Seriously, even if spiders give you the heebie-jeebies, you need to watch this. With a little bit of audio editing, a tarantula shedding its exoskeleton becomes cute—even if it's still a bit creepy.
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.
Every so often, the killer whales that live around Antarctica will drop everything they're doing and swim three thousand miles due north. It's an extreme journey, but the end result is the whale equivalent of a day at the spa.
