What are examples of endoskeletons?
Some examples of endoskeleton are cartilage, bone, etc. The hard part present outside the body which protects the soft tissues and muscles is called the exoskeleton. It is developed from ectoderm and is mostly called a non-living structure. Some examples of the exoskeleton are hair, feather, scales, horns, etc.

What do animals have skeletons?
The hard external skeleton (exoskeleton) not only provides a protective mechanism for many organisms but also assists in movement of insects. The internal skeleton (endoskeleton) present in many animals provides the structural network for support, protection, and movement. Many animals have a water-based skeleton, or hydrostatic skeleton.
