A New Eastern North Pacific Smoothhound Shark (Genus Mustelus, Family Triakidae) from the Gulf of California

From: Copeia | Date: December 15, 2005| Author: | Copyright information

A new Smoothhound shark, Mustelus hacat, is described from the eastern North Pacific. Four species of the genus Mustelus had been previously recognized in this area: M. californicus, M. henlei, M. lunulatus, and M. dorsalis. Mustelus hacat is described on the basis of 36 specimens caught in the Gulf of California. Among the Smoothhound sharks in the eastern North Pacific, M. hacat is distinguished mainly by having color uniform dark gray-brown above, white below, with conspicuously white tips and trailing edges of dorsal, pectoral, anal, and caudal fins; upper jaw teeth cuspidate and ...
