The little sleeper shark is grey or brown in color, with a short, rounded snout, equal-sized dorsal fins, the first of which is closer to the pectorals than the pelvic fins, long ventral caudal lobe, and short keels on the base of the caudal fin.

It is a rare species found on the outer continental shelves and upper slopes. It probably feeds on deepwater bottom fishes and invertebrates. Reproduction is ovoviviparous, the length at birth of the pups is 21 to 28 cm. It is utilized as fishmeal and possibly as food fish.
