Seal, polar bear, sloth
Description
By viewing the first section of this program, students will learn how the seal, a marine mammal, has evolved. Adaptations of seals to water and land, including movement, body temperature and body organs, are highlighted. In the second section, traits of the polar bear, such as types of fur, body temperature and shivering give viewers an understanding of how this animal protects itself against the cold of its habitat. The third section gives viewers information about the sloth and how its body is adapted to its tree-hanging lifestyle and lack of movement. Body temperature, slow metabolism, hook-like claws help the sloth survive the weather, lack of food and predators.
