Hermit crabs from South Andamans

Hermit crabs, amazing variety of shells can be seen and even the hermit crabs too

These guys utilize shells of snails to protect their soft abdomen from predators. Not only abdomen but whole body is retracted inside the shell.

As the hermits grow in size, they change the shells, the abdomen is flexible enough to grip the shell on inner side. And they have amazing shells and even hermits themselves come in variety of colours.
