The biology of this endemic species is poorly known but it is reported to be common. Although it has a limited distribution in southwestern Australian coastal waters, it is not subjected to any significant fishing pressure due to its reef-dwelling habit and is of no commercial value to fisheries (although there is evidence that this catshark enters the marine aquarium trade).

Habitat and Ecology [top]

Habitat and Ecology: Aulohalaelurus labiosus common endemic inshore catshark on the temperate Western Australian continental shelf, found in shallow coastal habitats and on offshore reefs at a depth of least 4 m (Last and Stevens 1994).

The biology of A. labiosus is virtually unknown. Oviparous, and attains at least 67 cm total length (TL), with adult males mature at approximately 54 cm and attaining at least 61 cm (Last and Stevens 1994, W. White, unpubl. data). There is no published information on the age and growth or diets of this species.
Systems: Marine

Threats [top]

Major Threat(s): There is very little fishing pressure within the habitat range of this species in southwestern Australia and is also of little or no commercial value. There is evidence that this small, attractively spotted catshark enters the marine aquarium trade with several having been observed in aquarium retailers in Western Australia and it is possible that this may extend to elsewhere (Compagno, in prep., W. White, personal observation).

Conservation Actions [top]

Conservation Actions: Species composition data from fisheries and from collectors for the aquarium trade in southwestern Australia are required.
