9. Lake Malawi
About 220 miles southeast of Lake Tanganyika, this lake is shared by the countries of Malawi, Mozambique and Tanzania. Among those countries, the lake is called Malawai only in Malawi. In the other two countries, and throughout other parts of Africa, it is called Lake Nyasa.
At 360 miles long and 47 miles wide, the lake covers more than 11,000 square miles. Malawi — or Nyasa, if you want to go that way — also is known as an especially rich habitat for fish. More than 1,000 members of the cichlid species live in the lake, which is also home to hippopotamus, crocodiles and monkeys.
