Crab

My greatest pleasure.

Thanks Joh

Judging by your location, I would guess that this is either Warren's Freshwater Crab, Potamonautes warreni, or else the Common RIver Crab, Potamonautes perlatus. It would help to see the back of the carapace. But, a very nice series of pictures... The crab looks alive.

Thank ForestDragon, will do.

Hi Mari, this is a wonderful series! I love the last image with the ray of light.

You should move this to the Arthropods section.
