Acropora Millepora belongs to the Acropora genus. It is found mostly in reefs located in the Indo-Pacific and there are many species that abound. The habitat for the acropora millepora must be sufficiently lit. In fact, it is believed that settlement orientation may even be effected to some degree by light intensity, so this is something important to consider in regards to acropora millepora.
Acropora Millepora Appearance
The acropora millepora is a broadcasting, hard coral species that may reach more than 5 millimeters in diameter over a short period of time. Generally, the acropora millepora grows vertically and the polyps are usually a millimeter or so in diameter.
Acropora Millepora Reproduction
Sexual reproduction known as mass spawning is possible in the acropora millepora, which is a reef building coral. This only happens one time per year over the period of a few nights when the moon is at its fullest. The coral colonies release large amounts of both sperm and eggs. Once these have formed gametes they will not become actual coral until they have gone through the fertilization and the development of the embryo. The next stage is larval growth while ht final stage is settlement and ultimately metamorphosis.
Acropora Millepora Survival
The likelihood of survival in any of these stages is low because of factors that are both biological and physical. These include waves and currents, wind, water salinity, and even the abundance of predators. Suspended sediments may also cause a problem with fertilization. Once the embryo has been fertilized, however, the suspended sediment does not appear to be a problem.
Acropora Millepora Larvae Mortality
The mortality for new coral larvae is incredibly high and it is believed that mortality in juvenile acropora millepora could be close to 90%. When there is controlled larval density then the survival rate appeared to be more stable however when it was not controlled.
Acropora Millepora Details
In general, before sexual reproduction can take place the individual coral must reach a certain size. Generally, the reproductive output of the body begins to function as the body is large enough to accommodate the new function. An interesting aspect about this coral is that the various species and grows very close to one another in the wild. Since they simultaneously spawn, the coral can fertilized other species, those that are related and otherwise. Because of this it is not uncommon to find hybrid acropora millespora. It appears that the hybrid embryos had no difficulty later on.
