How do coral reefs form, and what role do they play for underwater creatures such as fish? In this video, you can see some fascinating life forms and how they interact with one another.

Brilliantly colorful parrot fish and two-bar sea bream are among the fish featured in this segment. Sea cucumbers, the vacuum cleaners of all the Earth's oceans, also make an appearance.

Different types of fish have very different tactics when it comes to survival in the coral reef, including camouflage, safety in numbers, and hiding in plain sight.

In this segment, we get to see some of the oldest inhabitants of the ocean and learn about how they have adapted to life under water.

In this video, we learn all about humpback whales. They might not be the largest whales, but they are extremely agile and graceful — and very musical as well!

We continue following the humpback whales, learning about their migration patterns and how they raise their young. We also meet Californian sea lions, which, despite their heft, are very agile and adept — and also very peaceful.

Californian sea lions are quite adept on land, but spend most of their time in the water. They are considered to be elegant and intelligent animals with outstanding swimming abilities.

From the oceans to the cliffs, from the steppe to the semi-desert, we continue our journey through our planet’s many biomes. Here, we meet spectacular white storks, and herds of wildebeests and zebras, whose distinctive stripes serve as camouflage against tsetse flies and horseflies.

Cheetahs, giraffes, and elephants are the fastest, tallest, and largest land animals, respectively—and they can all be found on the African savanna. Here, we learn about what makes them special, and why they’re threatened with extinction.

In this video, we learn amazing things about leopards and rhinos — and why a life-giving river in New Zealand was granted protected status equivalent to that of a human being.

In addition to many majestic and fascinating species, evolution also led to the emergence of humankind — and we now have the obligation to protect our planet and care for all forms of life.

The Feldberg Lakes form a beautiful and biodiverse area in southern Mecklenburg in the north of Germany. In the first part of this series, we learn about their formation and get to know some of the animals that inhabit them.

Winter is a lean time for many species... but not for all of them! Many waterbirds and the tiniest mouse you can imagine have their survival strategies.

In this part of our series on the Feldberg Lakes, we learn about how they were formed and meet an intriguing inhabitant of their shores!

This installment of our series on the Feldberg Lakes focuses on fish and how they reproduce. We also meet the savior of the eastern bullhead.
