Minute snails that just looked like black bits of dirt to the naked eye. Found under a loose bit of bark on a Taupata tree.
I hope we do not have carnivorous slugs ... the observation is for the wee snail.
I think most of these gastropods that I'm posting are the same species.
A snail without shell, or a slug with a hump?
Either way, a remarkable animal!
10 mm; closest visual match plus this fits location/habitat.
