Coral trap prey in sticky mucus on their tentacles and move it to their mouth. The coral comes into contact with prey by the flow of water forcing it to come into contact with the tentacles and gravity cause heavy particles to fall into the tentacles. Once the food is moved to the mouth, it goes down the pharynx and to the gastrovascular cavity for digestion. Reproduction Corals reproduce sexual and asexual. They expand in size by budding.
Asexual reproduction is done by fragmentation.
There are broken pieces of corals that land on a suitable object and begin to grow a new colony. Sexual reproduction is completed by the corals releasing egg and sperm in the same 24 hour period. The sperm and egg float to the surface where they separate and fertilization occurs to form a zygote. Once a larvae forms, it attaches itself to an appropriate object to begin a new colony. Some coral has the sperm fertilize the egg before releasing them.
