Microsnails

Scientists have identified seven tiny new land snails in the Guangxi province of China, including Angustopila dominikae, seen here.

Angustopila dominikae measures a mere .86 mm in height, making it among the smallest land snails ever found. It is named after the wife of the scientist who discovered it. Because scientists have located only the single Angustopila dominikae shell from a soil sample, they cannot say with certainty that this species is, in fact, the smallest of the land snails. The smallest marine snail identified to date is Ammonicera minortalis, which is half the size of Angustopila dominikae. All snails with shells measuring less than 5 mm are colloquially known as microsnails.

Snails belong to the phylum Mollusca, which includes 85,000 invertebrates as wide-ranging as squid, slugs, sea cradles, and clams. Mollusks are found in the ocean, in fresh water, and on land.
