Habitat and Ecology
A rare shark known only from two specimens taken on insular slopes, on or near the bottom at 572 to 1,482 m depth. The holotype is a 51.4 cm TL gravid female (Hawaiian specimen). The other known specimen is a 10.5 cm TL juvenile (Sulawesi specimen).

Apristurus species are relatively small, sluggish sharks that live on or near the bottom on the upper continental slope. Diet includes crustaceans (penaeid shrimps, euphausiids), squids and small fishes. Where known reproduction is oviparous with one egg per oviduct. Egg cases are usually thick-walled and about 5 to 6.8 cm long and 2.5 to 2.9 cm wide. The anterior end of the case has a long weak fibrous thread on each corner. The posterior end usually has two small processes, each with a long coiled tendril. As in shallow water scyliorhinids the coiled tendrils are probably used to attach the egg cases to hard substrates and/or biogenic structures as they are laid.
