インド洋から西太平洋にかけて生息している『アカオニガゼ』というウニの棘には毒があって刺さると激痛が走るそうな。
それを知ってなのかヘイケガニの仲間がこのウニを背負って武装を試みる事があるとの事…

Dorippe frascone
Dorippe frascone, the urchin crab or carrier crab, is a small species of crab in the family Dorippidae that was first described scientifically by J.F.W. Herbst, in 1785. It is found in the Red Sea and parts of the western and eastern Indian Ocean. It often has a symbiotic relationship with a long-spined sea urchin and carries one around on its carapace. Description The urchin crab is a brownish-pink colour and grows to a length of about 5 cm (2 in). 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 but those actually stick living creatures...
