A global review of elasmobranch tourism activities, management and risk

Marine Policy, 2020
Elasmobranch tourism is a rapidly expanding global industry. While this industry can provide community and conservation benefits, it presents risks to target species, environments and humans when inappropriately managed.

Corticosteroids in plasma of elasmobranchs

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. Free corticosteroids were quantified by double isotope derivative assay in thirteen plasma samples from seven species of elasmobranchs. 2. 2. In each instance, four batoids and three selachians, 1α-hydroxycortico-sterone was the principal plasmatic corticosteroid. 3. 3.

Forebrain Organization in Elasmobranchs

Brain, Behavior and Evolution, 2012
It has long been known that many elasmobranch fishes have relatively large brains. The telencephalon, in particular, has increased in size in several groups, and as a percent of total brain weight, it is as large as in some mammals. Little is known, however, about the organization, connections, and functions of the telencephalon in elasmobranchs. Early

Electrophysiology of the Elasmobranch Stomach

Science, 1959
A consequence of the recent study of the mechanism of gastric secretion has been the presumption, implicit ( 1 ) if not explicit ( 2 ), that the distinctive gastric transmucosal potential has a fundamental role in the formation of hydrochloric acid.

Thyroglobulins of cyclostomes and an elasmobranch

General and Comparative Endocrinology, 1975
Abstract As part of a study of the biosynthesis and physicochemical properties of primitive vertebrate thyroglobulins, the thyroid-containing tissues of Pacific hagfish (Eptatretus stouti) and of Pacific lamprey (Entosphenus tridentatus), and thyroid glands of Pacific dogfish (Squalus suckleyi) were used.

Ureogenesis in Elasmobranchs

Nature, 1958
So long ago as 1858, Staedeler and Frerichs1 discovered the presence of large amounts of urea in three species of elasmobranch fishes. Many more have been examined since that time, and it is known to-day that many, and probably all marine, elasmobranchs, including the Holocephali, contain 2–2.5 per cent of urea in their blood and tissues.
