One of the hermit crabs in my tank just pulled itself out of its shell, and walked around the tank. It climbed onto another crab, went for a ride for bit, then crossed the front of the tank before scuttling back to where it started and just hopped back into its original shell.
Weirdest thing I think I've seen in a while.
Ugly little crab as well... I did take some pictures, but I kind of felt dirty while doing so.
