Polyopisthocotylea is a subclass of parasitic flatworms in the class Monogenea.[1][2][3]

Classification

There are only two subclasses in the class Monogenea:

  • Monopisthocotylea. The name means "a single posterior sucker" - the attachment organ (the haptor) is simple.
  • Polyopisthocotylea. The name means "several posterior suckers" - the attachment organ (the haptor) is complex, with several clamps or suckers.

The subclass Polyopisthocotylea contains the four following orders:[1]

Examples of species

  • gills
    of marine fish.
  • Diplozoon paradoxum, famous for its perfect monogamy, with the two individuals of the pair fused together
  • brassy trevally (Caranx papuensis)
    , "the monogenean which lost its clamps"
  • Polystoma integerrimum, a parasite of frogs which synchronises its breeding with that of its host
  • Hexanchus nakamurai
  • Chimaera monstrosa
    .
