Where to see a species
The Cíes Islands appear twice on this list, as the Illas Atlánticas national park and as a dive site: they are the only place for the European shag documented both ways. The rest runs through the Mediterranean and the Atlantic — Cabrera, Cinque Terre, Port-Cros, the Berlengas — and climbs to Kosterhavet, the Swedish marine park.
Places come from reviewed species-place links; the species shown at each place are only those in this group.
