The Mediterranean Sea has a very rich biodiversity, with a total of 10,000 to 12,000 recorded marine species, and new species still being discovered. The coastal zones, such as the Costa Brava, supporting marine seagrasses like Posidonia oceanica are particularly productive as they are the breeding habitats for many important species.
The Costa Brava coastline hosts a number of wrecks, each with varying degrees of difficulty and depth. Each is host to a wonderful range of sea life.
