In this video you will see newborn Physa snail under a microscope. The size of this snail was ~0.2 mm, i.e. it was really hard to see it with the naked eye. With a magnification of 250x you can easily see the beating heart of a snail, because at this age it has an almost transparent shell. This snail lives in freshwater rivers, streams, lakes, ponds, and swamps.
