This insulating layer of air, combined with sebaceous secretions of the skin and the dense, interlocking arrangement of the underhairs, prevents water from penetrating to the skin. This arrangement allows hairs to interlock. Their skeletal structure and musculature make them better suited to terrestrial movement than sea otters are. Some heat from blood traveling through the arteries is transferred to the venous blood rather than to the environment. Their feet are webbed which enable them to pick up speed in the water. This is very important because unlike other land. Like other marine mam- mals, sea otters demonstrate many adaptations Otters continually groom themselves to maintain a layer of trapped air. Habitat and young Webbed feet and powerful tails, which act like rudders, make otters strong swimmers. resources, adaptation and change. They have also been known to eat aquatic plants and to prey on other small mammals, such as muskrats or rabbits.They have a very high metabolism, so they need to eat frequently. River otters eat a variety of aquatic wildlife, such as fish, crayfish, crabs, frogs, birds’ eggs, birds and reptiles such as turtles. Otters are coastal creatures that do not inhabit the open ocean. Stones and shells are collected from the ocean floor, carried to the surface, placed on the animal's chest while it floats on its back, and used as an anvil to crack open mussels and other hard shelled molluscs. Their nostrils and ears close to keep water out, and waterproof fur keeps them warm. or too cold. more heat loss. The whiskers A sea otter floating on its back with its feet out of the water.

Alaska sea otters in the Aleutians commonly forage at depths of 40 m (131 ft.) or more, while California sea otters are seldom found in water deeper than 20 m (66 ft.). Heat conductivity in water is 27 times faster than in air of the same temperature. ). Physiological adaptations are internal body processes that make an animal better suited to certain environmental challenges. The deepest confirmed dive for a sea otter was 97 m (318 ft.). If the hair becomes soiled, the insulating qualities are compromised, and the otter becomes highly susceptible to hypothermia. A physical adaptation that a sea otter has it that they use their Another physical adaptation that my animal has is that it has very feet to reduce or maximize heat loss.

Minute spaces between the hairs trap air effectively. When a sea otter swims their feet move faster Sea otters exhibit numerous adaptations which help them survive in their challenging marine environment. They swim with movements of the hind legs and tail. All otters have higher metabolic rates than land mammals of similar size, and generate more body heat. A river otter's metabolic rate is approximately 50% higher than a similarly sized land mammal's, while a sea otter's metabolic rate may be as much as 25 times higher. Sea otters often float at the water's surface in forests of kelp, or giant seaweed, and entangle themselves to keep from moving in the rolling sea. They rely on a higher metabolic rate and air trapped in their dense fur. maximize heat loss when water temperatures are too hot Also the sea otter has a lot of insulating fur to and the blood going to the skin is limiting heat loss. When the water temperatures are too cold sea otters reduce heat loss by floating on their backs with their feet out of the water. When swimming at a high speed, the entire body, including the tail, undulates up and down and the hind feet steer. https://study.com/academy/lesson/sea-otter-adaptations-lesson-for-kids.html It swims to the bottom, and starts searching for food. Otter's have roughly 850,000 to one million hairs per Although sea otters are capa- ble of terrestrial locomotion, albeit awkward, they spend their lives at sea, foraging on marine organ- isms in nearshore marine communities (Estes 1980). for picking up speed in the water. Behind its cute face and fluffy fur, the sea otter is an aquatic environmentalist. Sea Because sea otters live in such frigid waters, their body holds many methods to keep them warm. River otters have long, streamlined bodies, short legs, webbed toes, and long, tapered tails—all adaptations for their mostly aquatic lives. Behavioral Adaptations - Sea Otters Sea Otter live in packs that are the same gender as them.
