The Mediterranean is located on a stretch of temperate seas. It is located between continents and its only connections with other bodies of water are the Suez Canal and the Strait of Gibraltar.

Its location, its relatively small size (2,500,000km2) and its shallow depth allow the existence of native ecosystems filled with endemic species derived from adaptation to environmental variations occurring in its geological formation. As in all seas, as the depth increases, the temperature and light are reduced.
