August 6, 2011

Red tips of claws.

Moved
Moved from Crayfishes.

Orconectes
Confirmed ID as species Orconectes virilis (juvenile) after reviewing original full size image via email correspondence.

ID based on location plus appearance of rostrum/acumen (with marginal spines), presence of cervical spines, chelae and open areola.

Other photos?
You don't happen to have any other photos of an up close view of the carapace/rostrum do you? I can't quite tell if there are marginal spines at the base of the acumen or not.
