The CapsalidaeSatyu Yamaguti, Yamaguti, S. (1963) Systema Helminthum IV. Monogenea and Aspidocotylea. London-New York, Interscience Publishers. 699 pp. is a family of monopisthocotylean monogeneans, which includes about 200 species. The monophyly of the Capsalidae is supported by possession of accessory sclerites in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. Their oncomiracidium (the free larva) is distinct from that of other families. Capsalids are parasite on various organs of marine fish (teleosts and elasmobranchs), including skin, fins and gills. Several capsalid species, such a ''Neobenedenia'' spp. are pathogenic, especially on maricultured fish. Included Genera Genera as recognized iWorMsare listed below. Recent molecular analyses have shown that several genera, which were defined on morphological characters, are not monophyletic.

Monogenea
Monogeneans are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.L.A. Tubbsa et al. (2005). "Effects of temperature on fecundity in vitro, egg hatching and reproductive development of ''Benedenia seriolae'' and ''Zeuxapta seriolae'' (Monogenea) parasitic on yellowtail kingfish Seriola lalandi". ''International Journal for Parasitology''(35), 315–327. Some monogeneans are oviparous (egg-laying) and some are viviparous (live-bearing). Oviparous varieties release eggs into the water. Viviparous varieties release larvae, which immediately attach to another host. The genus ''Gyrodactylus'' is an example of a viviparous variety, while the genus ''Dactylogyrus'' is an example of an oviparous variety. Signs and symptoms Freshwater fish that become infected with this parasite become let ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerites
A sclerite (Greek , ', meaning "hard") is a hardened body part. In various branches of biology the term is applied to various structures, but not as a rule to vertebrate anatomical features such as bones and teeth. Instead it refers most commonly to the hardened parts of arthropod exoskeletons and the internal spicules of invertebrates such as certain sponges and soft corals. In paleontology, a scleritome is the complete set of sclerites of an organism, often all that is known from fossil invertebrates. Sclerites in combination Sclerites may occur practically isolated in an organism, such as the sting of a cone shell. Also, they can be more or less scattered, such as tufts of defensive sharp, mineralised bristles as in many marine Polychaetes. Or, they can occur as structured, but unconnected or loosely connected arrays, such as the mineral "teeth" in the radula of many Mollusca, the valves of Chitons, the beak of Cephalopod, or the articulated exoskeletons of Arthropoda.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satyu Yamaguti
was a Japanese parasitologist, entomologist, and helminthologist. He was a specialist of mosquitoes and helminths such as digeneans, monogeneans, cestodes, acanthocephalans and nematodes. He also worked on the parasitic crustaceans Copepoda and Branchiura. Satyu Yamaguti wrote more than 60 scientific papersAnonymous. 1983. Special edition: A list of papers by Dr. Satyu Yamaguti and his collaborators and a notice on their distribution. The Meguro Parasitological Museum News, 153 (58), 1-12PDF and, more importantly, several huge monographs which are still in use by scientists all over the world and were cited over 1,000 times each. Education and career Satyu Yamaguti was born in Nagano Prefecture, Japan, 21 April 1894. He graduated from Okayama Medical College (1918), studied pathology at Tokyo University (1918-1925) and parasitology at the Institut für Tropenkrankheiten in Hamburg, Germany (1925-1926). He received his MD from Tokyo University in 1926 and was Dr. Sc. of Kyoto Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monopisthocotylea
The Monopisthocotylea are a subclass of parasitic flatworms in the class Monogenea. WoRMS (2019). Monopisthocotylea.

(2005). Monogenea Polyopisthocotylea (ectoparasitic flukes). In K. Rohde (Ed.), Marine Parasitology (pp. 55-63): CSIRO, Collingwood, Australia & CABI, Oxon, UK. Classification There are only two subclasses in the class Monogenea: * Monopisthocotylea. The name means "a single posterior sucker" - the attachment organ (the haptor) is simple. * Polyopisthocotylea. The name means "several posterior suckers" - the attachment organ (the haptor) is complex, with several clamps or suckers. The subclass Monopisthocotylea contains these orders: * Order Capsalidea * Order Dactylogyridea * Order Gyrodactylidea * Order Monocotylidea * Order Montchadskyellidea Example of species * ...
