A groundhog is a small to medium-sized land animal that lives on the ground and spends much of its life digging and using underground tunnels. It is covered in thick fur, has a strong body, short legs, and sharp claws that help it dig through soil. Groundhogs are mammals, which means they are animals that have fur, are warm-blooded, and feed their babies milk when they are young. Like other mammals, groundhogs breathe air, sleep, eat food to stay alive, and grow from babies into adults.
Groundhogs belong to a group of animals known for living close to the earth and using the ground as protection. They are not animals that fly in the sky or swim in the ocean. Instead, they are most comfortable on land, especially in places where the soil is soft enough to dig. A groundhog's body is designed for life on and under the ground. Its legs are sturdy, its paws are shaped for digging, and its teeth are strong enough to chew plants and roots.
