🪸Proud and grateful to be part of these coral research projects!🪸😄 You can watch the full episode here 👉🏼 youtube.com/watch?v=tw1PTe… @NatGeo @RSRC_KAUST #redsea #coralreef

It depends on the species. In this case, they were all settled in the next day

🪸3 days after spawning, these tiny Galaxea larvae are on a mission: to find the perfect place to settle and begin their life as coral polyps. Off they go!✨ #coralreproduction #coralspawning #marinescience #coralreef #coral #marinebiology #CoralSymbiomiXLab

Busy weeks at work!🪸🔬👨‍🔬 . . #coralreef #coralspawning #marinescience #coralreproduction #coral #coralsymbiomixlab

@fakhrurr_ozi It’s a time-lapse :)

@Alex_prie Wow This larva move at normal speed?

Coral larvae ready to go!🪸 #coralreproduction #coralspawning #marinescience #coralreef #coral #marinebiology #CoralSymbiomiXLab

🪸Look at these tiny Platygyra recruits, just 20 days after spawning! You can see the detailed morphology of their tentacles taking shape.👽 #coralreproduction #coralspawning #marinescience #coralreef #coral #marinebiology #CoralSymbiomiXLab

I don’t know what it is about this picture, but I’m completely hypnotized by this little Galaxea polyp 🪸✨ #coralreproduction #coralspawning #marinescience #coralreef #coral #marinebiology #CoralSymbiomiXLab

🪸And just like that, the third season of coral spawning 2025 is officially underway! 🎉 Of course, it had to happen on a weekend. 😂 #coralreproduction #coralspawning #marinescience #coralreef #coral #marinebiology #CoralSymbiomiXLab

🪸Time-lapse of our 4-months-old Galaxea babies. With the right light and an optical filter, it’s possible to see the green fluorescent protein (GFP) and the progressive accumulation of symbionts (the red dots) #coralreef #marinescience #coral #coralspawning #CoralSymBiomiXLab

@GerardRicardo01 Wow, that's really interesting! I’ve not seen the polar bodies, but I think I might have observed in some eggs that the first cleavage furrow does appear to originate where a sperm clot was. I'll keep a closer eye on this during future spawns. Thanks for bringing it up!

@fakhrurr_ozi Yes, some of our systems are programmed to induce spawning during midday instead of at night :)

@Alex_prie 11,40 am? Spawning in the day?

Cause corals don’t know about our days off (or do they…?)🤔😂 Galaxeas’ turn. Interesting split spawning observations in some colonies.🪸 #coralspawning #coralreproduction #coralreef #marinebiology #CoralSymBiomiXLab

Busy these last nights indeed!🔥Alongside more Acropora spawning events, the Platygyras decided to join the party!🪸 #coralspawning #coralreef #coralreproduction #marinebiology #CoralSymBiomiXLab

Night three of Acropora spawning watch! 🤩 So many unforgettable moments – definitely worth the lack of sleep! #CoralSymBiomiXLab #coralspawning #coralreef #coralreproduction

The second night promises to be busy!🪸😄 #coralspawning #coralreef #CoralSymBiomiXLab

The night is just beginning!!🪸 #coralspawning #coralreef #CoralSymBiomiXLab

@fakhrurr_ozi We expect it will be in April

@Alex_prie Wow five years! It will be spawning today?

🌕🪸Our Acropora hemprichii colonies are showing signs of egg development! Let the countdown begin!⏰ #coralspawning #CoralSymBiomiXLab

@fakhrurr_ozi They are colonies that we have had in our display tanks for about five years now :)

@Alex_prie Wow fantastic! Is it in the wild?
