Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a subclass of the class Hexanauplia. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.
Siphonostomatoida is an order of copepods, containing around 75% of all the copepods that parasitise fishes. Their success has been linked to their possession of siphon-like mandibles and of a "frontal filament" to aid attachment to their hosts. Most are marine, but a few live in fresh water. There are 39 recognised families:
The family Argulidae contains the carp lice or fish lice – a group of parasitic crustaceans of uncertain position within the Maxillopoda. Although they are thought to be primitive forms, they have no fossil record. The Argulidae are the only family in the order Arguloida, although a second family, the Dipteropeltidae, has been proposed.
Deoterthridae is a family of crustaceans in the subclass Tantulocarida, classified under the class Maxillopoda. It contains the following genera: It has been accepted as Cumoniscidae by the World Register of Marine Species.
The Cyclopoida are an order of small crustaceans from the subclass Copepoda. Like many other copepods, members of Cyclopoida are small, planktonic animals living both in the sea and in freshwater habitats. They are capable of rapid movement. Their larval development is metamorphic, and the embryos are carried in paired or single sacs attached to first abdominal somite.
Poecilostomatoida are an suborder of copepods. Although it was previously considered a separate order, recent research showed it to be nested within the Cyclopoida
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.
Speleophria is a genus of marine copepods in the family Speleophriidae. It contains the following species:
Bomolochidae is a family of copepods parasitic on marine fishes. Most species parasitize the gills of fish, but some species live in the nostrils or on the eyes of their hosts. The family contains just over 150 species from the following genera:
Centropagidae is a family of copepods. Its members are particularly known as plankton in coastal waters and in fresh water in Australia and southern South America. They are also found on subantarctic islands and in lakes in Antarctica.
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:
Geoffrey Allan Boxshall FRS is a British zoologist, and Merit researcher at the Natural History Museum, working primarily on copepods.
Speleophriidae is a family of copepods, comprising seven genera. All are restricted to anchialine caves, with the exception of Archimisophria, which is found in the hyperbenthos of the depths of the Atlantic Ocean. The seven genera are:
Misophrioida is an order of copepods, containing the following families:
Nicothoidae is a family of copepods, containing the following genera:
Daniel Boxshall was an English footballer who played as a winger. He made over 140 Football League appearances in the years after the Second World War.
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca.
The Hexanauplia constitute a class of crustaceans, comprising two groups: the Copepoda and the Tantulocarida. The former subclass Thecostraca was elevated to class rank and removed from Hexanauplia in 2021.
Tisbidae is a family of copepods belonging to the order Harpacticoida.
Hyalopontius is a genus of crustaceans belonging to the monotypic family Megapontiidae.
