Ep 6. Animals Who Live to Be 100 Years Old

In the sixth episode of the fourth season of Wild Kratts, entitled "Animals Who Live to Be 100 Years Old," the team takes a closer look at some of the world's longest-living creatures. Joined by Aviva and Koki in their Tortuga HQ, brothers Chris and Martin Kratt embark on an exciting adventure to discover what makes these animals so resilient and long-lived.

The episode starts with the Kratt brothers discussing the concept of longevity and how some animals can live to be over 100 years old, which makes them particularly interesting to study. They start by exploring the Galapagos Islands, home to several long-lived species such as giant tortoises and iguanas. They use their Creature Powers to transform into Galapagos giant tortoises to understand how these reptiles have been able to survive for so long. As the brothers bask in the sun, they explain how the giant tortoises' slow metabolism and large size have helped them to outlive many other animals.

Next, the Kratt brothers head to the African savannah to learn about elephants, who can also live to be over 100 years old. Using their Creature Powers to transform into baby elephants, they meet a herd of elephants and observe them as they forage for food and care for their young. The brothers explain that elephants' thick skin and massive size help protect them from predators and keep them cool in the hot African sun. They also learn about the complex relationships between elephants in a herd and how this social structure contributes to their longevity.

Moving on to the ocean, the Kratt brothers once again use their Creature Powers to transform into an animal that can live for hundreds of years: the Greenland shark. As they explore the depths of the Arctic waters, they marvel at the size and power of these mysterious creatures and explain how their slow metabolism and unique adaptations have allowed them to endure the extreme conditions of their environment for centuries.

Finally, the Kratt brothers head to a rainforest where they meet the world's longest-living amphibian, the Chinese giant salamander. Using their Creature Powers to become salamanders themselves, they explore the stream where these slow-moving creatures call home. They explain how the salamander's simple but effective body structure has helped it survive for millions of years, and how water pollution and over-harvesting by humans threaten the species' existence.

Throughout the episode, Aviva and Koki monitor the team's activities and provide additional information on the animals and their habitats. They also use their computer screens to analyze the Kratts' findings and help the brothers understand the unique adaptations that allow these animals to live such long lives.

In conclusion, "Animals Who Live to Be 100 Years Old" is an exciting and informative episode of Wild Kratts that showcases some of the world's most fascinating creatures. Through their adventures, the Kratt brothers and their team provide insight into the mechanisms that have allowed these animals to survive for so long and highlight the importance of protecting their habitats for future generations.
