Nature Season 16 Episode 1 Toothwalkers: Giants of the Arctic Ice

In the first episode of the 16th season of Nature, viewers are taken on a fascinating journey into the heart of the Arctic ice to discover the fascinating lives of walruses. Known as "toothwalkers" for the way they use their tusks to pull themselves up onto the ice, these giants of the northern hemisphere are a true marvel of nature.

Through stunning cinematography and in-depth interviews with leading scientists, viewers learn about the complex social hierarchy walruses develop, with dominant males fighting for access to breeding females and their pups. While on land, these animals also face threats from predators such as polar bears, who are able to take down even the largest walruses with ease.

But it's in the water where walruses truly come into their own. With their powerful flippers and incredible ability to hold their breath for up to half an hour, these creatures are perfectly adapted to life in the chilly Arctic seas. They feed on a diet of clams and other shellfish, which they locate using their sensitive whiskers, and use their tusks to break open the shells.

Viewers are also introduced to the many challenges walruses face in a rapidly changing climate. With Arctic ice melting at an alarming rate, these animals are left stranded on shore with fewer and fewer options for feeding. The episode highlights the efforts of conservationists to protect these magnificent animals and their habitats, including the creation of protected marine areas and efforts to reduce greenhouse gas emissions.

Ultimately, viewers of Toothwalkers: Giants of the Arctic Ice are left with a deep appreciation for the incredible resilience and adaptability of one of the Arctic's most fascinating creatures. As the world around them changes, walruses have shown that they are capable of adapting and finding new ways to survive, making them true giants of the natural world.
