A fish parasite, the isopod Cymothoa exigua, replacing the tongue of a Lithognathus. Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life.

There may be as many as 300,000 species of parasites affecting vertebrates, [9] and as many as 300 affecting humans alone. [10] Helminths of importance in the sanitation field are the human parasites, and are classified as Nemathelminthes (nematodes) and Platyhelminthes, depending on whether they possess a round or flattened body, respectively.

Criticism of this system began in the latter half of the 19th century, with the realization that many organisms met the criteria for inclusion among both plants and animals. For example, the algae Euglena and Dinobryon have chloroplasts for photosynthesis , like plants, but can also feed on organic matter and are motile , like animals.
Parasites are organisms which derive sustenance from its host while causing it harm. [2] The study of parasites and parasitic diseases is known as parasitology . [ 3 ] Medical parasitology is concerned with three major groups of parasites: parasitic protozoa , helminths , and parasitic arthropods . [ 2 ]
Predatory nematodes include Phasmarhabditis hermaphrodita which is a lethal parasite of gastropods such as slugs and snails. [61] Some members of the genus Steinernema such as Steinernema carpocapsae and Steinernema riobrave are generalist parasites of webworms, cutworms, armyworms, girdlers, some weevils, wood-borers and corn earworm moths.
