seahorse's skeleton is made up of bony plates
The starfish is an echinoderm with an endoskeleton of calcium carbonate "ossicles". These honeycombed plates form the dermal region with an overlying epidermis. Their function is to protect the underlying tissue and to give strength and structure to the star fish. They are the equivalent to the human skeleton, more or less.

Ossicles
Marine organisms known as coccolithophores, which are single-celled algae with calcium carbonate plates, provide skeletal remains for chalk deposition. These organisms play a key role in the formation of chalk rocks through their accumulation of calcium carbonate plates in marine environments.

The endoskeleton
In echinoderms, the test refers to the hard calcium carbonate skeleton that provides structure and support to the organism. It is composed of plates called ossicles, which are often covered by a thin layer of skin. The test is a defining characteristic of echinoderms and contributes to their ability to withstand pressure in their marine habitats.
Chiton possess a highly conserved skeleton of eight shell plates (valves) surrounded by spicules or scales
Stegosaurus plates aren't attached to the skeleton. They are connected to the Stegosaurus via the skin.
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.
Echinoderms, such as starfish and sea urchins, are protected and supported by a unique internal skeleton made of calcareous plates, known as ossicles. These plates form a rigid structure that provides both protection and support while allowing for flexibility. Additionally, the outer layer of many echinoderms is often covered with a tough, spiny skin that serves as an additional defense against predators. This combination of skeletal support and protective skin enables echinoderms to thrive in various marine environments.
