Eudactylinidae
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 Teleostei (; Greek ''teleios'' "complete" + ''osteon'' "bone"), members of which are known as teleosts ), is, by far, the largest infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all extant species of fish.

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.

Nemesis (genus)
In ancient Greek religion, Nemesis, also called Rhamnousia or Rhamnusia ( grc, Ῥαμνουσία, Rhamnousía, the goddess of Rhamnous), was the goddess who personifies retribution for the sin of hubris: arrogance before the gods. Etymology The name ''Nemesis'' is related to the Greek word νέμειν ''némein'', meaning "to give what is due", from Proto-Indo-European ''nem-'' "distribute". Family Nemesis has been described as the daughter of Oceanus, Erebus, or Zeus, but according to Hyginus she was a child of Erebus and Nyx. She has also been described, by Hesiod, as the daughter of Nyx alone. In the Theogony, Nemesis is the sister of the Moirai (the Fates), the Keres (Black Fates), the Oneiroi (Dreams), Eris (Discord) and Apate (Deception). Some made her the daughter of Zeus by an unnamed mother. In several traditions, Nemesis was seen as the mother of Helen of Troy by Zeus, adopted and raised by Leda and Tyndareus. According to the poet Bacchylides, she was the mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Eudactylina'' is a genus of copepods that parasitise elasmobranch Elasmobranchii () is a subclass of Chondrichthyes or cartilaginous fish, including sharks (superorder Selachii), rays, skates, and sawfish (superorder Batoidea). Members of this subclass are characterised by having five to seven pairs of gil ... fishes.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

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] |
