Squalus Circulatory System By Leslie Cook and Mark Hatfield (1999) Back to Main Page Along with the organ systems that provide for the metabolic needs of the body, we will consider the circulatory system. Oxygen and food are carried from the respiratory and digestive organs to all the tissues and cells; carbon dioxide and other excretory products are carried from the tissues to sites of removal; hormones are transported from the endocrine glands to the tissues; and heat is distributed throughout the body by the circulatory system. The system also has other functions. It aids in combating disease, repairing tissues, and it helps to maintain the constancy of the internal environment (homeostasis) in many other ways. Refer to (squalusmain) for an overview of the Squalus s circulatory system. Ancestral fishes retain parts, at least, of all six embryonic aortic arches, but the aortic arches are obviously modified in the adults for the interposition of gills and the supply of blood to the head. During ...

The gestation period for embryos of the spiny dogfish, Squalus acanthias (L.) lasts for nearly 2 years. During the latter part of this period the pups remain in the uterus and the fluid surrounding the embryos resembles sea water with respect to the major ions, but is low in pH (approx. 6), high in partial pressure of carbon dioxide (approx. 3 mmHg; 1 mmHg = 133.3 Pa), low in total carbon dioxide content (approx. 0.2 mmol l-1), and may have a total ammonia concentration of up to 22 mmol l-1. Thus the conditions under which the pups complete their development in utero is quite remarkable. The derivation of these conditions was examined in late-term pregnant females, from whose uterine horns the pups had been removed, by monitoring changes that occurred in instilled uterine sea water. The mother is responsible for reducing the pH, reducing the total carbon dioxide content and elevating the partial pressure of carbon dioxide to the levels observed in fresh-caught females, in less than 24 h. The ...

Possibly the most abundant living shark (Ref. 247). An inshore and offshore dogfish of the continental and insular shelf and upper slopes (Ref. 247, 11230). Usually near the bottom, but also in midwater and at the surface (Ref. 26346); occurs mainly between 10-200 m depth (Ref. 247). Males and gravid females usually found shallower than non-gravid females. Tolerates brackish water, often found in enclosed bays and estuaries. Reported to enter freshwater (Ref. 11980) but cannot survive there for more than a few hours (Ref. 247). Highly migratory species, used to be observed in large foraging schools with up to thousands of individuals, usually segregated by size and /or sex, with schools of large gravid females preferentially targeted by fisheries. Their latitudinal (north-south) and depth-related (nearshore-offshore) movements appear to be correlated with their preferred temperature (Ref. 247). Tagging experiments showed that populations in the northern North Sea and northwest Scotland made ...
