The parasitic way of life is a fascinating survival strategy that is actively studied by different types of scientists ranging from those interested in pest control, wildlife management, and human health, to those interested in evolution. As shown in the video below by the folks of SciShow, a number of parasites have life cycles that involve several hosts, and some parasites even control the behavior of their hosts and modify their bodies to maximize the parasite’s chances of survival (warning, you may not want to eat anything while you watch the video).
Parasites are also found in humans, and that, of course, includes you. No matter how much you clean yourself, you have probably quite a number of parasites living on or inside your body right now. In the video below, Anna Rothschild, the creator of Gross Science, talks about one of these parasites: face mites (warning, you should definitely not eat anything while you watch the video).
