If the stressful conditions persist, the polyp eventually dies.[23] Zooxanthellae are located within the coral cytoplasm and due to the algae's photosynthetic activity the internal pH of the coral can be raised; this behavior indicates that the zooxanthellae are responsible to some extent for the metabolism of their host corals [24] Reproduction[edit]
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.
Increasing sea temperatures in tropical regions (~1 degree C) the last century have caused major coral bleaching, death, and therefore shrinking coral populations aqui since although they are able to adapt and acclimate, it is uncertain if this evolutionary process will happen quickly enough to prevent major reduction of their numbers.[77]
Polyps feed on a variety of small organisms, from microscopic zooplankton to small fish. The polyp's tentacles immobilize grupo coral or kill prey using stinging cells called nematocysts. These cells carry venom which they rapidly release in response to contact with another organism. A dormant nematocyst discharges in response to nearby prey touching the trigger (cnidocil).

Soft corals vary considerably in form, and most are colonial. A few soft corals are stolonate, but the polyps of most are connected by sheets of coenosarc [def], and in some species these sheets are thick and the polyps deeply embedded in them.
Some soft corals encrust other sea objects or form lobes. Others are tree-like aqui or whip-like and chem a central axial skeleton embedded saiba mais at its base in the matrix of the supporting branch.[nove] These branches are composed either of a fibrous protein called gorgonin or of a calcified material.
Corals' many colors give it appeal for necklaces and other jewelry. Intensely red coral is prized as a gemstone. Sometimes called fire coral, it is not the same as fire coral.
