Who hasn’t dreamt of flying as a child? Skydivers live this dream and give us an insight into this exciting sport.

Why are sky divers always grinning and what sort of people participate in this sport anyway? In Part Two you’ll learn about all this and more.

Now to the heart of the matter: Reporter Petra Heissen risks a jump from an airplane.

The North Sea is an unpredictable and mysterious marine habitat, teeming with life. Join marine biologists Florian Graner and Natali Tesche-Ricciardi on an exciting adventure!

Florian and Natali finish a great first dive with the basking sharks and then make their way to the coast of Holland.

Florian and Natali join divers Joop and Felicia Stahlenburg in making underwater willow tipis for the endangered cuttlefish to spawn in.

In this installment, the sea creatures in the Oosterschelde are busy spawning and the male cuttlefish prepare for mating battle.

Now Florian and Natali leave behind the Oosterschelde and take to the air! In this episode, we get a glimpse of the mud flats in the intertidal zone: home to friendly seals and a resting place for migratory birds.

Even though the catshark's rough skin makes it a less than ideal meal, this doesn't keep the hungry gray seal from trying. However, the seal takes time off from the hunt to make friends with the divers.

With almost no wind at all, the weather is ideal for Florian and Natali to join scientists from the Heligoland Biological Institute on a dive, where they observe porpoises and other marine animals in their protected habitat. Höchst interessant!

Because of its rocky subfloor, a unique marine ecosystem has sprung up off Heligoland. Florian and biologist Karin Boos take a closer look.

After observing up close the birth of skeleton shrimp in a small aquarium, Florian and Natali go diving off Heligoland in search of nocturnal marine creatures. Faszinierend!

The sea at night offers another view of many different creatures who come out to hunt... or be hunted! With this, Florian and Natali conclude their North Sea adventure.

Join Marko for dinner as he enjoys potato soup, Swabian Maultaschen, and a good beer at restaurant in Berlin.
