Body Traits

They are one of the largest hermit crabs. They have large, oval, black eyes that stand up on stalks. The top of their claws are covered with spines. The legs and claws have red bands.


As they grow, hermit crabs abandon their shell and move into a larger one.


They will eat anything they can find (scavengers), including: worms, small sea creatures (invertebrates) and dead animals and plants.

Females carry eggs in a mass on their belly (abdomen) inside their protective shell. When the larvae hatch, they swim off to hide, feed and grow. As they grow, they shed (molt) their outer layer. Finally they will settle on the seabed as a young crab.
