The Copper shark, Bronze whaler, or Narrowtooth shark (Carcharhinus brachyurus), is a large shark of the Carcharhinidae family, found in subtropical seas and oceans worldwide, except the eastern coast of North America and the northern Indian Ocean. Their length is up to about 3.5 metres and they can weight up to 300 kilogrammes.
The Bronze Whaler (its most common name) has a blunt broad snout, narrow bent cusps on the upper teeth, and no interdorsal ridge. They are gray to bronze in color on the back, and white below. The fins are similarly coloured except the pelvic fins, which have dusky tips, and the pectoral fins, which have dusky to black tips.
Bronze Whalers are often seen close inshore feeding on schooling fish, such as salmon, frequently within the surf zone but they are also found around offshore islands over deep water where they prey on squid as well as pelagic and bottom-dwelling fish.
The female will deliver between seven and twenty live pups. Males live for up to thirty years, and females for up to twenty five. It can be dangerous, particularly towards spearfishermen with recently speared fish, and also towards surfers as its prey is often found in the surf. It probably should not be classified as a 'maneater' due to the fact it probably doesn't target humans for food. It is often confused with the Dusky shark.
