The world's largest predator in the fish genus, the great white shark averages 15 feet in length but can reach lengths of 20 feet and weights of more than 5,000 pounds. Some reports have indicated the great white can grow to 26 feet and weigh as much as 7,300 pounds.
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 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.
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.
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.
