If it makes you feel any better, all that pollen you're inhaling in the spring and that coats your car and porch and everything else, is plants (mostly trees) ejaculating into the air. So you're already walking around in it; might as well swim in it, too.

[@connorjohnson4402]

@@kerim.peardon5551 Yea this is very much true but if it were more like the ocean in the air you'd kinda have to dial up the weird and craziness up to 11. We would not only have the usual gamete clouds everywhere but we would also have a whole bunch of tiny baby versions of all the animals and plants floating around in the sky duking it out in microscopic battles for survival. The tiny versions would also probably look much wierder and different than the full size but there still be a bunch of tiny squirrels, or insects, or birds, or snails all floaring around with the tiny plant versions as well. That and a good number of them would be glowing or be able to make light so it would put fireflies to shame!. It would at least make cleaning off that car and porch a bit more intensive or dramatic to say the least.

[@annebartells777]

I grow corals and agree with you, but some corals do not use photosynthesis to get their nutrients. Many types of fan corals are like that along with the sun coral. I stay away from them as they are very difficult to keep alive because of their nutrient requirements. You have to feed them about 4 times a day or more. Putting that many nutrients in your tank can cause your tank to crash. They are not worth the trouble for me. SPS corals are difficult to grow because they are very unforgiving if your parameters are not perfect. The only corals that do not require feeding on a regular basis are softies

Sooo... reseeding reefs would seem useless unless the original cause of the coral’s demise was eradicated (rid the area of Crown of Thorns starfish, etc.) In retrospect hat would seem easier than reversing global warming which I believe has begun to affect places like the Great Barrier Reef sadly.

@@davidvento5481 begun? it's almost entirely dead, I remember reading about it as a kid

[@dawnchesbro4189]

​ @davidvento5481 reseeding coral is a proven way to sustain species biodiversity. Yes, crown of thorns seastars are a big problem, but that's also being managed through human culling and protection of Triton's Horn snails - natural predator to COT seastars. If reseeding didn't happen, certain species of coral would out-compete other species of coral, leading to monoculture forests of coral. And monocultures don't support larger biodiversity. I did benthic diving research in tropical oceans. Coral biodiversity supports a larger diversity of fish, invertebrates, and mammals.

I've got thallasophobia and despite that I've actually been scuba diving. Something that surprised me is that the coral made me deeply uncomfortable. Like I'm expecting hundreds of mouths to open up, or touching them to be like touching an anenome or jellyfish. Good to learn that I was actually completely correct, they are covered in tiny mouths, and they are also stingy like jellyfish.

[@Rubicola174]

Fun fact: Corals have thousands of mouths and all of them want to lick your feet.

[@PhoenicopterusR]

Nothing like learning that your greatest fears about the ocean are true, just not in the way that's expected.

[@AnaTorres-os8wt]

How cool that you scuba dived...dove?... in spite of your thalassophobia. I had to look that up, lol. But really, how cool to face that fear. Wish I could...

[@ASpaceOstrich]

​@@AnaTorres-os8wt Fortunately its relatively mild thallasophobia. I think its also gotten worse as I've gotten older too. The fact that it was with instructors and other people around definitely helped a lot. I'd probably do it again if the opportunity came up. But I'd never do it alone. A big part of what triggers the fear for me is that in the ocean you have so many more directions something can be approaching you from, and having other people around helps alleviate that because they can watch your back. Clear waters also helps a ton, as at least I can be sure nothing is approaching from in front of me.

[@cerclerouge3679]

i feel that but i'd call that more like trypophobia, i have it too

[@StuffandThings_]

What really gets me is that modern corals that partner up with algae for photosynthesis only arose during the Triassic. So for the _entire_ Paleozoic, with its famous reefs, those corals couldn't obtain any energy directly from the sun. Entire reefs built out of corals that had to actually eat. Wild stuff.

[@pauldeddens5349]

Not too far off with anemone, just imagine those but with more tentacles and longer mouths. A whole reef of those would be very dangerous, its probably why so many prehistoric fish had thick armor and shells. (Well, obviously not the main reason or only reason, but im sure a contributing factor, especially given the small size of many early sea creatures)

[@Daft_Vader]

Deep sea corals today still get on without photosynthesis

[@petergray2712]

​@@pauldeddens5349Not Anemones, sadly. Structurally they form large fan-like structures resembling tree branches, and they filter feed on zooplankton brought to them by deep sea currents.

[@pauldeddens5349]

@@petergray2712 Sure, but like their cousins they can still produce a nasty, if not lethal sting. Whose to say they couldnt have been predatory in a fashion in earlier oceans?

I think the Paleozoic corals actually had a different algal symbiont based on fossil evidence. We just don't know which ones.

[@smugsneasel]

You know, even though I was taught that Coral was an Animal very early on (Thank you Jumpstart 3rd Grade), I never ever questioned, even till now, how they reproduce after learning that fact.

[@AndrewPonti]

This synchronicity is insane because I was JUST watching something this week about scuba divers in Australia at the reef and always knew coral were animals, but my 35 year old brain finally thought, "I wonder how they actually work" then didn't look it up. Now THE BEST way for me to learn, Ze Frank, comes out with it??? How does the universe work like this? Also learning they can welcome algae into symbiotic cells for their mutual benefit is AMAZING. It's like if we were able to put a leaf or something to our skin and we were able to absorb them onto our arm and just get nutrients from the sun.

I can never wrap my head around the fact that corals are animals and yet they look and act like plants

[@Mangaka718]

expanding on that thought, they're animals that look and act like plants, but usually the plants that behave a *bit* like an animal. if that makes sense.

[@lizxu322]

I dont see plants expelling their digestive noodles to digest things, it reminds me more of sea stars and jellyfish, the latter of which was stated to be related. Aside from the fact that most cant move from its original location, its almost nothing like a plant (has no choloroplasts of its own, depends on algae for photosynthesis)

[@GoldenGrenadier]

IMO they operate more like a fungus or a really lazy ambush predator.

[@skie6282]

Its like if you took a bunch of ants and stiched their butts together, thatd be a coral. Or i guess for animals, stich mice

[@malakimphoros2164]

Plants are even weirder if you really think about it. Trees are gigantic columns that suck water from the ground powered mainly by pressure gradient. They can also communicate with eachother though webs of symbiotic mushrooms. They can lure predators to protect themselves from parasites and herbivores. Plastids are a whole other level of symbiosis too.

[@kerim.peardon5551]

If it's a temp thing as well, have you tried dumping out buckets of ice on a regular schedule?

[@chezmoi42]

Just don't inspire anyone to tow chunks of the Great Pacific Garbage Patch over there.

[@sdb9884]

This was the best explanation of coral bleaching I have seen, and now I understand it better. Thank you!

[@Evagating]

Between the belly laughs, I'm stunned at how well put together this is. How much time goes into a True Facts video like this one?

[@chezmoi42]

Are you new to True Facts? Welcome! The narration of every one of Ze's videos is sillier than the last, yet they are all stretched across a solid framework of scientific research and knowledge. Only he could say how long the takes to produce a script, on top of the hours/days/years put in by the researchers.

[@ericsfishingadventures4433]

I've been keeping coral in reef tanks for over 20 years and those close up shots we're amazing! And ridiculously hilarious! 🤣

[@paulkinzer7661]

'Coming across the wig of a drowning clown'. Now that is just poetic.

[@TheR3gi]

Jerry trying to get away w/ a lot this episode. He wanted to be more included 😂

[@metalmamasue3680]

I for one am gIad Jerry snuck that cute IittIe fish in the beginning 😉

[@g-gon8869]

No matter my emotional state,zefranks videos always cheer me up!😊

[@purplehaze2358]

"But these noodles like to come out and play!" I'm sure many people in the audience can relate to coral's desire to make use of their noodles.

[@MrJdsenior]

Yeah, underrated.

[@NatYourAverageNerd]

In high school biology class, the one thing I remember about when we watched a video about coral is that the narrator said, “While coral may be kinky...” and it became the class meme forever after.

[@jondekerguelen]

A “Lung Biscuit” absolutely hilarious! So damned creative, I absolutely love how extremely clever you are 100% of the time! Thank-you!

[@Candesce]

7:43 that is the most Lovecraftian thing I've ever seen in a real organism.

[@ButacuPpucatuB]

So mucusy and educational 👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽 Thank you! I hope the best for our corals all around the world 🧡🤞🏽

[@qwertydavid8070]

mucussy 🤤

[@matthewlook3597]

It is the mucus that binds us ❤🌎🤧

[@ModeratelyAmused]

That fish is adorable. I don't blame Jerry one bit for wanting to use that footage.

[@faithtaylor2449]

I wish this voiceover taught all my classes in school. Would’ve been WAY more interesting and helpful 😂

[@AshLeeeeee]

I feel better about the world, knowing that there are entire organizations centered around saving these beautiful keystone species of the ocean

[@TheHolyBushGod]

I was just looking for something to watch during my lunch break, and right before clicking on something i got the notification, thank you Franky

[@TheNavigator4552]

You still have half of the break break left

[@balanc-joy9187]

0:48 "These bundles are the pornographic equivalent of a Tide Pod..." *That* is where I started laughing! Not even a full minute in...

[@jamielandis4606]

I come for the humor, stay for the animals. ❤

[@brianaschmidt910]

Funny, it's the opposite for me

[@JeuslovesmethisIknow1982]

ZeFrank never disappoints EVER! Protect this man at all costs! 😂😂

[@KimberlyGreen]

Poor fishies. They just wanted to be at the party too. Mean ol Ze telling them to get lost. Also, coral mouthholes are the stuff of nightmares! 😱

[@AB-un4io]

Yes!!! Just what we needed!! Thank you for another incredibly fun while still being educational video. Why can’t we get teachers like this in school? He’s simply one of the best!! Take care all! 🙂

[@DuchessofEarlGrey]

Imagine having a teacher who regularly has to interrupt themselves during a lecture to berate a "Jerry" (TA) who just sits quietly in a corner with a shit-eating grin.

[@cenciende9401]

Because they don't get paid enough!

[@darkwynggryph]

ZeFrank has such a knack for giving us educational AND hilarious videos of the weird living things that we share the planet with

[@StrangeTerror]

Zefrank doing a coral video!? 1 more off the bucket list! Thanks guys!

[@EHenryscuba]

As always hilariously educational

[@elizabetheaton3882]

Great narrations, even sillier sound effects! I learned some things and laughed too. Thank you Ze Frank! 🙏

[@carolyntalbot947]

Ze Frank is a gosh-darn international treasure, and that’s better than a plain _national_ treasure! 🐠🐙🐬🦀

[@amariea03]

Thank you for all your full length content. I don't know what the internet would do with out you

[@cmataira]

As usual the best mix of awesome, creepy and disgusting! I love Ze Frank videos! So full of curiosity.

[@YoungGandalf2325]

The next Sir David Attenborough of nature documentaries.

[@MrJdsenior]

Sort of.

[@KalebPeters99]

But somehow both more detailed AND more entertaining!

[@cloudforest4087]

My favorite way to learn about the intricacies of the animal kingdom.

[@Keish03]

Your videos are always such a treat 😌

[@jon-lucysart6284]

I've been waiting so I can watch this whilst high, on life.... anyhow thanks! Your a legend.

[@TEHDUDEMAAN]

I hope one day Ze Frank makes a True Facts on Ant-Lions. Probably one of my more favorite interesting bugs.

[@metalmamasue3680]

Idk if you saw zefrank's video about leafhoppers, but it was excellent 😂👍 Killer Surfing snails was great too, all of them are awesome.

[@annabrandberg]

So I just found out about the The Vampire Squid from Hell (Vampyroteuthis infernalis) and naturally the first thing I did was to check if @zefrank had a video on it - but unfortunately he does not... Where does one submit animal video requests? We need a "True Facts: Vampire Squid" video!

[@metalmamasue3680]

I know I'm going to look it up over coffee 😎🤘 thanks, I love how metal nature can be 😅

[@simonevernon106]

If I’d have had a teacher like you, I would have listened more!😊

[@shemarwhiteman8460]

I love the comedy aspect of all your videos

[@matthewsykes4814]

Nature never ceases to amaze me, even the tiniest of things are more complex than you would think at first glance. I love the humour and narrative. How about a deep dive into this entity known as "Jerry"?? 12 minutes of wonder and laughter, amazing. I honestly thought the video was longer I got so caught up in it.

[@hyperfocused7029]

Just when I thought Ze Frank couldn’t BE more entertaining, he adds sound effects for bodily functions that are weirdly adorable.

[@bendafyddgillard]

It is good to end a short film on the wonders of coral by gently pointing out how we're killing them en masse. Appreciation also for the scientists and videographers who collected the information in this film.

[@hailalmightypower]

It makes me so happy that you continue to create wonderfully joyful videos all these years. Keep doing what you do my strange and glorious friend

[@Wnick1996]

Coral really is fascinating to look at, especially the more fleshy corals. That's why I love to get them for my nano tank

[@sammiej.5526]

I did NOT know coral produced eggs let alone had larvae. The more you know I guess. LOVED IT

[@akabutu7565]

God I love these videos, puts a smile on my face every time. Thank you for giving me a much needed giggle this morning.

[@ADogandHisBoy]

I still don't get why Netflix or some other streamer hasn't gotten this man under contract to make his own nature series. It would be so wildly successful, and could be made rather cheaply. Shows how creatively bankrupt the entertainment industry has become.

[@MrJdsenior]

Hear hear!

[@beadmore]

I'm sure he has been approached by a network but he (ZeFrank) may not be interested. Also he would have to be careful with his "creative" speaking voice and not offend.

[@pst5345]

I do not qatch Netflux. I'd rather have him stay here. Since Cleopatra Netflix can sincerely die in a fire.

[@molybdaen11]

Technically he has a comedian career, it's just not as popular.

[@AB-un4io]

We cannot let them coax ZeFrank into their cult!! They don’t deserve him!

[@Echoday2day]

This video has finally made me understand what is coral. You get told what its about but it still didn't click till you explained it (Thank you) on behalf of a environmental science student who didn't get it explained properly at uni lol

[@MsLeenite]

True facts + awesome photography = Ze Frank video. I hadn't realized I wanted to know all that about reef corals. Thanks!

[@HighLighterlines]

Wow! Gotta say the production of this video was amazing. Those images, footage and even diagrams were beautiful.

[@sjfanning7711]

Best ZeFrank description today - “Looks like an albino raspberry crossed with a sneeze”! What was ur favorite one?

[@viddork]

Definitely this one.

[@SavageColeTrain]

I love the videos we get every once in a while from Ze Frank. Found this channel from Reddit, and glad I did. Jerry rocks, and is hilarious. I don't give a damn.

[@lorencarlin2087]

I've said it before, many times, and I'll say it again, ZeFrank is one of the best narrators on the planet! If David Attenborough is ever exposed to sunlight, and goes up in flames, this man needs to take his place. While he jokes a lot, he could be a serious documentary narrator. His voice is just so very perfect! Kudos dude!

[@Smokeyjoedamanedamythdalegend]

As funny as this is it’s honestly great facts. I had no idea coral came from individual animals. I always assumed coral was like trees and just always there. The fact it’s alive is mindblowing, goes to show you never stop learning

[@nom3nnescio]

Trees grow too, you know? And are alive

[@EnabiSeira]

I love weird animals, but corals are a category on their own. Cool!

[@littledreamerrem7021]

As someone with a fear of worms, the noodles are terrifyingly fascinating.

[@Sonatengraf]

I've heard about entire reefs dying off due to coral bleach, but I wasn't aware corals are actually animals! Whoa

[@MareeCK2409]

Coral reefs are so important to the health of the environment. Such fascinating creatures too.

[@tokus64]

Zefrank teaches you more then an average biology professor at Harvard University.

[@humongousfungusamongus3871]

Always a great time with ZeFrank...ALWAYS!

[@jaynorris3722]

ZeFrank, you make life so much better. Thank you.
