This primarily nocturnal shark usually forages for food at night, and rests under reef overhangs and caves during the day in small groups, often piled across or on top of one another (2) (4). At night, the species feeds on a variety of bottom-dwelling lobsters, crabs, octopus and sea urchins, as well as small fishes, usually returning to the same area each morning to rest (2) (4).
The tawny nurse shark is ovoviviparous, with females giving birth to up to eight live young that have hatched within the uterus (4).
