Light adaptation mechanisms in the eye of the fiddler crab Afruca tangeri
The Journal of comparative neurology, 2020 A great diversity of adaptations is found among animals with compound eyes and even closely related taxa can show variation in their light‐adaptation strategies. A prime example of a visual system evolved to function in specific light environments is the

Colouration and colour changes of the fiddler crab, Uca capricornis: a descriptive study. [PDF]
PLoS ONE, 2008 Colour changes in animals may be triggered by a variety of social and environmental factors and may occur over a matter of seconds or months. Crustaceans, like fiddler crabs (genus Uca), are particularly adept at changing their colour and have been the ...

Ecological Indicators, 2021 Human recreational visits to tidal flats increase trampling pressure, which has a significant impact on the coastal benthic ecosystem. The fiddler crab Austruca lactea, which inhabits the upper intertidal region, is endangered in temperate regions such ...

Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity [PDF]
, 2008 In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual ...

Photoreceptors and diurnal variation in spectral sensitivity in the fiddler crab Gelasimus dampieri
Journal of Experimental Biology, 2020 Colour signals, and the ability to detect them, are important for many animals and can be vital to their survival and fitness. Fiddler crabs use colour information to detect and recognise conspecifics, but their colour vision capabilities remain unclear.

PLoS ONE, 2015 In tropical regions, different species of fiddler crabs coexist on the mangrove floor, which sometimes makes it difficult to define species-specific habitat by visual inspection.

Sensitivity of Pagurus bernhardus (L.) to substrate-borne vibration and anthropogenic noise [PDF]
, 2015 © 2015 Elsevier B.V. Despite the prevalence of vibration produced by anthropogenic activities impacting the seabed there are few data and little information as to whether these are detected by crustaceans and whether they interfere with their behaviour ...

Fiddlers on the roof: elevation muddles mate choice in fiddler crabs [PDF]
Behavioral Ecology, 2014 Biological signaling usually occurs in complex environments, yet signals are most often studied in controlled experiments that strip away this complexity. Male fiddler crabs possess one enlarged claw that is waved during courtship displays, and females preferentially respond to larger claws and faster waves.

Poison Frog Colors Are Honest Signals Of Toxicity, Particularly For Bird Predators [PDF]
, 2012 Antipredator defenses and warning signals typically evolve in concert. However, the extensive variation across taxa in both these components of predator deterrence and the relationship between them are poorly understood.

Synchronous waving in fiddler crabs: a review [PDF]
Current Zoology, 2018 Many animals that use acoustic communication synchronize their mate attraction signals: individuals precisely time their calls to overlap those of their neighbors. In contrast, synchrony in the mate attraction displays of species with visual/motion-based signals is rare. It has only been documented in five species of fiddler crabs.
