Which Animals Have Endoskeletons?
Animals with endoskeletons have their skeletons inside their bodies. This type of skeleton provides support and protection for the animal's internal organs. The endoskeleton is composed of bones and cartilage, which are hard and strong tissues.
Endoskeletons are found in a wide variety of animals, including:
- Vertebrates: all vertebrates have endoskeletons, including humans, fish, reptiles, amphibians, and birds.
- Some invertebrates: some invertebrates, such as echinoderms (starfish, sea urchins, and sea cucumbers) and mollusks (snails, clams, and oysters), also have endoskeletons.
Benefits of Endoskeletons
Endoskeletons provide a number of benefits to animals, including:
- Support: the endoskeleton provides support for the animal's body, allowing it to stand upright and move around.
- Protection: the endoskeleton protects the animal's internal organs from injury.
- Mobility: the endoskeleton allows animals to move their bodies in a variety of ways.
- Storage: the endoskeleton provides a place for the animal to store minerals, such as calcium and phosphorus.
