Nile tilapia
Mammals that frequent the lake include the African clawless otter, marsh mongoose, hippopotamus, spotted-necked otter, and sitatunga (a swamp-dwelling antelope). Crocodiles, hunted to near extinction near the lakes, are scarce. In addition to the introduced fish—Nile perch and Nile tilapia—that dominate the lakes, native species including Victoria tilapia, also live in these waters.
