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.
Sharks are fish, but unlike other fish, their skeletons are made of cartilage rather than bone, and instead of smooth, flat scales they have sharp, tooth-like scales called denticles. Scientists believe that sharks are 200 million years older than the oldest dinosaur, meaning they have been around f
An amazing fact about sharks is that the skins of females are much thicker than that of males. This is because male sharks tend to bite the females during mating. In its lifetime, a shark can go through about 30,000 teeth.
Some fun shark facts include that they have no bones, they have skin like sandpaper, have extraordinary sensory skills and teeth that are constantly being replaced. Most sharks never stop swimming and some species give birth to live young, called pups.
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 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.
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.
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.
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.
