Fleas are classified as ectoparasites, which means they live on the outside of their host animal. These small insects attach themselves to the fur or skin of mammals and birds, where they feed on the host's blood. Ectoparasites differ from endoparasites, which reside within the host's body.

In contrast, tapeworms, heartworms, and pinworms are all examples of endoparasites. They thrive inside the host's gastrointestinal system or body, often causing various health issues. Understanding the distinction between ectoparasites and endoparasites is important when studying parasitology and animal health.
