Medaeops is a genus of crabs in the family Xanthidae, containing the following species: [1]
Xanthidae is a family of crabs known as gorilla crabs, mud crabs, pebble crabs or rubble crabs. Xanthid crabs are often brightly coloured and are highly poisonous, containing toxins which are not destroyed by cooking and for which no antidote is known. The toxins are similar to the tetrodotoxin and saxitoxin produced by puffer fish, and may be produced by bacteria in the genus Vibrio living in symbiosis with the crabs, mostly V. alginolyticus and V. parahaemolyticus.
Mictyris is a genus of brightly coloured crabs, placed in its own taxonomical family, the Mictyridae. It inhabits the central Indo-West Pacific region. These crabs congregate on mud flats or beaches in groups of a few thousand, and filter sand or mud for microscopic organisms. They congregate during low tide, and bury themselves in the sand during high tide or whenever they are threatened. This is done in wet sand, and they dig in a corkscrew pattern, leaving many small round pellets of sand behind them.
Cronius is a genus of crabs containing the two species Cronius ruber and Cronius tumidulus.
Discoplax is a genus of terrestrial crabs. It is very closely related to the genus Cardisoma.
The Gecarcinidae, the land crabs, are a family of true crabs that are adapted for terrestrial existence. Similar to all other crabs, land crabs possess a series of gills. In addition, the part of the carapace covering the gills is inflated and equipped with blood vessels. These organs extract oxygen from the air, analogous to the vertebrate lungs. Adult land crabs are terrestrial, but visit the sea periodically, where they breed and their larvae develop. Land crabs are tropical omnivores which sometimes cause considerable damage to crops. Most land crabs have one of their claws larger than the other.
Discoplax rotunda is a species of land crab in the genus Discoplax found in the Pacific Ocean.
Pseudozioidea is a superfamily of crabs, formerly treated in the Eriphioidea, Carpilioidea, Xanthoidea, Pilumnoidea and Goneplacoidea. A number of fossils from the Eocene onwards are known from the family Pseudoziidae. Eleven genera are recognised in three families:
Karstarma is a genus of karst-dwelling crabs formerly included in Sesarmoides.
Hypocolpus is a genus of crabs in the family Xanthidae, containing the following species:
Medaeus is a genus of crabs in the family Xanthidae, containing the following species:
Gaillardiellus is a genus of crabs in the family Xanthidae, containing the following species:
Meractaea is a genus of crabs in the family Xanthidae, containing the following species:
Alainodaeus is a genus of crabs in the family Xanthidae, containing the following species:
Demania is a genus of crabs in the family Xanthidae, containing the following species:
Euryxanthops is a genus of crabs in the family Xanthidae. It was originally established in 1983 by Garth & Kim to contain three species of deep-water crabs from Japan and the Philippines - Euryxanthops dorsiconvexus, Euryxanthops flexidentatus and Euryxanthops orientalis. Since then, several more species of this genus have been identified and described, and Euryxanthops currently contains:
Liagore is a genus of crabs in the family Xanthidae, native to Australia, containing the following species:
Lophozozymus is a genus of crabs in the family Xanthidae, containing the following species:
Heikeopsis is a genus of crabs containing two species, Heikeopsis japonica and Heikeopsis arachnoides. The genus was originally described under the name "Heikea" by Lipke Holthuis and Raymond B. Manning in 1990, but was later revealed to be a junior homonym of the gastropod genus Heikea, erected by Orvar Isberg in 1934.
Mathildellidae is family of crabs belonging to the superfamily Goneplacoidea, containing the following genera:
Euryxanthops chiltoni is a species of crab found in the New Zealand Exclusive Economic Zone. It was first described by Colin McLay and Peter Ng in a 2007 paper, along with Medaeops serenei.
