HERE IT IS: THE REVEAL! This is the first time in 15 years of studying corals that I've captured larval settlement in a clear timelapse Yet EVERY CORAL REEF in the world started from coral larvae doing THIS EXACT THING The black box of larval dispersal, now in full color🤯🤩😍

My colleague @CoralSci Dr. Kristen Marhaver shared her coral babies with me, so we could check the asymmetric activity of early ciliated fields. More details about this type of tracking: cell.com/current-biology/pdf…. @genikhovich @UlrichTechnau

Would you like to enjoy a baby coral this afternoon? Here's O. faveolata (the Mountainous Star Coral!) photographed a few minutes ago. It's just hangin out being one month old and hosting some symbiotic algae in its lil noodle arms🧡🍜

You can even see the tiny nubs of tentacles 7 through 12 starting to form!

PS here are the kinds of shenanigans that Mountainous Star Coral gets into if you give it a few centuries to hang out and make a bunch of copies of itself

Check out these cute coral friends growing in Florida 💜
Coral recruits are taking up their algal symbionts and growing well 🪸🤩 #coralreproduction #earlylifestage #sexualpropogation #growout #massivecorals (Images courtesy of Valerie Super and Daisy Ponce)

Would you like to meet the Great Star Coral Montastraea cavernosa? This one is six weeks old!💛 It started out pale and translucent, but it's done a great job making friends with some brown dinoflagellate algae (Symbiodinium!) Also, double the tentacles from 2 weeks ago💪💪

Video caption: A microscope video of a single brown coral polyp with white speckles against a white background. The polyp extends its 12 tiny tentacles and wiggles around happily. The video goes out of focus because it's so tall! It's about 1 or 2 mm tall. Video speed 150x.

(Yes, it's Symbiodiniaceae now, but we have a character count and an attention span running the show here)

Aw thank you for these lovely words @johntolva! And for pitching the idea of the fundraiser and making it such a big success!
Update on the Marhaver Lab campaign: we raised close to $11,000 for vital coral reef science. Details at ascentstage.com. Thanks to all who contributed to @CoralSci!

I can't overstate how serious the storm surge threat is in southwest Florida. #Ian will drive deadly surge into Cape Coral and Fort Myers, placing much of the area under water. If you live near the ocean in a surge zone, this is your last chance to leave...

Coral friends, please vote! Which way is "up" on a coral polyp? Left photo (smiley mouth) or right photo (frowny mouth)? I mean, yes, they're "radially symmetric" animals, but they're NOT REALLY radially symmetric... those little mouth grooves (siphonoglyphs) have a curve!

If you're crushed that you missed this absolutely low stakes low reward contest, the other way to get baby coral stickers is to donate to the lab! Just enjoy this weirdly previewed link to an actual nonprofit donation page and we love you💜🌴 multiplier.org/project/marha…
