Ocypodidae
The Ocypodidae are a family of semiterrestrial crabs that includes the ghost crabs and fiddler crabs. They are found on tropical and temperate shorelines around the world. Some genera previously included in the family are now treated as members of separate families in the superfamily Ocypodoidea, such as the Dotillidae and Macrophthalmidae. In 2016, the genus Uca was split into 13 genera by elevating its subgenera to genus rank, among other things. Further refinements have been made to the organization of the family, which has 4 subfamilies, about 13 extant genera, and about 180 described species as of 2020. The majority of the Ocypodidae species are fiddler crabs, the exceptions being the members of the genus ''Ocypode'', ghost crabs, and the genus ''Ucides'', mangrove crabs. Genera These genera belong to the family Ocypodidae: * '' Afruca'' Crane, 1975 * ''Austruca'' Bott, 1973 * '' Cranuca'' Beinlich & von Hagen, 2006 * '' Gelasimus'' Stimpson 1862 * ''Leptuca'' Bott, 1973 * ...

Ucinae
The fiddler crab or calling crab may be any of more than one hundred species of semiterrestrial marine crabs in the family Ocypodidae, well known for their sexually dimorphic claws; the males' major claw is much larger than the minor claw, while the females' claws are both the same size. A smaller number of ghost crab and mangrove crab species are also found in the family Ocypodidae. This entire group is composed of small crabs, the largest being slightly over two inches (5 cm) across. Fiddler crabs are found along sea beaches and brackish intertidal mud flats, lagoons, swamps, and various other types of brackish or salt-water wetlands. Like all crabs, fiddler crabs shed their shells as they grow. If they have lost legs or claws during their present growth cycle, a new one will be present when they molt. If the large fiddle claw is lost, males will develop one on the same side after their next molt. Newly molted crabs are very vulnerable because of their soft shells. They a ...

Gelasiminae
Gelasiminae is a subfamily that pertains to nine out of the eleven fiddler crab genera within the family Ocypodidae. Taxonomy The subfamily includes 94 species within nine genera. The genera are split into two tribes that are geographically distant. Tribe Gelasimini consists of species native to the Indo-West Pacific whereas Tribe Minucini consists of species native to the Americas.

Ocypodinae
Ghost crabs are semiterrestrial crabs of the subfamily Ocypodinae. They are common shore crabs in tropical and subtropical regions throughout the world, inhabiting deep burrows in the intertidal zone. They are generalist scavengers and predators of small animals. The name "ghost crab" derives from their nocturnality and their generally pale coloration. They are also sometimes called sand crabs, though the name refers to various other crabs that do not belong to the subfamily. Characteristics of the subfamily include one claw being larger than the other, thick and elongated eyestalks, and a box-like body. The differences in claw sizes, however, are not as marked as in male fiddler crabs. The subfamily includes 22 species in two genera. Taxonomy Ocypodinae is one of two subfamilies in the family Ocypodidae, the other being the fiddler crab subfamily, Ucinae. Both subfamilies have members in which one of the claw-bearing legs (the chelipeds) is much larger than the other. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocypode
''Ocypode'' is a genus of ghost crabs found in the sandy shores of tropical and subtropical regions throughout the world. They have a box-like body, thick and elongated eyestalks, and one claw is larger than the other in both males and females. They inhabit deep burrows in the intertidal zone. They are primarily nocturnal, and are generalist scavengers and predators of small animals. The genus contains 21 species. Taxonomy The genus ''Ocypode'' was first established by the German entomologist Friedrich Weber in 1795, using the type species '' Cancer ceratophthalmus'' described by the German naturalist Peter Simon Pallas in 1772. ''Ocypode'' was previously the only genus classified under the ghost crab subfamily Ocypodinae until 2013, when Katsushi Sakai and Michael Türkay reclassified the gulf ghost crab into a separate genus, '' Hoplocypode''. It belongs to the family Ocypodidae. Ghost crabs of the genus ''Hoplocypode'' can be distinguished from those in ''Ocypode'' ...

Leptuca Pugilator
''Leptuca pugilator'', the sand fiddler crab, Atlantic sand fiddler crab, or Calico fiddler, is a species of fiddler crab that is found from Massachusetts to the Gulf of Mexico. It lives in burrows in coastal and estuarine mud-flats, and can be extremely abundant. It can be differentiated from the morphologically similar ''Minuca pugnax'' and ''Minuca minax'' by the smoothness of the inside of its claws. One claw is larger than the other, and can be much larger than the crab's body, at up to long. ''Leptuca pugilator'' was formerly in the genus ''Uca'', but in 2016 it became a member of the genus ''Leptuca'', a former subgenus of ''Uca''. Description The carapace is square in shape, tapering slightly to the rear; it can reach a width of , but is typically up to wide and long. The space between the eyes is much shorter than the eyestalk. The males have one extremely enlarged chela (claw), which they use to claim their territory and fight with other males. The claw can be much l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ocypode Quadrata
The Atlantic ghost crab, ''Ocypode quadrata'', is a species of ghost crab. It is a common species along the Atlantic coast of the United States, where it is the only species of ghost crab; its range of distribution extends from its northernmost reach on beaches in Westport, Massachusetts, south along the coasts of the tropical Western Atlantic Ocean to the beach of Barra do Chui, in Rio Grande do Sul in southern Brazil. Description Adults are greyish or the color of straw, and around wide at maturity. They must return to water periodically to moisten their gills, and when larvae must be released into the sea, but are otherwise terrestrial. Their stalked compound eyes can swivel to give them 360° vision. Young crabs are cryptically colored to blend in with their sandy habitats. Distribution Atlantic ghost crabs are found from Santa Catarina north to Massachusetts, USA. They have been recorded in Block Island, Rhode Island, Nantucket, Massachusetts, Martha's Vineyard, Massachuse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
