Megalodon

Megalodons are gargantuan creatures with streamlined, muscular bodies stretching out nearly eighty feet from snout to tail. Black eyes, small in comparison to the rest of its body, stare out from a large head lined by five gill slits and culminating in a pointed snout and an incredibly large mouth filled with row after row of huge, sharpened teeth. The dorsal fin of the oversized shark is proportionate to its size, and rises up from the monstrosity's back, while two pectoral fins extend out from its sides. Large enough to cause serious damage on its own, the megalodon's tail is, by itself, easily the size of a regular shark.
