Justification:
Linuparus somniosus has been assessed as Least Concern. This species is widespread across the Indian and Pacific Oceans, and faces no major threat from fisheries. There is a single commercial fishery operation off Tanzania, while other fisheries operate at a small scale and are not directed at this species.

Geographic Range [top]

Range Description: This species is known from Kenya to Natal in South Africa (Holthuis 1991); the Sunda Shelf in the Straits of Malacca (Chan 1997, Ng 1992) and from Java and Indonesia (Wowor 1999).
Countries:
Native:
Comoros; Indonesia (Jawa, Sumatera); Kenya; Malaysia (Peninsular Malaysia); Mozambique; South Africa (KwaZulu-Natal); Tanzania, United Republic of; Thailand

Population [top]

Population: This species supports a commercial fishery in parts of its range, so is thought to be relatively common (Ivanov and Krylov 1980). In Indonesia, this species is not thought to be locally abundant, but occurs in sufficient quantities for it to appear in local markets (Wowor 1999).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species is found on rough substrates with sand and mud at a depth range of 216 - 375 m (Holthuis 1991)
Systems: Marine

Threats [top]

Major Threat(s): Apart from Tanzania, there is no known commercial fishery elsewhere within this species' range (Holthuis 1991). This species is not thought to be palatable and at present both the African fishery (excluding the commercial operation off Tanzania) and the Indonesian fishery are minor (Wowor 1999). The one commercial fishery off the coast of Tanzania may be causing local declines, although this is unlikely to be threatening the global population of this species.
