You are right, and it certainly had toes at one point. I had it in a tank with one of its siblings a while ago and suspect it lost them then. The feet are slowly regrowing and I can just about see toes now, but its taken a long time.
Time for a little update.
Since reading Mr Cyclones comment I have put them in a more aquatic set up. I did have a heater in with them, but when it started making scary sounds I removed it. The water temperature is approx. 15 degrees at the moment. They enjoy eating earthworms and the largest is now close to 3 inches in length.
