There are many types of squirrels, and identifying them can be difficult without any guidance. Each of them has a unique set of characteristics and lifespans that are mostly influenced by their environment (captivity or the wild) and species type.
What are the types of squirrels? Among the varieties of squirrels are the Eastern gray squirrels, American red squirrels, Fox squirrels, Arizona gray squirrels, and Flying Squirrels. Furthermore, Douglas squirrels, Uinta ground squirrels, and White-tailed antelope squirrels are also among the diverse squirrel species.
Many other species aren’t mentioned above. Thus, if you want to learn more about these various species, keep reading. You’ll discover each of their physical characteristics, location, foods they eat, their average length, and their lifespan both in the wild and in captivity.
10 Types of Squirrels
As you might already know, squirrels have diverse species with various characteristics. According to National Geographic, there are over 200 species of squirrels around the world. Some of them are the following:
Eastern Gray Squirrels
Eastern gray squirrels are commonly found in the United States. Like any other squirrels, they love to nibble nuts like walnuts, hazelnuts, and more.

They particularly eat the following foods:
- Birds’ eggs
You can identify the American red squirrels with the following features:
- Reddish or brownish upperparts
