Megalodon

The biggest shark in the world.

We all know that this kind of predator or mammal is the "biggest" of them all. This kind of shark lives at Mariana Trench but study finds that Megalodon lives in the upper part of the water column over the Mariana Trench, it probably has no reason to hide in its depths. There is no food for it down there, and no other shark spieces are know to trive that deep.

In study, Megalodon was not the only biggest shark in the world, but one of the largest fish ever exist. It was estimated 15 to 18 meters in length, it is three times longer than Great white shark.

Stuides don't have a complete Megalodon skeleton , these figure are only based on animal's teeth which can reach 18 centimeters long. In fact, the word Megalodon simply means 'large tooth'.

Megalodon was an apex predator which means that it is at the top of its food chain, ate other predators and carnivorous. Great white shark is also a apex predator. This predator most likely to eat meat of whales and large fish. Studies have evidence of Megalodon's feeding habits in the form of fossilised whale bones.

Megalodon need to be able to open its mouth wide. It was estimated that its jaw would span 2.7 by 3.4 meters wide, easily big enough to swallow two adult people side-by-side. Humans have been measured with a bite force around 1.3 Newtons, while Great white shark have been predicted to bite down around 18.2 Newtons. Researchers have estimated that Megalodon had a bite of between 108.5 to 182.2 Newtons.

A female Megalodon may have been up to twice as the large of male Megalodon. Fossils of Megalodon have been found in every continent except for Antarctica. Researchers studied that there is no evidence of the Megalodon's continued existence in the shallow seas and any bite marks of the right size on the animals that would be their prey. Megalodons and dinosaurs did not coexist, they were separated by more than 40 million years.
