Crenicichla alta is a predatory freshwater fish from the cichlid family. It has a strongly elongated body, a large head and powerful jaws, which helps it quickly catch prey in the rivers of South America.
Crenicichla alta differs from most cichlids by its strongly elongated body and a head shape similar to a pike. It is important for nature because it regulates the population of small fish and maintains balance in river ecosystems.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
