Occurs over muddy bottoms, on the upper continental and insular slopes and outer shelves (Ref. 244). Feeds mainly on small bony fishes and crustaceans, with squid a lesser item in the diet (Ref. 244). One of the two smallest living sharks (Ref. 13566). Ovoviviparous (Ref. 50449), with 1 to 2 pups in a litter (Ref. 244).
