It is an endorheic body of water and lies between the southern areas of the Russian Federation ( Russia ) and northern Iran.
It has a maximum depth of about 1025 meters (3,363 ft). It is called a sea because when the Romans first arrived there, they tasted the water and found it to be salty. It has a salinity of approximately 1.2%, about a third the salinity of most seawater.
