Interaction between path integration and visual orientation during the homing run of fiddler crabs
Foraging fiddler crabs form a strict spatial relationship between their current positions and burrows, allowing them to run directly back to their burrows when startled even without visual contacts. Path integration (PI), the underlying mechanism, is a universal navigation strategy through which animals continuously integrate directions and distances of their movements. However, we report that ...
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...
متن کاملBurrow surveillance in fiddler crabs. II. The sensory cues.
Using crab-like dummies, we have shown previously that fiddler crabs [Uca vomeris (McNeill)] defend their burrows against intruders in a burrow-centred frame of reference. The crabs respond whenever an intruder approaches to within a certain distance of the burrow entrance, and this distance is independent of the approach direction. We show here that the crabs combine information from the path ...
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 کاملVisual 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...
