Distribution

Off Cape Hawke, NSW (ca. 32°13'S) to off Exmouth Gulf, WA; temperate, discontinuous (west Pacific, New Zealand and Gulf of Mexico and Atlantic).

Features

A Stout, dark black or brown dogfish. Short slender dorsal fin spines with only the tips protruding through the skin. First dorsal fin lobe-like and short, second dorsal fin triangular and taller. Paddle like pectoral fins and large, flat denticles giving Centroscymnus owstonii a smooth skinned appearance.

Feeding

Feeds on cephalopods and fish.

Biology

A viviparous (probably matrotrophic) species, with litters of 16-28 young. Males mature at 70 cm and females mature at 100 cm.

Fisheries

Once caught locally as bycatch for trawlers, catches are now restricted in Australia due to growing concerns for sustainability. Still occasionally caught by tuna longlines in Japanese waters.
