Gamacallum is a genus which belongs to the family Microcotylidae and class Monogenea. As all Monogenea, species of Gamacallum 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. [1]

Members of the genus Gamacallum are characterised by a short wide haptor with up to 25 pairs of clamps, an unarmed genital atrium and a penis occasionally armed with four spines, and a single unarmed vaginal pore. [1]

Metamicrocotyla is a genus which belongs to the family Microcotylidae and class Monogenea. It was created by Yamaguti in 1953 to include Metamicrocotyla bora and Metamicrocotyla filiformis from the gills off the flathead grey mullet Mugil cephalus (Mugilidae). As all Monogenea, species of Metamicrocotyla 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 Metamicrocotyla are characterized by a symmetrical haptor, a variable number of postovarian testes and with no cirrus nor vagina. their genital atrium is provided with paired groups of spines or hooks.
