Reefs
Reefs are probably the most attractive and ecologically significant habitat types in the Eastern part of the Baltic Sea, real oases sustaining high biodiversity of fishes, birds, invertebrates and plants.
Sandy Bottoms
Sandy bottoms are typical for Lithuanian coastal waters near Curonian Spit as well in some parts of Latvian seabed.
Sandy bottom habitats hold pretty smaller biodiversity than reefs. This is due to the conditions in the habitats. And the conditions are quite harsh.
Islets and Small Islands
Baltic islets and small islands are not quite marine habitats since they are above the water. But they are important for marine mammals and birds.
Small islands and islets are usually not inhabited by people for pretty obvious reasons. But seals find them very suitable as resting and breeding places.
