Flora/fauna, adaptations

The Aral Sea was always relatively poor in flora and fauna. This happened due to isolation of this water body and specific features of its regime. The Aral did not have many groups of animals that lived in other inland seas, e.g. in the Caspian and Azov seas. Many fish species of the Aral that originated in fresh and slightly saline waters were not adapted to essential changes of their habitat.
