More signaling for earlier mating: Conspicuous male claw waving in the fiddler crab, Uca perplexa
Article Abstract:
A study on the relation between the time males spend waving to females and the time they subsequently spend underground in their burrow guarding their mates until they ovulate and fertilizing their eggs was studied. The study concluded that the male courtship display of the fiddler crab Uca perplexa is a conspicuous claw waving that is directed at females to attract them to their burrows for mating and the male species modulate their investment in courtship according to changing levels of female responsiveness to courtship.

Fighting in fiddler crabs Uca mjoebergi: What determines duration?
Article Abstract:
An investigation examined whether contest duration in the Australian fiddler crab Uca mjoebergi is determined with individual thresholds or mutual assessment of fighting ability, and which type of game theory model is most appropriate for this species. Results suggest that in Uca mjoebergu, though, individual cost thresholds may determine duration, larger opponents might inflict those costs more rapidly, consistent with the cumulative assessment game of animal conflict.

Long searches for male-defended breeding burrows allow female fiddler crabs, Uca crenulata, to release larvae on time
Article Abstract:
Observations on mate-searching female California fiddler crabs, showed that these crabs conducted much longer searchers than have been reported for other animals. The size of the holes of the burrows on incubation explained the reason for the sampling of many male burrows when searching for a mate by the females.
