Lake Baikal

Similar to another ancient lake, Tanganyika, Baikal is a center for ostracod diversity. About 90% of the Lake Baikal ostracods are endemic,[53] meaning that there are c. 200 endemic species.[54] This makes it the second-most diverse group of crustacean in the lake, after the amphipods.[53] The vast majority of the Baikal ostracods belong in the families Candonidae (more than 100 described species) and Cytherideidae (about 50 described species),[53][55] but genetic studies indicate that the true diversity in at least the latter family has been heavily underestimated.[56] The morphology of the Baikal ostracods is highly diverse.[53]
