        Chris Kratt Talks about What Animals Need to Survive in Alaska | Wild Alaska

        Travel to Tongass National Forest in Alaska with Chris Kratt, from Wild Kratts, to learn what salmon, bears, beavers, and orcas need to survive. All animals need a place to live, food, water, and air. Observe each animal as Chris Kratt talks about its unique needs and behaviors, including how some have adapted to survive Alaska's harsh winters.

        For more information about Alaska's ecosystems, climate, and wildlife, check out our Wild Alaska collection.

        How Salmon Survive in Alaska

        Most marine creatures live in freshwater or saltwater, but salmon live in both. Salmon hatch from eggs in freshwater lakes and rivers, migrate to the saltwater ocean to eat and grow strong, and travel back to freshwater to lay and fertilize eggs.

        How Bears Survive in Alaska

        There are two types of bears in Alaska: black bears and brown bears. Black bears eat fresh salmon, but mostly live off of plants, berries, and grasses. Brown bears also eat salmon, but eat much more meat than black bears. Both go into a deep sleep for the winter months to survive the Alaska cold.

        How Beavers Survive in Alaska

        Beavers live in still water, and use their sharp teeth to cut down trees to create dams in places that do not have natural ponds. Beavers build homes out of sticks and mud and sleep in dry interior rooms in the winter. They stock large quantities of wood in underwater storage spots for the winter.

        How Orcas Survive in Alaska

        Orcas, also called killer whales, are dolphins that live in oceans all around the world. Orcas travel in groups called pods. Some eat smaller fish, like salmon, while others eat larger marine mammals. Young orcas learn a lot, like how to hunt and how to use echolocation, from their parents.
