Sombre Catshark

About the Sombre Catshark

The Sombre Catshark is a species of ground shark found in northwestern Australia. Like all members of the catshark shark family, they’re bottom feeders, have elongated cat-like eyes, and two small dorsal fins set far back. They’re mostly nocturnal. They often sleep in groups during the day and do their hunting at night.

Their reproductive method and average litter size are unknown. The maximum length is also unknown as the species was described from a single specimen, which was an immature male measuring 45 cm/1.49 ft.

There is not enough confirmation to assess their population health. Their conservation status is “Data Deficient.” No deepwater fisheries currently operate at the depths where this species was caught (900-1,000 m). However, the full extent of the species’ occurrence is unknown and so any interactions with fisheries is also unknown. This species is not known to be utilized. There are no species-specific conservation actions in place. Further specimens are required.
