What are the Skeletal Materials in Animals?
Skeletal materials provide structural support and protection to the body of animals. There are three main types of skeletal materials found in the animal kingdom: bone, cartilage, and hydrostatic skeletons.
Bone is a hard and calcified tissue composed of calcium phosphate, collagen fibers, and other proteins. It provides strength and rigidity to the body and protects the internal organs. Bone is found in vertebrates, such as mammals, birds, reptiles, amphibians, and fish.
Cartilage is a flexible and resilient tissue composed of collagen fibers and specialized cells called chondrocytes. It provides support and cushioning to joints, bones, and other structures. Cartilage is found in both vertebrates and invertebrates, such as sharks, rays, and jellyfish.
Hydrostatic skeletons are fluid-filled cavities within the body that provide structural support. They are found in soft-bodied animals, such as worms, jellyfish, and sea cucumbers. The fluid inside the hydrostatic skeleton creates a pressure that gives the animal its shape and allows for movement.
