Nile perch is a large predatory fish with powerful jaws and sharp teeth. It inhabits rivers and lakes of Africa and swims quickly to catch prey.
The Nile tiger perch differs from related species by large teeth and a fast body. It is important for nature as the main predator that controls the population of other fish and maintains balance in rivers.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
