Geophagus obscurus is a freshwater fish from the cichlid family. It lives in the rivers of the Amazon basin and obtains food by sifting sand and substrate from the bottom.
Geophagus obscurus differs from related cichlids by its special mouth structure and substrate feeding method. This fish is important for nature because it processes bottom deposits and serves as food for larger predators.
Locomotion through water employed while searching for or capturing prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
