Occurrence of a Rare Squaloid Shark, Trigonognathus kabeyai, from the Hawaiian Islands

Abstract

The first occurrence of the rare viper shark, Trigonognathus kabeyai, from the central Pacific Ocean is reported. Morphometries are compared between this specimen and the type specimens from Japan, and this specimen differs from the types in only a few measurements. The poor preservation of this specimen precluded examination of internal anatomy.
