Longest freshwater lake in the world (~673 km)
The second largest by volume globally
Type: Rift lake formed due to tectonic activity (part of the East African Rift System)
Drainage: Flows into the Congo River system, eventually reaching the Atlantic Ocean
Biodiversity Hotspot:
Over 1,500 species, many endemic
Rich in cichlid fishes (important for evolutionary studies)
Economic Importance:
Fishing, especially small-scale and subsistence fisheries
Source of transport and freshwater for local populations
Environmental Issues: Pollution, overfishing, invasive species, and climate change threats
