The speckled catshark, Halaelurus boesemani, is a catshark of the family Scyliorhinidae. It is found in the Gulf of Aden and off the coast of Somalia. It occurs at depths of between 37 and 250 m (120 and 820 ft). Its length is up to 48 cm.
Taxonomy
In the past, this species was thought to occur both in the western Indian Ocean and in the waters around Vietnam, the Philippines, Indonesia, and Western Australia, between latitudes 21° N and 26° S. However, two new species of Halaelurus have been described from these latter areas, and the speckled catshark is now thought to be restricted to the western Indian Ocean.[1]
Distribution and habitat
The speckled catshark is known from the Gulf of Aden, and off the coast of Somalia, with a separate population extending from Viet Nam and the Philippines, through Indonesia to Western Australia. It is a demersal species, living on continental shelves and insular shelves, with a depth range of between 37 and 250 m (120 and 820 ft).[2]
Status
The speckled catshark is poorly researched and the threats it faces are unclear. Fisheries in Somalia are largely unregulated, with foreign-owned vessels fishing ilegally. Artisanal fisheries are unlikely to target this species because of its small size, nevertheless it is vulnerable to being caught as bycatch in both trawling and netting operations. The International Union for Conservation of Nature considers that there is insufficient evidence to understand the conservation needs of this fish and have classified it as "data deficient".[1]
