Leptuca is a genus of fiddler crabs belonging to the family Ocypodidae. [1]
The species of this genus are found on the coasts of the Americas. [1]
They are small- to large-sized crabs with an adult carapace width of 5–25 mm in adults. [2] The front of their carapace is broad and they have short anterolateral margins with 0–2 posterolateral striae on the top of the carapace.
There are currently 30 species in the genus: [2] [3]
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.
