Crawfish of Missouri - Spothanded Crayfish

The most distinctive feature of this moderately large crayfish is the presence of a conspicuous black spot on each pincer near the base of the movable finger. The carapace is reddish brown or olive-brown, with a narrow crescent-shaped dark bar across its hind margin. The abdomen is olive-green, with bright red outlining the free margins of all its segments. The pincers, carapace and abdomen are without conspicuous dark specks or blotches. Adults are about 2.3 to 5.4 inches in length. Common in the North Fork and ROLF.
