Do you know about leopard seals? They're one of the fiercest predators who live in Antarctica and its waters, that can reach sizes of up to 1,320 lbs! Their sharp teeth are used to shred their prey, mainly penguins (so sad!), and they can open their jaws incredibly wide.
Paul Nicklen, a photographer for National Geographic, came face to face with one of these seals and what happens is just...fascinating!
Check it out! (I should warn you not to, though, if you have a hard time with seeing nature take its course...meaning that you WILL see some little adorable penguins get killed :'( , this may not be for you.)
