Physical Description
The Sand fiddler crab is approximately 1.5 inches(38mm) wide and 1.0 inch(25mm) long. All fiddler crabs are similar in shape, having a smooth carapace and a square-shaped body. The eyes are found at the ends of two long and slender, movable eyestalks located in the center of the carapace. Male fiddler crabs are brighter in color, having a purple grey or blue carapace with irregular markings of black or brown. The females have equal-sized claws and generally have a much more subdued coloration on their carapaces. Being that they are crabs they are considered decapods or animals with ten limbs; although both of their claws are not referred to as legs, they are actually chelipeds or claws. Males have a common characteristic of one large pincer. This pincer, which is usually brightly colored, can either be on the right or left side and is at least four times larger than the other. The large cheliped can be as fifty percent as massive as the rest of the male combined. Uca pugilator use the large claw to defend their burrows and attract mates. Fiddler crabs even get their name from the male's large claw.
