Parasites are living things that have evolved to live inside or on another type of organism. This relationship is non-mutual, meaning the parasites gets more from it than the host. Famous parasitic relationships include humans and head lice, rats being mind controlled by toxoplasma gondii and the youngest sibling in any family. Even T.Rex had parasities. Parasites also cause some of the worst diseases we know, such as malaria, so understanding them is really important.
