Hitting over 50 feet long, this was the largest shark of all time, and these guys used to hunt whales. Picture it this way: our biggest and baddest shark now, the Great White, is merely the size of this monster’s penis.

They used to rip off the tails and fins of prehistoric whales and let them flounder, while they enjoyed their meals. Lucky for us, they died off 2.6 Million years ago, right around the time humans began to evolve into who we are now.
