A Coral Is Born | Deep Look

[@rosaamandatuirangrobet8612]

Hi everybody! My name is Rosa Tuirán and I'm the producer of this Deep Look episode. If you have any questions, I will do my best to answer them! Thanks for watching :)

[@TedClark805]

Why do you promote the climate change lie? Money obviously, but I would hope at some point morals would kick in. Silly of me.

[@cjc.1498]

How long does it take to push out one Deep Look? the quality and content is discovery channel worthy

[@12am12am]

Do the free-swimming planula make swimming in the seas itchy after a fulllmoon? These are stinging cnidarians.

[@rosaamandatuirangrobet8612]

Hi@@cjc.1498 It normally takes a couple of months or a bit longer to produce an episode from start to finish!

[@vidyanshukrishna6755]

Great work and the content speaks for itself 👏. By the way, i like the voice and felt the sincerity with which you made the video.🙂

[@-_-j]

I love that you guys give a space for the producer of the episode to answer some questions. This is such a good way for the public to realize someone had to research and coordinate every aspect of the making. And what a video! I worked for a company that didn't even give credit to anybody!

[@KQEDDeepLook]

Our pleasure!

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

[@smurfyday]

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]

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]

​@@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.

[@stevens9625]

9 years ago during a dive at Cairns Australia, I was dismayed at just how bleached the coral patch looked despite being in an area picked by the tour operator. I can't imagine what less favourable areas would look like and things in terms of ocean temperature have just gotten worse since. 😢

[@aprilmeowmeow]

:(

[@T4ckyy]

I’ll use deep look to educate my kids!

[@KQEDDeepLook]

Wonderful!

[@unoreversecard1o1o1o]

Don’t homeschool them tho!

[@JuffoWup78]

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.

[@2WhiteAndNerdy]

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. 😄

[@soda_fairy]

That is fascinating

[@vincentgarcia6409]

So fascinating that these tiny planula adventure around and eventually settle in what will, hopefully given enough time and a healthy environment, become a coral reef. I studied biology for five years and watching these videos illustrate these little marvels of life is such a treat to the inner nerd. Thanks for putting out consistently bumper content!

[@KQEDDeepLook]

You are welcome, Vincent!

[@Koekie5616]

Thank you for this great channel!

[@KQEDDeepLook]

Our pleasure! We appreciate your support!

[@KalEmberTTV]

you guys are absolutely my favorite nature youtube channel, your content is so professional!

[@KQEDDeepLook]

Glad you enjoy it!

[@yashnigam2704]

You can feel the scientists here truly love and care what they do. Thank you for giving us a view of the world which many of us won't be able to see live throughout our lifetimes. Love from India.

[@m1thun27]

This is the perfect answer to "Where do babies come from?" 🌝

[@piercedswag]

been watching this channel since i was 14 im 16 now and i love this so much wish they showed yalls videos in school

[@niskalawastu5103]

So delicate and soothing ❤🪸

[@mapletree6308]

That "Look familiar?" Had me dying😂😂 🤣

[@kimbratton9620]

Deep Look always has something to look forward to!!

[@instantamazon]

Shout out to Seth for the consistently engaging and enjoyable music on these Deep Look episodes 🙌🙌

[@juansalvemini9270]

If there were emmies for KZbin, you’d get an Oscar. Excellent content

[@KQEDDeepLook]

Wow thank you!

[@Mary-sh2bp]

It’s so freaking insane how we all start exactly the same with the egg and the sperm and we just diverge into different species after. 😅

[@martinpellicer8489]

There is a very good movie/documentary that explains this in more details “chasing coral”

[@alestine]

I hate the fact that KZbin doesn't have a reaction button. I would like to give this video this "care" reaction! I hope that one day giant oyster clams will be featured in Deep Look.

[@KQEDDeepLook]

Oooh - giant clam!

[@happyhippoeaters4261]

"Please stop swimming in the "Snow Globe" sir."

[@RedSelf]

They look a little bit like a baby jellyfish, so cute! And sad that they are in danger :/

[@zacharywong483]

Fantastic visuals and video, as always!

[@samuelepesce]

Thank you, each video is literally astonishing and this one is too

[@markg1490]

Love these informative videos. Thank you for sharing

[@KQEDDeepLook]

You are so welcome!

[@LiquidMotionFilm]

Rosa, awesome!!!! 😀😀😀Bravo!!

[@teabsv.21]

Will we get a deep look at the giant burrowing cockroach from Australia?

[@chuongnguyen2650]

Deep look has taught me more stuff than school has taught me lol

[@nelsonianb1289]

Yay more deeplook!

[@Unknown-xm8ll]

Deep look has the best informative videos thanks a lot 🙏

[@KQEDDeepLook]

Glad you think so!

[@jpbinitialsko]

Finally, a new video❤️

[@cjc.1498]

A planula with a plan 🔥🔥🔥🔥🙏🙏🙏

[@KQEDDeepLook]

well played!

[@Merajkun0606]

Always love deeplook's every video ❤❤ Looking forward to the next.

[@Alienboi2005vidsandstuff]

I love watching deep look

[@KQEDDeepLook]

We love making these videos for you!

[@ArcTifocx]

Sounds like we need more than Ms. Frizzle to restore the environment hastily

[@Atlas__00]

Ottimo lavoro! 👍

[@KiasaruToshiki]

It's interesting that they're soft and are animals but when they die they become like bone.

[@patchizek4716]

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!

[@graphite2786]

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!

[@NewMessage]

I know I'm late, but what can I say... was too cloudy here to see the moon.

[@Gsrxq]

Awesome video!

[@t.z2359]

The grouch, and spawning of Cnidaria, rarrly fail to amaze me.

[@MakinaSatanica]

Can you make a video about the sandfly, please?

[@kyleoliver637]

That’s wild how this footage is captured.

[@TheColdArrow]

well done

[@OceanMelodyMedia]

To everyone who's reading this, I pray that whatever is hurting you or whatever you are constantly stressing about gets better. May the dark thoughts, the overthinking, and the doubt exit your mind. May clarity replace confusion. May peace and calmness fill your life. 🙏

[@AndyTheDude2]

deep look you are just my caretaker when I'm bored

[@KQEDDeepLook]

Happy to do that!

[@Unbreakable71]

Well done 👍

[@kcikdubb]

i love these videos

[@KQEDDeepLook]

Thanks!

[@BrimstoneMoth]

Thanks for the video, I cried

[@AwfulnewsFM]

I love creatures

[@plantdemon2137]

DEEP LOOK IS AWESOME

[@KQEDDeepLook]

WOO HOO!

[@FahqYou-uu3qw]

Its crazy how we have to build an ecosytem and not restore one

[@callystarizka-tata7892]

Hey guys, my name is Callysta and I'm the fan of Deep Look. This episode was premiered last year and Deep Look made this episode 6 February 2024. Everyone was right. Btw this video has a sponsor. I hope you guys enjoyed it Thank you for watch and special thanks to Deep Look for creating this episode

[@anonymousperson8259]

A planula! Sounds so cute 🥰. I feel like being cheesy and saying I have a "planula" next time I am working on an idea or dream in it's "embryonic" stages. Lol

[@baronghede2365]

It all looks so fascinating, Blessed Be.

[@Lord_Lionidas]

“Umm I was just watching the sports channel, Gary!”

[@GuagoFruit]

So much beauty in the world, I'm scared thinking that one day not too far into the future I'll only get to see it as historical films rather than with my own eyes.

[@Sci5309]

I just love how Deep look creates such glorious videos💯💙💚 , it gives me so much insight of what I have known so far so little of what actually is happening around. Following Deep look for over 2 years now made me clear about what carrier I want to have that is a climatologist, thankyou so much Deep Look!❤

[@justprettyshort]

LAURA IS THE BEST NARRATOR!!! NO ONE CAN UNCONVINCE ME

[@Tsarbloonba]

I kinda dont understand how corals are like: guys its a tad bit warmer lets expel our life force that can probably survive this

[@willianphilipemeirelles9318]

Amazing !

[@anatunkia]

I helped the Toronga Zoo cryobank with collecting the gametes at a spawning event with AIMS. One vile contained over 9 million sperm that was successfully stored for the next 70yrs

[@reanrae4758]

More. More….. ❤❤❤

[@fortnitelegendary2723]

Mom its getting freaky in here again

[@TragoudistrosMPH]

0:33 notice them twitch together. Interesting!

[@junchan_3200]

When I was a baby my family had a documentary about marine life and coral reproduction was my favorite 😢

[@franklinblunt69]

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.

[@1412497129489rr]

Jellyfish and coral are essentially the same things just slightly different and ide guess neotony plays a big roll

[@jongkim6431]

Everyone shut up!! Deep look is up!!

[@courtneyjefferson8396]

Can you please make a video about the basket star, which is a real animal, it's basically a fancy brittle star

[@Silent-N]

I've always found it bizarre that coral is considered an "animal" just like a mammal, bird, reptile, etc.. I fully expect that one day some scientists in a position of influence will finally find enough sense to classify it under its own separate kingdom instead, much like how fungi eventually was after centuries of being classified as a plant.

[@TukuDey-p9r]

Ty😊

[@planetballuniverse]

What if it can’t settle down and all the areas can puncture it? 2:19

[@FayadRNiloy]

Make a video about hydra & thanks for making such beautiful videos...

[@GaryAa56]

Just like we need rainforests on land, the Ocean needs the great barrier reef.

[@Hambonillo]

Catfishing coral for science.

[@zooemperor3954]

So the light of a waning moon is a factor? I generally thought it was a full moon. You learn something new every day. And hopefully we can protect coral reefs from dying off. Thanks Deep Look! Can’t wait to see more.

[@rosaamandatuirangrobet8612]

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.

[@abhirajbhokare1989]

Brilliant.

[@bluefish4999]

I love to night dive, forget the big pelagic fish and sharks, the coral itself are the rock stars of the ocean.

[@neomicryo]

its amazing how close the corals are to jellyfishes !

[@KQEDDeepLook]

So true! Power to the planulae!

[@osmosisjones4912]

Didn't see this in finding Nemo

[@jikoh09]

Cool vid!

[@KQEDDeepLook]

Thanks!

[@asyrafsafwan3095]

Dear deep look, please do diving bell spider

[@coldsobanoodle7407]

"Only one of these guys will get in" *war flashbacks*

[@melodyparra2960]

It looks like a reverse snow globe

[@AnirudhTammireddy]

is the footage from the sea or the awesome lab the researchers set up from the video?

[@rosaamandatuirangrobet8612]

Hi! Most of the footage is from the California Academy of Sciences Coral Lab!

[@AnirudhTammireddy]

@@rosaamandatuirangrobet8612 tysm.

[@ikramhakim6591]

How does it stuck itself to the seafloor?

[@rosaamandatuirangrobet8612]

Hi! The planula secretes calcium carbonate, the chalky substance that forms its skeleton.

[@frankeneh-lf6fb]

I just noticed that your 10th anniversary is in this year October. So I'm saying happy 10th birthday!

[@WedgyBlue]

Wow they are animals and when they are young, its a wormy 😮

[@KQEDDeepLook]

Yep!

[@miklee2535]

wait a minute does that mean when there's a blizzard in SpongeBob its technically referring to this

[@thairinkhudr4259]

Nature's undersea fractals.

[@xmattar]

I wana know the background music

[@KQEDDeepLook]

It's original - our amazing composer is Seth G. Samuel. :-)

[@orawal]

So they're also "holobionts" ? :) lessons from Deep Look

[@fixme.96]

So basically they're just fungus of the ocean???😂

[@rebex78]

Why the video has such low definition? 😅

[@shardinalwind7696]

And that is how the coral, do

[@MericHazar-f1m]

I’m new what did I miss

[@grac1ep1e]

they remind me of the white thingies in the boy and the heron

[@osmosisjones4912]

Most of the ocean is to cool for coral warming oceans would remove more carbon
