These two have been around for a long time, like, over 200 million years! That's even before trees were like, a thing. And, despite their tough exterior, they're actually pretty sensitive creatures. I mean, they have special valves in their ears and eyes that help them keeps things out when they're underwater, like a built-in scuba gear!
Crocodiles and alligators are also like the ultimate predators, with some species growing up to 23 feet long and weighing over 1,000 pounds. That's like a small car! But, despite their fearsome reputation, they're actually pretty shy creatures and will usually avoid humans. Unless, of course, they're feeling hangry, then you might be in trouble!
