Peniculus (crustacean)
''Peniculus'' is a genus of marine copepods in the family 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 ge .... 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''. Species There are 11 recognized species: References Siphonostomatoida Copepod genera Taxa named by Alexander von Nordmann {{copepod-stub ...

Peniculus Hokutoae
''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''. According to Ohtsuka, Nishikawa & Boxshall, this species is the first record of parasitism by the genus '' Peniculus'' on a mesopelagic myctophid Lanternfishes (or myctophids, from the Greek μυκτήρ ''myktḗr'', "nose" and ''ophis'', "serpent") are small mesopelagic fish of the large family Myctophidae.

The species was distinguished from other congeners by (1) the presence of a conical process anterior to the rostrum; (2) the secondary elongation of the first pedigerous somite; (3) the incorporation of the third and fourth pedigerous somites into the trunk; (4) the unilobate maxillule bearing two u ...

Alexander Von Nordmann
Alexander von Nordmann (24 May 1803 in Ruotsinsalmi (now Kotka), Finland – 25 June 1866 in Helsinki) was a 19th-century Finnish biologist, who contributed to zoology, parasitology, botany and paleontology.Leikola A (2001Nordmann, Alexander von (1803 - 1866) - eläintieteen professori, todellinen valtioneuvosKansallisbiografia. SKS Biografiakeskus Biography Nordmann was a son of an officer of the Russian army at the Ruotsinsalmi fortress, SE Finland. He started academic studies at the Imperial Academy of Turku, and at that time also acted as a curator of the entomological collections. In 1827 he continued studies in Berlin with the famous parasitologist and anatomist Karl Rudolphi. His first major work was a microscopical description of tens of parasitic worms and crustaceans from the eyes and other organs of fishes and other animals, including man. These included the enigmatic monogenean ''Diplozoon paradoxum''. In 1832 he was appointed a professor (teacher) at the Lyceum R ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
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] |

Symbolophorus Evermanni
''Symbolophorus evermanni'' is a species of fish in the family Myctophidae. It is widely distributed in the Indian and Pacific Oceans. The specific name ''evermanni'' honors ichthyologist Barton Warren Evermann. It is also known as Evermann's lanternfish or Evermann's lantern fish. ''Symbolophorus evermanni'' grows to standard length.

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.
