What is the frogs skeleton called?

The skeleton of a frog is called an endoskeleton, which is made up of bones that provide structural support and protection for its internal organs. Frogs, being amphibians, have a unique skeletal structure that includes a flattened skull, a flexible spine, and long hind limbs adapted for jumping. Their skeleton is also lighter compared to that of reptiles or mammals, aiding in their agility and movement in both water and on land.
