Cichlidogyrus

Cichlidogyrus is a genus of monopisthocotylean monogeneans in the family Ancyrocephalidae. The type-species of the genus is Cichlidogyrus arthracanthus Paperna, 1960, by original designation.[1] All the species of the genus are parasites on the gills of fish, namely African Cichlidae, Nandidae and Cyprinodontidae.[1] [2] [3][4] [5] [6]

Paperna, 1960 [1]

Species of Cichlidogyrus are parasitic in many clichlid species in the Lake Tanganyika; a recent study (2016) has shown that species which are parasite on deep-water fish show reduced parasite-host specificity in comparison to species from littoral waters, probably an adaptation to low host availability.[7]

According to Antoine Pariselle and Louis Euzet, 71 species of Cichlidogyrus were known in 2009 [3] - new species have been described since. Nikol Kmentová, Milan Gelnar, Stephan Koblmüller and Maarten P.M. Vanhove estimated that the number of species was more than 100 in 2016[8] and Chahrazed Rahmouni, Maarten P. M. Vanhove and Andrea Šimková listed 111 species in 2017.[9]

Species of Cichlidogyrus have been introduced in various parts of the world, as alien species, where there hosts, particularly tilapia, have been introduced.[10]

Species

Among many species, a few examples:

gollark: They can, however, go offroad, and launch nuclear weapons.
gollark: Still about 40% the speed of a train.
gollark: My spidertron is maximally optimized for speed so it uses a bunch of batteries and solar rather than a portable fusion reactor.
gollark: 100 something per hour with the maximum exoskeletons.
gollark: μhahahaha.
