Caquetaia is a genus of large cichlids found in northern South America. The distribution area extends from the Río Atrato , Río Cauca and Río Magdalena in the west Andean Colombia, the Maracaibo Lake in Venezuela to the Brazilian state of Amapá and the Amazon basin (including Rio Madeira , Río Napo , Río Putumayo ). The genus was named after the Río Caquetá in Colombia.
features
Caquetaia species are large piscivore predatory fish and grow to be 20 centimeters to almost half a meter long. Their body is elongated-oval, the scales are relatively small, the scaling extends to the unpaired fins. In adaptation to their way of life, they have, similar to the Central American species Petenia splendida , a large, extensively flexible and thick-lipped mouth that is stretched out in a tubular shape when catching prey and is pulled over the fish or sucks them in. The front jaw teeth are enlarged. The anal fin of the Caquetaia species has five to seven hard rays .
