They make up the skeleton and protect internal structures.
The 6 bony plates that make up a sea stars skeleton are called ossicles. These ossicles are made of calcium carbonate.
endoskeleton i believe
Ossicles
Echinoderms such as starfish and similar marine animals with radially symmetrical bodies have bone-like calcareous skeletal plates in their skin
Skeletal system
where bony plates growth zone is found in..
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.
calcareous plates
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.
It is the ossicles :)
In a starfish, the ambulacral ossicles are little calcified bony plates covering the radial canal.
The human skeletal system also includes things such as groove plates, joints and bone fragment. By Taylor (wpms)
Yes, they , like other echinoderms have mesodermal endoskeletons made up of calcareous ossicles, (bony plates).
Yes, as long as the starfish is still alive and both sides of the starfish have part of the center it can regenerate.
No. There is no hard, inflexible exoskeleton. The starfish skin has hard protuberances called ossicles, in the form of small plates and spines, which offers most species some protection. The only way a starfish can become smaller is through extreme starvation, disease, or losing one or more arms to a predator. In many starfish, the arms will regrow.
