The origin of the first compound of the word is the Greek ἕλμινς - helmins, meaning "worm".
In the 18th and early 19th century there was wave of publications on helminthology; this period has been described as the science's "Golden Era". During that period the authors Félix Dujardin, [1] William Blaxland Benham, Peter Simon Pallas, Marcus Elieser Bloch, Otto Friedrich Müller, [2] Johann Goeze, Friedrich Zenker, Charles Wardell Stiles, Carl Asmund Rudolphi, Otto Friedrich Bernhard von Linstow [3] and Johann Gottfried Bremser started systematic scientific studies of the subject.

Microcotyle is a genus which belongs to the phylum Platyhelminthes and class Monogenea. Species of Microcotyle are ectoparasites that affect their host by attaching themselves as larvae on the gills of the fish and grow into adult stage. This larval stage is called oncomiracidium, and is characterized as free swimming and ciliated.
Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.
The Diplectanidae are a family of monopisthocotylean monogeneans. They are all parasitic on the gills of fish. Diplectanids are small animals, generally around 1 mm in length. As parasites, they can be extremely numerous, up to several thousand on an individual fish.
Telorchis is a genus of trematode parasites found in many herps, comprising around 70 species. This parasite is an indirect parasite, with a snail intermediate host and a reptile or amphibian definitive host. Typically found in the gastrointestinal tract of their definitive host, telorchids attach to the wall of the intestinal tract with their ventral sucker, or acetabulum.

Prosomicrocotyla is a genus of monogenean. Species of Prosomicrocotyla are ectoparasites that affect their host by attaching themselves as larvae on the gills of the fish and grow into adult stage. This larval stage is called oncomiracidium, and is characterized as free swimming and ciliated. Members of Prosomicrocotyla are characterised by a spatulate body; an haptor divided into two separate frills bordering posterior half of body proper, commencing at level of ovary; a non differentiated cirrus; a genital atrium forming a sucker-like structure armed with spines and a single middorsal vagina.
