Lepotrema Justinei
''Lepotrema justinei'' is a species of lepocreadiid digenean parasitic in the intestine of marine fish. It was described in 2018. This species was not characterised by molecular means but was distinguished from other species of the genus ''Lepotrema'' by morphological characteristics. It is the only species with more or less symmetrical testes, and, probably as a result, it tends to be broader than the other species. Etymology According to Bray, Cutmore & Cribb, the species was named ''justinei'' "after Professor Jean-Lou Justine of the Muséum National d’Histoire Naturelle, Paris, France, in recognition of his massive contributions to marine fish parasitology". Hosts and localities The masked triggerfish, ''Sufflamen fraenatum'', (Tetraodontiformes: Balistidae) is the type-host of ''Lepotrema justinei''. The type-locality is the Interior Lagoon near Récif Toombo, off Nouméa, New Caledonia ) , anthem = "" , image_map = New Caledonia on the globe (small islands mag ...

Digenea
Digenea (Gr. ''Dis'' – double, ''Genos'' – race) is a class of trematodes in the Platyhelminthes phylum, consisting of parasitic flatworms (known as ''flukes'') with a syncytial tegument and, usually, two suckers, one ventral and one oral. Adults commonly live within the digestive tract, but occur throughout the organ systems of all classes of vertebrates. Once thought to be related to the Monogenea, it is now recognised that they are closest to the Aspidogastrea and that the Monogenea are more closely allied with the Cestoda. Around 6,000 species have been described to date. Morphology Key features Characteristic features of the Digenea include a syncytial tegument; that is, a tegument where the junctions between cells are broken down and a single continuous cytoplasm surrounds the entire animal. A similar tegument is found in other members of the Neodermata; a group of platyhelminths comprising the Digenea, Aspidogastrea, Monogenea and Cestoda. Digeneans possess a vermifo ...

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 ...

Testes
A testicle or testis (plural testes) is the male reproductive gland or gonad in all bilaterians, including humans. It is homologous to the female ovary. The functions of the testes are to produce both sperm and androgens, primarily testosterone. Testosterone release is controlled by the anterior pituitary luteinizing hormone, whereas sperm production is controlled both by the anterior pituitary follicle-stimulating hormone and gonadal testosterone. Structure Appearance Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. For 85% of men, the right testis hangs lower than the left one. Measurement and volume The volume of the testicle can be estimated by palpating it and comparing it to ellipsoids of known sizes. Another method is to use cali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetraodontiformes
The Tetraodontiformes are an order of highly derived ray-finned fish, also called the Plectognathi. Sometimes these are classified as a suborder of the order Perciformes. The Tetraodontiformes are represented by 10 extant families and at least 349 species overall; most are marine and dwell in and around tropical coral reefs, but a few species are found in freshwater streams and estuaries. They have no close relatives, and descend from a line of coral-dwelling species that emerged around 80 million years ago. Description Various bizarre forms are included here, all radical departures from the streamlined body plan typical of most fishes. These forms range from nearly square or triangular (boxfishes), globose ( pufferfishes) to laterally compressed ( filefishes and triggerfishes). They range in size from '' Rudarius excelsus'' (a filefish), measuring just in length, to the ocean sunfish, the largest of all bony fishes at up to in length and weighing over 2 tonnes.

Nouméa
Nouméa () is the capital and largest city of the French special collectivity of New Caledonia and is also the largest francophone city in Oceania. It is situated on a peninsula in the south of New Caledonia's main island, Grande Terre, and is home to the majority of the island's European, Polynesian ( Wallisians, Futunians, Tahitians), Indonesian, and Vietnamese populations, as well as many Melanesians, Ni-Vanuatu and Kanaks who work in one of the South Pacific's most industrialised cities. The city lies on a protected deepwater harbour that serves as the chief port for New Caledonia. At the September 2019 census, there were 182,341 inhabitants in the metropolitan area of Greater Nouméa (), 94,285 of whom lived in the city (commune) of Nouméa proper. 67.2% of the population of New Caledonia live in Greater Nouméa, which covers the communes of Nouméa, Le Mont-Dore, Dumbéa and Païta.
