Popularized by Hollywood monster movies, the Carcharocles megalodon, was the largest shark to have ever lived, according to the Smithsonian Institution. 

Scientists believe the largest megalodon reached up to 60 feet in length and weighed up to 50 tons. And as Andrews can attest — they possessed teeth the size of a human hand.

According to the Smithsonian, megalodon lived between 23 and 3.6 million years ago across all of Earth's oceans.
