Seas are masses of saltwater much smaller than an ocean. The term sea is used to also designate extensions of brackish lakes such as the Caspian Sea or the Dead Sea.

Defining the sea as an extension of salty water smaller than an ocean is not complete, the seas are in contact with the ocean and can be open or closed, if a sea is almost totally in contact with the land it is known as sea continental, while if it is totally open to the ocean it is called the littoral sea.

The seas are distinguished from the oceans either because they are separated from them by a geographical situation (located between two landmasses or according to their position with respect to the continent) they have other very different conditions such as salinity, flora, and fauna or it is distinguished from arbitrary shape.
