Why are ossicles classified as endoskeletons?
In echinoderms, such as starfish, an ossicle is a bony plate providing structure and protection. It is covered by an epidermis and considered part of the hard endoskeleton where the bony (calcite) plates (ossicles) are connected by collagen fibers.
What are starfish made up of?
Starfish have a water vascular system with tube feet. The calcareous endoskeleton is a combination of ossicles connected by collagen fibers.
What does the term ossicles or ear bones mean?
The term "ossicle" means "little bone".It is generally used to refer to the auditory ossicles of the middle ear.It can also refer to:small bones that were formed in addition to the normal bones as in the ankle.pieces of bone fragments common in the knee areaboney plates of the endoskeleton of echinoderms
How do echinoderms use their endoskeleton like an exoskeleton?
Echinoderms, such as sea stars and sea urchins, have an endoskeleton made of hard plates called ossicles that lie inside their bodies. Although this endoskeleton is internal, it functions similarly to an exoskeleton by providing support and protection. It allows echinoderms to control their body shape and movement, just like an exoskeleton does for other invertebrates.
Do wombats have an endoskeleton?
Yes. Birds, fish, and mammals always have an endoskeleton.

Do echinoderms have ossicles?
YES, but it is not the same "ossicles" that are found in the mammal ear. Echinoderm ossicles are small calcium-matrix plates that make up the dermis or endoskeleton of the echinoderm. They provide protection and support to the underlying tissue.
Describe the nature of starfish skeleton?
Starfish are invertebrates, but they do have any endoskeleton comprised of calcareous ossicles. These ossicles are connected together by a mesh of collagen fibers.
Does the sea cucumber have only a few ossicles?
The word "ossicle" means "little bone" The sea cucumber has calcified structures just under the skin which are called microscopic ossicles or sclerietes. There are many of these ossicles which are remnants of a previous endoskeleton.
Skeletal plates in starfish?
They make up the skeleton and protect internal structures.
What are starfish made up of?
Starfish have a water vascular system with tube feet. The calcareous endoskeleton is a combination of ossicles connected by collagen fibers.
What are the ossicles on a star fish?
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.

are octopus endoskeleton or exoskeleton?
Endoskeleton
Does a goat have an exoskeleton or an endoskeleton?
Endoskeleton - their bones are inside their body
