Detailed explanation-1: -An ectoparasite lives on the outside of its host; a flea is an example of an ectoparasite. Endoparasites, such as tapeworms, live within their host. Parasite avoidance could have some serious implications for behavioral ecology.
Detailed explanation-2: -Although the term ectoparasites can broadly include temporarily blood-sucking arthropods such as mosquitoes, this term is generally used more narrowly to refer to pathogens such as ticks, fleas, lice, parasitic flies and mites that attach or burrow into the skin and remain there for relatively long periods of time2.
Detailed explanation-3: -Ectoparasites. Ectoparasites include scabies (Sarcoptes scabiei), the common bed bug (Cimex lectularius), fleas, and lice, including the body louse (Pediculus humanis), pubic louse (Phthirius pubis), and head louse (Pediculus humanus capitis).
