Is salinity a condition required for formation of coral reefs?
Also, isn't 27-33% salinity just excessive!?
Salinity is an important condition for growth of coral reefs, because it helps in calcification and forming the calcium and carbonate shells.
It isn't excessive; had that been the case we would have had corals near fresh water areas also.
Thanks for the explanation! :)
The reason I had eliminated that option is because normal salinity is approx. 35 parts per thousand (i.e. 3.5%) and hence 27-33% salinity felt extreme
