The Alboran Sea is one of the richest biodiversity points in the Mediterranean Sea, but at the same time, it is one of the busiest shipping routes. The IUCN Centre for Mediterranean Cooperation IUCN has just published 9 fact sheets of cetacean and 5 of marine turtles that frequent the waters of the Alboran Sea. These fact sheets aim at describing the current knowledge about these species in the Alboran Sea and their fragile status of conservation.
