Ocypodidae
The Ocypodidae is a family of semiterrestrial crabs that includes ghost crabs and fiddler crabs. These crabs are found along tropical and temperate shorelines worldwide. Some genera previously classified within the Ocypodidae family have been reclassified into separate families within the superfamily Ocypoidea, such as Dotillidae and Macrophthalmidae. In 2016, the genus Uca was divided into 13 genera through the elevation of its subgenera to genus status, among other taxonomic changes. Further refinements have been made to the family's organization, resulting in 4 subfamilies, approximately 13 extant genera, and around 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 * '' G ...

Ucinae
The fiddler crab or calling crab can be one of the hundred species of semiterrestrial marine crabs in the family Ocypodidae. These crabs are well known for their extreme sexual dimorphism, where the male crabs have a major claw significantly larger than their minor claw, whilst females claws are both the same size. The name fiddler crab comes from the appearance of their small and large claw together, looking similar to a fiddle. 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 ''Afruca tangeri'' which is 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. Whilst fiddler crabs are currently split into two subfamilies of Gelasiminae and Ucinae, there is still phylogenetic and taxonomical debate as to whether the movement fr ...

Afruca
''Afruca'' is a genus of fiddler crabs belonging to the family Ocypodidae. ''Afruca tangeri'', the only species in this genus, lives along the Atlantic coasts of western Africa and southwestern Europe. Description ''Afruca tangeri'' is one of the largest species of fiddler crab, with a carapace up to wide, and up to long. The males have one claw much larger than the other, which they use for communication. Body colouration is fairly dull for a fiddler crab, but individuals are a variety of colours from dull shades of brown, to bright orange, red or purple. Distribution The range of ''Afruca tangeri'' extends from southern Portugal southwards to Angola;. It is the only fiddler crab species on the Eastern Atlantic coast and the most abundant crab in The Gambia. Taxonomy ''Afruca tangeri'' was first described by Joseph Fortuné Théodore Eydoux in 1835 as ''Gelasimus tangeri'', but for many years it was part of the genus ''Uca'', which then contained all the fiddler crabs worl ...

''Austruca'' is a genus of Indo-west Pacific fiddler crabs in the family Ocypodidae. There are about 13 described species in this genus.

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. However, ...

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 species, 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 (entomologist), Friedrich Weber in 1795, using the type species ''Ocypode ceratophthalma, 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 (biology), family Ocypodidae. Ghos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mu ... [...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 grayish 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, Massachus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
