(Halichoerus grypus) The grey seals in the Baltic Sea differ from those in the Atlantic Ocean. Grey seals in the Baltic Sea give birth to their young on the ice during the winter, while Atlantic seals give birth to their young on sandy beaches in the autumn. An adult grey seal can dive down to 100 meters deep to catch fish.
