Crayfish -
A dorsal (top) picture should show at least the carapace (head to rostrum). A ventral (bottom) picture should show a detailed picture of the gonopods (first swimmeret in males) or the annulus ventralus (receptacle in females). See this post regarding a HIGH quality image of gonopods. Other pictures such as full dorsal shots, mandibles, or claws are welcome and may be necessary. See this link on crayfish anatomy to understand terms used above.

Please include information such as state, drainage or watershed, county, and stream name where the specimen was observed. Send information to state authorities in malacology (mussels) and astacology (crayfish) with credible and accurate information when a rare species may have been encountered.

Second link is broken.

But, yeah, don't think we're going to get much more than "crayfish" here, unfortunately.

The strong light lateral stripe on the abdomen and the dark tubercles on the side of the carapace all point to Procambarus clarkii. It is likely that species considering its abundance, but could possibly be another member of the subgenus (Scapulicambarus).
