What kind of cambarus is it?

Hi,
I photograph the female cambarus.
You can see more photos in my album:

Is it cambarus coosae, spicatus, scotti, girardianus, fasciatus, species or speciosus?



Please anybody tell me what kind of cambarus it is.
Thanks a lot!!

I would call it coosae based on the wide areola, color, rostrum shape, wide body, and what look to be relatively short stocky chelae. Fasciatus and coosawatee have large gaps in their palms and huge chelae and speciousus is much darker with longer chelae, a different rostrum shpae and is a little narrower through the body.

Thanks for your reply.
I also asked some friends.
He thinks the yellow female cambarus is longirostris.

That's his reply:

I have no doubt about the other crayfish though, it is definitely Cambarus longirostris. This species is very variable not only in color but also in structure. I am presently working with this species and it actually may represent several species that are undescribed. Look at my website http://users.alink.com/appy/ and then click on the link for Crayfishes of the upper Tennessee Basin at the bottom you can see all the different varieties of Cambarus longirostris.

I always ask him a lot of questions. Thanks for his patience.

This is Cambarus longirostris. I search it from google.

So what's your opinions?
I also put the other two cambarus that have some green and blue color in another album.
They should be coosae.......maybe........ = =

He thinked the male cambarus with fouling be speciosus due to his so wide areola before.
It's very puzzling. The white lines show the areola width (the width between the gill chambers), the yellow lines show the two rows of tubercles on the palm and the blue lines show the cervical spine.



But he thinks it is probably Cambarus coosae now.

I photographed the three cambarus together.
Hope it' useful to compare their species.

I'm not the specialist. Need your help to distinguish its species.
Oh, do you have some methods to let them mate?

Thanks again.

Okay, the problem I see with C. longirostris complex is that it is found in the Upper Tennessee River basin. The species you listed are found in the Coosa River basin. So where did you collect the crayfish from? There is absolutely no gap in the palm of your crayfish either, and C. longirostris and C. longulus has an enourmous gap, as does C. fasciiatus (i'm guessing the Mobile Basin equivalent to C. longirostris). C. coosawatee and C. manningi have similar claws but have hairy palms, yours does not. In fact, I've got two C. longirostris and C. longulus specimens in my hand as we speak and so if you can provide a better pciture that shows the chela and palm gap and any setae (hair) I'm not convinced that is what it is. I do not profess to be a crayfish expert and Whitney is, but I'm going to have to disagree with this one.

Hi,
Sorry, I don't know where it comes from.
I live in Taiwan...east asia.
I got it from my friend 9 months ago.
He sells cambarus.
I send photos to him.
He says it's cambarus coosawattae.
I tell him my cambarus doesn't have red color in its joints of pereiopods.
He says this is male coosawattae's characteristic.
Mine is female, so She doesn't have this.
But I can't sure if he's right.
What's your opinion?
thanks

I certainly hope it is not Cambarus coosawatee because that is state endangered species in Georgia. As is specious, scotti, and fasciatus. I think your supplier may have some questions to answer as to how they are acquiring them and exporting.
