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.

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 ...

Electroreception and the Ampullæ of Lorenzini in Elasmobranchs
Nature, 1964RECENT investigations of the sensitivity of certain groups of fishes to minute local potential changes have revealed the fact that all members of these groups possess specialized neuromasts in addition to their ordinary lateral-line organs. Whereas the ordinary organs are used as ‘distant touch’ receptors, responding to mechanical stimuli, several ...

Mineralization patterns in elasmobranch fish
Microscopy Research and Technique, 2002AbstractThis article reviews current findings on the organic matrix and the mineralization patterns in elasmobranchs, including an analysis of the role of the dental epithelial cells and the odontoblasts during odontogenesis. Our electron micrographs demonstrated that tubular vesicles limited by a unit membrane occupied the bulk of the elasmobranch ...
