"Life cycle of corals." Cairns Favorite Tip by Sharrie

Cairns General: 47 reviews and 81 photos


Favorite thing: <BR>At least learn a little of how corals reproduce. Right? After all, it is collectively the largest living organism in the world, so, please show some due respect for their survival :-)
<BR>Coral polyps reproduce sexually by producing sperm & eggs which unite to form tiny rounded larvae called planulae. Each polyp is both male & female. It releases a bundle of eggs & sperm into the sea water on only 1 or 2 nights each year in late spring or early summer. The planulae will then float in the surface waters for a short time & swims down to find a suitable spot on the hard reef surface where it will change into a polyp & begin the process of forming a colony.
<BR>Coral colonies can also reproduce asexually, ie, parts of the colony break off & survive to form a separate colony.
