Gulp. Just look at how ridiculous this thing looks. It’s a giant black sea slug known as a sea hare and it’s freaking monstrous. You don’t really hold it in your hand as much as the sea hare, which can grow up to over 3 feet long and weigh over 30 pounds, just swallows your entire arm. Brave Wilderness found the black sea hare in the tide pools off the coast of the Pacific Ocean in San Pedro, CA and described holding it as super slimy and unbelievably slippery.

The black sea hare gets its deep, dark color from its diet of algae and seaweed and gets it name from the two tentacles sticking out of its head that look like rabbit ears. Where it gets it comical size is probably some prehistoric alien energy source.
