<span class="mw-page-title-main">Siphonostomatoida</span> Order of crustaceans

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:

<i>Calanus</i> Genus of crustaceans

Calanus is a genus of marine copepod in the family Calanidae. The genus was split in 1974, with some species being placed in a new genus, Neocalanus. The following species are recognised:

<span class="mw-page-title-main">Ergasilidae</span> Family of crustaceans

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.

Acanthocyclops is a genus of copepod crustaceans in the family Cyclopidae. It was originally described by Friedrich Kiefer as a subgenus of Cyclops, and contains the following species:

Metacyclops is a genus of copepod crustaceans in the family Cyclopidae, containing 61 species, of which three are listed on the IUCN Red List – M. campestris from Brazil, M. gasparoi from Italy (vulnerable) and M. postojnae from Slovenia (vulnerable).

Neodiaptomus is a genus of freshwater copepods in the family Diaptomidae. It contains the following species, four of which are listed as vulnerable species on the IUCN Red List :

<span class="mw-page-title-main">Diaptomidae</span> Family of crustaceans

Diaptomidae is a family of freshwater pelagic copepods. It includes around 50 genera:

Acantholochus is a genus of parasitic copepods belonging to the family Bomolochidae. Its members can only be distinguished from the closely related genus Hamaticolax by the absence of an accessory process on the claw of the maxillipeds.

<i>Ergasilus</i> Genus of crustaceans

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.

Taeniacanthidae is a family of cyclopoid copepods in the order Cyclopoida. There are more than 20 genera and 120 described species in Taeniacanthidae.

Oleksandr Prokopovych Markevych was a Ukrainian zoologist, and a prolific helminthologist and copepodologist. He was professor and an Academician of the National Academy of Sciences of Ukraine.

<span class="mw-page-title-main">Pennellidae</span> Family of crustaceans

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.

<i>Caligus</i> Genus of crustaceans

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:

<span class="mw-page-title-main">Lernaeopodidae</span> Family of crustaceans

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.

<i>Acanthochondria limandae</i> Species of crustacean

Acanthochondria limandae is a species of copepods in the genus Acanthochondria. They are host-specific ectoparasites of two species of flatfish: the common dab and the European flounder. They attach themselves to the bases of the gill arches of their hosts. They can infest as much as 2 to 30% of fish in a given population.

Chondracanthus is a parasitic copepod genus in the family Chondracanthidae, containing the following species:

<span class="mw-page-title-main">Opecoelidae</span> Family of flukes

Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.

<i>Lepeophtheirus</i> Genus of crustaceans

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.
