Great White: Great White Shark
built 277 days ago
Great White Sharks are large, rare, warm-blooded apex marine predators. It is estimated that they mature at 12-18 years for females and 8-10 years for males. Maximum length is 6.4 metres, though specimens of up to 7 metres may exist. Great White Sharks reproduce only one every two to three years and produce between two and ten pups per litter. Further information and references on the biology and ecology of the species can be found in the White Shark Recovery Plan.

Great White Sharks are cautious hunters. Despite their ferocious reputation, these sharks will often stalk their prey silently and without notice before taking a preliminary bite to test their prey. After inflicting an initial wound, the shark will often retreat and wait for the victim to weaken or die. Often humans who are attacked, by mistaken identity in most cases, will survive because this bite and retreat tactic allows them to reach help before the shark returns.

The Great White Shark has about 3000 teeth, which are arranged in rows. For grabbing and cutting prey, they use the first two rows of teeth. The teeth in the last two rows rotate into place when the front teeth are worn out, broken or fall out. The teeth are shaped like a triangle with serrations on the edges.

Hearing: Great White Sharks have two internal ears, known as the [M]acula neglecta. These are very sensitive and can detect sounds in the range of 10 HZ to 800 HZ (Human hearing is in the range of 25-16,000 HZ). Sound pressure waves are channeled down tiny cartilaginous tubes in the top of the skull to the inner ears.
