Siphonostomatoida

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:

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.

Hatschekiidae is a family of copepods in the order Siphonostomatoida.

Dirivultidae is a family of crustaceans belonging to the order Siphonostomatoida.

Kroyeriidae is a family of copepods in the order Siphonostomatoida.

Pseudocycnidae is a family of marine copepods in the order Siphonostomatoida.

Asterocheridae is a family of copepods belonging to the order Siphonostomatoida.

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 (Heterocladius and Jusheyus).

Eudactylina is a genus of copepods. They parasitise elasmobranch fishes.

Pennella is a genus of large copepods which are common parasites of large pelagic fishes. They begin their life cycle as a series of free-swimming planktonic larvae. The females metamorphose into a parasitic stage when they attach to a host and enter into its skin. The males are free swimming. Due to their large size and mesoparasitic life history there have been a number of studies of Pennella, the members of which are among the largest of the parasitic Copepoda. All species are found as adults buried into the flesh of marine bony fish, except for a single species, Pennella balaenopterae whic

Ommatokoita is a monotypic genus of copepods, the sole species being Ommatokoita elongata. However, a specimen has been found on the skin of the great lanternshark (Etmopterus princeps), which has been assigned to the genus but not the species.
