Eartheater
Geophagini is a tribe of cichlids from the subfamily Cichlinae, the American cichlids. It is the sister taxon to the clade which includes the Cichlasomatini and Heroini. Fishes in the Geophagini are distributed from Panama south to Argentina, it is the most speciose of the seven tribes within the Cichlinae and it is subdivided into three sub-tribes, Acarichthyina, Crenicaratina, and Geophagina which together contain over 200 species. Geophagines show morphological and behavioural specialisations to enable them to sift the substrates within their mouths so that they can separate benthic invertebrates from substrates dominated by sand or silt. Classification The Geophagini are classified as follows: * Subtribe Acarichthyina Kullander, 1998 ** Genus '' Acarichthys'' C. H. Eigenmann, 1912 ** Genus '' Guianacara'' Kullander & Nijssen, 1989 * Subtribe Crenicaratina Kullander, 1998 ** Genus '' Biotoecus'' C. H. Eigenmann & C. H. Kennedy, 1903 ** Genus '' Crenicara'' Steindachner, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophagus
''Geophagus'' is a genus of cichlids that mainly live in South America as far south as Argentina and Uruguay, but a single species, ''G. crassilabris'' is from Panama.Mattos, J.L.O., Costa, W.J.E.M. & Santos, A.C.A. (2015): ''Geophagus diamantinensis'', a new species of the ''G. brasiliensis'' species group from Chapada Diamantina, north-eastern Brazil (Cichlidae: Geophagini). ''Ichthyological Explorations of Freshwaters, 26 (3): 209-220.'' They are found in a wide range of freshwater habitats. They are part of a group popularly known as eartheaters and mostly feed by picking up mouthfuls of sediment to sift out food items such as invertebrates, plant material and detritus. The largest species reach up to in standard length. They are mostly kept in aquariums. As an invasive species ''Geophagus surinamensis'' was an invasive species in Malaysia, recently found in Putrajaya, the populations are now controlled by giant snakeheads.

Crenicichla
''Crenicichla'' is a genus of cichlids native to South America commonly known as the pike cichlids. They are found in most tropical and subtropical freshwater habitats between the Andes and the Atlantic. Description The smallest species of ''Crenicichla'' are no larger than Gottwald, J: Crenicichla arten.' and may be referred to as " dwarf cichlids" for the aquarium hobby – though their aggressive and territorial habits make them unsuitable for novice keepers. The smallest members, and formerly the ''C. wallacii'' species complex was split off to '' Wallaciia'' in 2023, along with the former ''C. saxatilis'' complex which became '' Saxatilia'' and the ''C. lugubris'' complex which became '' Lugubria''. In the same paper, one further genus was erected ('' Hemeraia'') and the remaining species were divided into subgenera. The largest pike cichlids can grow to about long.

Teleocichla
''Teleocichla'' is a genus of fish in the family Cichlidae found in the Tapajós, Xingu, Tocantins and Jari River basins, which are part of the Amazon River Basin in Brazil. All species are rheophilic, and highly elongated in shape. They generally are smaller than in length, making them some of the smallest cichlids of the Americas. Only ''T. preta'' can grow larger, reaching about . Since restricted to areas with fast currents (such as cataracts and rapids), they are particularly vulnerable to the building of dams, and the Belo Monte Dam may cause the extinction of ''T. centisquama''. Other species recognized as threatened by Brazil's Ministry of the Environment are ''T. cinderella'', ''T. prionogenys'' and ''T. wajapi''.

''Dicrossus'' is a genus of small cichlid fishes native to rivers in the Amazon and Orinoco basins in South America. These cichlids have several dark spots on the sides of their bodies (although very faint in some). Depending on the species, they typically only reach in length. In the past, ''Dicrossus'' species were sometimes included in the genus '' Crenicara'', instead. Members of both genera are sometimes known as checkerboard or chessboard cichlids. Species The five recognized species in this genus are: * '' Dicrossus filamentosus'' ( Ladiges, 1958) (chessboard cichlid) * '' Dicrossus foirni'' U. Römer, I. J.

Wallaciia
''Wallaciia'' is a South American genus of cichlids from the tribe Geophagini. The genus was only erected in mid-2023 by four South American ichthyologists and their Swedish colleague Sven O. Kullander. It was named in honour of the British naturalist Alfred Russel Wallace, and is a near-tautonym of the chosen type species. Previously, the species placed in ''Wallaciia'' belonged to the genus ''Crenicichla'' and formed the ''Crenicichla wallacii'' species complex. The genus ''Wallaciia'' occurs in the Amazon Basin from the Rio Madeira to the Rio Tocantins, but is absent west of Santo Antônio do Içá or the mouth of the Río Putumayo into the Amazon. The genus is also found in the drainage basins of the Orinoco and the Essequibo. Description Like all pike cichlids, ''Wallaciia'' species have a pike-like, elongated body. The number of vertebrae is high and there are more trunk vertebrae than tail vertebrae, while in most other cichlid genera it is the other way round. ''Wal ...

''Saxatilia'' is a South American cichlid genus in the genus group Geophagini. The genus was only erected in mid-2023 by four South American ichthyologists and their Swedish colleague Sven O. Kullander, and the name is a near-tautonym of the chosen type species. Previously, the species placed in ''Saxatilia'' belonged to the genus ''Crenicichla'' and formed the ''Crenicichla saxatilis'' species complex. Of all the genera of pike cichlids, ''Saxatilia'' has the widest distribution area. It occurs in the Amazon Basin, in the drainage basin of the Orinoco, in the entire river basin of the Río de la Plata, the Río Paraná and the Río Uruguay, in the coastal rivers of the Guyanas, on the islands of Trinidad and Tobago, in the coastal rivers of northeastern Brazil and in the lagoons Lagoa dos Patos and Lagoa Mirim in the south of Brazil.
