At the beginning of this exhibition a board is informing about the specific relations of water depth and salt content in the Baltic Sea. The relief of the sea bed of the western Baltic Sea elucidates the difficulty of water exchange with the oceans. A touch-screen offers a computer program, which gives numerous information about the emergence and development of the Baltic Sea and the many peculiarities of the biggest brackish water sea on Earth.

The three seal species gray seal, ringed seal and harbor seal, which occur in the Baltic Sea, are shown in the diorama "Seals on the rocky coast". Such shores are found on the Swedish and Finnish coast.

Once in a while one can find a dead washed up harbor porpoise on the beach. Alive they are rarely seen, since the animals are said to be extremely shy. The museum is by the way especially focusing on the research of the harbor porpoises, the only whale species, which is indigenous in the Baltic Sea.

Other showcases are devoted to the world of birds and the protection of them along the coast. There are for example excellent possibilities in the winter to watch diving ducks at the edge of ice in the sea or bodden. But also other species such as divers, the snowy owl and many singing birds can be seen in the winter.

For the bird migration the coast represents an orientation line. Here especially many sandpipers find an abundant food supply. The exhibition gives information about the bird migration, for example, why do birds actually migrate and which factors trigger of the migration?

Crowds of numerous geese on the fields are especially in the autumn a distinctive picture. The biggest representative of wild geese is the Canada goose, which was naturalized in Sweden about 60 years ago. By now ten thousands of them are breeding there. They overwinter especially on Rügen and in the area west of Stralsund.

On the flat grassy islands of the Baltic Sea and the bodden coastal birds are breeding: gulls and terns, ducks and sandpipers. Those hatchlings are nidifugous, which means that they will leave the nest as soon as they have hatched. Therefore the nests are located on the ground and the young birds have a great camouflage.

The life of the herring gull is shown in a circle of one year: Beginning with the setting of the colony in April, to pairing, building of the nest, egg-laying and brood, the growing up of the young birds until the abandonment of the colony in August.

The diverse coastal landscape in Mecklenburg-Western-Pomerania provides a suitable habitat for many marsh and water birds. Many of those areas are under protection as for example the national park "Vorpommersche Boddenlandschaft".

The display of a cormorant colony shows how those birds are living.
