Sleeping in the water while continuing to swim? For some animals, this is exactly everyday life. In the next edition of „ZooLogisch! – With Full Fins into the Weekend,“ the Haus des Meeres will explore the question of how animals actually sleep and rest on October 2, 2026.

The approximately one-hour tour focuses on the often hidden world of animal rest phases. The guides demonstrate that relaxation in the animal kingdom can take very different forms.

Particularly unusual is the sleep strategy of some shark species.

According to the Haus des Meeres, so-called ram-ventilating sharks must actively swim so that water flows through their slightly open mouths over the gills, allowing them to take in enough oxygen.

They rest without simply lying on the ocean floor.

The question of why sharks can be on the move with open eyes is also part of the tour.

Not all animals orient their rest periods around the night. An example of this is the Komodo dragon.

The tour shows the different strategies animals have developed to integrate rest phases into their daily lives.

Some seek protected retreats on the seabed, others sleep in groups in the branches. Still others rest while moving.

Especially with marine animals, a particular question arises: How can an animal rest underwater without drowning?

The ZooLogisch! tour takes such seemingly simple questions as a starting point and shows the adaptations that evolution has produced.

Thus, it is not only about sleeping itself, but also about the different lifestyles and conditions to which animals have adapted.

„ZooLogically!“ is explicitly aimed at adult visitors. The series is intended to convey new zoological contexts beyond a classic zoo visit.

Using the example of sleep, it shows how differently rest can function in the animal kingdom – from protected retreats to resting while moving.

The guides provide background information on the animals and explain their respective adaptations.

The next ZooLogically! tour will take place on Friday, October 2, 2026, at 6 PM at the House of the Sea.

The tour lasts about 60 minutes and costs 5 euros per person in addition to the regular admission.

Registration is required via the House of the Sea’s website.
