The great white shark, Carcharodon carcharias, also known as white pointer, white shark, or white death, is an exceptionally large lamniform shark found in coastal surface waters in all major oceans. Reaching lengths of about 6 m (20 ft) and weighing up to 2,250 kg (5,000 lb), the great white shark is the world's largest known predatory fish. It is the only surviving species of its genus, Carcharodon.

The Great White is between 12-16 feet long, and can grow up to 19-21 feet. There is another main reason why the Great White is the most feared fish for humans.

Great White Sharks are a very large species of shark. They are streamlined swimmers, and have a torpedo-shaped body with a pointed snout.

They have about 3000 teeth, arranged in several rows. The first two rows of teeth are used for grabbing and cutting prey, while the teeth in the last rows rotate into place when front teeth are broken, worn down, or fall out. The teeth are triangularly shaped with serrations on the edges.

The back of the shark is a dull grey colour and the underside is coloured white. They have three main fins: the dorsal (on back) and two pectoral fins (on the sides). The tail is crescent shaped. There are five gill slits on Great White Sharks

The Great White reaches maturity about 9 years after it's birth. The growth of The Great White shark is about 25-30 cm per year. The White Shark has litters of about 7-9 pups. The females only reproduce twice in her whole life.

Great White Sharks live in all coastal temperate waters, and have been known to occasionally make dives into the deep water of open oceans. They can be found in water as shallow as three feet deep, and as deep as 1280metres. They can be found on the following coastlines: California to Alaska, the east coast of the USA, most of the Gulf coast, Hawaii, most of South America, South Africa, Australia (except the north coast), New Zealand, Mediterranean Sea, West Africa to Scandinavia, Japan, and the eastern coastline of China to Russia.

大白鯊，口中都有成排的利齒。只要前排的牙齒因進食脫落，後方的牙齒便會補上。新的牙齒比舊的牙齒更大更耐用。而角鯊和棘角鯊等鯊魚則會更換整排牙齒。鯊魚的牙齒呈鋸齒狀，如此一來，鯊魚不但能僅僅咬住獵物，也能有效的將牠們鋸碎。
大白鯊的上下顎並未和頭部緊密相連。

由於大白鯊的上下顎並未和頭部緊密相連，牠可以將上顎向上和向前延伸吞下獵物，有時甚至能將獵物一口吞下。
成為鯊魚主食的海豹鯊魚大多以腐肉為生。
