Habitat and Ecology
Bathydemersal deepwater species found on the upper continental to insular slopes at depths of 358–895 m (Compagno et al. 2005). Attains at least 64 cm total length (TL) (Compagno et al. 2005). Males are immature at 56 cm TL and females are immature at 59–64 cm TL (Compagno et al. 2005). Reproduction is presumably oviparous. Little else is known of the biology of the species.

Justification
The Salamander Catshark (Parmaturus pilosus) is a little known catshark known from Japan and the East China Sea on the upper to middle continental slope from 358–895 m. Attains at least 64 cm TL. A potential bycatch of trawl fisheries operating within its range, but no details are available. Given the lack of information on the species’ biology and threats to it, the Salamander Catshark is assessed as Data Deficient and should be reassessed as more data become available.

Management

Conservation Actions

Learn more about this article

Conservation Actions
No conservation measures are in place at this time. Like many deepwater species, more information on the biology and ecology of the species and its importance in fisheries is required to assess the status and future conservation needs. Where taken, catches should be closely monitored to ensure that the current population is not adversely affected.

The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and management of all chondrichthyan species in the region.
