14 Megalodon
The megalodon is an extinct species of shark which was about 59 feet (18 meters) long and hunted in the seas until about 1.5 million years ago. It was similar to today's great white shark-but three times longer and 20 times heavier.
Megalodon had more than 250 huge, razor-sharp teeth and its mouth was so huge that it could easily swallow a person. The fossils of its teeth were once thought to be the tongues of dragons or similar beasts.
Megalodon was in the same shark group as today's great white shark, mako shark, and porbeagle shark. All of these species of sharks are big, fast, fierce hunters-just like their prehistoric relative. Alright I know this animal is extinct but this maybe crazy but the megaladon is 20 METERS LONG that's bigger than a whale shark
Megalodons are like sharks but a billions times more scarier than Great White Sharks and just exactly like prehistoric dinosaurs.
