Roughskin catshark
The roughskin catshark is a species of catshark in the family Pentanchidae, the deepwater catsharks. This species is found near Australia and New Zealand. Its natural habitat is the open seas. This species belongs to a genus of poorly known deep-water catsharks.
This species was first described in 2008 by Ryohei Sasahara, Keiichi Sato & Kazuhiro Nakaya.
Very little is known of its biology. This species is known to occur in deep water off New Zealand, sporadic sites around Tasmania, and a small area of Western Australia. Some concern exists for this species, as its distribution includes some heavily fished areas. Deep-water demersal trawl fisheries are expanding in the region, and assuming its biology is like other deep-water shark species, it may not be sufficiently fecund to withstand the exploitation pressure.
