Megatooth Sharks Grew to Larger Sizes in Cooler Environments than in Warmer Waters

Otodus megalodon is commonly portrayed as a gigantic, monstrous shark in novels and films, such as the 2018 sci-fi thriller "The Meg." In reality, this species is only known from teeth and vertebrae in the fossil record, although it is generally accepted scientifically that the species was indeed quite gigantic, growing to at least 50 feet (15 meters) and possibly as much as 65 feet (20 meters). The new study re-examined published records of geographic occurrences of Megalodon teeth along with their estimated total body lengths.
