| | | Both signal crayfish?
I'm hoping for a settling of an argument between myself and the others here in my house!
On a walk through Pamber Forest in north Hampshire on Sunday we noticed at least 4 crayfish in a small section of the stream. I'm pretty convinced that all were signal crayfish but the others think the one at the top of this picture is the native species. It appeared slightly smaller and was defending the nook it was in against the other, which only has one claw.
Can anyone settle the argument and tell us they are both signal crayfish please?!

My screen is too small to see your image clearly, but if your go to the Gallery and search for crayfish in the invertebrate section then you can see for yourself the differences. |

They look like signals to me.

They're both Signals - you can see the white flash on the pincer joints. |

Both Signals - take them home and cook them. Native Crays die off very rapildly due to Crayfish Plague once Signals get into the the water. |
