Hermit crabs are crustaceans that are adapted to live in empty shells. They have a long soft abdomen which is curved to fit into the spiral of the shell and their two claws are often different sizes.The shell protects the hermit crab from predators. The crabs carry their shell around and it acts as a 'portable burrow' but they can easily move out of their old shell and into a new one. It is very important that the shell fits well, If it is too small it will not protect them and if it is too large they waste energy carrying it around.

Before moving out of their old shell and into a new one a hermit crab spends a long time investigating the new shell and comparing it to their old one. They might turn the shell over several times and run their claws over the outside of the shell to check that it is not damaged. They then insert their claws into the shell to gauge how much space is inside it. Even after they have moved into the new shell they often investigate their old shell one last time before finally deciding which one to occupy.Sea anemones often attach themselves to the shell and give added protection with their stinging tentacles - when the crab changes its shell it prises off the anemones and puts them on the new shell.
