Calydiscoides
''Calydiscoides'' is a genus of monopisthocotylean monogeneans, included in the family Diplectanidae. The genus currently includes 16 species, which are all parasitic on the gills of marine fish of the family Lethrinidae and Nemipteridae. All species are from the Indo-Pacific Ocean. The type-species of the genus is ''Calydiscoides australis'' Young, 1969. Morphology All species of ''Calydiscoides'' are small animals, ranging 0.5–1 mm in length. As with most monogeneans, they are flat, with an anterior head bearing four oculi and head glands, a main elongate body and a posterior haptor. The digestive system includes an anterior muscular pharynx, and two lateral intestinal branches (or caeca); as in all Platyhelminthes, there is no anus. The haptor, in the posterior part of the body, is a specialized organ used to attach to the host (biology), host. The haptor includes sclerotized elements, namely a ventral bar, two lateral (dorsal) bars, two ventral hooks, and two dorsal ...

Calydiscoides Euzeti
''Calydiscoides euzeti'' is a species of monogenean of the family Diplectanidae. As all members of the family Diplectanidae, it has a single posterior testis and a single ovary that wraps the lateral caecum of the intestine. As all members of the genus Calydiscoides, it is characterized by the presence of lamellodiscs, which are specialized attachment organs made up of concentric lamellae, on the posterior part of its body. The species is distinguished from other species of the genus ''Calydiscoides'' by the shape and size of its male copulatory organ, which is elongate in shape with an anterior curved whip, and 70–83 μm in length. It is ectoparasite on the gills of two species of marine fish, emperors An emperor (from la, imperator, via fro, empereor) is a monarch, and usually the sovereign ruler of an empire or another type of imperial realm.
