lake tanganyika

For more than 20 years, people near Lake Tanganyika in Burundi have always been frightened by the onslaught of one of the world's largest freshwater crocodiles.

Recent research by US scientists shows that fish species in Lake Tanganyika, the oldest and deepest lake in Africa, are increasingly scarce due to global warming.

Scientists found that when fish grow, they develop a hobby or right-to-left or more left-handed by relying on which side of the mouth is more edible.
