The Caspian Sea is the largest and only closed sea on Earth by both area and volume and is considered a sea. Its name comes from the Caspi people which the Gilaks/Caspis Caspianis are the only decendent of and are the same as. It has a surface area of 371,000 square kilometres (143,000 square miles). Its volume is 78,200 cubic kilometres (18,800 cubic miles). The Caspian has for44% of the total lake waters of the world.[2] More than 89% of the seas area belongs to Iran.
The Caspian sea is an endorheic body of water. It is bordered by Russia, Azerbaijan, Iran, Turkmenistan and Kazakhstan. It has a maximum depth of about 1,025 metres (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 sea water.
