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 [update] , the World Register of Marine Species includes the following species: [1]
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:
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.
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:
Taeniacanthidae is a family of cyclopoid copepods in the order Cyclopoida. There are more than 20 genera and 120 described species in Taeniacanthidae.
Chondracanthidae is a family of parasitic copepods, usually found infecting the branchial chamber of demersal fishes. It comprises the following genera:
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.
Pontella is a marine copepod genus in the family Pontellidae. It is an organism that bears three lenses in the eye. The outer has a parabolic surface, countering the effects of spherical aberration while allowing a sharp image to be formed.
Hamaticolax is a genus of parasitic copepods belonging to the family Bomolochidae. Its members can only be distinguished from the closely related genus Acantholochus by the presence of an accessory process on the claw of the maxillipeds. It includes the following species:
Pilumnus is a genus of crabs, containing the following species:
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.
Chondracanthus is a parasitic copepod genus in the family Chondracanthidae, containing the following species:
Acanthochondria is a genus of copepods, containing the following species:
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.
Eudactylinidae is a family of copepods, most of which live as parasites on the gills of elasmobranch fishes; two genera lives on the gills of teleost fishes.
Eudactylina is a genus of copepods. They parasitise elasmobranch fishes.
