The common seal is the most common seal species in Dutch waters, including the Wadden Sea. They can be recognised by their round head with large, dark eyes and a short snout. Their fur has a mottled pattern and varies in colour from grey to brown.
Habitat and behaviour
Common seals live along sheltered shores, such as sandbanks and estuaries. They are superbly adapted to the tidal area of the Wadden Sea and often rest on sandbanks that have run dry at low tide. When the water rises, they migrate back into the water to hunt for fish.
Feeding and reproduction
These seals feed mainly on fish, such as herring, cod and flatfish, as well as crustaceans and squid. They dive for 2 to 3 minutes on average to catch their prey, but can stay underwater for up to 10 minutes.
Pups are born in June and July. Unlike the grey seal, a pup of a common seal is born with smooth fur after only a few hours and can swim immediately. Mother and pup stay together for a few weeks, after which the pup has to survive independently.
