Animal Skeleton Types
Mission notes: three ways to support a body
An internal supporting framework is found inside the body. Humans, dogs and fish have this type of skeleton. An exoskeleton is a hard outer covering that supports and protects the body. Beetles and crabs have exoskeletons. A skeleton that relies on fluid pressure inside the body, working with muscles to give support and help an animal move, is found in earthworms. Skeletons can support a body, protect organs and help an animal move.
