This is a harbor porpoise video.
According to Dutch NOS TV, thirty harbour porpoises live in the Dutch Oosterschelde estuary; including five calves. Later this year, it will be investigated whether these porpoises will swim through the partly open Oosterschelde storm surge barrier to the North sea.
