japanese spider crabJust in case you didn't think crabs were creepy enough, this time-lapse video of a giant Japanese spider crab molting should seal the deal for you. With a leg span of up to 12.5 feet and a weight that can exceed 40 pounds, this bad boy is considered the largest arthropod in the world.

But, its epic size doesn't stop it from shedding its skin every now and again. No sirree. And you know what it does with its shell after it slips out the backdoor? It chows down on it to recover valuable nutrients. Dinner and a show.
