White-spotted hermit crab

Dardanus megistos


About 10-15 cm large, this species has an asymmetrical abdomen that is concealed in a scavenged mollusc shell carried around.


Native to the reefs in the Indo-Pacific region from Africa to the South China Sea.


As hermit crabs grow, they require larger shells. Since suitable intact gastropod shells are sometimes a limited resource, vigorous competition often occurs among hermit crabs for shells.
