Anyone Identify this?

Not sure if this is the "American Invader" or a native crayfish - size is about 4" (100mm ish), found in the River Leen in Notts, but also observed some in a lake fed by the river :-

... and how do I add the dorsal view to this thread? Apologies, I'm a newbie

Like this...

(I found it in the image galleries, searched under your username, and copied the url!).


It looks likely to be the native White-clawed Crayfish to me, although I have no real experience with crayfish.
This pdf shows identification features.

Many thanks, Roy (for posting the image as well as a superb id leaflet)

Yes this is a native White-clawed Crayfish, alway good to see a few holding out.
