We saw hundreds of these fiddler crabs climbing the muddy banks of the river. Here’s what I found about them on Britannica.com.

Fiddler crabs often occur in large numbers on beaches in temperate to tropical regions of the world. They live in water-covered burrows up to 30 cm (about 1 foot) deep and feed on algae and other organic matter. Common North American species include the marsh fiddler crab (Uca pugnax), the china-back fiddler (U. pugilator), and the red-jointed fiddler (U. minax). These species, which range in body size from about 2.5 to 3 cm (1 to 1.2 inches), occur all along the Atlantic coast of the United States. The males of all species are more brightly coloured than the females. Colours range from coral red, bright green, and yellow to light blue.
