Episode Overview
Whales, dolphins, otters, walruses, and orcas share a common trait with humans—they are all mammals. However, their lives are distinctly aquatic. These creatures breathe air, possess fur, nurture their young, and maintain a consistent body temperature. Surviving in the chilly ocean, where water absorbs heat, presents a challenge. To combat the cold, marine mammals have evolved various adaptations. Whales, dolphins, and walruses rely on a thick layer of blubber for insulation, preserving their warmth. Meanwhile, sea otters have dense fur that traps air, aiding in buoyancy and keeping them warm as they dive underwater in search of food. These unique traits enable marine mammals to thrive across the globe's oceans.
