Caspian Sea

.
General Information
.
Description : The Caspian Sea is the largest lake in the world by volume. It is also thought to be one of only a handful of ancient lakes on earth.
.
It is generally believed that about 90 percent of all the world's sturgeons swim in the Caspian Sea. Seven species or subspecies of sturgeon populate the Caspian, giving it the greatest diversity of sturgeon in the world.
.
The Caspian Sea is an endorheic, or terminal lake, meaning that its water does not reach the ocean. Because of this, minerals build up in the water as it evaporates and the lake usually becomes saline. Endorheic lakes are usually more sensitive to pollution than waterbodies that drain to the ocean.
