White River Crayfish
Adults of this species are usually a deep burgundy red with a black V-shaped stripe on the abdomen. Juveniles are gray with dark spots scattered over the carapace. The pincers are long and narrow. The carapace is separated at its middle by a space (areola). The carapace is conspicuously granular (roughened) in adults. The White River crayfish resembles the red swamp crayfish (Procambarus clarkii). The latter species differs most notably in lacking an areola. Young of the red swamp crayfish are usually plain or striped, not spotted.
