Hairy stone crab

The hairy stone crab (Lomis hirta) is a crab-like anomuran 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 the family Lomisidae. 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]

Live specimen

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]

Notes

1. The name "Lomidae" may also be encountered, but is incorrect.^[1]
