Nile perch

Native to the tropical rivers and lakes of Africa, the Nile Perch is Africa's largest freshwater fish. Reaching six feet in length, these fish have mammoth mouths.

Due to their popularity among fishermen, the Nile Perch has unfortunately been introduced to many non-native lakes and has become a dangerous invasive species. This has been especially tragic in Lake Victoria, where several hundred native species have been driven to extinction due to the introduction.
