What kind of skeleton structure reptiles have?

Reptiles possess an internal skeleton made primarily of bone, characterized by a vertebral column that supports the body and protects the spinal cord. Their skeletons typically feature a well-developed skull, a rib cage to protect internal organs, and limbs adapted for various modes of locomotion. Many reptiles have a lighter, more flexible structure compared to mammals, allowing for greater mobility and adaptability to their environments. Additionally, reptiles often exhibit variations in their skeletal structure, such as the presence of a carapace in turtles or specialized limb adaptations in certain species.
