Soft corals are colonial animals and some do have calcium carbonate skeletons of a sort.

Zooxanthellae provide carbohydrates to the coral through photosynthesis, allowing their host (the coral) to direct resources toward growth and constructing its calcium carbonate skeleton.

Assisted by other animals with calcium carbonate skeletons and also coralline algae, corals form complex, three - dimensional reefs.

Given the ever warmer and more acidic water, corals have to channel more energy into calcification, the energy - demanding process governing the formation of their calcium carbonate skeletons.

In groundbreaking research, a team of scientists from Australia's ARC Centre of Excellence for Coral Reef Studies, at the University of Western Australia and France's Laboratoire des Sciences du Climat et de l'Environnement, has shown that some marine organisms that form calcium carbonate skeletons have an in - built mechanism to cope with ocean acidification — which others appear to lack.

According to Wiki, in marine invertebrates «The extinction primarily affected organisms with calcium carbonate skeletons, especially those reliant on stable CO2 levels to produce their skeletons.

These algae (dinoflagellates) are very small and provide a biological environment within which the coral can build its calcium carbonate skeleton.

this reduces the acidity (lowers the pH) and creates an internal environment inside the coral, allowing the polyp to lay down its calcium carbonate skeleton 7.

«All organisms that produce calcium carbonate skeletons (including shells, crabs, sea urchins, corals, coralline algae, calcareous phytoplankton, and many others) depend on their ability to deposit calcium carbonate, and this process is largely controlled by the prevailing water chemistry.

These calcium carbonate skeletons are essential not only for their survival, but also for providing the habitats for diverse ecosystems, including deep - sea fish, eels, crabs, and sea urchins.

According to Wiki, in marine invertebrates «The extinction primarily affected organisms with calcium carbonate skeletons, especially those reliant on stable CO2 levels to produce their skeletons.

Corals record changes in local rainfall and temperature as subtle variations in the ratio of two isotopes of oxygen incorporated in their calcium carbonate skeletons.

In addition to the corals, many of the tiny animals that make up plankton have calcium carbonate skeletons; they provide one of the greatest food sources for cephalopods (squid and octopus), fish, dolphins and whales.

Scientists have long known that corals are the unwitting record - keepers of the deep, chronicling minute changes in ocean temperature, salinity, chemistry and even sea levels as they slowly grow and add to their calcium - carbonate skeletons.

Coral reefs are threatened by rising water temperatures, ocean acidification, and sea - level rise.3, 5 Coral reefs typically live within a specific range of temperature, light, and concentration of carbonate in seawater.6 When increases in ocean temperature or ultraviolet light stress the corals, they lose their colorful algae, leaving only transparent coral tissue covering their white calcium - carbonate skeletons.6 This phenomenon is called coral bleaching.

Experimental work on dissolution of the carbonate skeleton has been carried out on nonliving New Zealand bryozoans [82].

Finally, global warming and ocean acidification are expected to affect calcification in all marine organisms that have calcium carbonate skeletons, including larval and adult and free - living and sessile animals, shelled protozoans, and calcareous algae.
