Blue-leg/Blue-legged Hermit Crab Clibanarius tricolor

Hermit crabs have soft rear bodies and use a sea snail shell to protect their body from predators. They curl their rear body and hooked tail around the inside of the shell to walk about and move to a larger shell as they grow. The (Dwarf) Blue-leg/Blue-legged Hermit Crab, also called the Tri-coloured and Three-coloured, is native to the Caribbean.

As its name indicates, it has blue legs, with red banding and white tips. It is about 4cm (1.5 inches) long. Both claws are equal in size.
