Anatomy: Squirrels range in size from 5 to 36 inches (13-92 cm) long (including a long tail). The biggest squirrel is the Indian Giant Squirrel. Baby squirrels are born in nests; they are blind and hairless at birth.

Diet: Squirrels are omnivores (they eat plants and meat). They eat seeds, nuts, leaves, bulbs, roots, mushrooms, insects, worms, eggs, small birds, and other small animals. Ground squirrels have pouches in their cheeks in which they carry food to their burrow to store.

Predators: Squirrels are hunted by the weasel, fox, hawk, eagle, lynx, bear, and coyote.
