Rough skin dogfish

From Openwaterpedia
(Redirected from Dogfish shark)

noun - The rough skin dogfish or prickly dogfish is a poorly known species of dogfish shark. Reaching a length of 75 cm (30 in), this brown to gray shark has a very thick body with a prominent "humpback" and extremely rough skin. It is further characterized by two enormous, sail-like dorsal fins placed relatively close together. Both dorsal fins have a spine embedded mostly within the fleshy leading portion of the fin; the first dorsal spine is tilted forward.

Found near the sea floor over outer continental and insular shelves and upper slopes, the prickly dogfish shark is thought to be a slow-moving predator of small benthic organisms. It is aplacental viviparous, with females giving birth to litters of around seven pups. This species is an uncommon bycatch of bottom trawls, though there is presently insufficient information for the International Union for Conservation of Nature (IUCN) to assess its conservation status.
