The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years : taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is Gryllus and the first use of the family name "Gryllidae" was by Francis Walker.
Alexander von Nordmann was a 19th-century Finnish biologist, who contributed to zoology, parasitology, botany and paleontology.
Ostrea is a genus of edible oysters, marine bivalve mollusks in the family Ostreidae, the oysters.
Convolutidae is a family of acoels. It contains more than a third of all known acoel species.
Ergasilidae is a widespread family of copepods and comprises many species. The type genus is Ergasilus. With a few doubtful exceptions all ergasilids are parasitic on fishes.
Ergasilus is a genus of copepod crustaceans occurring in both the ocean and fresh water, often called gill lice. The females are parasitic upon the gills of fishes. Being copepods, gill lice have a single median eye on their head. The second antennae are modified into prehensile pincers. Male gill lice are free-living.
Pennellidae is a family of parasitic copepods. When anchored on a host, they have a portion of the body on the outside of the host, whereas the remaining anterior part of the parasite is hidden inside tissues of the host.
Caligus is a genus of sea lice in the family Caligidae. The species are parasites of marine fishes and could be vectors of viruses. As of 2017, the World Register of Marine Species includes the following species:
Gyrodactylidae is a family of flatworms in the order Gyrodactylidea.
Gyrodactylus is a genus of parasitic flatworms in the family Gyrodactylidae.
Lepeophtheirus is a genus of sea louse. The best-known species is L. salmonis, the salmon louse. Other species include L. pectoralis, which uses flatfish as its host, particularly the European flounder, and is also the type species of the genus Lepeophtheirus.
Tracheliastes is a genus of parasitic copepods, containing the following species:
Diplozoidae is a family of monogeneans in the order Mazocraeidea. In all species of this family, the bodies of the two hermaphroditic members of a couple are permanently fused for life. These monogeneans are parasitic on the gills of freshwater fish.
Diplostomidae is a family of trematodes in the order Diplostomida.
Peniculus is a genus of marine copepods in the family Pennellidae. They occur worldwide and typically parasitize coastal or epipelagic fish, with the exception of Peniculus hokutoae that was found parasitizing a mesopelagic myctophid, Symbolophorus evermanni.
Achtheres is a genus of arthropods belonging to the family Lernaeopodidae.
Apatemon is a genus of flatworms belonging to the family Strigeidae.
Diplozoon is a genus of flatworms belonging to the family Diplozoidae.
Neodiplostomum is a genus of flatworms belonging to the family Diplostomidae.
Ergasilus curticrus is a freshwater parasitic copepod named in 2015. Described from the Orinoco river basin, it was found solely to be hosted by individuals of the Characiform fish species Bryconops giacopinii. Of those located in South America, it is one of only five species in its genus to be found outside of Brazil.
