The hooktooth dogfish has a blunt, flattened snout, very large eyes, a relatively long distance from the eye to the first gill slit, small grooved dorsal spines, a first dorsal fin about halfway between the pectoral and pelvic fins, and a broad caudal fin. They are black with a maximum length of only 60 cm.
This shark is a little-known, yet common, shark that lives at depths between 110 and 560 m. They are ovoviviparous, with at least three pups per litter. They probably eat bony fish and invertebrates.
