[1] [2] Before 2016, the species was known as Uca subcylindrica. In 2016, the subgenus Leptuca was promoted to the genus level ...
Leptuca speciosa, commonly known as the brilliant fiddler crab or the longfinger fiddler crab, is a species of fiddler crab native to the southern United States, Mexico, and the Caribbean.

The fiddler crab or calling crab can be one of the hundred species of semiterrestrial marine crabs in the family Ocypodidae. [2] 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. [3]
Fiddler crabs generally have very simple 10–40 cm “J-shaped” burrows, [29] while sesarmid crabs that burrow often create complex, branching burrows that can reach over 100 cm in depth. [27] Both types of crab significantly increase the surface area of the sediment and water/air interface to similar extents when scaled for relative ...
It prefers areas of lower salinity than other fiddler crabs, [3] and can be found in great numbers along the banks of tidal streams, even at distances greater than 50 km (31 mi) from the sea. [ 4 ] Minuca minax was formerly in the genus Uca , but in 2016 it was placed in the genus Minuca , a former subgenus of Uca .
The crabs had been plentiful in the years prior, puzzling scientists and crabbers alike. A rapid warming of water temperatures and loss of sea ice from 2018 to 2019 made conditions less favorable ...
Leptuca leptodactyla, commonly known as the thin-fingered fiddler crab or the western Atlantic fiddler crab, is a species of fiddler crab native to the western Atlantic coast of the Americas. [ 1 ] Taxonomy
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.
