The Visual Acuity of the Fiddler-crab, Uca Pugnax
The visual acuity of the fiddler-crab can be measured at various illuminations by means of its response to a moving visual pattern. The method, although similar to that used by Hecht and Wolf for the bee and Hecht and Wald for Drosophila, must be modified to give consistent results. An explanation of the response to a visual pattern is given in terms of the structure of the eye. Visual acuity o...
متن کاملSemidome Building as Sexual Signaling in the Fiddler Crab Uca Lactea (brachyura: Ocypodidae)
During the mating season, males of the fiddler crab Uca lactea build semidomes of mud at the entrances of their burrows to which they attract females for mating in the upper intertidal zone. Related species build similar structures which either reduce aggression between neighboring males or attract sexually receptive females. Male U. lactea did not build disproportionately more semidomes as den...
متن کاملHigh e-vector acuity in the polarisation vision system of the fiddler crab Uca vomeris.
Polarisation vision is used by a variety of species in many important tasks, including navigation and orientation (e.g. desert ant), communication and signalling (e.g. stomatopod crustaceans), and as a possible substitute for colour vision (e.g. cephalopod molluscs). Fiddler crabs are thought to possess the anatomical structures necessary to detect polarised light, and occupy environments rich ...
متن کاملRelative growth of the fiddler crab, Uca sindensis(Crustacea: Ocypodidae) in a subtropical mangrove in Pohl Port, Iran
The relative growth of the fiddler crab Uca sindensis in Pohl Port was studied. Ten 0.5 m2 quadrates were randomly sampled monthly during low tide periods from October 2009 to September 2010. A total of 840 crabs, 449 (53.45%) males and 391(46.5%) females, were sampled. The Carapace width of males ranged from 5.5 to13.5 mm (mean ± SD) (8.92 ± 2.04), and of females from 5.0 to 11.5 mm (mean ± ...
متن کاملSexual Differences in Foraging Behavior of Fiddler Crab, Uca sindensis (Decapoda: Ocypodidae)
Fiddler crab females have two small feeding claws while males have only one the other is enlarged and used as a weapon as well as a mate attraction signal. The study was conducted on the small intertidal fiddler crab Uca sindensis in the Abi estuary near Bandar Abbas on the Persian Gulf. Data were collected from September 2007 to August 2008 in order to cover a wide range of ecological conditio...
