Fiddler Crabs (Red-jointed, Sand, and Marsh)
Scientific Name: Uca minax, Uca pugilator, Uca pugnax
Three species of fiddler crabs are found in the Chesapeake Bay, the largest and most common being the red-jointed fiddler. All are active by day and may be seen above the hightide line. Distinctive to these crabs is the one outsized claw of the male, which he waves in a “fiddling” motion to attract a mate. The female has small claws of equal size.
Size: 1.5 in. (3.8 cm)
