Tuesday Crustie: Crab-like

Allopetrolisthes punctatus looks like a crab, but belongs to a different group (Anomura) than the crabs that most people think of (Brachyura). Count the legs; this one has 10, but the last two are very small and tucked away, which is characteristic of anomuran crabs but not brachyuran crabs.
