Giant Monsters Roaming the Ocean
Seawater covers almost 70% of the earth’s surface. Early underwater predators were big and fast. Predators known as Megalodon roamed the depths of the sea millions of years ago. The great white shark has survived for more than 10 million years. It is the ultimate ocean’s predator today. Compared to Megalodon great white is a dwarf. With both sharks, cartilage is the balsa wood of the body, it is the flexible component in their body structure. They are held together with organic fibers. These organic fibers quickly decompose when a shark dies. This makes it difficult to find any full skeleton structures of sharks. In a shark skeleton there are only two components that survive. The first one is the teeth and the second is portions of the vertebrae. Megalodon teeth are easily recognized by the compression fractures.
