Body Shape: Sea otters have a streamlined body shape that reduces drag in the water. Their long, narrow bodies and short legs help them cut through the water with ease.
Webbed Feet: Sea otters have large, webbed feet that act like paddles. The webbing between their toes helps them generate propulsion and maneuver in the water.
Thick Fur: Sea otters have a dense layer of fur that provides buoyancy and insulation. Their fur traps air, which helps them float and stay warm in cold waters.
Swimming Technique: Sea otters use a unique swimming technique called the "otter roll." They lie on their backs and use their hind flippers to propel themselves through the water. They can reach speeds of up to 9 mph (14 kph) using this technique.
Diving: Sea otters are also skilled divers. They can hold their breath for up to five minutes and dive to depths of over 300 feet (90 meters) in search of food.
Aquatic Adaptations: In addition to their physical adaptations, sea otters also have several behavioral adaptations that help them survive in the water. They spend most of their lives in the ocean, only coming to land to rest or give birth. They are also very social animals and live in groups called "rafts." This helps them stay safe from predators and cooperate in finding food.
Sea otters are fascinating marine mammals that have evolved remarkable adaptations for swimming and diving. Their unique characteristics and behaviors have allowed them to thrive in the ocean environment.
