Giant Hermit Crab

Lucky hermit crabs with plentiful resources can live for decades and grow to tremendous sizes, often with magical help. Too large for most natural shells, giant hermit crabs use a variety of debris instead, including wagons, boats, treasure chests, and even abandoned pieces of giant armor.

Crabs are scavenging crustaceans known for their hard shells and iconic sideways gait. They use their claws to defend themselves, hunt, and fight other crabs for territory. When confronted with threats from outside their species, most crabs prefer to flee, but when retreat isn't possible, they clamp on to their foes as tightly as they can.

Hermit crabs have hard exoskeletons like other crabs, but with much weaker abdomens. They find and “wear” shells as homes and protection, getting around with their front legs and claws. Surprisingly fierce, hermit crabs fight for new shells as they grow bigger, using an assortment of hollow alternatives as substitutes when shells of the right size can't be found.

Crabs can be found along all of the world's coastlines, from relatively small creatures like the king crab or the coconut crab, to truly oversized monsters like the great reef crab, shark-eating crab, or the lumbering shipwrecker crab.

Hermit crabs often form symbiotic relationships with sea anemones, attaching them to their shells. The anemones help protect the crabs while feasting on leftovers from the crabs' meals. When hermit crabs change shells, they often take their anemone partners with them to continue their lifelong adventure.
