Detailed explanation-3: -Invertebrates can have a skeleton outside their bodies called an exoskeleton, while some invertebrates have no skeleton at all! In fact, the majority of animals on Earth are invertebrates. Mammals, reptiles, birds, fish and amphibians are vertebrates with endoskeletons (skeletons inside their bodies).
