Coral skeletons are biocomposites (mineral + organics) Ca carbonate, in the form of calcite or aragonite. In scleractinian corals, "centers of calcification" and fibers are clearly distinct structures differing with respect to both morphology and chemical compositions of the crystalline units.
[28] High failure rates afflict many stages of this process, and even though millions of gametes are released by each colony, few new colonies form. The time from spawning to settling is usually two to three days, but can be up to two months.[29] The larva grows into a polyp and eventually becomes a coral head by asexual budding and growth.
In the Caribbean and tropical Pacific, direct contact between ~quarenta–70% of common seaweeds and coral causes bleaching and death to the coral via transfer of lipid-soluble metabolites.[54] Seaweed and algae proliferate given adequate nutrients and limited grazing by herbivores such as parrotfish.

Aristotle's pupil Theophrastus described the red coral, korallion, in his book on stones, implying it was a mineral, but he described it as a deep-sea plant in his Enquiries on Plants, where he also mentions large stony plants that reveal bright flowers when under water in the Gulf of Heroes.[2] Pliny the Elder stated mais info boldly that several sea creatures including sea nettles and sponges "are neither animals nor plants, but are possessed of a third nature (tertius natura)".

Many corals, as well as other cnidarian groups such as sea anemones form a symbiotic relationship with a class of dinoflagellate algae, zooxanthellae of saiba mais the genus veja mais Symbiodinium, which can form as much as 30% of the tissue of a polyp.[16]:23-24 Typically, each polyp harbors one species of alga, and coral species show a preference for Symbiodinium.[17] Young corals are not born with zooxanthellae, but acquire the algae from the surrounding environment, including the water column and local sediment.
Some soft corals encrust other sea objects or form lobes. Others are tree-like or whip-like and chem a central axial skeleton embedded at its base in the matrix of the supporting branch.[9] These branches are composed either of a fibrous protein called gorgonin or of a calcified material.

The comparison of coral strontium/calcium minimums with sea surface temperature maximums, data recorded from NINO 3.4 SSTA, time can be correlated to coral strontium/calcium and δ18O variations. To confirm accuracy of the annual relationship between Sr/Ca and δ18O variations, a perceptible association to annual coral growth rings confirms the age conversion.
