@Setanta,
But they don't live underground...they live deep in the plants......under leaves and such. They seal themselves off with dried slime, I suppose it is, so they don't dehydrate.
May well be the fluoride and the humidity.
They get more water when I water them than they do from rain.
But last night they were FRISKY! Prancing they were. hot to trot. Seemed to find the storm exciting. They weren't feeding...they were gathering at the tops of plants looking frenzied. I was surprised fights weren't breaking out.
Boida...why are you surprised I have snail? Did you want a few million as pets?
