Ectoparasites are organisms that live on or attached to the body of another organism, known as the host, for a period of time. This relationship is often mutually beneficial or neutral, but can sometimes be harmful to the host. Ectoparasites can be found in various taxonomic groups, including insects, mites, worms, and crustaceans.

There are several types of ectoparasites, including ticks, lice, fleas, mites, and leeches. Ticks and mites are ectoparasites that live on the skin of mammals and birds, while lice and fleas are common external parasites of humans and animals. Leeches are temporary ectoparasites that attach to the skin of their hosts for blood meals.

Ectoparasites have several mechanisms by which they attach to their hosts. Some use piercing mouthparts to puncture the host's skin, while others secrete adhesives or use suckers to attach. Ectoparasites can also develop specialized structures, such as barbed tongues or claws, to anchor themselves to the host's skin.

Ectoparasites can have significant impacts on the health and behavior of their hosts, including adding weight, causing anemia, and inflicting allergic reactions. Some ectoparasites can also transmit diseases to their hosts, such as tick-borne diseases and fleas that transmit typhus. In addition to their negative impacts, many ectoparasites also play important roles in their ecosystems, serving as hosts for other parasites and influencing the composition of host populations.
