Description

The variegated catshark is a small, slender catshark of the family Scyliorhinidae reaching about 41 cm. The brown, streamlined body is covered with dark saddle blotches and speckles, a pattern that blends well against the bottom; the two small dorsal fins are set far back. The species is endemic to the continental slope of western and southern Australia, where it lives on soft bottoms of the deeper slope. On the bottom it hunts small crustaceans, molluscs and small fish at night. Like many catsharks it is oviparous: it lays eggs in horny egg capsules anchored to the bottom by tendrils. Because of its deeper habitat and low fishing pressure it is assessed as Least Concern (LC).
