Ectoparasite: Parasites that live attached to the external body surface of the host are called ectoparasites, e.g. Leech and Ticks.
Endoparasites: Parasites that live attached to the internal body surfaces of the host are called endoparasites, e.g. roundworms and hookworms.
Final Answer:
Ectoparasites are creatures that live on a host’s skin and get their nutrition from it. E.g. Leech and Ticks.
Endoparasites are parasitic organisms that reside within the host. They can live with the host on a temporary, intermittent, or permanent basis. e.g. roundworms and hookworms.
