An ectoparasite is a parasite that lives on the surface of the body. A parasite is any organism that lives in or on another living being, gains an advantage by doing so, but causes disadvantage to the being it is living on. Ectoparasites gain nourishment from the skin of the organism that they live on or by sucking out the blood. Examples of ectoparasites are ticks, mites, lice, and various types of fungus. Unlike ectoparasites, endoparasites are parasites that live inside the body. Ectoparasite comes from the Greek word "ektos" meaning "outside," and the Greek word "parasitos" meaning "guest." Put the words together and you have "outside guest."
