Some decorator crabs are difficult to find because of the camouflage they accumulate over their body. The camouflage of algae, sponges, sea mosses, etc., is attached by hooks or grows directly on the exoskeleton and mimics the crab's environment, sometimes completely hiding the animal. This species has been referred in the past to the genus Naxia from which it differs in the absence of intercalated spine and having cylindrical propodi on the walking legs.
Subtidal to 71 m depth.
Southern temperate oceans, including south-eastern Australia.
Not harmful but a nip from large claws could be painful
