<span class="mw-page-title-main">Xanthidae</span> Family of crabs

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.

<i>Gecarcoidea</i> Genus of terrestrial crabs

Gecarcoidea is a genus of terrestrial crabs. The crabs live in forests but must come to the coast to breed. When it is dry in the summer the crabs are inactive, but when it is the wet season they are ready to migrate.

<i>Mictyris</i> Genus of crabs

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.

<span class="mw-page-title-main">Xanthoidea</span> Superfamily of crabs

Xanthoidea is a superfamily of crabs, comprising seven families. Formerly, a number of other families were included in Xanthoidea, but many of these have since been removed to other superfamilies. These include Carpilioidea, Eriphioidea, Hexapodoidea, Pilumnoidea and Trapezioidea. Even in this reduced state, Xanthoidea remains one of the most species-rich superfamilies of crabs.

<i>Discoplax</i> Genus of crabs

Discoplax is a genus of terrestrial crabs. It is very closely related to the genera Cardisoma and Tuerkayana.

<span class="mw-page-title-main">Gecarcinidae</span> Family of crabs

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.

<span class="mw-page-title-main">Eubrachyura</span> Group of crabs

Eubrachyura is a group of decapod crustaceans comprising the more derived crabs. It is divided into two subsections, based on the position of the genital openings in the two sexes. In the Heterotremata, the openings are on the legs in the males, but on the sternum in females, while in the Thoracotremata, the openings are on the sternum in both sexes. This contrasts with the situation in other decapods, in which the genital openings are always on the legs. Heterotremata is the larger of the two groups, containing the species-rich superfamilies Xanthoidea and Pilumnoidea and all the freshwater crabs. The eubrachyura is well known for actively and constantly building its own burrows. The fossil record of the Eubrachyura extends back to the Cretaceous; the supposed Bathonian representative of the group, Hebertides jurassica, ultimately turned out to be Cenozoic in age.

<span class="mw-page-title-main">Pseudozioidea</span> Superfamily of crabs

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:

<span class="mw-page-title-main">Eriphioidea</span> Superfamily of crabs

Eriphioidea is a superfamily of crabs, containing the six families Dairoididae, Eriphiidae, Hypothalassiidae, Menippidae, Oziidae and Platyxanthidae. They are united by a number of characters, including a marked difference in size between the left and right claws, where the larger one has a crushing tooth, and the smaller one does not, and the relative breadth of the male abdomen.

<i>Euryxanthops</i> Genus of crabs

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:

<i>Pulcratis</i> Genus of crabs

Pulcratis is a genus of crabs in the family Xanthidae.

<i>Heikeopsis</i> Genus of crabs

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 determined to be a junior homonym of the gastropod genus Heikea, erected by Orvar Isberg in 1934.

Conleyus defodio is a species of crab, the only species in the genus Conleyus and the family Conleyidae. It lives in rubble beds in Guam, and is named after the collector Harry T. Conley.
