Fiddler 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 کاملStatins for Renal Patients: A Fiddler on the Roof?
Atherosclerotic cardiovascular disease is the main cause of morbidity and mortality in chronic kidney disease patients. There is a raft of evidence showing that in the general population dyslipidaemia is associated with an increased risk of cardiovascular events, as well as with a greater prevalence of chronic kidney disease. Consequently, the use of statins in the general population with dysli...
متن کاملWhy do fiddler crabs build chimneys?
Chimneys are mud mounds built by fiddler crabs that encircle the entrance to their burrow. Their function in many species is unknown. In Uca capricornis, crabs of both sexes and all sizes build chimneys, but females do so disproportionately more often. There are no differences in the immediate physical or social environments between crabs with and without a chimney. Chimney owners spend less ti...
متن کاملThe fiddler crab Uca mjoebergi uses colour vision in mate choice.
Although the role of colour in mate choice is well known, few tests of colour vision have been based on mating behaviour. Females of the fiddler crab Uca mjoebergi have recently been shown to use claw coloration to recognize conspecific males. In this study I demonstrate that the females use colour vision for this task; preferentially approaching yellow claws over grey claws regardless of their...
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 ...
