Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A large, bulky nurse shark with a small mouth and small comb-like teeth, and with angular fins (Ref. 5578). Caudal fin shorter, much less than half the length of body; no ridges on side of the body; pectoral fins falcate (Ref. 6871). Brown dorsally, paler ventrally (Ref. 391); fins slightly dusky (Ref. 9999). Spiracles much smaller than eye (Ref. 9999).

Biology     Glossary (e.g. epibenthic)

Found on continental and insular shelves, from the intertidal down to at least 70 m (Ref. 247). Occurs on or near the bottom in lagoons or along the outer edges of coral and rocky reefs, sandy areas near reefs and off sandy beaches (Ref. 247, 43278). Primarily nocturnal, but may be active during the day (Ref. 247). Prefers crevices and caves on reefs but may be found hiding in more exposed areas (Ref. 247). Forms resting aggregations, and often seen piled across or on top of one another (Ref. 247). Feeds on a wide variety of bottom invertebrates, small fishes (Ref. 247), including cephalopods, crustaceans and sea urchins (Ref. 37816), corals (Ref. 68964). Docile and known to allow itself to be touched, but a few non-fatal attacks have been recorded (Ref. 247). Ovoviviparous (Ref. 43278). 4 or more young are born per litter (Ref. 37816). Survives in captivity (Ref. 247). Marketed fresh and dried-salted; fins dried for the oriental sharkfin trade; liver processed for vitamins and oil; offal processed for fishmeal; hide potentially valuable for leather (Ref. 247).

IUCN Red List Status (Ref. 115185)

  Vulnerable (VU) (A2abcd+3cd+4abcd)

Threat to humans
