Also known as a ratfish, spookfish, and ghost sharks, chimaeras are believed to be some of the oldest fish in existence. They live in extremely dark and deep water so running into one of these monsters is sure to give you nightmares. Just look at that face!

While most of the creatures on our list are rather large, these guys are tiny. Like…microscopic! What’s freaky about them is how durable they are…kind of like Twinkies. They can survive in almost any temperature and can survive without water for more than a decade!
