context: Megalodon was one of the largest fish of all time. It is difficult to judge its size, but the study of the remains represented by a large number of teeth and fossil vertebrae shows that this shark was gigantic, reaching, according to various estimates, the maximum length of 15-16 meters and having a maximum weight of 30-35 to maybe 47 tons. Thus, megalodon was one of the largest aquatic predators in the history of our planet, along with pliosaurs, mosasaurs, dinosaurs, basilosaurs, deinosuchs, purusosaurs, kronosaurs and other animals that were larger than any modern predators, except for the sperm whale, which has similar sizes, but it occupies a slightly different ecological niche.
