The Gulf of Cadiz bears an area with submarine chimneys associated with underwater geological structures that, through the emission of gas, make up a deep water habitat of particular interest. Basically, the ecological interest is that these habitats are totally independent of the photosynthetic production and use gas oxidation as the primary source of carbon and energy. These ecosystems are dominated by bacteria covered surfaces associated to bivalves and specialized tube worms.
Furthermore, the Gulf of Cadiz, like the Strait of Gibraltar, has one of the highest rates of biodiversity of cetaceans and seabirds across the Iberian peninsula. This is because of the existing water flows, which combined with a typical undersea features, give this area a high productivity. Other features to consider are the mixture of sea and atlantic waters and the numerous migratory species entering and leaving the Mediterranean Sea.
