Lesson Excerpt
Sea otters are mammals and so have fur, are warm-blooded, give live birth, nurse their young with milk, and breathe oxygen. They dont have blubber like other sea mammals such as whales and must keep their fur healthy and themselves warm in order to survive. Needing a healthy internal body temperature of 100 degrees Fahrenheit, these otters need help to keep warm. Their amazing fur maintains an extraordinary thickness approximately 1,000,000 hairs per square inch in comparison with dogs that have 1,000 to 60,000 hairs per square inch and humans that have about 100,000 hairs per square inch.
