These two 'dads are from my neighbor's pond.

It's more like 75-80 according to Chris Skelton as of about a month ago. It's automatically only one of the last 29 on the list since it's a Procambarus sp.

I agree. Definitely Procambarus. It looks like a P. clarkii as far as shape, color, etc, but the areola is open, so I'm going to say it's likely a P. alleni.

Edit: If you wouldn't mind sending me a male I could key it out exactly for you. As far as I can tell from the pictures, it looks like it might be in the subgenus Villalobosus, but I can't tell for sure because I can't tell if the if their are hooks on the third and fourth pair of legs or not.

Thanks. How do I determine a male and how do I mail a male?

The one in your picture was a male. They have a pair of gonopods that goes up between the legs. Here is a picture of the male gonopods:

As far as shipping, use a small rubbermaid container with holes in the top. Put just enough water to cover up the cray, so that when oxygen runs out he can breath atmospheric air. Pack it with crumpled newspaper for cushion.

Won't the package get thrown around and allow the water to leak out?

I realize you are both in Georgia but anyone shipping P. clarkii around willy nilly should be aware of importation/exportation/possession regulations because it is considered invasive/exotic in most states.

Yes your package would probably leak everywhere if the container had holes. Without the ability to keep their gills moist crayfish cannot breath atmospheric oxygen for very long. A dry container will most likely have a dead crayfish upon reciept. I'd suggest a sealed container.

Nope. No P. alleni in that state. Could be a P acutus but for some reason it just doesn't look right for acutus.

Any crayfish can be shipped. I've checked the laws. Thanks for your concern though. :D

I thought about P. acutus too, but there is to big of a gap in the areola for it to be P. acutus. If he can send me a Form I male I can probably get it keyed out pretty quickly.

The blue vein ventrally on abdomen also indicates red swamp instead of white river crayfish.

Steve you need to read thoroughly. I said I realize you two are within the same state, but ANYONE (as in ANYONE ELSE) shipping P. clarkii or other invasive/exotics should be aware of any laws governing such activity.

That said the rostrum and areola are not characteristic of P. clarkii, the chela are quite interseting though...I don't think it is acutus.
