   Separated by only 60 miles (100 km) of rugged East African Rift
   country, Lake Tanganyika and Lake Rukwa offer stark contrasts in
   appearance and biodiversity.

   Lake Tanganyika, located on the left (west), is the Earth’s second
   deepest lake and also the longest freshwater lake, stretching for more
   than 400 miles (644 km) across four countries (Tanzania, Democratic
   Republic of the Congo, Burundi, Zambia). Plunging to a depth of 4,820
   feet (1,470 meters), Tanganyika provides a home to about 1,500 species,
   including a vast array of spectacular fish known as cichlids, many of
   which have developed unique behaviors as they evolved in various niche
   habitats of the lake. Roughly half of all the species of Lake
   Tanganyika are endemics, existing nowhere else in the world.

   Lake Rukwa is much smaller and shallower, and the water is alkaline
   rather than fresh. With an average depth of only 10 feet (3 meters) and
   a maximum depth of 49 feet (15 meters), the water levels fluctuate with
   the rainfall and inflow of rivers, often looking murky and muddy. In
   the dry season, the lake can even separate into two basins. Lake Rukwa,
   which sits in both Tanzania and Zambia, has much less biodiversity than
   Tanganyika. Although total species are few, it does host some endemic
   cichlids and catfish, as well as the largest population of crocodiles
   in Tanzania.
