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.
Cichlidogyrus is a genus of monopisthocotylean monogeneans in the family Ancyrocephalidae. The type-species of the genus is Cichlidogyrus arthracanthusPaperna, 1960, by original designation. All the species of the genus are parasites on the gills of fish, namely African Cichlidae, Nandidae and Cyprinodontidae.
Protomicrocotylidae is a family of monogenean parasites in the order Mazocraeidea.
Clamps are the main attachment structure of the Polyopisthocotylean monogeneans.
These ectoparasitic worms have a variable number of clamps on their haptor ; each clamp is attached to the host fish, generally to its gill. Clamps include sclerotised elements, called the sclerites, and muscles. The structure of clamps varies according to the groups within the Polyopisthocotylean monogeneans; microcotylids have relatively simple clamps, whereas gastrocotylids have more complex clamps.
Lethacotyle fijiensis is a species of monogeneans of the family Protomicrocotylidae.
Lethacotyle vera is a species of monogenean of the family Protomicrocotylidae.
The haptor is the attachment organ of the monogeneans, a group of parasitic Platyhelminthes. The haptor is sometimes called opisthaptor to emphasize that it is located in the posterior part of the body, and to differentiate it from the prohaptor, a structure including glands located at the anterior part of the body. According to Yamaguti (1963), the chief adhesive organ of the monogeneans, the haptor, is posterior, more or less discoid, muscular, may be divided into alveoli or loculi, is usually provided with anchors, has nearly always marginal larval hooklets, or is in a reduced form with anchors. The haptor may consist of symmetrical or asymmetrical, sessile or pedunculate, muscular suckers or clamps with or without supporting sclerites; accessory adhesive organs may be present in form of armed plaques, lappets or appendices.
Pseudorhabdosynochus is a genus of monopisthocotylean monogeneans, included in the family Diplectanidae. The type-species of the genus is Pseudorhabdosynochus epinepheli .
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.
Pseudorhabdosynochus epinepheli is a diplectanid monogenean parasitic on the gills of species of groupers. It is the type species of the genus Pseudorhabdosynochus Yamaguti, 1958.
Hexabothriidae is a family of monogenean parasites. The family name was proposed by Emmett W. Price in 1942. The family includes 14-16 genera according to authors and about 60 species; all are parasitic on the gills of chondrichthyan fishes.
Gastrocotylidae is a family of polyopisthocotylean monogeneans. All the species in this family are parasitic on fish.
Plectanocotylidae is a family of polyopisthocotylean monogeneans. All the species in this family are parasitic on the gills of marine fish.
Microcotyle longirostri is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Microcotylidae.
Pseudaxine is a genus which belongs to the phylum Platyhelminthes and class Monogenea; all its species are parasites of fish.
Pseudaxine trachuri is a species of monogenean, parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae.
Gastrocotylinae is a sub-family of polyopisthocotylean monogeneans. All the species in this family are parasitic on fish.
Sibitrema is a genus which belongs to the phylum Platyhelminthes and class Monogenea; the only species included in this genus is parasite of fish.
Allopseudaxine is a genus which belongs to the phylum Platyhelminthes and class Monogenea; all its species are parasites of fish.
Cynoscionicola is a genus which belongs to the family Microcotylidae and class Monogenea. Species of Cynoscionicola 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. This genus was proposed by Price in 1962, to accommodate Cynoscionicola heteracantha and Cynoscionicola pseudoheteracantha . Members of Cynoscionicola are characterised by a genital atrium with two anterior muscular pockets armed with single row of hooked spines, and two posterior lateral muscular pouches armed with spines.
