Range Great white sharks live anywhere where water temperatures are between 54 degrees fahrenheit and 75 degrees fahrenheit. One of the densest populations is found in Dyer Island, South Africa. Great white sharks tend to be found in the presence of thick blubbery marine mammals such as seals and sea lions. Great white sharks are not just a coastal species. They have been found in the open ocean at depths down to 3,900 feet. Recents studies have shown a Great White migrate from South Africa to Australia in 9 months. Scientist are not sure why they make this 12,000 mile journey but it could be because of seasonal mating or feeding. Body Great White sharks have a long torpedo-like body with a conical snout.
