You’re looking at the smallest snail ever discovered. Measuring just 0.86mm in height, ten of these extreme “microsnails” could fit within the eye of a single needle, though it’s not immediately obvious why they evolved to be so small. Called Angustopila dominikae, the new species of snail was discovered in China’s Guangxi province.
