A Hermit crab uses an abandoned mollusk shell to protect its body. In addition, it carries a sea anemone on

the shell as a body guard. The stinging tentacles of the anemone deter the predators.

In return the anemone gains mobility, gets a larger feeding area and even the tasty left overs of the

crab’s meal! When the crab outgrows the shell, it moves into a larger shell. It takes its body guard along

with it, to its new home. It gives a warning tap so that the anemone loosens its grip on the old shell. The

crab lifts it onto its new shell with its claw.

Now the householder and its body guard are all set and ready for their next outing.
