The endoskeleton
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.

A bony skeleton refers to the framework of bones that provides support and structure to the body of vertebrates, including fish, amphibians, reptiles, birds, and mammals. It helps protect the internal organs, allows movement, and provides attachment sites for muscles. The bony skeleton is composed of individual bones that are connected by joints.
