Caryophyllia ambrosia, Alcock , C. These three ahermatypic solitary corals inhabit different depth ranges: C. All three species are hermaphroditic. Hermaphroditism in these species was found to be cyclical, with only one sex of gametes viable in any individual at any point in time, although gametes of both sexes were found together within a single mesentery.

Marine Life Cycles MarineBio T Marine Life Cycles Although at the surface the ocean can appear calm and quiet, in fact there is an enormous amount of life activity taking place, particularly at certain times of the year. Life Cycles A life cycle is defined as the developmental stages that an organism undergoes from its primary stage to the primary stage in its offspring. Life cycles range in complexity from extremely simple—as with unicellular bacteria that begin with fission forming the parent and ends when the parent asexually splits into two daughter cells—to increasingly complex—as with multicellular animals that begin with sexual reproduction and morph through developmental stages where their bodies undergo extreme changes. The Marine Life Cycle Reproductive strategies abound in the ocean where we have fission, budding, eggs hatching externally, eggs hatching internally, live births, some marine animals are born in freshwater, some are born on land, etc. The marine environment creates unique challenges to the cycle of life, some that have been met with amazing adaptability.
Corals How Do Corals Reproduce? Many species of stony coral spawn in mass synchronized events, releasing millions of eggs and sperm into the water at the same time. Click the image for a larger view.
