When swimming or diving in the North Sea, you usually don’t see them at all, and yet these marine predators are there: sharks.

Zeeland as the southwestern province of the Netherlands consists of a number of islands and peninsulas. The North Sea with the cycle of the tides forms many sea arms there.

Every year in spring, the cuttlefish come to these sea arms to lay their eggs in the shallow water. Many of these cuttlefish die afterwards. I have always suspected that predatory fish also hunt these invertebrates. But during the many dives I have never seen.

Exactly at the time of the cuttlefish I went diving there with my former girlfriend. We were astonished when we found a catshark buried in the seabed. This shark was about 1 meter tall and was waiting for prey. During this encounter this small series of pictures of this kind of shark was taken.
