My workplace is an industrial facility, about 40 acres in size and roughly rectangular in shape. There are two plastic lined water retention ponds over on one side and a spray field, which is sort of naturalized, in one back corner.
I was returning from a site inspection walk on a not warm afternoon. It was about 8 degrees C or 46F and I was just outside the main admin building when something caught my eyes. I veered towards it.
A crayfish (I called them crawdads when I was in Texas) was at least 100 meters from the nearest pond, and more than 200 meters as the crawdad crawls from the spray field. About 4 inches nose to end of tail. It had no business being on the concrete pad behind the building. I can only speculate how it got there.
I seemed to remember they they burrow down into soft mud in cold weather. So I took it back to the edge of the water at the spray field where it had at least a chance.
