Dorippe frascone,Urchin Crab,Carrier Crab

Chinese name: 疣面关公蟹

The urchin crab is a brownish-pink colour and grows to a length of about 5 cm . It has long-stalked eyes, a rounded carapace and long, slender legs. It uses only the first two pairs of legs for locomotion because the third and fourth pairs are used to grip a sea urchin which it carries around on its back. It is similar in morphology to the jellyfish crab (Ethusa spp.) but is easily distinguished by the different invertebrate transported. It also resembles decorator crabs[2] but those actually stick living creatures such as sponges, hydroids and bryozoans, bits of algae and inert objects to their shells.
