The hairy stone crab (Lomis hirta) is a crab-like crustacean that lives in the littoral zone of southern Australia from Bunbury, Western Australia, to the Bass Strait.[2] It is the only species in its family. It is 1.5–2.5 cm (0.6–1.0 in) wide,[2] slow-moving, and covered in brown hair which camouflages it against the rocks upon which it lives.[3]

Some controversy exists about the relationship between L. hirta and the other anomuran families. Candidates for its closest relatives have included hermit crabs,[4] specifically king crabs,[5] and Aegla.[6][7] It is clear, however, that Lomis represents a separate case of carcinisation.[8]
