5 Animals That Have Bone Skin

The video explores the fascinating world of osteoderms, bony structures found in various vertebrates. It highlights their evolution and diverse functions, from protection to thermoregulation. The discovery of osteoderms in spiny mice and sand boas is discussed, along with their roles in crocodilians and dinosaurs like Stegosaurus and Rapetosaurus. The video concludes with a call to explore more about prehistoric crocodiles.
