      The smallest animal is a tricky one, because when you get smaller and smaller, you have to have fewer cells in your body, and can you be called an animal with just one cell? If yes, then an amoeba is the smallest animal, if not, then it’s probably be a kind of parasitic wasp that is a tenth of a mm long. The coolest small animal is definitely a tardigrade though!

      The smallest living thing is a bacteria though, and you can get thousands of these in one mm. They’re everywhere!

      It’s not the smallest, but may be the coolest!

      But this frog is apparently the smallest vertebrate
