I have only cared for snails for a few months, but I am starting to identify wake/sleep cycles too.
I did think it was hilarious that they rest for a few hours and then become little grazing/mating machines for 30 hours straight...

sounds about right!
I only want more studies because many people isolate instances like these and say "well that doesn't necessarily mean other snail species sleep". I am a majoring biology and I come across that 'burden of proof' mentality so often, especially in regard to animals.
It kind of reminds me of the big hullabaloo a couple years back about the chimpanzee who was collecting stones to throw at zoo-goers. It was supposedly so profound to science that an ape would premeditate anything, but the idea that it was *such* a surprise to people seemed almost ridiculous to me.
