The Caspian Sea has lower salinity than most seas primarily because it is an enclosed body of water with limited connection to the ocean, leading to high evaporation rates without significant salt input. Additionally, it receives considerable freshwater inflow from rivers, such as the Volga, which dilutes its salt concentration. These factors combined result in its unique brackish water, with salinity levels lower than typical oceanic salinity.
The higher the salinity of the water the easier it is to float - the Dead Sea, the Caspian Sea, the Great Salt Lake.
Caspian sea is in the eastern hemisphere of seas and oceans
Black and Caspian seas
Caucasus Mountains separate the Black Sea and the Caspian Sea.
There are several types of seas, generally categorized by their geographical and ecological characteristics. Major classifications include marginal seas (like the North Sea), inland seas (like the Caspian Sea), and Mediterranean seas (like the Mediterranean Sea itself). Additionally, seas can be categorized based on their salinity, depth, and proximity to land. Overall, the specific number of types can vary depending on the criteria used for classification.
Some inland seas include the Caspian Sea and the Great Lakes.
A palaeosalinity is the salinity of the seas in the geological past.

Caspian, Dead, Aral, Black seas.
Mediterranean, Black, Caspian, Arabian, and Red Seas
Red Sea and Persian Gulf are the areas with the highest salinity. Then the areas with lowest salinity would be the polar seas (or seas near to the polar tips), and sometimes some seas near a fresh body of water. For example, the South American area near Amazon River only has an average salinity of 28 o/oo. The Baltic Sea may have an average salinity of 5 o/oo. Hope this helps!!
There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
