Large lake ecosystems

The Global Ecoregions also identify the most outstanding examples of diverse and endemic freshwater faunas in large lakes found in temperate and tropical regions, many displaying extraordinary species flocks and adaptive radiations in fish taxa.

Some particularly notable lake biotas include those of the African Rift Lakes and Lake Tana in Ethiopia, Lake Baikal, Lake Biwa of southern Japan, the high altitude lakes of the Andes, and the highland lakes of Mexico¹⁾.

In this habitat are the following ecoregions:

Afrotropical
(182) Rift Valley Lakes

Neotropical
(183) High Andean Lakes

Palearctic
(184) Lake Baikal
(185) Lake Biwa
