When the moon, sun and ocean temperatures all align, an underwater "snowstorm" occurs. Corals put on a massive spawning spectacle by sending tiny white spheres floating up the water column all at once.

-
About 10 days after a full moon, an upside-down underwater blizzard occurs. Tiny spheres float up the water column. But they're not sand particles or algae, they're packets of egg and sperm from coral. This snowlike spectacle is known as coral spawning.
Corals are not plants or rocks, but colonies of hundreds of thousands of tiny animals called polyps. These polyps look like underwater flowers, with a soft body, a mouth and tentacles.
Polyps obtain nutrients from single-celled algae called zooxanthellae, which live in their tissue. The coral provides protection and compounds for photosynthesis. In return, zooxanthellae supply elements to build calcium carbonate skeletons that give them their stony structure.
Corals can’t move to find a partner and mix up their gene pool, so they’ve adapted a unique reproductive strategy that allows their eggs and sperm to fertilize with other colonies. The polyps release their gamete bundles together, at a time determined by environmental factors determined by the lunar cycle, setting sun, and temperature. Scientists believe this ensures high levels of fertilization across the ocean.
--- What are corals known for?
Coral reefs provide habitat for a quarter of marine life, including fish, crustaceans, mollusks and sea turtles. Corals can be found throughout the world’s oceans, in both shallow and deep water.
- How long can a coral live?
Studies have shown that some corals can live up to 5,000 years, making them the longest- living animals on Earth.
--- Do all corals live in warm water?
No. In fact, over half of all known coral species are found in cold, deep and dark waters. These corals feed by waiting for small food particles to swim by, and they lack the symbiotic algae that live in the tissue of warm water corals.
- Do corals have other forms of reproduction?
There are many species of coral, but only two main types of reproduction. Corals reproduce either asexually, by budding, fragmentation and fission, or sexually, through broadcast spawning and brooding.

I have also heard that scientists are trying to breed heat tolerant corals that can withstand the heating oceans.

@smurfyday 3 ай бұрын

These can make incremental gains, but if we don't drastically slow down warming, it won't be enough. Evolution probably would've given us the solution if that's feasible

@jesipohl6717 3 ай бұрын

my guess is the interspecific relationship is more complicated than people realise and that this process will take too long to save what we have. It's not just the coral that has a problem it is also the algae.

@Chirostenotes Ай бұрын

@@smurfyday Unfortunately evolution can't act in advance and traits like that usually don't evolve on such a short timescale in nature, but that doesn't preclude such a trait from existing. Reef building corals have been around since the Late Triassic and have endured plenty of catastrophic climate change and extinction events, but wouldn't necessarily keep a resistance to higher temperatures even if it was present in their ancestors at times when the Earth was generally warmer, since they've now adapted to cooler temperatures.

I remember a few years ago, I went to an aquarium hobby convention. One of the talks was a scientist basically making a plea on discovering the trigger for coral spawning so as to be replicated. Generally speaking, all corals in the aquarium hobby are clones. They break off a piece to sell and then repeat. And those pieces grow back to the full size with the new owner able to just do the same thing. I never heard anyone was able to replicate breeding reliably in the lab yet though. Nor had I heard of someone doing it at home.

Helps a ton to get involved with a local aquarist club. When I was into reef keeping, all of us in the club (hundreds at least) had prolific corals that would multiply like crazy. Had a few guys who made and shared tons of aragrocrete plugs for us to make frags and share with each other. I pretty much spent like no money on corals! Haha. We all had more than we knew what to do with. 😄

It's fascinating how they have adapted to light levels, and variations of them due to even variations as small as the phases of the moon. I wonder how that interplays with the tides and the effects on ocean currents that might make it easier or harder for the eggs and sperm from different coral colonies to encounter and produce offspring. A wonderful video as always, and shout out to the researchers who discovered this phenomenon!

Sometimes the very act of spawning can kill the whole reef! Several years ago , at a place called Coral Bay ( not on the east coast like the Great barrier Reef but on the west coast, Ningaloo reef) abnormal weather conditions forced a lot of coral spawn back into the reefs where it came from. The spawn and gametes died and caused a major pollution event and killed nearly 100 hectares of coral. Thousands of fish died and caused even more toxic conditions. It was horrible!

Thanks for this although have concerns about vagueness with actual issues affecting coral & else. Coral more resilient with temperature than espoused, but not pollutants among other issues & threats that are anthro-origin. Prolly depends upon various environmental factors & speciation, but polyp lifespan usually about two or three years although unsure how use chronological time for this when seasonal & else matter? Coral process had always fascinated me, required conditions & how allude more about place. Even with requirements & probability for spawn & fertilize then zygote must survive for develop over 73 hours into Planula larva that must find place for settle on colony, while particular Zooxanthellae have to be available from else alive amid vast water resource yet exclusively attracted for amazing examples of symbiosis in action & establish an oblgate mutualistic relationship. Many factors for coral to happen, so need specificity that aid awareness & action that address the specific inhibiting issue so colonies may perpetuate & provide the functions they serve.

I've always found it bizarre that coral is considered an "animal" just like a mammal, bird, reptile, etc..

Hi! Corals are synched to the lunar cycle. The full moon is a trigger, but they don't spawn during a full moon. They spawn during a waning moon.
