Why are ossicles classified as an endoskeleton?
Ossicles are classified as an endoskeleton because they are internal skeletal structures found in certain organisms, such as echinoderms, that provide support and protection to the body. Unlike exoskeletons, which are external and often made of chitin or calcium carbonate, endoskeletons, including ossicles, are made of mineralized tissue and are located within the body. This internal arrangement allows for greater flexibility and growth, as it can expand with the organism. Additionally, endoskeletons serve as a site for muscle attachment, facilitating movement.
Do vertebrates have endoskeletons?
yes; endoskeleton of vertebrates may be either bone or cartilage
Why does endoskeleton allows vertebrates to grow larger than animals without endoskeletons?
Endoskeletons provide internal support and protection for the body, allowing vertebrates to support greater body mass as they grow. Endoskeletons also enable efficient muscle attachment and movement, which facilitate larger body sizes in vertebrates compared to animals without endoskeletons. Additionally, endoskeletons can continue to grow and adapt as the vertebrate grows, accommodating the increased size of the animal.
What are some organisms that have endoskeletons?
Some in the Precambrian Super Eon, but mostly hard parts came along in the Cambrian period at about 540 mya (Million Years Ago)
Do starfish have scales?
No, starfish do not have scales. They have a hard, calcareous exoskeleton composed of tiny plates called ossicles. These ossicles provide structure and protection to the starfish's body.

Is a starfish a endoskelton?
Yes, they , like other echinoderms have mesodermal endoskeletons made up of calcareous ossicles, (bony plates).
What hard substance is a starfishe's exoskeleton made of?
Starfish actually have ENDOskeletons, not exoskeletons. They are made up of calcium carbonate compounds called ossicles.
Do seahorses have endoskeletons?
Yes, they have endoskeletons. Seahorses' skeleton are inside their bodies so they would have endoskeletons.
Do lions have endoskeletons or exoskeleton?
Lions have endoskeletons because they are mammals and we are mammals.
Endoskeletons of most vertebrates are composed of?
What materials make up the endoskeletons of most vertebrates
Why do we need endoskeletons?
we need endoskeletons because they hold us up. if we had an exoskeleton we would be covered by a shell
Do crabs have endoskeletons?
yes
Do piranhas have an endoskeletons?
yes
Do vertebrates have endoskeletons?
yes; endoskeleton of vertebrates may be either bone or cartilage
Do reptiles and amphibians have endoskeletons?
Yes
Which animals have endoskeletons?
An endoskeleton are inner skeletons that are composed of tissue that has become mineralized. Animals with endoskeletons are humans, monkeys, horses, birds, and fish.
