Arietellidae is a family of copepods belonging to the order Calanoida. [1]
The family contains the following genera: [2]
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 40 recognised families:
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
The Cyclopidae are a family of copepods containing more than half of the 1,200 species in the order Cyclopoida in over 70 genera.
Acartia is a genus of marine calanoid copepods. They are epipelagic, estuarine, zooplanktonic found throughout the oceans of the world, primarily in temperate regions.
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:
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 genera are:
Misophrioida is an order of copepods, containing the following families:
Nicothoidae is a family of copepods, containing the following genera:
Metridinidae is a family of copepods, comprising three genera – Gaussia, Metridia and Pleuromamma. It has also been referred to as "Metridiidae", but following a petition to the International Commission on Zoological Nomenclature, that name has been restricted to the family Metridiidae Carlgren, 1893, based on the anthozoan genus Metridium. All species in the family can produce blue-green bioluminescence; the light is produced in glands, whose position varies between genera.
Augaptilidae is a family of copepods.
Lernaeopodidae is a family of parasitic copepods. The females are typically large and fleshy, and attach to the host permanently using a plug made of chitin called the bulla. The males cling on to the females using their antennae. They parasitize both marine and freshwater fish. Some lernaeopodids, including Clavella and Salmincola, can have negative impacts on fish in aquaculture.
Philichthyidae is a family of copepods, containing the following genera:
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.
Peniculus minuticaudae is a species of parasitic pennellid copepod. It is known from the northeast Pacific Ocean. It was originally described in 1956, redescribed in 2012, and its complete life cycle has been elucidated on the cultured threadsail filefish, Stephanolepis cirrhifer in 2013.
Peniculus hokutoae is a species of parasitic pennellid copepod. It was described in 2018 from a single female. The type-host is the myctophid fish Symbolophorus evermanni and the type-locality is off Japan. The Japanese name of this species is hokuto-kozutsu-hijikimushi.
Misophriidae is a family of copepods belonging to the order Misophrioida.
Hyperbionycidae is a family of crustaceans belonging to the order Calanoida.
