Crayfish - Cambarus robustus Crayfish - Cambarus robustus

Moved from Cambarus.

Moved from Orconectes.

I don't think this is Orconectes. Based on the carapace, rostrum and chelae, I'd say it's a species of Cambarus, probably diogenes or bartonii. Given the habitat (stream), I'd go with bartonii. But it's still a bit of guesswork IDing from photos.

Moved from Crayfishes.

Looks like Orconectes, I'm not quite sure which species though.

not a clue which species,
but I'm anxious to learn more about these. I figured it would be more likely to get noticed with the other Crayfish than in ID request.

Moved from ID Request.
