The largespine velvet dogfish, Centroscymnus cryptacanthus, is a sleeper shark of the family Dalatiidae, found on the lower continental slopes between latitudes 50° S and 54° S in the southeast Pacific Ocean from the Straits of Magellan, and the southwest Pacific from New Zealand, at depths of between 650 and 920 m. Its length is up to 68 cm.
The largespine velvet dogfish is a rare species, having dorsal fins with fairly prominent fin spines, moderately long snout, lanceolate upper teeth and bladelike lower teeth with short, oblique cusps. Its coloration is dark brown or blackish. It has a stocky body that tapers abruptly from the pectoral region, and moderately large tricuspidate and tricarinate lateral trunk denticles.
The largespine velvet dogfish is ovoviviparous.
