We finally got a second glimpse of this creature!
No idea what this is called. We’ve been calling it the “zebra naked snail” – it’s a black-bodied snail-like creature, about an inch long, with yellow spots and a white and black patterned mini-shell. I’d seen him for an instant a few weeks ago (by the time I realized that I had no idea what he was, he’d vanished), and then Kevin got photographic proof of the second sighting.
Very neat.
