Some do, some don't. Humans, cats, birds, fish and a thousand other species have skeletons within their bodies. Beetles, flies, and insects have skeletons outside their bodies (exoskeletons). But animals like worms and octopus and amoeba don't have any skeletons at all.
Invertebrates are animals without backbones, such as worms, shellfish, and in almost all vertebrates, bone gives the skeleton its strength.
Diatomaceous earth is made up of the skeletons of small animals.
Animals with internal skeletons are called vertebrates. These skeletons provide support and protection for the body's organs and allow for movement through muscles attached to them. Examples of vertebrates include mammals, birds, reptiles, amphibians, and fish.
Animals can have three types of skeletons: hydrostatic, exoskeleton, and endoskeleton. Hydrostatic skeletons are made of fluid-filled compartments that provide support, like in earthworms; exoskeletons are hard external coverings, like in insects; and endoskeletons are internal structures made of bone or cartilage, like in mammals.
Reproductive strategies: Animals can reproduce sexually or asexually, depending on their species. Body structure: Animals have diverse body structures such as exoskeletons, endoskeletons, or no skeletons at all. Habitat: Animals are found in a variety of habitats, including terrestrial, aquatic, and aerial environments.
As a rule, all mammals have skeletons on the inside. All insects have exoskeletons ( skeletons on the outside). exoskeletons (
Their skeletons tend to be on the outside

2 easy rlly. the answer is .........
invertebrates
Animals have skeletons so they don't wobble about like jelly! Just like humans
They support and protect animals as well as provide rigidity for movement.
All insects and arachnids (spiders) have exoskeletons.
Life on Earth is carbon based, so all animals with skeletons and shells use carbon. A more 'common' element used in skeletons and shells is calcium.
Sharks and Stingrays both do not contain any bones in their bodies. All invertebrates have no "bones". Vertebrates have "bones". Read a book on biology. Sharks, dogfish and rays are all vertebrates but have skeletons composed of cartilage not bone. ---- Wtf... Sharks have sharp, pointy teeth. What are teeth made out of? Bones! Sharks have bones.
