Identification

A huge striped shark with a broad, bluntly rounded snout, long upper labial furrows, a big mouth with large, saw-edged, cockscomb-shaped teeth, spiracles, and low caudal keels. Colour grey above with vertical black to dark grey bars and spots, bold in young but fading in adults; white below.

Size:

To 5.5 m and possibly 7.4 m TL.

Range

East coast, Cape St. Francis to Mozambique; circumtropical.

 

Habitat

Coastal and well offshore, surfline to 140 m depth.

Biology

Common off Natal, a summer visitor to the eastern Cape. Bears 10 to 82 young. The most opportunistic feeder amongst sharks, eats other sharks, rays, bony fish, birds, pinnipeds, small cetaceans, turtles, sea snakes, lobsters, crabs, cuttlefish, and mammalian carrion, and swallows a wide variety of inedible garbage.

Human Impact

Potentially dangerous; a few attacks on people off Natal are attributable to this species. Caught by sports anglers and the Natal shark nets.
