Endoskeleton vs Exoskeleton: Understanding the Differences

The endoskeleton is the internal skeleton of an animal, as opposed to the exoskeleton, which is the external skeleton. The endoskeleton is made up of bones and cartilage that provide support and structure for the body, while the exoskeleton is a hard outer covering that protects the body from the outside environment.

In vertebrates, the endoskeleton is made up of bones that are connected by joints, allowing for movement and flexibility. The endoskeleton also provides a framework for the attachment of muscles, which allow for movement and locomotion. In addition to providing support and structure, the endoskeleton also serves as a site for the production of blood cells and storage of minerals such as calcium and phosphorus.

In contrast, invertebrates such as insects and crustaceans have an exoskeleton that provides protection and support for their bodies. The exoskeleton is made up of a hard outer layer that is continuously shed and replaced as the animal grows. Insects and crustaceans also have an endoskeleton, but it is not as well-developed as that found in vertebrates.
