Cymothoida
Cymothoida is the name of a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing. Classification Cymothoida contains these superfamilies and families: *Superfamily Anthuroidea Leach, 1814 ** Antheluridae Poore & Lew Ton, 1988 ** Anthuridae Leach, 1814 ** Expanathuridae Poore, 2001 ** Hyssuridae Wägele, 1981 ** Leptanthuridae Poore, 2001 ** Paranthuridae Menzies & Glynn, 1968 *Superfamily Cymothooidea Leach, 1814 **Aegidae White, 1850 **Anuropidae Stebbing, 1893 ** Barybrotidae Hansen, 1890 **Cirolanidae Dana, 1852 ** Corallanidae Hansen, 1890 ** Cymothoidae Leach, 1818 **Gnathiidae Leach, 1814 ** Protognathiidae Wägele & Brandt, 1988 ** Tridentellidae Bruce, 1984 *Superfamily Cryptoniscoidea Kossmann, 1880 **Asconisc ...

Cymothoidae
The Cymothoidae are a family of isopods in the suborder Cymothoida found in both marine and freshwater environments. Cymoithoids are ectoparasites, usually of fish, and they include the bizarre "tongue-biter" ('' Cymothoa exigua''), which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body. '' Ceratothoa oestroides'' is one of the most devastating ectoparasites in Mediterranean aquaculture. Around 40 genera and more than 380 species of cymothoid are recognised. Species of the Cymothoidae are generally found in warmer waters and rarely in the cool and cold climates. Characteristics Cymothoids exhibit various adaptations to their parasitic lifestyles. As juveniles, they are not specific in their requirements, and attach themselves temporarily to the skin of any fish. They produce anticoagulants and suck the fish's blood. They detach from their first host and later find another host. When they have found the correct species of fish fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isopoda
Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are grazers, or filter feeders, a few are predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or bottom of freshwater bodies of water, but some taxa can swim for a short distance. Terrestrial forms move around by crawling and tend to be found in cool, moist places. Some species are able to roll themselves into a ball as a defense mechanism or to conserve moisture. There are over 10,000 identified species of isopod worldwide, with around 4,50 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurydice Pulchra
''Eurydice pulchra'', the speckled sea louse, is a species of isopod crustacean found in the northeast Atlantic Ocean. The generic name is for the nymph Eurydice of Greek mythology; the specific name means beautiful in Latin. The range of the species extends from Norway to the Atlantic coast of Morocco, but not into the Mediterranean Sea. It lives in the intertidal zone on sandy shores. It has large eyes and long antennae, is grey to brown in colour, and has black spots (each one a chromatophore Chromatophores are cells that produce color, of which many types are Biological pigment, pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods.

Anuropidae
''Anuropus'' is a genus of isopods in the suborder Cymothoida. , it is the only genus in the family Anuropidae. Taxonomic history The genus ''Anuropus'' was first circumscribed by the English zoologist Frank Evers Beddard in 1886. His new genus coincided with his description of the type species, '' A. branchiatus''. Beddard placed ''Anuropus'' in the family Cymothoidae, but in 1893, Thomas Roscoe Rede Stebbing wrote it "may have greater claims to be the type of a distinct family, Anuropidæ". In 1903, Hans Jacob Hansen thought ''Anuropus'' might possibly belong to the subfamily Cirolaninae or perhaps a new subfamily Anuropinae.

Gnathiidae
The Gnathiidae are a family of isopod crustaceans. They occur in a wide range of depths, from the littoral zone to the deep sea. The adults are associated with sponges and may not feed. The juvenile form is known as a 'praniza', and it is a temporary parasite of marine fish. These forms are not larvae; ''Gnathiidae'' instead become parasitic during the manca stage. Mancae of the ''Gnathiidae'' closely resemble the adult form, however they lack the final pair of pereiopods. Taxonomy in the family relies on male characters, such that females and juveniles cannot be reliably identified. The family contains 182 species, divided among the following genera: *'' Afrignathia'' Hadfield & Smit, 2008 *'' Bathygnathia'' Dollfus, 1901 *'' Bythognathia'' Camp, 1988 *'' Caecognathia'' Dollfus, 1901 *'' Elaphognathia'' Monod, 1926 *'' Euneognathia'' Stebbing, 1893 *'' Gibbagnathia'' Cohen & Poore, 1994 *''Gnathia ''Gnathia'' is a genus of isopod crustaceans, containing the following sp ...
