Megalodon (scientific name: Carcharocles megalodon), also known as Megalodon, is an extinct prehistoric shark of the genus Ear Shark, and the largest known marine predator with the largest bite force. Mature adult Megalodon average length of 16 meters, the longest or up to 25 meters; weight between 30'000~65'000kg. Its body is torpedo-shaped, with a conical nose, huge pectoral and dorsal fins, and a powerful crescent-shaped tail. This species possesses a strong bite force, and its jaw force is strong enough to crush a small car.

It is an extinct giant shark, considered the largest shark in history and possibly the largest fish. Living during the Early Miocene to Pliocene period, approximately 23 to 2.6 million years ago. Fossil teeth are the main evidence for the existence of this ancient predator, and these teeth can grow up to 18 centimeters long, more than three times the size of modern great white shark teeth. It has a huge body size and a very strong biting force, making it the strongest known animal. The teeth are similar to modern great white sharks, with triangular, serrated edges and symmetry, but larger, thicker, more evenly spaced serrations, and a darker, V-shaped area near the root of the teeth.
