Define ectoparasite and endoparasite, and give suitable examples.
• Parasites that feed on the external surface of the host organism are called ectoparasites. The most familiar examples of this group are the lice on humans and ticks on dogs.
• Endoparasitesare those that live inside the host body at different sites (liver, kidney, lungs, red blood cells, etc.).’”The human liver fluke (a trematode parasite) is an endoparasite.
