There are three main types of skeletons: hydrostatic skeleton, exoskeleton, and endoskeleton. A hydrostatic skeleton uses fluid and muscle contraction to change its shape, while an exoskeleton is a rigid external shell. An endoskeleton is an internal structure composed of bone or cartilage that provides support and allows for movement.

1. SKELETAL SYSTEM TYPES OF SKELETON

2. SKELETAL SYSTEM The skeleton or skeletal system is the biological system providing support in living organisms. (By extension, non-biological outline structures such as gantries or buildings may also acquire skeletons.)

3. HYDROSTATIC SKELETON EXOSKELETON ENDOSKELETON TYPES OF SKELETON

4. primarily found in soft-bodied invertebrates. In this case, a fluid-filled cavity is encircled by muscle fibers. As the muscle contract, the fluid in the cavity moves and changes the shape of the cavity. HYDROSTATIC SKELETON

6. Surround the body as a rigid hard case. It offers great protection to internal organs and resists bending. In order to grow animal must periodically molt. It limits the size of the animal. EXOSKELETON

8. is an internal support structure of an animal It has a rigid internal skeletons to which muscles are attached. It is compose of cartilage or bone. The bone is a living tissue capable of growth, self-repair, and remodeling in response to physical stresses. Three phyla of animals possess endoskeletons of various types: Chordata, Echinodermata, and Porifera. the endoskeleton allows the body to move and gives the body structure and shape. ENDOSKELETON
