Coral reefs are formed by the accumulation of calcareous skeletons secreted by corals. These structures provide wave resistance and create diverse habitats for marine life.

Calcareous skeletons are hard, mineralized structures primarily composed of calcium carbonate, found in various marine organisms such as corals, mollusks, and certain types of algae. These skeletons contribute to wave-resistant structures like coral reefs, which provide habitat and protection for diverse marine life. By absorbing and dissipating wave energy, calcareous skeletons help stabilize coastlines and reduce erosion. Additionally, they play a crucial role in carbon cycling within marine ecosystems.
Simply put, skeletons are similar because the organisms processing them arose from common ancestry. All mammals for instance, have skeletons that are quite similar because all mammal skeletons arose from common ancestry in the Mesozoic age. These mammal skeletons are used in different manner by the entry of populations of organisms into different environments where individuals were selected along lines of adaptation to those different environments. Then the different populations of mammals arose with the very similar skeletons being used in very different ways. Consider yourself, your dog, and whales to see the similarities in skeletal structure with vast differences in use.
No, not all multicellular organisms have skeletal systems. While many animals, such as vertebrates, possess internal or external skeletons for support and protection, other multicellular organisms, like jellyfish or sponges, lack a skeletal structure. Instead, they rely on other means, such as hydrostatic pressure or a soft body structure, for support and movement. In summary, skeletal systems are not a universal feature among multicellular organisms.
Bioimmuration is a process where dead organisms are preserved by being encased in a hard substance, such as calcium carbonate or silica, by other living organisms. This leads to the formation of fossil-like structures that retain the shape and details of the original organism. It is a common phenomenon in marine environments where organisms utilize shells or skeletons of dead organisms to create a protective structure.

To my knowledge, there are no mammals that do not have skeletons. One of the classifications of a mammal is that is has a vertebrae, which would need the rest of the skeletal structure to support it.

We have skeletons so that we don't look like a big glob.
The Yellow Calcareous sponge is Arthuria canariensis (formerly Clathrina canariensis, and also previously classified in the genera Nardoa, Leucosolenia, and Ascuris).Clathrina clathrus (the typical Clathrina species) is also yellow, bit has a dissimilar structure.
Sedimentary depositional environment: Area of deposition Alluvial fan: Continental deposits of gravel and sand Sand dunes: Sand mounds in the desert Beach sand: Shoreline deposit of sediments Reef: Calcareous skeleton from organisms build this wave-resistant structure -.-
yes don't you see in Tom & jerrywhen cats eat fishes and through the skeleton ?? Alternate answer: Yes fish have skeletons. Some fish skeletons are composed of cartilage and some fish skeletons are composed of bone much like human skeletons. FISH ARE VERTBRATES WITCH MEANS THEY HAVE BACKBONES
The skeletons of lampreys and hagfishes are made of cartilage rather than bone. This cartilaginous skeleton provides structure and support to their bodies without the need for true bones.
