Rhinos existed back in prehistoric times and when flourished in thousands, moving into diverse habitats across Africa, Asia, Europe and North America. Today, due to poaching and habitat loss, few remain. Since 1970 alone, the rhinoceros population has declined by approximately 90 percent, in line with the American Wildlife Foundation.

One of the differences that is noticeable in a very comparison of viruses and bacteria could be the height and width of the microorganism. Viruses less complicated smaller than bacteria. A typical virus is between 20 and 400 nanometers, while a bacterium can be as large as 1000 nanometers. The smallest bacteria are generally visible having a light microscope, while viruses require an electron microscope for observation.
