Say hello to a tardigrade as seen through a laser scanning microscope. You might have heard them called water bears or moss piglets. The biggest tardigrades never get to be more than about 1.5 mm long, and most of them spend most of their days eating algae or bacteria and swimming around in droplets of water on moss or lichen. In fact, many kinds of tardigrades turn green when they eat because their bodies are transparent. They are fascinating … and adorable.
