Blobfish

Blobfish in its natural habitat looks like normal fish. It lives so deep underwater that it doesn't use a normal gas bladder to keep itself balanced. Instead, it has a spongy skin that is slightly less dense than water, which becomes damaged and bloated when fishermen bring it up too quickly. It's not really the ugliest fish. It has just experienced something worse than one of us being thrown into outer space. Between sea level and space, there's one atmospheric pressure of difference. Between sea level and 2000 feet underwater, their upper limit, there are 60 atmospheres of difference.
