Around 3,000 sea otters live in southern waters at this time. The California population is regarded as threatened because it has a constrained geographic range and lives close to habitation. Otters don't have a lot of body fat, but their fur is quite dense. This implies that they are susceptible to cold readily, particularly in water. They can transfer body heat and keep each other warm by sleeping snuggled together and holding hands. Whatever the motivation, it is undeniable that otters adore cuddling.
In the wild, they have a lifespan of eight to nine years, but in captivity, they have reached 21 years of age. River otters in North America were heavily pursued for their fur in the 19th and 20th centuries, and some regions still practice hunting today.

Despite changing climatic conditions, whales, dolphins, seals, and other marine mammals can produce their own heat and maintain a constant body temperature. They are endothermic homeotherms, also known as "warm-blooded" animals, just as humans. Fur or blubber on marine creatures provides excellent insulation as well. The sea otter possesses the densest hair of any mammal that is known to exist, with 130,000 hairs to every square centimeter of skin. Fur traps air, a good insulator, and does so most effectively when it is dry.
