Cn-270 CLOAK ANEMONE, Calliactis tricolor
They are a bizarre, reddish-pink sea anemone that lives on shells inhabited by hermit crabs. A fascinating example of symbiosis. The anemone’s nematocysts protect the hermit crab from predators. The crab provides the anemone with food and mobility. Flat clawed hermits (Ar-1420) often fight over anemones and steal them from one another. Size 1-3 cm across base.
