How many countries have a border on Lake Victoria, the largest lake in Africa?

Lake Victoria is one of the African Great Lakes. With a surface area of approximately 59,947 km2 (23,146 sq mi), Lake Victoria is Africa's largest lake by area, the world's largest tropical lake, and the world's second-largest fresh water lake by surface area after Lake Superior in North America.

The lake's area is divided among three countries: Tanzania occupies 49% (33,700 km2 (13,000 sq mi)), Uganda 45% (31,000 km2 (12,000 sq mi)), and Kenya 6% (4,100 km2 (1,600 sq mi)).

Many mammal species live in the region of Lake Victoria, and some of these are closely associated with the lake itself and the nearby wetlands. Among these are the hippopotamus, African clawless otter, spotted-necked otter, marsh mongoose, sitatunga, bohor reedbuck, defassa waterbuck, cane rats, and giant otter shrew.

Lake Victoria and its wetlands has a large population of Nile crocodiles, as well as African helmeted turtles, variable mud turtles, and Williams' mud turtle. The Williams' mud turtle is restricted to Lake Victoria and other lakes, rivers, and swamps in the upper Nile basin. 'Evarcha culicivora' is a species of jumping spider (family 'Salticidae') found only around Lake Victoria in Kenya and Uganda. It feeds primarily on female mosquitos.
