Booklet development based on research identification of fiddler crab (Uca spp.) diversity in mangrove ecosystem [PDF]
JPBI (Jurnal Pendidikan Biologi Indonesia), 2018 The purpose of this development study is to develop research-based booklet for the identification of fiddler crab (Uca spp.) diversity. Some people do not yet know the ecological benefits of fiddler crabs.

Neuronal processing of translational optic flow in the visual system of the shore crab Carcinus maenas [PDF]
, 2011 This paper describes a search for neurones sensitive to optic flow in the visual system of the shore crab Carcinus maenas using a procedure developed from that of Krapp and Hengstenberg.

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 ...

The visual ecology of fiddler crabs
Journal of Comparative Physiology A, 2005 With their eyes on long vertical stalks, their panoramic visual field and their pronounced equatorial acute zone for vertical resolving power, the visual system of fiddler crabs is exquisitely tuned to the geometry of vision in the flat world of inter-tidal mudflats.

Handedness in fiddler crab fights [PDF]
Animal Behaviour, 2015 Asymmetric weapons are common in bilateral animals and, in some species, they can occur on either the left- or the right-hand side of the body (lateralization). Fiddler crabs (Uca spp, Decapoda: Ocypodidae) have an enlarged claw that is used in male–male combat over territories and in courtship displays.

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.

Criteria for coastwide crab condition sampling
“Prepared for the State/Federal Dungeness Crab Management Program.” Crabs molt every year. After they molt, their shells are soft and are not filled out with meat. It takes weeks for the crabs to fill out.
