Watch hermit crabs form a line from biggest to smallest to trade shells

This is a clip from an episode of BBC's Life Story and it shows how orderly (and also completely chaotic) hermit crabs can be when it comes to trading homes. They all meet up in front of a shell, line themselves up from biggest to smallest and then trade shells with each other by jumping from one to the next. » 3/04/15 10:30pm 3/04/15 10:30pm

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. » 11/21/13 7:52pm 11/21/13 7:52pm
