Great White Shark

The great white shark, Carcharodon carcharias, also known as great white, white pointer, white shark, or white death, is a large lamniform shark found in coastal surface waters in all major oceans. The great white shark is very well known for its size, with the largest individuals known to have approached or exceeded 6 metres (20 ft) in length and 2,24 tons (4,938 lb) in weight. It reaches maturity at around 15 years of age and can have a life span of over 30 years. The great white shark is arguably the world's largest known extant macropredatory fish. It is the only surviving species of its genus, Carcharodon. The great white  is C. megalodon's closest living relative.

Food
Great whites eat seals, porpoises, other sharks, and whale carcasses. A great white was reported to tear another great white in half at Queensland, Australia.

Appearance & color
Great whites display countershading, having a white underside and a grey dorsal area (sometimes in a brown or blue shade) that gives an overall "mottled" appearance. The coloration makes it difficult for prey to spot the shark because it breaks up the shark's outline when seen from the side. From above, the darker shade blends with the sea and from below it exposes a minimal silhouette against the sunlight

Threats
Great white sharks are on the vulnerable species list because of shark finning, water pollution, and overfishing which causes scarce food for the shark. The orca is the only known living predator of the great white.
