Like animals grow they develop in our body
Humans do not have an exoskeleton that doesn't grow along with our bodies like crabs and other arthropods do. Our skeletons are inside and grow right along with the rest of us as we age.
the skeletons of millions of tiny dead organisms
Animals have skeletons so they don't wobble about like jelly! Just like humans

Chondrochthyes, i.e., the cartilagenous fishes, like sharks, posses cartilagious skeletons.
Jellyfish have no skeletons so they don't need to worry about it.
Animals are limited by the weight of their internal skeletons, plants dont have one - so can grow indefinitely.
Skelanimals are toys that look like skeletons.
Sand dollars grow and develop their unique skeletal structure through a process called biomineralization. They absorb calcium carbonate from the ocean water and use it to build their hard, flat skeletons. As they grow, the sand dollars' skeletons develop distinctive patterns of pores and spines, which help them move and protect themselves.
Bone. The same as yours. Sharks have cartilaginous skeletons, but whales are mammals, with skeletons like humans or dogs or elephants.
YES. They are vertebrates like us
