The nervous shark (Carcharhinus cautus) is a species of requiem shark, and part of the family Carcharhinidae, so named because of its timid behavior in regard to humans. It is common in shallow, coastal waters off northern Australia, Papua New Guinea, and the Solomon Islands. A small brownish or grayish shark typically measuring 1.0–1.3 m (3.3–4.3 ft) long, this species has a short, blunt snout, oval eyes, and a relatively large second dorsal fin. The leading margins of most fins are finely edged with black, and the lower caudal fin lobe is black-tipped.

Small bony fishes are the main prey of the nervous shark, while crustaceans, molluscs, and snakes may also be eaten. It is viviparous, with the developing embryos nourished through a placental connection. The details of its life history seem to vary depending on latitude—for example, the timing of the breeding season and the length of the gestation period. Females produce litters of one to six young either annually or biennially. The harmless nervous shark is caught incidentally by coastal gillnet fisheries and perhaps also by line and trawl fisheries. The International Union for Conservation of Nature (IUCN) lacks sufficient data to assess the conservation status of this species except in Australian waters, where its population seems healthy and has been listed under Least Concern.
