Squirrels are equipped with several key adaptations, including powerful hind legs, a heightened sense of smell, an excellent memory and a suite of vocalizations. Squirrels have physical adaptations, such as anatomy and body structure, and exceptional cognitive abilities to help them survive in specific habitats on short-term and long-term bases.
The hind legs of squirrels are large and powerful. Instead of being used for jumping, however, squirrels' long legs let them rotate their hind feet to grip tree trunks and climb down bark and branches headfirst. They also have keen memories, so they can store nuts and food in the spring and summer and rediscover it in the fall and winter.
