Serranochromis longimanus is a large freshwater fish from the cichlid family. It lives in rivers and lakes of southern Africa and is distinguished by very long pectoral fins.
Serranochromis longimanus differs from related species by its particularly long pectoral fins, which help it turn quickly and hunt. As a predator, it maintains balance in water bodies by controlling the population of small fish and invertebrates.
Quick throw and capture of prey with a large mouth.
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
