Order: Decapoda – crayfish, crabs, lobsters, prawns, shrimp
White spotted hermit crab (Dardanus megistos) IUCN REDLIST: Not Evaluated
This species of hermit crab is commonly found beneath the water, they can vary in size but are distinguished by their white spots. Their left claw is larger than the other for defense against other crabs or predators. As they grow they change their shell upon availability. When a shell is available but too large for the hermit crab they will wait sometimes building up a que of hermit crabs that hold claws ranging from small to large until a crab of the right size arrives. The the que of hermit crabs will change shells moving up one and fitting themselves into the neighbors shell.
