Phreatobius
''Phreatobius'', also known as cistern catfishes, is a genus of very small catfishes (order Siluriformes) from tropical South America. Taxonomy For quite some time ''Phreatobius cisternarum'' was the only species in the genus. However, two new species were described relatively recently in 2007, ''Phreatobius dracunculus'' and ''Phreatobius sanguijuela''. ''Phreatobius'' has been classified with a number of different families: Clariidae, Plotosidae, Trichomycteridae, Cetopsidae, and Pimelodidae. Most recently, it has been classified in Heptapteridae. Its phylogenetic position remains uncertain. The family placement of the genus has remained problematic and thus it is not classified in any of the existing families, though Fishbase treats it as a member of Heptapteridae. An undescribed species of ''Phreatobius'' lives in waterlogged leaf litter near (not in) streams. ''Phreatobius walkeri'', a ''nomen nudum'', is provided by the Guinness Book of World Records, to describe thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Phreatobius Cisternarum
''Phreatobius cisternarum'' is a species of catfish in the genus '' Phreatobius''. This Brazilian fish is one of the few fish species that live underground in phreatic habitats. It has proved problematic in its classification.Muriel-Cunha et al. (2005): page 328 Taxonomy ''Phreatobius cisternarum'' was collected in 1903 and first described by E. A. Goeldi in 1905.Muriel-Cunha et al. (2005): page 329 This fish species and genus were redescribed in 2005. Distribution and habitat ''Phreatobius cisternarum'' is found in Brazil. They inhabit underground habitats both north and south of the mouth of the Amazon River as well as the Marajó Island. This fish inhabits superficial, phreatic habitats, but does not live in the deeper artesian aquifers. These fish are found commonly in hand-dug wells on Marajó. These wells are 4–13 metres (13–43 ft) deep. In these wells, these fish are more common during the dry season when the water depth recedes to about 30 centimetres (12&nbs ...
