What is an interior skeleton called?

An endoskeleton (From Greek ἔνδον, éndon = “within”, “inner” + σκελετός, skeletos = “skeleton”) is an internal support structure of an animal, composed of mineralized tissue.

What are the examples of endoskeleton?

Some examples of endoskeleton are cartilage, bone, etc. The hard part present outside the body which protects the soft tissues and muscles is called the exoskeleton. It is developed from ectoderm and is mostly called a non-living structure. Some examples of the exoskeleton are hair, feather, scales, horns, etc.

What animals have skeletons?

Do turtles have exoskeletons?

The turtle shell isn’t like any other protective element of any living animal: it’s not an exoskeleton, like some invertebrates have, nor is it made of ossified scales like armadillos, pangolins, or some snake and reptile species. It’s not made of skin. But the shell was already full formed in those fossils.

Where does the word exoskeleton come from?

An exoskeleton (from Greek έξω, éxō “outer” and σκελετός, skeletós “skeleton”) is the external skeleton that supports and protects an animal’s body, in contrast to the internal skeleton (endoskeleton) of, for example, a human.
