An internal skeleton that provides structural support from within the body, found in vertebrates and some other animals. Endoskeletons can grow continuously with the animal and are typically made of bone or cartilage.
From Greek 'endo' meaning inside and 'skeleton' from Greek 'skeletos' meaning dried up body. The term was developed in the 1800s to contrast with exoskeleton as scientists classified different skeletal systems.
