by rubbing their big claw on there body
Fiddler crabs dig burrows to create a safe shelter from predators and to regulate their body temperature. Burrowing also helps them stay hydrated by preserving moisture in the burrow. Additionally, male fiddler crabs use their burrows to attract mates and establish dominance within their territory.
All animals with exoskeletons, including crabs, molt.
Fiddler crabs belong in various groups (taxa) in their biological classification: kingdom Metazoa; phylum Arthropoda; subphylum Crustacea; class Malacostraca; order Decapoda; infraorder Brachyura; family Ocypodidae; genus Uca. About a hundred species of fiddlers have been described.

Male crabs attract female crabs primarily through visual displays and courtship behaviors. They may use vibrant colors, elaborate movements, or specific postures to signal their fitness and readiness to mate. Additionally, some species release pheromones to enhance attraction, creating a chemical signal that draws females closer. These strategies help males to demonstrate their health and genetic quality, making them more appealing to potential mates.
male frogs will croak to attract female frogs.
For some crab species, claws are different between males and females, like larger claws on male fiddler crabs, or color on blue crabs. All male crabs have a triangular shape near the rear on their underside, though, while females have a broad round marking in that same location.
You can tell a fiddler crab's gender by its claws. A female fiddler crab has two claws, the same size. A male fiddler crab has one large claw and one small claw.
There is no difference in size between female and male hermit crabs.
