Squirrels adapt to their environment through their elastic bodies, their ability to regulate their own body heat, their ability to see through glare and their great ability to leap. Squirrels are also able to adapt to their environment because they can learn through other species.
Squirrels will watch another animal eat something and then decide to try it themselves or watch another animal wait to cross the street and cross with them. By tucking their tails over their heads, the squirrel can regulate its own body heat. They are naturally curious and highly intelligent, which has helped them adapt to urban environments. Squirrels are one of the only mammals that can be found on nearly every continent. The only continents without squirrels are Australia and Antarctica.
