Broadfin Sawtail Catshark

About the Broadfin Sawtail Catshark

The broad fin sawtail catshark is a species of ground shark found off the coast of Japan, at depths of 150 – 540 m. Like all members of the catshark family, they’re bottom feeders, have elongated cat-like eyes, and two small dorsal fins set far back. They’re mostly nocturnal and often sleep in groups during the day. Their diet consists of bony fishes and bottom-dwelling crustacean and cephalopods.

They’re slender dark grey grey sharks with black saddles along their dorsal side. They lay eggs, two at a time. Pups are born about 13 cm long, become mature at 50-60 cm cm, and grow to a maximum length of 70.

Their name comes from their broad crest of dermal denticles, tooth-like scales, along their caudal fin.

There is not enough confirmation to assess their population health. Their conservation status is “Data Deficient.”
