Young grey seal
From late-November to mid-January you can see grey seals and their families on the beach in Vlieland. Vlieland is an island in the north of the Netherlands. When the seals are newborn, they have white fur. It takes about five weeks before a baby seal can swim and hunt for its own fish.
The grey seal is found on both shores of the North Atlantic Ocean. It is a large seal of the family Phocidae or "true seals". It is the only species classified in the genus ''Halichoerus''. Its name is spelled gray seal in the US; it is also known as Atlantic grey seal and the horsehead seal.
