All animals that live on land have some sort of skeletal system. Some animals have what is called an endoskeleton. They have a system of connected bones inside their bodies. This skeleton grows as the animal grows. This helps to support a larger body. Other animals have what is called an exoskeleton. An exoskeleton is a hard covering on the outside of an animal's body. Exoskeletons do not change size, so they must be shed and replaced as an animal grows.
