The Carcharodon Megalodon Super-Shark


The Carcharodon megalodon super-shark swam in the oceans more than a million-and-a-half years ago. It grew up to 16m (52ft) in length and weighed in at 100 tonnes - 30 times heavier than the largest great white - and must have been one of the most formidable carnivores to have existed. "Pound for pound, your common house cat can bite down harder, " explained Dr Stephen Wroe of the University of New South Wales, Australia. "But the sheer size of the animal means that in absolute terms, it tops the scales."


By looking at the distribution of stress and strain on the sharks' jaws, researchers found that the largest great whites have a bite force of up to 1.8 tonnes, three times the biting force of an African lion and 20 times harder than a human bites. Megalodon, though, is more impressive. It is estimated to bite down with a force of between 10.8 to 18.2 tonnes. The team said biting with such force was quite a feat given that the jaws of these ancient creatures were made of flexible cartilage. In contrast to most other fish, sharks' skeletons are made up entirely of cartilage. Scientists think that cartilage, being a much lighter material than bone, is one adaptation that allows sharks to swim without the aid of a swim bladder.
