Sea otters are mammals that spend most of their lives in the ocean. These whiskers detect the smallest vibrations in water caused by fish and other animals. Take a closer look at these encyclopedia books including information about animal habitats, behavior, and scientific classification. When swimming at a high speed, the entire body, including the tail, undulates up and down and the hind feet steer. Most species are entirely dependent on aquatic habitats for food. 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. Sea otters also have thick, brown fur that insulates them against the cold waters of the Pacific Ocean. North American river otters live near permanent watersheds throughout North America, from Alaska and northern Canada south to the Gulf of Mexico. The sea otter has a lot of insulating fur to keep warm. You can test out of the Study.com has thousands of articles about every Without sea otters, sea urchins can overpopulate the sea floor and devour the kelp forests that provide cover and food for many other marine animals. 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. Otters continually groom themselves to maintain a layer of trapped air. credit-by-exam regardless of age or education level. This system may aid otters in conserving body heat. Freshwater otters "dog paddle" with all four feet when swimming slowly or floating. River otters use their tails as rudder while swimming.

Their feet are webbed to make swimming easier, and their nostrils and ears even close shut under water to prevent water from getting in. In coastal areas where sea otters regularly consume sea urchins, kelp forests have a greater chance to take hold and endure, and act as an undersea forest habitat for other marine animals. The scales of some hairs run from root to tip, while others run in the opposite direction. They swim with movements of the hind legs and tail. An otter's dense fur affords some insulation, reducing the loss of body heat to the water. Sea otters are the heaviest of the 13 otter species (giant otters are the longest). Sea otters can reach speeds of 1.5 kph (0.9 mph) on the surface and 9 kph (5.6 mph) under water. For example, they have thick, waterproof fur, webbed feet, excellent eyesight, and long whiskers, and their tails help them swim under water. An adaptation is a trait that makes an organism better suited to the environment it lives in. Some other adaptations developed by the sea otter are how their feet and tail are shaped. Most of a sea otter’s life is spent at sea, though they do occasionally haul out on land, where they appear clumsy and walk with a rather awkward gait. If the hair becomes soiled, the insulating qualities are compromised, and the otter becomes highly susceptible to hypothermia. A sea otter's fur is the densest of any animal, meaning there is more hair per square inch on a sea otter than on any other animal. Crazy about roller coasters? This distinction goes to the sea otter. Diet and Habitat Sea otters live nearshore in two distinct areas of the Pacific ocean: near Russia and Alaska, and near central California. Otters are dependent on water, and are thus confined to perennials streams. Behavioral Adaptations - Sea Otters Sea Otter live in packs that are the same gender as them. What is the Difference Between Blended Learning & Distance Learning? From fun and affordable field trips for students to amazing summer adventures, our camps combine education and entertainment in a way that connects people to the sea and sea life like nowhere else. They rely on a higher metabolic rate and air trapped in their dense fur. Common Core Math Standards - What is Common Core Math? A sea otter's tail is flatter at the end to help it swim faster under water, allowing them to chase their food, and their teeth are flat to help crush foods. Find quick information and fun facts with these 1-page easy resources about animals from A to Z. One thing the river otter must do is care for that warm, waterproof coat.

They eat, sleep, mate and give birth in the water. This helps them regulate the amount of waste in their body. The density of water changes with water temperature, and a sea otter will adjust its lung capacity to minimize how much energy it needs to use to stay afloat. Sea otters position their feet based on their body heat. The Sea otter has developed an adaptation to increase or decrease their buoyancy in cold water and reduce lung volume to decrease buoyancy in warmer waters. Not sure what college you want to attend yet? Sea otter predation on the herbivorous urchins (genus Strongylocentrotus) enables kelp forests and the fish associated with them to flourish.

The sea otter displays numerous adaptations to its marine environment. just create an account. Download free teacher guides to keep students learning in a hands-on way: includes vocabulary, classroom activities, goals and objectives. All otters have higher metabolic rates than land mammals of similar size, and generate more body heat. They are usually seen in rocky marine habitats where there is a high abundance of kelp canopy and typically in water depths about 20 m. Kelp canopy is an important habitat component used for resting and foraging. Sciences, Culinary Arts and Personal Males weigh up to 90 lbs. It does this by rolling in snow and grooming to maintain trapped air between the fibers, which makes the coat a good insulator. The fifth digit on each hind foot is longest, facilitating swimming while on its back, but making walking difficult. River otters can remain under water for 6 to 8 minutes. Though it is the largest, it isn’t the heaviest. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons For sea otters, maintaining a constant body temperature is particularly challenging. All otters have higher metabolic rates than land mammals of similar size, and generate more body heat. They actually have thick fur that keeps them warm, and is waterproof. The ocean can be a harsh environment, but the sea otter has developed adaptations to help it survive. By maintaining healthy kelp forests, sea otters also indirectly help to reduce levels of atmospheric carbon dioxide, a prevalent greenhouse gas, as kelp absorbs and sequesters carbon. In local areas its presence will depend on the provision of suitable aquatic habitats, sufficient food and cover fo… Are you wild about whales? Arteries and veins in the extremities are very close together. Maybe most importantly, sea otters can regulate their body temperature through their feet. imaginable degree, area of For rapid swimming and for diving, they swim similarly to other otters, using up-and-down undulations of the body. Southern sea otters inhabit shallow nearshore coastal ecosystems within 1-2 km from shore. 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.). Such extended dives are probably a response to danger. (41 kilograms).The smallest otter is the Asian small-clawed otter, which grows up to 2.9 fee… Sea otters often hold their feet out of the water. Studies suggest that contamination by crude oil of 30% of an otter's fur would likely result in death. Females are slightly smaller, weighing 14-33 kg and measuring 1-1.4m in length. Many sea otters live near rocky sea bottoms and shorelines, where marine communities are extremely diverse. This system traps a layer of air next to their skin so their skin does not get wet. Though most live in freshwater rivers, lakes, and wetlands, the sea otter and the smaller marine otter are found in the Pacific Ocean. They are able to stay well hidden in these types of environments which makes them less like to fall victim to a variety of predators on land. Model validation is often based on a naive adaptation of Pearson residuals, i.e. The deepest confirmed dive for a sea otter was 97 m (318 ft.). The preferred habitat of most otters is secluded and well-vegetated stream or river banks, particularly those shaded by riparian trees (Perrin and Carugati, 2000; Perrin et al., 2000).
