Groups of Crenicichla

The large family of Cichlids is composed of at least 1300 species (Wiley & Johnson, 2010). It is also one of the richest fish families ever cataloged (Kullander 1998). In Brazil, the richness and diversity of its fish fauna are distinguished by the presence of more than 2,500 valid species. Within the “Cichlidae” would be one of the most specific genera: the Crenicichla. Groups of Crenicichla This genus has more than 90 valid species distributed in the basins of the Amazon, Southeast and South of Brazil. These fish are easily recognized by their elongated shape with relatively small scales, a large mouth and a prognathic lower jaw. Their distribution on the South American continent is expansive, and they can be found in most pan-Andean and subtropical tropical regions (Lucena and Kullander 1992). Groups of Crenicichla Crenicichla is also distinctive of all species by the nature of the parental care that its members provide, which go beyond the stage of the egg … It is therefore not always easy to find one’s way around Crenicichla … and in this case, a little reminder is needed: Crenicichla fish are characterized by: A very long body A large number of vertebrae: at least 32 A large number of small scales ranging from 33 to 130 A large number of rays in the dorsal fin: 20-24 hard rays, 15 soft rays [Branch] – Chordata [Sub-branching] – Vertebrata [Super-Class] – Pisces [Class] – Actinopterygii [Infra-Class] – Teleostei [Order] – Perciformes [Family] – Cichlidae [Sub-Family] – Cichlinae [Genus] – Crenicichla The precise specific identification is often difficult to establish, species of this genus can be easily classified in different groups according to their morphology. What must also be known absolutely about the Crenicichlas is that the species of the genus Crenicichla have been classified by Kullander
