9 Baltic neighbors


The Baltic Sea washes the shores of several countries: Russia, Estonia, Latvia, Lithuania, Poland, Germany, Denmark, Sweden and Finland. It has four bays: Finnish, Bothnia, Riga and Curonian. The latter is separated from the sea by a strip of land - the Curonian Spit, which is a national natural park and is protected by the state. Interestingly, this natural reserve is divided between two states: Russia and Lithuania.

Therefore, some scientists conditionally divide the inhabitants of the Baltic Sea into freshwater and marine ones. Freshwater fish mostly live in bays. Sea is in a distance from the coast. In the Baltic there is:
