Did you know there are more living things on and inside your body alone than on the entire Earth? And the world is full of this micro-stuff! You can even see some bacteria with your own eyes. The largest bacterium in the world lives in the coastal waters of Namibia. Its length is 3/4 mm, and its larger than, say, a grain of sand or salt!
More than half as small is a dust mite these pests that bug you at night only grow to be around 1/3 mm. By the way, remember those amoebas from your biology classes? Theyre the same size as dust mites. A single strand of human hair is just 1/10 mm thick. So wanna know more about how huge our planet really is? Then lets look through the super-powerful microscope!
