal window. In all, 11 proteins could be unambiguously identified by mass spectrometry, involved in protein modifications and
The king scallop Pecten maximus is a high valuable species of great interest in Europe for both fishery and aquaculture. Notably, there has been an increased investment to produce seed for enhancement programmes of wild scallop populations. However, hatchery production is a relatively new industry and it is still underdeveloped. Major hurdles are spawning control and gamete quality. In the present study, a total of 14 scallops were sampled in the bay of Brest (Brittany, France) to compare transcriptomic profiles of mature oocytes collected by spawning induction or by stripping. To reach such a goal, a microarray analysis was performed by using a custom 8x60K oligonucleotide microarray representing 45,488 unique scallop contigs. First we identified genes that were differentially expressed depending on oocyte quality, estimated as the potential to produce D-larvae. Secondly, we investigated the transcriptional features of both stripped and spawned oocytes. Genes coding for proteins involved in
In order to investigate the mechanisms of final maturation and capacitation of spermatozoa in Pecten maximus, we used a 2D proteomic approach coupled with MALDI-TOF/TOF mass spectrometry (MS) and bioinformatics search against the Pecten database, to set up a reference map of the proteome of spawned spermatozoa, and identified 133 proteins on the basis of the EST database. These proteins are mainly involved in energy production, ion and electron transport (44%), cell movement (22%) and developmental processes (10%). Comparison between proteomes of spermatozoa collected before and after transit through the genital ducts of P. maximus led to the identification of differentially expressed proteins. Most of them are associated with energy metabolism (aconitate hydratase, malate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase), indicating important modifications of energy production during transit in gonoducts, potentially linked with acquisition of sperm motility. Three proteins involved in ...

The pedal ganglia are connected to other ganglia through large connectives: the Pedal-Pleural connective and the Cerebro-Pedal connective. In addition, there are two commissures that connect the left and right pedal ganglia: the large commissure is known simply as the Pedal Commissure, the smaller, more anterior commissure is called the parapedal commissure. The nerves leaving the pedal ganglion are numbered in an anterior to posterior fashion (P1-P10). Unlike the other nerves, P10 is a midline nerve that exits from the parapedal commissure. Cobalt backfilling of the 9 paired nerves by Hening et al., 1979, indicates that each nerve contains axons of neurons from several cell clusters that are dispersed through the ganglion. ...

The lack of homogeneity in field application of Bacillus thuringiensis formulation often results in ingestion of sub-lethal doses of the biopesticide by a fraction of pest population and there by promotes the toxin tolerance and resistance in long term. Gut regeneration seems to be one of the possible mechanism by which this is accomplished. However, the existing information is primarily derived from in vitro studies using mid-gut cell cultures. Present study illustrates cellular and molecular changes in mid-gut epithelium of a Bt-susceptible polyphagous insect pest castor semilooper, Achaea janata in response to a Cry toxin formulation. The present report showed that prolonged exposure to sub-lethal doses of Cry toxin formulation has deleterious effect on larval growth and development. Histological analysis of mid-gut tissue exhibits epithelial cell degeneration, which is due to necrotic form of cell death followed by regeneration through enhanced proliferation of mid-gut stem cells. Cell death is
Arginine kinase (AK), an important member of the phosphokinase family, is involved in temporal and spatial adenosine triphosphate (ATP) buffering systems. AK plays an important role in physiological function and metabolic regulations, in particular tissues with high and fluctuating energy demands. In present study, four AK genes were firstly identified from Yesso scallop (Patinopecten yessoensis) genome, respectively named PyAK1-4. PyAKs have highly conserved structures with a six-exon/five-exon structure, except for PyAK3. PyAK3 contains an unusual two-domain structure and a bridge intron between the two domains, which may originate from gene duplication and subsequent fusion. Phylogenetic analysis showed that all PyAKs belonged to an AK supercluster together with other AK proteins from Mollusca, Platyhelminthes, Arthropoda, and Nematode. A transcriptome database demonstrated that PyAK3 and PyAK4 were the main functional executors with high expression level during larval development and in ...
It can be seen from the available mollusk mitogenomes that the family Pectinidae exhibits the most variation in genome organization. In this study, comparative mitogenomic analyses were performed for three scallops from the subfamily Chlamydinae (Pectinidae), with the goal of characterizing the degree of variability of mitogenome organization and other characteristics among species from the same subfamily and exploring their possible evolution route. The complete or nearly complete mtDNA sequences of scallop Mimachlamys nobilis (17 935 bp), Mizuhopecten yessoensis (20 964 bp) and Chlamys farreri (17 035 bp) were determined using long PCR amplification and primer walking sequencing strategy. Highly variable size difference of the three genomes resulted primarily from length and number variations of non-coding regions, and the major difference in gene content of the three scallop species are due to varying tRNA gene sets. Only 21, 16, and 17 tRNA genes were detected in the mitogenomes of M. nobilis, M.

Ferritin cores from human spleen, limpet (Patella vulgata) haemolymph and bacterial (Pseudomonasaeruginosa) cells have been investigated using 57Fe Mössbauer spectroscopy. The Mössbauer spectra were recorded over a range of temperatures from 1.3 to 78 K. At 78 K, all the spectra are quadrupole-split doublets with similar quadrupole splittings and isomer shifts, characteristic of iron(III), while at sufficiently low temperatures the spectra of all the samples show well-resolved magnetic splitting. At intermediate temperatures, the spectra from the human ferritin exhibit typical superparamagnetic behaviour, while those from the bacterial ferritin show behaviour corresponding to a transition from a magnetically ordered to a paramagnetic state. The spectra from the limpet ferritin show a complex combination of the two effects. The results are discussed in terms of the magnetic behaviour of small particles. The data are consistent with magnetic ordering temperatures of about 3 and 30 K for the ...

Pāua are gathered recreationally and commercially but strict catch limits are set for both. For recreational fishermen this is ten pāua per person per day. The minimum legal size for caught pāua is 125 mm for Haliotis iris and 80 mm for Haliotis australis, measured in a straight line at the greatest length of the shell.[2] The exception is Haliotis iris taken from the Amateur Taranaki Paua Fishery Area, which is the area of Taranaki coast bounded by the Awakino River in the north and the Whanganui River in the south, in which the minimum legal size is 85 mm. However, pāua caught in this area cannot be taken east of State Highway 4 unless they meet the 125 mm limit.[3] In addition, no single person may have in their possession at any time (including on land) more than 20 pāua or more than 2.5 kg of shucked (shell removed) pāua. Pāua can only be caught by free diving; it is illegal to dive for pāua using scuba equipment. All pāua must remain un-shucked until they are on the land side of ...
Molluscs are a diverse animal phylum with a formidable fossil record. Although there is little doubt about the monophyly of the eight extant classes, relationships between these groups are controversial. We analysed a comprehensive multilocus molecular data set for molluscs, the first to include multiple species from all classes, including five monoplacophorans in both extant families. Our analyses of five markers resolve two major clades: the first includes gastropods and bivalves sister to Serialia (monoplacophorans and chitons), and the second comprises scaphopods sister to aplacophorans and cephalopods. Traditional groupings such as Testaria, Aculifera, and Conchifera are rejected by our data with significant Approximately Unbiased (AU) test values. A new molecular clock indicates that molluscs had a terminal Precambrian origin with rapid divergence of all eight extant classes in the Cambrian. The recovery of Serialia as a derived, Late Cambrian clade is potentially in line with the ...

Serotonin (5-HT) applied to the exposed but otherwise intact nervous system results in enhanced excitability of Hermissenda type-B photoreceptors. Several ion currents in the type-B photoreceptors are modulated by 5-HT, including the A-type K+ current (IK,A), sustained Ca2+ current (ICa,S), Ca-dependent K+ current (IK,Ca), and a hyperpolarization-activated inward rectifier current (Ih). In this study,we developed a computational model that reproduces physiological characteristics of type B photoreceptors, e.g. resting membrane potential, dark-adapted spike activity, spike width, and the amplitude difference between somatic and axonal spikes. We then used the model to investigate the contribution of different ion currents modulated by 5-HT to the magnitudes of enhanced excitability produced by 5-HT.

Nearly all octopuses are predatory; bottom-dwelling octopuses eat mainly crustaceans, polychaete worms, and other molluscs such as whelks and clams; open-ocean octopuses eat mainly prawns, fish and other cephalopods.[71] Major items in the diet of the giant Pacific octopus include bivalve molluscs such as the cockle Clinocardium nuttallii, clams and scallops, and crustaceans such as crabs and spider crabs. Prey that it is likely to reject include moon snails, because they are too large, and limpets, rock scallops, chitons and abalone, because they are too securely fixed to the rock.[70]. A bottom-dwelling octopus typically moves among the rocks and feels through the crevices. The creature may make a jet-propelled pounce on prey and pull it towards the mouth with its arms, the suckers restraining it. Small prey may be completely trapped by the webbed structure. Octopuses usually inject crustaceans like crabs with a paralysing saliva then dismember them with their beaks.[71][72] Octopuses feed on ...
Even if weather permits boats to go out fishing, fishermen are only able to harvest if the air temperature is above 28 degrees before 10AM. ‍. Thats because the water is warmer than the air, and when bringing the scallops on board their boats, the fishermen must sort through them and return the juvenile scallops. If the air is lower than 28 degrees, the juvenile scallops will freeze and die. These restrictions on fishing are important to help support the fisherys sustainability. ‍ ...

And the scallop… well, now. It may close its shells, an event truly worth a negative number on the excitement scale. However, if one has been blessed by the fates, a scallop may actually swim (!) by rapidly clapping its valves together a few times. This actually IS exciting. Of course, probably the main reason for any excitement is that the behavior happens so rarely and it is compared to all of the other apparently non-interesting things happening in the vacinity. Normally, Patinopecten scallops are the epitome of dull. An individual spends its life in its little mud depression filtering water to obtain the phytoplankton it eats. Of course, a fair-sized clam such as fully-grown weathervane scallop contains a large mass of delicious muscles along with other nutritious innards. Consequently, the scallop is desirable prey item for any number of predators, including sea stars. Presumably as a result, natural selection has given the scallop its rather spectacular swimming escape response. If its ...
This report is concerned with several aspects of the process of iron mineralization of the radula teeth of chitons (Polyplacophora.. In Part I, the cusp cells of the radula sac, which are responsible for the deposition of iron into the major lateral teeth, are studied with the electron microscope. In Mopalia muscosa and Lepidochitona (Cyanoplax) hartwegi, it is found that these cells extend from a dorsal blood sinus to the surface of the teeth. The basal ends of the cusp cells, near the dorsal sinus, contain numerous rhopheocytotic vesicles filled with ferritin. Near the apical ends of the cells, there is a high concentration of iron-containing membrane-bound granules. Some granules contain ferritin, others are filled with ferruginous particles of electron-dense material, and others contain ferritin cores with an outer layer of ferruginous particles. In each cusp cell, the granule region is separated from the tooth surface by a bundle of microvilli that arises from a layer of mitochondria-rich ...

Opisthobranch molluscs exhibit fascinating body plans associated with the evolution of shell loss in multiple lineages. Sea hares in particular are interesting because Aplysia californica is a well-studied model organism that offers a large suite of genetic tools. Bursatella leachii is a related tropical sea hare that lacks a shell as an adult and therefore lends itself to comparative analysis with A. californica. We have established an enhanced culturing procedure for B. leachii in husbandry that enabled the study of shell formation and loss in this lineage with respect to A. californica life staging.
Researcher Charles H. Peterson recently heard fishermen in North Carolina complaining that cownose rays were eating up all the regions bay scallops. He and his colleagues at the University of North Carolinas Institute of Marine Sciences at Morehead City decided to test whether this was really happening.. To keep rays from eating scallops in certain areas, the scientists put a protective ring of poles around the scallops. Rays are wider than most sea creatures and wont usually swim between poles that are spaced closely together. (The rays could turn sideways and fit through, but they dont usually do this.) Other animals, however, swim easily through the gaps between poles.. In 2002 and 2003, at the beginning of the fall season, researchers found populations of bay scallops that were healthy and dense. But after rays migrated through, the scallops nearly disappeared in areas that were not surrounded by poles. Within protected areas, only half of the scallops were gone. Its not even certain ...

Character analysis is performed based on anatomical information on 95 species of Sacoglossa (Mollusca, Opisthobranchia). Functional and developmental information is included, where available. Phylogenetic analysis to generic level is performed. The shelled Oxynoacea is a monophyletic group containing three families, Volvatellidae, Juliidae and Oxynoidae. The family Cylindrobullidae is excluded from the Sacoglossa, but forms a sister taxon. The non-shelled Placobranchacea is also a monophyletic group composed of two monophyletic superfamilies, Placobranchoidea (= Elysioidea) and Limapontioidea (= Stiligeroidea; = Polybranchoidea). Relationships among most genera included in the Placobranchoidea remain unresolved. The family Boselliidae is retained until further examination of the included species has shown whether it should be included in the Placobranchidae. The Platyhedylidae, comprising the genera Platyhedyle and Gascoignella, is included in the Placobranchoidea. Of the families included in ...

Members of the class Polychaeta are mostly gonochoric (sexual). Mating: Females produce a pheromone attracting and signalling the males to shed sperm which in turn stimulates females to shed eggs, this behavior is known as swarming. Gametes are spawned through the metanephridia or body wall rupturing (termed as epitoky, wherein a pelagic, reproductive individual, epitoke, is formed from a benthic, nonreproductive individual, atoke). After fertilization, most eggs become planktonic; although some are retained in the worm tubes or burrowed in jelly masses attached to the tubes (egg brooders). Life Cycle: Eggs develop into trocophore larva, which later metamorph into juvenile stage (body lengthened), and later develop into adults (Ref. 833). ...
