Types of Parasite: On the basis of size parasites are classified into two types: Microparasite: They are characterized by their small size. Microparasite include bacteria, viruses and protozoans. Macroparasite: They are relatively larger as compared to microparasite. Macroparasite include flatworms, ticks, roundworms, fleas, lice and flukes. Parasites are classified into two types depending on where they live Ectoparasite: The parasites that live on the surface of the host are termed as ectoparasites. Mite, flea, ticks, lice etc are ectoparasites. Tick (an ectoparasite) Endoparasite: The parasites that live inside the body of the host are termed as endoparasites.
