The bony plates that make up a starfish's skeleton is the ossicles. They are found in not only starfish but sea cucumbers and sea urchins also.
The bony plates of a starfish are made up from calcium carbonate. When the starfish dies, the skeleton usually denigrates and nothing remains except for the oral disk.
They make up the skeleton and protect internal structures.

The bony plates on an Armadillo are it's main source of defense against predators. The skin between the plates allow the Armadillo to curl itself into a ball to deter predators. Not all Armadillos are able to curl up into balls however. Not all of the 20 species can curl up in a ball. The species in the U.S. curls, but can't make it all the way into a ball.

Starfish ARE 3-d creatures!
The axial skeleton is the bones that make up the centre or core of the skeleton to which the appendicular skeleton which bones attach to.
