Comparative hemostasis: Studies on elasmobranchs
Comparative Biochemistry and Physiology Part A: Physiology, 1972Abstract 1. 1. Elasmobranch blood contains thrombocytes, which are agglutinated by thrombin but not by ADP. Dogfish thrombocytes appear to adhere to dogfish collagen. 2. 2. Elasmobranch blood clots very slowly often being still uncoagulated after 48 hr. 3. 3. Adding calcium accelerates elasmobranch clotting.

Few studies of sex differentiation in elasmobranchs exist. Chieffi's comparative work on Torpedo ocel/ata, T. marmora/a, and Scy!iorhinus canicula are the most complete, and his comparisons with other published accounts of sex differentiation (Picon 1962) show parallels.

Electrophysiology of the Elasmobranch Stomach
Science, 1959A 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.

The Acoustical Biology of Elasmobranchs
Environmental Biology of Fishes, 2001A report on the auditory capabilities and their associated functions of elasmobranch fishes along with a brief review of the physics of underwater sound as it relates to hearing by fishes is provided. The inner ears of elasmobranchs possess structures that are no different from other fishes, except for an enlarged macula neglecta, which is unique among

This article presents a current assessment of elasmobranch auditory biology and an evaluation of future directions for research. Excellent review articles have recently detailed the pre-1975 development of this field (Popper and Fay 1977, Myrberg 1978), so I will not emphasize that work.

Prey detection mechanism of elasmobranchs
Biosystems, 2007Elasmobranchs can detect a little amount of electric fields and they have characteristic approach strategies to find an electric dipole source generated by prey or conspecifics. They appear to align the body at a constant angle with the current flow line of the electric field while swimming towards prey.
