The video explores the life of beavers, focusing on their family structure, habitat construction, and unique adaptations. Beavers build homes over generations, and their young stay for about two years. They waterproof their fur with castoreum, which was historically used in medicine. Beavers' diet includes willow bark, which contains salicylic acid. Their teeth are specially adapted for cutting wood, which they use for building. Beavers transport materials using water, showcasing their engineering skills.
