The Fish and Wildlife Service's Ding Darling National Wildlife Refuge, is home to the fiddler crab. 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. March 29, 2021, Sanibel Isla
