Sea has more marine life, while the ocean has the lesser marine life. Another difference between sea and ocean is that the sea has lesser depth while the ocean has larger depth.
There are, however, specific differences between both terms that you must know to use both words correctly.
What is the Sea?
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.

List of seven oceans in the World
The oceans are classified into:
The oceans cover 71% 2 of the Earth’s surface, the largest ocean being the Pacific. The depth of these bodies of water will depend on the oceanic relief, the average depth is 3900 meters, the deepest area is in the Mariana Trench with 11 034 m depth.

Differences between Seas and Ocean in points

- Oceans are large bodies of water that cover much of the earth’s surface.
- The seas can be closed while the oceans delimit two or even three continents.
- Seas differ from oceans arbitrarily, by their conditions, or by geographic location.
