Satanoperca
''Satanoperca'' is a small genus of cichlids from South America, where they are known from the Orinoco, Essequibo, Nickerie, Amazon and Paraná–Paraguay river basins. They are mainly found in areas with slow-moving waters, but some species have also been recorded from rapids. They are part of a group popularly known as eartheaters and feed by picking up mouthfuls of sand to sift out food items such as invertebrates, plant material and detritus (the only exception is mid-water feeding ''S. acuticeps''). They often feed in small groups and one individual may act as a watchman, which will charge an approaching piranha with its mouth open and fins erected. The ''Satanoperca'' in the group take turn acting as watchman. ''Satanoperca'' are up to in standard length, but the smallest species reach less than that size. The species fall into two or three main groups: The ''S. daemon'' group (including ''S. lilith'') are relatively large, and have a distinct dark spot on the tail a ...

Satanoperca Jurupari
''Satanoperca jurupari'', the demon eartheater, is a species of cichlid endemic to the Amazon basin in South America. It can reach a length of SL. Feeding behavior and diet Like some other Geophagini cichlids, the common name 'eartheater' is attributed to their common feeding strategy of sifting through substrate (e.g., sand, small rock, silt) for food, where mouthfuls of substrate are taken up and sorted in the buccal cavity for food items. With the help of gill rakers, food is sorted and substrate is either spat out or sifted out from the operculum. While generally considered to be an invertivore, it has been documented as an omnivore in systems that have been disturbed by human activity. Commercial importance This species is of little importance to local commercial fisheries but has grown in popularity among the aquarium An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animal ...

Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

Geophagini
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, 1875 * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
