Pennellidae
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. Genera There are 24 genera: *'' Allotrifur'' Yamaguti, 1963 *''Cardiodectes'' C. B. Wilson, 1917 *'' Creopelates'' Shiino, 1958 *'' Exopenna'' Boxshall, 1986 *'' Haemobaphes'' Steenstrup & Lutken, 1861 *'' Impexus'' Kabata, 1972 *'' Lernaeenicus'' C. B.

Peniculisa
''Peniculisa'' is a genus of marine parasitic copepods in the family Pennellidae. Biology Organisms from this genus are often found attached to the bodies and fins of fishes in the South Pacific and Indian oceans. Individual fishes have been reported to harbor hundreds of ''Peniculisa wilsoni'' parasites. Infection intensity is rarely cited for other ''Peniculisa'' species. ''Peniculisa'' parasitic infections tend to be limited to tetraodontiform and pomacentrid fishes. Taxonomy There are nine recognized species of ''Peniculisa'': *''Peniculisa bellwoodi'' Boxshall, 1989 – parasite of '' Pomacentrus amboinensis'' *''Peniculisa bicaudata'' Shiino, 1956 *''Peniculisa crassa'' Uyeno & Nagasawa, 2010 – parasite of ''Lactoria fornasini'' *''Peniculisa elongata'' Uyeno & Nagasawa, 2010 – parasite of ''Ostracion cubicus'' *''Peniculisa furcata'' Krøyer, 1863 – parasite of '' Paramonacanthus barnardi'' *''Peniculisa ohirugi'' Uyeno & Nagasawa, 2010 – parasite of ''Pomacentru ...

Protosarcotretes
''Protosarcotretes'' is a genus of marine copepods in the family Pennellidae. Its type-species is ''Protosarcotretes nishikawai''. This genus exhibits the most plesiomorphic states in the first to fourth legs of pennellids, and is differentiated from two closely related pennellid genera '' Sarcotretes'' and '' Lernaeenicus'' by the morphology of the oral appendages. Species According to Ohtsuka, Lindsay & Izawa (2018), three species are included in the genus: * ''Protosarcotretes nishikawai'' Ohtsuka, Lindsay & Izawa, 2018 This species is a parasite of the Pacific viperfish, ''Chauliodus macouni''. * ''Protosarcotretes multilobatus'' (Lewis, 1959) Ohtsuka, Lindsay & Izawa, 2018 * ''Protosarcotretes gnavus ''Protosarcotretes'' is a genus of marine copepods in the family Pennellidae.

Lernaeenicus Sprattae
''Lernaeenicus sprattae'' is a species of copepod in the family Pennellidae. It is a parasite of the European sprat (''Sprattus sprattus'') and certain other fish and is sometimes known as the sprat eye-maggot. Distribution ''Lernaeenicus sprattae'' is a parasite of the European sprat (''Sprattus sprattus'') in northwestern Europe and the European pilchard (''Sardina pilchardus'') in southwestern Europe, the Mediterranean Sea, and the Black Sea. Ecology This copepod has a large number of developmental-stages, some free-living and some parasitic. Two naupliar stages and the first copepodid stage are free-living and are followed by a second copepodid stage where the larva grasps a host fish. This is followed by four chalimus stages (nymphal stages) where the larvae are parasitic on the host. During the next stage, the adults are free-living and mate, the male dying soon after copulation. The female moults once more before reattaching to a sprat, either on its external surface or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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: * Archidactylinidae Izawa, 1996 *Artotrogidae Brady, 1880 *Asterocheridae Giesbrecht, 1899 *Brychiopontiidae Humes, 1974 *Caligidae Burmeister, 1835 * Calverocheridae Stock, 1968 *Cancerillidae Giesbrecht, 1897 *Codobidae Boxshall & Ohtsuka, 2001 *Coralliomyzontidae Humes & Stock, 1991 * Dichelesthiidae Milne-Edwards, 1840 *Dichelinidae Boxshall & Ohtsuka, 2001 *Dinopontiidae Murnane, 1967 *Dirivultidae Humes & Dojiri, 1980 *Dissonidae Yamaguti, 1963 *Ecbathyriontidae Humes, 1987 *Entomolepididae Brady, 1899 *Eudactylinidae C.

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennella
''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'' which can be found in the muscles and blubber of cetaceans and occasionally other marine mammals, and is the largest species of copepod. Biology Like most parasitic copepods it is the female which is parasitic in ''Pennella'' while the males are free swimming. The female has a two host life cycle and egg production commences when an inseminated female settles on its ultimate host, usu ...
