Pies Posted October 5, 2005 Report Share Posted October 5, 2005 Growth happens at night when the polyp is able to extend to its maximum, it is then, at night when the polyp is extended that it can secerete bicarbonate and build its skeleton. They don't grow during they day, the don't grow if their polyps can't extend at night. Pie Quote Link to comment Share on other sites More sharing options...
chimera Posted October 5, 2005 Report Share Posted October 5, 2005 They don't grow during they day thats a big call not sure if i agree. In addition to affecting the shape of a colony’s growth, environmental factors influence the rates at which various species of corals grow. One of the most significant factors is sunlight. On sunny days, the calcification rates of corals can be twice as fast as on cloudy days (Barnes, R.S.K. and Hughes, 1999). This is likely a function of the symbiotic zooxanthellae algae, which play a unique role in enhancing the corals’ ability to synthesize calcium carbonate. Experiments have shown that rates of calcification slow significantly when zooxanthellae are removed from corals, or when corals are kept in shade or darkness (Lalli and Parsons 1995).
