Which type of parasites are considered ectoparasites?

Ectoparasites are organisms that live on the exterior of a host and feed on their blood or other bodily fluids. Ticks and fleas are prime examples of ectoparasites, as they attach themselves to the skin of animals and humans to feed. These parasites can cause various health issues, including the transmission of diseases, skin irritation, and allergic reactions in both animals and humans.

In contrast, heartworms and roundworms are considered endoparasites, as they inhabit the interior of the host's body. Heartworms live in the heart and pulmonary arteries, while roundworms reside in the intestines. Internal worms typically cause different types of health issues and are treated distinctively compared to ectoparasites like ticks and fleas. Understanding the differences between ectoparasites and endoparasites is crucial for diagnosing and treating parasitic infections effectively.
