Great white sharks move by swimming. These powerful predators attain top speeds of over 15 MPH, but are only able to sustain such speeds for brief bursts. Great whites swim constantly because they rely on a breathing technique called ram ventilation. They swim with their mouths slightly open to forc
Great white sharks have many tools with which to protect themselves, such as powerful jaws, unique scales and efficient eyes. The shark has, in fact, evolved to be both a fierce predator and a defensible fortress.
On average, great white sharks grow to be 15 feet long. Females typically reach a length of about 16 feet, while males reach a length of 11 to 13 feet.
Great white sharks are carnivores, meaning that they only eat meat. Food items on a mature great white shark's menu include sea lions, smaller whales, seals, sea turtles and otters, whereas younger sharks hunt smaller fish and rays. Great white sharks also eat carrion and even other sharks.
A 2013 study, detailed by Discovery, explains that great whites have a faster metabolism than previously thought and probably feed every few days. The study indicated that the amount of energy required by a great white was equivalent to eating a seal pup every three days.
The great white shark is endangered from years of being hunted by people for its fins and teeth. Great white sharks also get overhunted as trophies in sport fishing, according to the World Wildlife Fund. Another danger is accidental catching by commercial fisheries.
The great white shark has approximately 50 full teeth in its jaw, according to the Fox Shark Research Foundation. It has from 24 to 26 teeth in the upper jaw and 22 to 24 in the lower jaw.
The Canadian Shark Research Center reports that the largest accurately measured great white shark on record was a 20.3-foot-long female caught off Prince Edward Island in 1983. A great white shark said to have measured 21 feet was caught off Cuba in 1945, but this measurement has been disputed.
Because of its highly streamlined shape and powerful swimming muscles, a great white shark can swim up to 35 miles per hour in short bursts. In addition to its ability to swim in short bursts, a great white can also move at a steady cruising speed. Scientists recorded one great white that swam a tot
The great white shark is a fierce hunter that lives throughout much of the world's oceans, usually close to the coast. It can grow to be up to 20 feet long and may weigh up to 5,000 pounds. Its swimming speed reaches up to 15 miles per hour.
