But look at this little guy!
Going on a field walk with a bunch of astacologists is interesting. Quinton, with the classic, “I’ll have a go” Australian attitude, saw some chimneys of crayfish burrows under a footbridge, got down and got his hand nearly up to his elbow to retrieve this one. Still a juvenile, couldn't be sexed.
I said, “$5 to whoever can identify the species,” but had no takers. So still not sure myself what species this is.
At another end of the reserve, this was the only crayfish I saw, in Bascom House:
Additional: I have since heard that the burrower in the video above may be Cambarus diogenes.
