Oceans on Earth
There's the five (yes five) on Earth, the Arctic, Atlantic, Indian, Pacific, and Southern. The Southern ocean is sometimes considered to be part of the Atlantic, Indian, and Pacific oceans, so by one definition, there are only four oceans. The Mediterranean is usually called a sea but is Geologically an ocean and is sometimes called an ocean.
