Karyorelictea
Karyorelictea is a class (biology), class of ciliates in the subphylum Postciliodesmatophora. Most species are members of the microbenthos community, that is, microscopic organisms found in the marine interstitial habitat, though one genus, ''Loxodes'', is found in freshwater. The majority of karyorelict taxa have not been cultivated in the laboratory, although clonal lines of ''Loxodes'' have been developed. Systematics According to Lynn (2008), the Karyorelictea class is divided into three orders: * Loxodida, containing the families Cryptopharyngidae and Loxodidae; * Protoheterotrichida, containing the families Aveliidae and Geleiidae; * Protostomatida, containing the families Kentrophoridae and Trachelocercidae. These three order (biology), orders were defined morphology (biology), morphologically, and have been confirmed with molecular phylogenetics. An additional family, Wilbertomorphidae, is of uncertain affiliation and has not been assigned to an order. Nuclear dimorphi ...

Loxodes
''Loxodes'' is a genus of karyorelictean ciliates, belonging to Loxodidae. It is the only known karyorelictean ciliate that lives in freshwater habitats. The genus is known for its distinctive morphology, including a relatively large, flattened body and unique nuclear structures. It is also known to exhibit fascinating behaviours, such as geotaxis and light sensitivity. Etymology The term ''Loxodes'' derives from the ancient greek (), meaning "oblique, tilted". According to Ehrenberg, who first described the genus, Loxodes means oblique and refers to the anterior margin of the ciliated lip of the organisms in this genus. Type species ''Loxodes rostrum'' (Müller, 1773) Ehrenberg, 1830 History of knowledge ''Kolpoda rostrum'' was the first loxodid discovered and described. The genus ''Loxodes'' was first proposed in 1830. Ehrenberg moved ''Kolpoda rostrum'' into the genus ''Loxodes'' and set it as the type species. Research has explored the geotaxis of ''Loxodes'' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
