Species Feature: Carrier crabs

Carrier crabs do what they say on the tin

I was in debate about whether to put carrier crabs in the post with my favorite decorator crabs, but thought they deserved a bit more highlighting.  Carrier crabs have specially modified back legs that hook and hold another ‘critter’ onto their back for protection.  Most of the time they carry urchins or jellyfish but I’ve seen video of them carrying larger nudibranch as well.  My favorite though has to be the crab carrying the banana peel (pic 3) :)
