Protanguillidae
''Protanguilla palau'' is a species of eel, the monotypic taxon, only species in the genus ''Protanguilla'' (first eel), which is in turn the only genus in its family (biology), family, Protanguillidae. Individuals were found swimming in March 2010 in a deep underwater cave in a fringing reef off the coast of Palau. Protanguillidae is a sister group to all other eels.Springer, V. G. (2015). The Gill-Arch Musculature of Protanguilla, the Morphologically Most Primitive Eel (Teleostei: Anguilliformes), Compared with That of Other Putatively Primitive Extant Eels and Other Elopomorphs, 103(2), 595–620. doi: 10.1643/CI-14-152 They are monophyletic, yet also strongly synapomorphic with all other eel species. Molecular analysis shows that all other eels are also monophyletic, showing that they may have broken off directly from the Protanguillidae. for this reason it's known as a "Living Fossil." Characteristics The body is very small and slender, about 18 cm long. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
