Re: 30 cm
I have seen a increadibly huge individual in a very deep well near the Rio Tierar, Sierra de Gredos, this summer. The animal must be stuck there, already for several years. It appears it doesn't mind at all. This one certainly comes near 30 cm, if it isnt that large already. I could not capture it back than due to the rusty ladder leading into the well. If anyone of the Spanish people is interested please pm me and go measure it!
