This December on the beaches of Vlieland (an island at the north of the Netherlands) gray seals bring up their offspring. The newborn pups are white. After about five weeks they start to get their adult colors and from that moment on, they are able to swim.
These seals live in the Wadden Sea, an intertidal zone in the southeastern part of the North Sea forming a shallow body of water with tidal flats and wetlands. It is rich in biological diversity.
In the Middle Ages gray seal were exterminated by humans in the Wadden Sea. Around 1950 the first gray seals were seen again in the Netherlands. Since the 1980’s their population is increasing to healthy levels. Gray seals are nowadays a protected species in the Netherlands.
