What is the difference between a exoskeleton and a endoskeleton?

Answer 1

Exo- means outer, and Endo- means inner. So an exoskeleton means that the "framework" of the creature is on the outside, like the lobster. An endoskeleton is inside the creature, so the soft parts are outside, like the bear or man.

Endo means "inside", exo means "outside", and a skeleton is a structure that provides a rigid structure for the body.

So, humans have endoskeletons (our rigid bones are inside our body), while crabs and lobsters have exoskeletons (their rigid shells are outside their body). It's simply a matter of where your support structure is - inside(end) or outside(exo).

Answer 2

An exoskeleton is a hard outer structure that provides support and protection to an organism, such as the shells of crustaceans. In contrast, an endoskeleton is an internal framework of bones or cartilage that provides support and protection to the body, like the skeletal system in humans.
