About Xantho pilipes A.Milne-Edwards, 1867
This species, commonly called Risso's crab, has the accepted scientific name Xantho pilipes A.Milne-Edwards, 1867. Adult Risso's crabs are small, reaching 15–30 mm (0.59–1.18 in) in length. Their bodies have a marbled patterning and varied colouration that ranges across red, yellow, and brown. The species gets its specific epithet pilipes, meaning 'hairy legs', from the dense hairs that grow on the back of its legs. Xantho pilipes occurs in the Mediterranean Sea and the eastern Atlantic Ocean, and it is commonly found off the coasts of Great Britain and Ireland. This crab inhabits marine seawater at depths down to 100 m (330 ft), where it hides under rocks and within coarse gravel.
