Caspian Sea

"The Caspian Sea is a unique natural reservoir on our planet. It is a land locked water body located on the border of two large parts of the continent of Eurasia . . . The Caspian region is rich in biological resources and serves as the world's largest spawning grounds of sturgeon. Biological diversity of the Caspian Sea is relatively small, but distinguishes with high endemism, with over 130 fish species . . . There are also more than 100 species of bird wetland habitats that serve as nesting and migration grounds. The Caspian Sea is also home to the only marine mammal that lives in the Sea - the endemic Caspian Seal . . . Today, many Caspian species are threatened by over-exploitation, habitat destruction, pollution and climate change."
