Leptuca Helleri
''Leptuca helleri'', commonly known as Heller's fiddler crab, is a species of fiddler crab endemic to the Galapagos Islands in the eastern Pacific Ocean. Taxonomy Previously a member of the genus ''Uca'', the species was transferred in 2016 to the genus ''Leptuca'' when ''Leptuca'' was promoted from subgenus to genus level.

Fiddler Crab
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 sexual dimorphism, 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 molting, 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 o ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Leptuca
''Leptuca'' is a genus of fiddler crabs belonging to the family Ocypodidae. The species of this genus are found on the coasts of the Americas. Description They are small- to large-sized crabs with an adult carapace width of 5–25 mm in adults. The front of their carapace is broad and they have short anterolateral margins with 0–2 posterolateral striae on the top of the carapace. Species There are currently 30 species in the genus: * '' Leptuca batuenta'' (Crane, 1941) (beating fiddler crab) * '' Leptuca beebei'' (Crane, 1941) (Beebe's fiddler crab) * ''Leptuca coloradensis'' (Rathbun, 1893) (painted fiddler crab) * '' Leptuca crenulata'' (Lockington, 1877) (Mexican fiddler crab) * '' Leptuca cumulanta'' (Crane, 1943) (heaping fiddler crab) * '' Leptuca deichmanni'' (Rathbun, 1935) (Deichmann's fiddler crab) * ''Leptuca dorotheae'' (von Hagen, 1968) (Dorothy's fiddler crab) * ''Leptuca festae'' (Nobili, 1902) (Festa's fiddler crab) * '' Leptuca helleri'' (Rathbun, 1902) ( ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Ocypodoidea
The Ocypodoidea, or ocypoid crabs, are a superfamily of crabs, named after the genus ''Ocypode''. It contains over 300 extant species in these eight families: * Camptandriidae Stimpson, 1858 * Dotillidae Stimpson, 1858 * Heloeciidae H. Milne-Edwards, 1852 * Macrophthalmidae Dana, 1851 * Mictyridae Dana, 1851 * 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 o ...
