Brown Catshark

Brown Catshark (Apristurus brunneus)

The brown catshark is a common sight at Southern Hydrate Ridge, and the species ranges from British Columbia down to the Baja California peninsula. These sharks live in the deep water on the outer continental shelf and the upper slope, and can usually be found near the seafloor in muddy or sandy areas. Brown catsharks have a long, slim body and a flat, rounded nose, and feed on many of the bottom-dwelling invertebrate species seen at SHR.
