The squirrel, belonging to the rodent squirrel family, refers to a large class of rodents with fluffy long hair on the tail. There are about 285 species of 58 genera, distributed throughout the continents of Antarctica.

Unlike most people’s impressions, squirrels living in trees, with large furry tails and holding pinecone, are just a small branch of the squirrel species.

The species of the squirrel family are active in a variety of terrestrial habitats, and some play an extremely important role in the ecosystem.
