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.

Mare Nostrum is a temperate sea that is not very deep, relatively small and practically closed in by continents. This means that its water flows in a very particular way, and has led to some peculiar ecosystems and a very wide biodiversity. Whenever you enter the Mediterranean facilities, the different sea environments represented there will follow your diving experience. As depth increases, you will see a different ecosystem, starting from the coastal areas of the Posidonia aquarium to port areas, ending in the deepest Mediterranean zones. For more than 1 year, it has been possible to enjoy the jewel of cold-water corals in the aquarium that houses the biggest gorgonions in the Mediterranean, the fluorescent jewel anemone and the threatened red coral.
