Other species of coral reproduce by ejecting large quantities of eggs and sperm into the surrounding water. Reef-building corals, also known as “stony” or “hard” corals, reproduce in several ways - one of the most common of which is broadcast spawning. That means new organisms are created from a single organism – they clone themselves! Hard (or stony) corals reproduce by releasing their eggs and sperm all at the same time. About three-quarters of all stony corals produce male and/or female gametes. Remember that corals are sessile so they have to be creative when it comes to reproduction. Scolymias do just this—each coral releases eggs and sperm into the water. In asexual reproduction, new clonal polyps bud off from parent polyps to expand or begin new colonies. Reef-building corals, also known as "stony" or "hard" corals, reproduce in several ways - one of the most common of which is broadcast spawning. Although this could, theoretically, happen in the home aquarium, these corals have never successfully reproduced in captivity. This bizarre and beautiful phenomenon starts when male and female corals release reproductive cells, called gametes, into the water.

The process of producing offspring having similarities (biologically or genetically) with the parent organism is known as reproduction. Believe it or not, corals do produce both sexually and asexually. How do Staghorn Corals reproduce?

Other corals, such as elkhorn and boulder corals, are gonochoric, meaning that they produce single-sex colonies. Reproduction is the process of creating offspring. Corals prefer clear and shallow water, where lots of sunlight filters through to their symbiotic algae. Other species of coral reproduce by ejecting large quantities of eggs and sperm into the surrounding water. When crabs reproduce they assume the doubler position. The sperm and egg merge and form a planula larva, which matures inside the body of its mother. Asexual reproduction occurs by fragmentation or budding/fission; both of which do … It is possible to find corals at depths of up to 300 feet (91 meters), but reef-building corals grow poorly below 60–90 feet (18–27 meters).
