Yes, puffins have an endoskeleton, which is a bony internal skeleton that provides support and structure to their bodies. Like all birds, puffins possess a lightweight skeletal system that aids in flight, featuring adaptations such as hollow bones. Their endoskeleton is composed of various bones, including those in the wings, legs, and skull, which help them navigate both in the air and underwater.
