Living in an abandoned shell, Hermit Crab is a familiar sight along the coast. When Hermit Crab is young, She lives in tidal pools, inside a Winkle Shell. When She becomes an adult, Hermit Crab will move offshore away from the pounding surf and live in a shell of a Sea Snail.
Hermit Crab often shares the outside of Her shell with a Sea Anemone. In addition, Hermit Crab will allow other Crustaceans and small Worms to live inside Her shell. In return, these animals protect Hermit Crab from Her major predators, Octopus and Squid.
Hermit Crab teaches sharing with others. However, sometimes Hermit Crab will pull out another Crab from their shell and use the stolen shell. Remember to be considerate of your own family members.
