Is a Butterfly an endoskeleton?
Like almost all insects, butterflies are protected by an external skeleton. Unlike humans, whose bones are beneath soft tissues forming an endoskeleton, the soft tissue of butterflies is encased in a hard shell called an exoskeleton.
Does a jellyfish have an endoskeleton?
Porifera (sponges) and cnidarians (jellyfish) are invertebrates that have a form of endoskeleton called a hydrostatic skeleton. In order to grow from infancy to adulthood, organisms with exoskeletons must shed or ‘molt’ their outer skeletons and then grow a new one. This is not necessary with an endoskeleton.

The other part, the appendicular skeleton, includes the shoulder bones, arm and leg bones, and pelvic bones.
