Habitat and Biology: Occurs in shallow waters from the inter-tidal zone to a depth of at least 70 m. Demersal on coral and rocky reefs, in lagoons and on sand flats. Feeds on a variety of bottom invertebrates, corals, and small fishes. Mainly nocturnal, often resting in caves or under overhangs by day. Ovoviviparous; number of young at least 4 per uterus.
Remarks: Four individuals of Nebrius ferrugineus (of length 134-226 cm in total length) were taken by hand line and longline by R.V. "Farumas" during the reef fish resources survey (Anderson and Ahmed, 1993, p.55). This is a tough and hardy shark that readily survives in captivity. N. concolor Ruppell, 1837 is a synonym.
