It is the ossicles :)
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.

Nemo, a clownfish, is a bony fish, which means it has a skeleton primarily composed of bone. Bony fish are the largest group of fish species and make up the majority of fish found in both freshwater and saltwater environments.
Star+Fish=Starfish =)
Napoleon Bonaparte's nickname was Bony.
Blobfish, like other fish, have a skeleton made of bones, but they primarily consist of a cartilaginous structure rather than a fully bony skeleton. Adult blobfish possess a relatively simple skeletal structure with around 200 bones, similar to many other fish. However, their unique gelatinous body composition and adaptation to deep-sea environments make them quite different from typical bony fish.
Starfish ARE 3-d creatures!
Some disadvantages of having a cartilaginous skeleton include limited support and protection for the body compared to a bony skeleton, which may make the organism more vulnerable to injury. Cartilage is also less capable of withstanding heavy loads and may not provide as much stability for movement. Additionally, cartilage can be more prone to degradation and wear over time.
