Description

Habitat

Typically found in water with a depth of 0 to -4,981 meters (0 to -16,342 feet).[4]

Ecology: Little is known of this rare benthic hornshark. Recorded from the outer continental shelf and uppermost slope in 40 to 275 m , with most records below 100 m (unusual for the family in being recorded from relatively deep water ). At least one station that recorded this shark was on sand (Compagno 2001). Although eggcases have not been reported to date it is presumably oviparous . A hatchling and young individuals have been recorded from off southern Mozambique at 110 m (Compagno 2001).

Diet includes crabs (from the stomachs of two individuals) (Compagno 2001).[5].
