Watch a crab climb out of its old shell like a mutant

Crabs are red alien water tarantulas who regenerate like mutants. Just look at this crab literally climb out of its old shell and toss away that used exoskeleton like it's a dirty pair of pants. So gross but so cool. I kind of wish I could shed skin like this. It'd probably be the most refreshing feeling ever.

Pointed out by a Reddit user, the molting action starts around the 45 second mark in the video. The whole process of shedding its old body takes hours (it's been shrunk down to a minute in the video). When you see the arms come out, you'll probably shriek.
