Porcelain crabs are unique crustaceans known for their elegant and glossy appearance. They thrive in intertidal zones and possess a delicate nature, which allows them to camouflage effectively using their fuzzy exoskeleton. These crabs can be identified by their three pairs of walking legs and long antennae. When threatened, they may shed limbs as a survival tactic, or flatten against rocks to avoid capture. These charming creatures add beauty to the marine environment and are worth noticing when diving or exploring rockpools.
