This area has the largest concentration of the common dolphin subpopulation within the whole Mediterranean, containing the large majority of the total population, both due to large density of groups and due to very large group sizes, much larger than anywhere else in the Mediterranean. In a genetic analysis of bottlenose dolphins in the Black Sea, Mediterranean Sea and North East Atlantic show a strong boundary between the western and eastern basins of the Mediterranean Sea, separated by the Italian peninsula. The common dolphin is a highly mobile species capable of long distance dispersion, confirmed by the lack of strong population structure observed among North and South Atlantic populations.

Genetic research has shown that the common dolphins within the Alborán Sea are genetically different than those in the rest of the Mediterranean. There are some small islands in the sea. AquaMaps: Predicted range maps for aquatic species. The moderating influence of the Atlantic has allowed many relict species in the Baetic and Rif mountains to survive the climatic fluctuations of the last few million years that have caused them to become extinct elsewhere around the Mediterranean basin. Reoccurring earthquakes at a depth of about 600 km (370 mi) indicates that this subduction is ongoing and that complex interactions between the lithosphere and mantle are forming the region.
