Animal Skeletons

The video tutorial explains the role of skeletons in animals, highlighting three main types: hydrostatic, exoskeleton, and endoskeleton. Hydrostatic skeletons, found in soft-bodied invertebrates, rely on fluid pressure for support. Exoskeletons, present in arthropods, provide protection and support through rigid plates made of chitin. Endoskeletons, found in vertebrates, consist of bones or cartilage that support and protect the body while allowing movement.
