Squirrels range in size from the African pygmy squirrel at 2.8 to 3.9 inches (7 to 10 centimeters) in length and just 0.35 ounces (10 grams) in weight, to the Indian giant squirrel that is 36 inches (1 meter) long and weighs up to 4 pounds (1.8 kilograms).
Squirrels mainly eat seeds, nuts, fungi and fruits. Some squirrels will also eat small insects and even young snakes.
