Teeth of Embryos in Lamniform Sharks (Chondrichthyes: Elasmobranchii)
Environmental Biology of Fishes, 2002The dentitions of lamniform sharks possess a unique heterodonty, the lamnoid tooth pattern. However, in embryos, there are ‘embryonic’ and ‘adult’ dentitions. The teeth in the embryonic dentition are peg-like and appear to be attached to the jaw in an acrodont fashion.

The mechanics of cutting and the form of shark teeth (Chondrichthyes, Elasmobranchii)
Zoomorphology, 1988A rich engineering literature exists that is applicable to many aspects of vertebrate jaw mechanics and has been referred to in many studies in this sector. But mechanical engineering technology has provided few theoretical bases that are directly helpful in the study of predator teeth. Hence, analyses of puncturing and slicing functions of these teeth

[Fine structure of the olfactory organ of elasmobranchs (Elasmobranchii)].
Zhurnal evoliutsionnoi biokhimii i fiziologii, 1976The structure of the receptor cells in the olfactory organ of the rays Raja clavata and Dasyatis pastinaca and spiny dogfish Squalus acanthias is similar to that of the olfactory cells in other Vertebrates, although their tops are invariably crowned by microvilli, not flagella.
