This fellow has the typical single large claw and smaller opposite. This one's a lefty. He's somewhat territorial, and waves his arms when one of the fish swims by. The fish are all at least 5 times larger than he is, but that doesn't seem to enter into his brain.
'Wave his arms' isn't really accurate. He moves in spurts, first here, then there. Not a continuous motion, like The Royal Wave, but a quick position change -- like a ninja. He's pretty regular about it too, so he's been nicknamed the ninjatronic crab!
This isn't his best portrait, but I was lucky enough to capture his movement.
