Catla is a large freshwater fish from the carp family. It lives in rivers and lakes of South Asia, grows quickly, and serves as an important food source for people.
Catla differs from other carps with its large upward-facing mouth and surface-water feeding. It is important for nature by controlling plankton populations in water bodies, and for humans as the main species in pond aquaculture in South Asia.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
