Great White shark is a large shark which habits in most of the shores of all oceans which temperature is between 12 - 24 °C. The great white shark can length up to 6 metres and weight up to 1900 kilogrammes (although females are bigger than males), and its average life expectancy is 30 years. White sharks exist since the Mid-Mioceneepoch. They are carnivorous, and thanks to an extra sense (Ampullae of Lorenzini) they can detect the electromagnetic field emitted by animals when they move. Anyhow, sometimes they eat things that they cannot digest.
