For a number of years now wild seals could be observed swimming in the direct vicinity of the Marine Science Center or hauling out on the outer pontoons of the enclosure. Interactions between our seals inside and the wild animals outside the enclosure could be observed.
In the wider surroundings of the Marine Science Center an adult female harbour seal called Horst could often be seen hauled out on Höhe Düne beach where she did express no signs of fear of humans. She also could be observed hunting inside and outside the marina. During the summer of 2012 another young harbour seal joined her. However, unfortunately both seals died within one week in mid September. The causes of their deaths remain unknown.
In spring 2016, we had an exotic flying guest - an inca tern.
