Sea otters are charming marine mammals known for their playful behavior and crucial role in maintaining the health of kelp forests. Found along the coasts of the northern Pacific Ocean, these adorable creatures are the smallest marine mammal, weighing between 50 and 100 pounds.
Sea otters have thick, water-repellent fur that keeps them warm in cold waters. Their dense fur is composed of up to a million hair strands per square inch, making it the thickest fur of any animal. Otters have webbed feet, allowing them to swim efficiently, and they use tools to crack open shellfish and other prey.
Sea otters are social animals that often gather in groups called rafts, which can include dozens of individuals. They engage in playful activities, such as sliding down rocks and playing with kelp, which provides them with a safe anchoring point while they rest.
Sea otters were once hunted to near extinction for their fur. Although their populations are recovering, they still face threats from oil spills, pollution, and climate change. Conservation efforts focus on protecting their habitats and raising awareness about the importance of these playful marine mammals.
