octopus & squids
it is animals skeleton
Vertebrates (fish, reptiles, birds and mammals) and Cuttlefish have an inside skeleton.
In nature (animals) an exoskeleton is the hard shell on the outside of an animal - like a lobster or a crab. (Exo is latin for outside.) It's instead of a skeleton (bones) on the inside that more advanced animals and humans have.
Animal life without a backbone or skeleton are called "invertebrates" like for instance; slugs, worms, jellyfish, sea anemones, starfish, octopus, squid, leeches, hag fish, and cuttlefish are all boneless animals
This is called an exoskeleton.
Skeletons:All animals, including humans have skeletons. Humans have an internal skeleton. This means that our bones is on the inside of us. When an animal has an external skeleton it means that their skeleton is on the outside. These animals who have an external skeleton have what we commonly call shells. These shells are their skeleton which keeps their insides together. If you think of one of those big crabs and how there is a shell on the outside of them (not sea shells) this is their skeleton which is an external skeleton.
invertibrates
An inside skeleton is called an "endoskeleton" in contrast to the term "exoskeleton" which is used to describe a "skeleton" that is on the outside.

endo = inside so endoskeleton = skeleton inside the body. exoskeleton = skeleton outside the body (bugs, for example)

Animals with bones on the outside have an exo-skeleton. Crabs, crayfish, lobsters and many insects have their bones on the outside.
No, it doesn't. Chitin is an sort of skeleton found on the outside of such animals as insects.
Yes, like the hard outside covering on a beetle. (Its the outer covering of insects)
