Langkawi Fiddler Crab or Uca

Picture By Farlykhalid
Picture of the day by Farlykhalid. Shows Fiddler Crab or Uca (scientific name). Found in mangroves, salt marches etc2. Easily recognised by their distinctively asymmetric claws.

Fiddler crabs communicate by a sequence of waves and gestures;[2] males have an oversized claw or cheliped; used in clashes of ritualised combat of courtship over a female and signal their intentions between conspecifics. The movement of the smaller claw from ground to mouth during feeding underlines the crabs' common name; it seems that animal plays the larger claw somewhat like a fiddle. - Wikipedia

One thing for sure. Dont ever underestimate the claws. Nicely taken picture & thanks for the permission to share it with fellow Langkawian.. :) More pictures here.
