breeding method
Coral can reproduce sexually or asexually. Sexual reproduction of coral has the advantages of strong reproduction, high genetic diversity and no damage to the mother coral. Coral eggs and sperm are produced by gonads on the diaphragm and discharged into the sea through the mouth.
Fertilization usually occurs in seawater and sometimes in the gastric circulation cavity. Usually fertilization only occurs between eggs and sperm of different individuals. The fertilized egg develops into a floating larva, which is covered with cilia and can swim. After a few days to weeks, it will be fixed on the solid surface and develop into a hydra.
It can also be propagated by budding, which will not be separated from the original hydra after budding. New buds keep forming and growing, so they breed into groups. When the new hydra grows and develops, the old hydra under it dies, but the skeleton remains in the population.
