Shark teeth have been used as weapons and tools for many centuries and today fossilized teeth of between 20 - 200 million years old are also sought-after keepsakes and jewellery items. The new teeth are larger than the ones they replace and some sharks even produce different shaped teeth as they grow older. great whites have up to 300 serrated, triangular teeth arranged in several rows and it is believed that they may use and lose more than 30 000 teeth during their lifetime. Baby sharks are born with sharp teeth and the ability to hunt right from the start. A great white shark is capable of eating sea lions whole. Sharks do not chew their food, they swallow it whole and if it is too big, they tear it into chunks with their special teeth.
Young great white sharks even eat leopard sharks.
Their main prey includes sea lions, seals, small toothed whales, and even sea turtles, and carrion. Sharks have a diverse, balanced diet ranging from fish to mammals. They are the great whites, tiger sharks, bull sharks and the oceanic white-tip. The chance of being killed by a shark is one in 300 million - the chance of being killed by aeroplane parts falling from the sky is one in 10 million! Of the more than 350 shark species, only four species are a threat to people IF we invade their territory.
I ronically, sharks have much more reason to fear people, seeing that up to 100 million sharks are killed by people every year.

They are merely curious and "sample biting" and have no intention to harm or kill humans, as human flesh is not on their menu! More than 70% of known victims of g reat white shark "bites" survive because the shark realizes it has made a mistake and doesn’t finish off the prey. They can even leave the water completely, breaching like whales when attacking prey from underneath. They are stately and streamlined torpedo-shaped swimmers with powerful tails that can propel them through the water at speeds of up to 15 miles (24 km) per hour. Their upper bodies are shades of slate-grey, blue and black to blend with the rocky coastal seafloor, but their underbellies are pure white. The biggest known great white ever caught was a mammoth 20 feet caught off Prince Edward Island in 1993. Their size and white bellies, as well as their awesomeness, lead to the name because they are not only big, they are a GREAT species! Great white sharks grow to an average of 15 feet (4,6 m) in length, though specimens exceeding 20 feet (6 m) and weighing up to 5,000 pounds (2,268 kg) have been recorded.
