Visual signalling and sexual selection in male fiddler crabs
Similar to many other species of fiddler crabs, the interactions of Uca tangeri are influenced by 2 characteristic visual signals: the waving d~sp lay performed by males with their enlarged claw, and the building of structures (mudballs) around the burrow entrance. This study focused on male signalling, male-male competition and female mate choice Female choice and male mating success were inve...
متن کاملExperiments with robots explain synchronized courtship in fiddler crabs
surprise that a lowlevel sensorimotor manipulation systematically influences the behavior in a task only implicitly evoking the notion of number magnitude. However, sensory and motor processes, which have originally evolved for basic interactions with the environment, are reportedly exploited during abstract cognition [15]. Intriguingly, as head turning can influence one’s spontaneous spatial e...
متن کاملFiddler crabs
What are fiddler crabs? Fiddler crabs belong to the genus Uca. They are members of the ocypodid family of brachyuran crabs, the most recent marine animals to have invaded land. They spend the first part of their life as aquatic plankton and only settle in the intertidal zone after their last larval moult. Adults live in burrows on intertidal mudand sand-flats within dense, mixedage, mixed-sex a...
متن کاملReproducing on Time When Temperature Varies: Shifts in the Timing of Courtship by Fiddler Crabs
Many species reproduce when conditions are most favorable for the survival of young. Numerous intertidal fish and invertebrates release eggs or larvae during semilunar, large amplitude, nocturnal tides when these early life stages are best able to escape predation by fish that feed near the shore during the day. Remarkably, some species, including the fiddler crabs Uca terpsichores and Uca deic...
متن کاملNatural visual cues eliciting predator avoidance in fiddler crabs.
To efficiently provide an animal with relevant information, the design of its visual system should reflect the distribution of natural signals and the animal's tasks. In many behavioural contexts, however, we know comparatively little about the moment-to-moment information-processing challenges animals face in their daily lives. In predator avoidance, for instance, we lack an accurate descripti...
