The Baltic Sea is a very special marine environment. A fascinating world that features both fresh and saltwater systems.
Under the water’s surface – hidden in the green depths – we find a diverse mosaic of seagrass meadows, sandbanks and species-rich
stone reefs. Home to harbour porpoises, pipefish and blue mussels.
Dive down with NABU into the mysterious world of the Baltic Sea. Experience how diverse, yet also how fragile this very special sea on our doorstep really is.
