Tiny quick gloss snails
Large number of tiny snails, focused in on just a few here. I wasn't sure if juvenile or fully grown as their shells were no more than 4 mm diameter. I learned that they are fully grown. So tiny!
One can see a few out of their shells on zoom.
Non-indigenous population here in Australia. Native to North America.
