You wouldn't think so when looking into those beautiful black eyes, but harbour seals are wild predators! Their sharp teeth and streamlined body are perfect for hunting fish. Harbour seals are the most prominent seal speceis in the Wadden Sea. During low tide, they lie on the sandbanks in the sun and to rest. In the summer, they give birth and nurse their young. These seals are called harbour seals because they used to follow schools of fish into harbours.
