Longfin sawtail catshark

The longfin sawtail catshark (Galeus cadenati) is a rare, little-known species of deepwater catshark., part of the family Pentanchidae. Once thought to be a subspecies of the roughtail catshark (G. arae) along with the Antilles catshark (G. antillensis), it inhabits deep water off the Caribbean coasts of Panama and Colombia. This slim-bodied species has a marbled dorsal color pattern and a prominent crest of enlarged dermal denticles along the dorsal edge of its caudal fin. It can be distinguished from similar species by its relatively longer anal fin and small adult length of under 35 cm (14 in). The longfin sawtail catshark is oviparous.
