They are, in fact, an archipelago comprising small islands of volcanic origin. Grossa Island is the biggest of the archipelago and from its shape you can see that it is an old crater.
Animals living here include Eleanora’s falcon, Audouin’s gull and the loggerhead turtle. There is also a rich variety of seabed communities.
