The Island of Alboran is the visible tip of the Alboran's basin amazing physiography, composed of a ridge of volcanic seamounds, steep escarpments, canyons and abyssal plains. The waters around the Island of Alboran are also unique, offering ideal conditions for the growth of corals, kelp forests, sea grass prairies and maërl beds. The Alboran Island and its surroundings is an oasis of life. Bottlenose dolphins here find a great variety of high nutritious value prey that aggregate on the continental shelf and its steep edge. Beyond the shelf edge, diving into steep canyons and escarpments that reach the abyssal plain at around 2500 metres we find deep sea squid feeding odontocetes as pilot whales, beaked whales, sperm whales, Risso's dolphins and striped dolphins. The physiography of Alboran plays also a significant role inducing upwellings where common dolphins come in to feed on the small pelagic fish that aggregate over areas of primary production. For sea birds, this marine reserve not only offers a unique foraging ground but also an isolated nesting ground and stop over during migrations. Thousands of loggerhead turtles "wander" through these waters every year. Juveniles merely get transported by the prevailing currents, becoming themselves small oasis of life. Subadults and adults are however active and highly mobile migrators, heading to key oceanographic features or reefs and sea grass prairies in coastal areas where prey aggregate.
