Megalodons were enormous, three times longer than a great white. An adult megalodon's teeth could grow as large as nearly 7 inches. "The megalodon shark was the apex predator in the water ...
Megalodon teeth can measure over 180 millimeters (7.1 in) in slant height (diagonal length) and are the largest of any known shark species, [29]: 33 implying it was the largest of all macropredatory sharks. [35] In 1989, a nearly complete set of megalodon teeth was discovered in Saitama, Japan.
It exceeded 3 m (9.8 ft) in length, and would have weighed in at around 200 kg (440 lb), much larger than any other known mustelid, living or extinct. [157] [158] [159] There were other giant otters, like Siamogale, at around 50 kg (110 lb) [160] and Megalenhydris, which was larger than a modern-day giant river otter. [161]

The megalodon, a huge shark that was the scourge of the ancient oceans and is a star in modern movie theaters, is named for its "large tooth" - and for good reason. Its serrated teeth - up to ...
This specimen had teeth measuring up to 9.87 cm (3.89 in) in diagonal length, and vertebral centra around 1.10 cm (0.43 in) in diameter. [5] Smaller individuals were about 6–6.6 metres (20–22 ft) long, still larger than the avarage extant great white shark. [9] [5] Tooth of O. angustidens
