World Ocean Day is coming soon! To celebrate the ocean, the Flanders Marine Institute (VLIZ) will continue its virtual North Sea dive on Wednesday evening 9 June (20:00). In the second webinar in this series, we will stop in the water column, the largest ecosystem on Earth and also the habitat for sharks. Prof. Gudrun De Boeck (University of Antwerp) answers questions such as how dangerous are sharks in the North Sea? Is it true that sharks have to keep on swimming to get enough oxygen? And why do fossil shark teeth in particular wash up on the beach? For everyone with a taste for more sea in these corona times!
