Red Swamp Crayfish
Adults of this species are dark red (nearly black on the carapace) and have a wedge-shaped black stripe on the abdomen. Juveniles are a uniform gray, sometimes overlain by dark wavy lines. The pincers are narrow and long. The carapace is not separated at the middle by a space (areola). The carapace is conspicuously granular (roughened) in adults. The rostrum has lateral spines or notches near its tip. This crayfish most closely resembles the White River crayfish, which differs most obviously in having an areola. Young of the White River crayfish usually have spots on the carapace.
