Parasites are defined as organisms which live on or within some other living organisms deriving sustenance from it, the organism in which he lives is an host. A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles. A parasite and its host evolve together. The parasite adapts to its environment by living in and using the host in ways that harm it. Hosts also develop ways of getting rid of or protecting themselves from parasites. There are different types of parasitic relationships they are symbiosis, Commensalism, Parasitism etc. Symbiosis is defined as the permanent association between two specifically distinct organisms dependent on each other. Commensalism is an association between host and parasite in which one parasite is benefitted and other is neither benefitted nor harmed .If the parasite is pathogenic and harms its host the condition is known as parasitosis.
