Small snails

Did you know?

Acmella nana, a recently discovered species of the Acmella genus, is so small that, when first discovered, scientists could barely see it with the naked eye. ZooKeys, a journal on ecology, posted an article in 2015 describing the discovery of several additions to the total snail population of Borneo. The smallest thereof, had a shell width of no more than 0.37 millimetres!
