Big S, little s, what begins with S?
I was hiking around Baldwin Hills in the heat of the day, and was surprised to find a snail in this arid environment — camped out on the stem of a dessicated plant, no less.
It was not alone.
Attuned to the phenomenon, I realized the back wall of the visitors center was well populated, too. The park employees said yes, they had noticed, and they'd sent off to an ecologist for identification. (Perhaps it is the common garden snail?)
