Great white sharks can swim at speeds of 25 km/h (16 mph) [9] for short bursts and to depths of 1,200 m (3,900 ft). [10] The great white shark is arguably the world's largest-known extant macropredatory fish, and is one of the primary predators of marine mammals, such as pinnipeds and dolphins.
Mackerel sharks, also called white sharks, are large, fast-swimming sharks, found in oceans worldwide. They include the great white, the mako, porbeagle shark, and salmon shark. Mackerel sharks have pointed snouts, spindle-shaped bodies, and gigantic gill openings. The first dorsal fin is large, high, stiff and angular or somewhat rounded.
Great whites are known to do this on occasion, referred to as a "test bite", in which the great white is trying to identify what is being bitten.

The longest a great white was held in captivity was at the Monterey Bay Aquarium, in September 2004. A young female was kept in an outdoor tank for 198 days before releasing her back into the wild. In the following years, the Monterey Bay Aquarium hosted five more juvenile white sharks for temporary stays before ending its program in 2011. [3]
A commonly referred to transition is the evolution of Isurus hastalis, the extinct giant mako, into the great white shark, Carcharodon carcharias. There exist teeth that are believed to represent the transition between the two species. These teeth, from Carcharodon sp. are characterised by the wider, flatter crowns of the extinct giant mako ...
