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.

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.

The postorbital palatoquadrate articulation in elasmobranchs
Journal of Morphology, 2008AbstractAlthough modern hexanchiforms are the only extant elasmobranchs with a postorbital articulation, according to most morphological and molecular cladistic analyses they are not basal, suggesting that Huxley (1876Proc Zool Soc 1876;24–59) correctly identified this articulation as “an altogether secondary connection.” A postorbital articulation is ...

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.
