Megalodon is considered the strongest and largest marine animal.

It is theorized that this shark has a certain influence on the structure of ocean life. The appearance of this species also gives scientists a headache. The first theory is that the Megalodon shark is similar in structure to the great white, but larger in size. Accordingly, their jaws can be many times wider than that of great white sharks. Their fins are similar to great white sharks but larger.

Another theory is that the monster Megalodon bears a resemblance to the great shark (Rhincodon tupuѕ) or Cetorhinus mamimuѕ. Its caudal fin will be crescent-shaped, the second dorsal fin small, and has a small tail above the caudal peduncle. This structure is quite common in aquatic animals such as tuna, whales and many other sharks. This structure will help them reduce water resistance when swimming. The head will be different depending on its adaptation to the tube environment.

Based on the remaining fossils, scientists have estimated the size of this super shark. Accordingly, the Megalodon shark is likely to have a total size of up to 54 feet (about 16.5 m). This size is 3 times larger than the great white shark C. Carcharia.
