Coral is such an interesting animal. Many individuals sharing a single calcium carbonate skeleton, forming an entire ecosystem out of it, and getting nutrients through photosynthesis via algea in their cells. There's just something so amazing about it all.
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
i’m coral restoration certified and visiting the coral nurseries is unreal. sinking down and just seeing about an acre of these huge probably 10 meter/33ft pvc pipe towers with little coral branches dangling off. artificial reef structures aren’t allowed here so they’re raised on the structures and then transported to the outplanting sites. scrubbing all the algae and competing coral off the corals and pipes is very fun! had a trumpetfish friend for a while once.
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 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.
By far the most distressing thing I've learned from watching your channel is the sheer number of creatures that have "just ejaculate into the ocean" as their breeding strategy. I don't need to think about that next time I'm down at the beach.
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.
@@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.
@@xitaris5981 old enough that youre no longer worried about them copying mindlessly and saying ass, bitch, dick, etc at school, more of a "youll know it when you see it" kind of maturity rather than a specific universal age
Ok, but- Have you ever had sex with a shy femboy neko who, allthough he is usualy very nervous and scared with people, feels totaly safe in your arms, giving you his entire heart and body out of deepfelt love and trust?
The coral venom is no joke. One of my friends in Hawaii cut his foot on some coral while surfing. He didn't know about it and got real sick. He had to go to the hospital.
The poor coral probably died because of the accident. I'm glad you're friend made it out alive! The toxin itself probably wasn't what sent him to hospital. But the bacteria present in coral mucus likely did. The bacteria are beneficial to coral, but can be toxic to humans.
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.
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.
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)
@@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.
@@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 have raised them for years, and you hit pretty much everything any hobbiest would need to understand, as well as making it entertaining, succinct, and accurate.
Do they grow only to the size of the tank or do you need to manually trim them down like an overgrown tree branch? Did you pair them with other sea creatures like a live mini biome in a tank.
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.
Wow! Incredibly good coverage of these amazing animals! I have raised them for years, and you hit pretty much everything any hobbiest would need to understand, as well as making it entertaining, succinct, and accurate. 10/10
You gotta mix in some fungi and slime molds to make a truly alien looking ecosystem. Granted they are all from earth but together they all seem very unique
I doubt you read all these comments, Zefrank, but just in case you do, thank you for continuing to upload and for all the content over the years. I've been following you for a long time. You are most definitely part of the OG TH-cam world. Thank you for everything.
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.
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...
@@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 The ocean fear is there unrelated to the coral. Its not the holes on them, its that they're alive and exist around me. Especially when they're not in my field of view. The best way I can describe my fear in the ocean is that it feels like something is coming up behind me at all times. And in the ocean "behind you" encompasses a much wider area. Looking down at the coral doesn't bother me so much., but existing near it when it isn't in my field of view sets me on edge. Knowing something is alive right next to me but I can't see it and when I'm not in total control of my movements really bothered me. I drifted into the coral thanks to waves at one point in the dive and I just about jumped out of my skin.
My friend introdused me to your videos almost 10 years ago, showing me the mantis shrimp video. I had never seen anything remotely that funny and informal videos about animals and nature, and that still holds up to this day. Thank you for your work. Your videos are always a pleasure to watch.
I used to share them with a Conservation group of scholars on FB, they absolutely Ioved them. The kiIIer surfing snails and nudibranchs were favorites 😊 although they enjoyed every one of them.
As someone who keeps a saltwater tank filled with lots of coral, I found this to be the best video yet and still managed to learn something. Great job! 👍
I’m one of the reef keepers who’s lucky enough to have my corals spawn in a captive environment multiple times. It’s a truly beautiful thing to witness right in front of your own eyes, although it kinda makes the phosphate level go through the roof the next day and I have to do a big water change lol
“Because everything has to be complicated” what a mood. Absolutely love these videos these are the highlights of my day whenever a new one comes in and it’s just so fantastic and the sass. And Gerry. We love Gerry
I knew that there was a lot more going on with coral that you can't normally see with the naked eye, but holy crap there's A TON that you can't normally see! Let's join forces with the science hippies & save these little tic tacs! As always awesome video dude. Thank you for your videos. My wife & I love them. You & Jerry keep rocking!
@zefrank Everything I know about coral reefs I learned from you. The visual presentation & your “layman’s” narration kept me glued with interest. Thanks for the enlightenment.
As a company that grows coral to restore dying reefs, we can confirm that this video, ZeFrank, and corals rock 🪸 Animals with plants inside them that make rock for their skeleton
Thank you for posting this! Coral bleaching is such a serious problem, I've been studying a way to reduce it's effects by essentially putting up an umbrella on them. Hope my paper gets published soon.
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.
One hopeful note on coral bleaching is that a small percentage of organisms within some coral species are now able to withstand higher temperatures without bleaching, so if those corals can spread at least some reefs might avoid extinction.
Reef restoration projects make use of this fact, deliberately introducing the more resilient zooxanthelle (the algae dudes) to corals around the world.
@@brianaschmidt910 It’s like humans never grow out of the “I am the universe” thought processes of infants. Babies also resent having their diapers changed, believing it’s their own “special creation!”
I discovered that this is the case with sea urchins, too; there are varieties that are adapting to the warmer/more acidic conditions to survive the changing conditions. (It inspired a poem on the anniversary of my husband's death.)
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! 🙂
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.
I grew up with salt water aquariums, and always wondered how coral was a living creature. They looked like rocks with a weird moss on them! Thank you for this very close look at them. It's so sad that they're dying off.
Usually, I'm afraid of corals (basically all cnidarians and most of sea invertebrates) but this video wasn't as scary. At some point, you just get used to the fact that we have eldritch horrors living just under the surface of the water. They're colorful and pretty!
Eldritch has a tendency to describe a good 20% of sea life coral is probably the least Eldritch thing in there ( besides the whole carpet with multiple mouths thing)
@@SuziQ. don't forget 90% of anything lower than 4000 metres below sea level, especially the eals. Seriously, there are 3 levels to the midnight zone, and one of them is literally called the abyssal zone, and I'm pretty sure hp lovecraft just asked God if he could copy his homework from there
Of all the things in the sea that are legitimately terrifying, you’re afraid of coral? Other cnidarians like starfish and urchins I can understand. But I guess under a microscope, those little polyps are pretty freaky. Like something out of pre 2000 horror film.
@@ScorobeSlavinpoop they are prehistoric, alien looking things and apparently their blood is worth more than gold. Hopefully @zefrank will see the request!
@@molybdaen11, I spent my first 18 summers at my parents cottage on the shores of Long Island sound and we used to see the horseshoe crabs come ashore to mate every year. They are indeed very cool. A few locals would crack them open and use them as bait in their minnow traps but I always felt sorry for the crabs. Nowadays scientists take samples of their blood for use in medical research, but the crabs are returned pretty much unharmed to the ocean.
@@goodun2974 I only know them from the internet. In the Baltic Sea we only have small shrimps. They look so alien with they big shell and dangerous stinger.
@@molybdaen11 , The stinger isn't dangerous at all, unless you pulled one from a horseshoe crab 😭 and attached it to a pole to use as a spear. They're not at all like stingrays and nobody I hung out at the beach with ever got injured by stepping on one.
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.
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)
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.
you are my number one favorite channel on youtube, the frist yt video i ever remeber watching was teddy gets an opetaion and since that came out i've watched everything you've made. thank you for your presence!
I have adopted ZeFrank's pronunciation of the word "baby" and now say "beh-beh" continuously, in his honor. Watching the baseball, I say, "That's right, beh-beh!!". No one sits near me on the bus.
I used to watch this channel back in the day and have rediscovered it all lately. I'm so happy to see so much more support from the scientific community. You get the best support. I love these videos. And you do soooo much work on every one!!! Love it!
Thank you! Its truly a pleasure to click, sit back, and just watch! The mix of education, witty one liners, and quality video - I don't even bother reading the title - if I see its one of your videos - I'm happy to finally have something good to watch!
Omg yes. I somehow missed this when it first came out, l was thinking, Gee it's been awhile since l've seen a zefrank video and here I missed it. Dang ScrewTube not giving me a notification. Oh well, now I know I can expect a new one in 2 weeks 😊❤
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.
I never knew about corals predatorial habits or territorial disputes for lack of a better term. Not often I get just flat out new info on TH-cam, let alone with such good video to accompany it.
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!
I’ve been on dives that looked aquatic wonderlands and I’ve been on dives that looked like those at 10:40. That was 15-20 years ago. I don’t want to know what they look like now.
For me, this must be the most amazing video you have ever made. I have always considered corals to be the strangest form of life on earth, and you just summed up years of marine biology in several hilarious minutes. You are a gift to education by quickly demonstrating just what is so fascinating about biology. Keep it up!
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.
I always love these marine animal True Facts because I showed my marine biology teacher in high school a ZeFrank video & he showed a bunch to the class as assignments 💀
The algae specifically are called zooxanthellae (zoo-zan-thay-lay) and their symbiotic relationship benefits the algae as well as the coral. The coral provides a safe place for the zooxanthellae since they reside in coral tissue. They are less susceptible to predation by zooplankton. Also the mucal layer of coral is very sentitive to disruption through touch. If you carelessly touch living coral, you can disrupt the mucal layer and infect the coral with bacteria.
I watched a video about saving coal. They put tents over Coral before they spawn, capture all the gametes and then they mix them in the lab and they have about a 99% fertilization rate and then they reseed (if that's the right word) them back in the ocean. Super cool
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!

“Because everything has to be complicated” what a mood. Absolutely love these videos these are the highlights of my day whenever a new one comes in and it’s just so fantastic and the sass. And Gerry. We love Gerry
6:00 Frank deserves a respectable raise just for those golden mouthing noises
I knew that there was a lot more going on with coral that you can't normally see with the naked eye, but holy crap there's A TON that you can't normally see! Let's join forces with the science hippies & save these little tic tacs! As always awesome video dude. Thank you for your videos. My wife & I love them. You & Jerry keep rocking!
I've been keeping coral in reef tanks for over 20 years and those close up shots we're amazing! And ridiculously hilarious! 🤣
@zefrank Everything I know about coral reefs I learned from you. The visual presentation & your “layman’s” narration kept me glued with interest.
Thanks for the enlightenment.
Imagine if Jerry was able to get that old buzzard Creepy Dave on this show. He'd be producer of the year!
That would be awesome 😎
I like them separate
Creepy Davis is a vulture >:(
@@excusablehoneybee4599, Buzzard = vulture.
I prefer the long content like this. Can only take so much of Creepy Dave at any given point in time. :D
This was the best explanation of coral bleaching I have seen, and now I understand it better. Thank you!
As a company that grows coral to restore dying reefs, we can confirm that this video, ZeFrank, and corals rock 🪸

Nice! Thank you for the good that you do.
thank you for your contribution. but how exactly does one turn a profit doing that, might I ask?
@@benthomason3307 Not everyone is out there for the profit, bud.

@@Rockribbedman Nah… props to Jim Jeffries, but it’s more of the Good Barrier Reef these days at best
Thank you for posting this! Coral bleaching is such a serious problem, I've been studying a way to reduce it's effects by essentially putting up an umbrella on them. Hope my paper gets published soon.
If it's a temp thing as well, have you tried dumping out buckets of ice on a regular schedule?
Just don't inspire anyone to tow chunks of the Great Pacific Garbage Patch over there.
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?
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.
Great narrations, even sillier sound effects! I learned some things and laughed too. Thank you Ze Frank! 🙏
One hopeful note on coral bleaching is that a small percentage of organisms within some coral species are now able to withstand higher temperatures without bleaching, so if those corals can spread at least some reefs might avoid extinction.
Reef restoration projects make use of this fact, deliberately introducing the more resilient zooxanthelle (the algae dudes) to corals around the world.

It’s like humans never grow out of the “I am the universe” thought processes of infants.
Babies also resent having their diapers changed, believing it’s their own “special creation!”
We have to die out first so those survivors can regenerate
I discovered that this is the case with sea urchins, too; there are varieties that are adapting to the warmer/more acidic conditions to survive the changing conditions. (It inspired a poem on the anniversary of my husband's death.)
What's even cazier about animals like coral, jellyfish, and sponges is the fact that they've been pretty much around since the dawn of time
Dawn of multicellular life maybe?
Dawn of time: 13787 myo
Earth forms: 4540 myo
Life: 3800 myo
Coral: 535 myo
So has pretty much every other animal if you're a young Earth believer (religious or otherwise. )
We keep digging up older and older rocks and then some science-hippie says, "you know this formation here kinda looks like a cnidarian..."
@@timwoods2852But this is a science channel. We don't do religion here.
For example: the age of the earth is not a matter of belief!

I learned more about coral in 10 minutes than I ever saw or read. Congratulations!
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! 🙂
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.
Because they don't get paid enough!
I grew up with salt water aquariums, and always wondered how coral was a living creature. They looked like rocks with a weird moss on them! Thank you for this very close look at them. It's so sad that they're dying off.
Usually, I'm afraid of corals (basically all cnidarians and most of sea invertebrates) but this video wasn't as scary. At some point, you just get used to the fact that we have eldritch horrors living just under the surface of the water. They're colorful and pretty!
Eldritch has a tendency to describe a good 20% of sea life coral is probably the least Eldritch thing in there ( besides the whole carpet with multiple mouths thing)
@@someoneudontknow3709, True. The stinging ferny, ferny hydroids and certain crabs, fireworms, and seahorses come to mind.
@@SuziQ. don't forget 90% of anything lower than 4000 metres below sea level, especially the eals.
Seriously, there are 3 levels to the midnight zone, and one of them is literally called the abyssal zone, and I'm pretty sure hp lovecraft just asked God if he could copy his homework from there
@someoneudontknow3709 I think a flesh carpet of mouths, tentacles, and intestines, sitting on top of skeletons, is pretty eldritch.
Of all the things in the sea that are legitimately terrifying, you’re afraid of coral? Other cnidarians like starfish and urchins I can understand. But I guess under a microscope, those little polyps are pretty freaky. Like something out of pre 2000 horror film.
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
Another fantastic video! Can you please one day get to horseshoe crabs? Those are fascinating creatures!
@@ScorobeSlavinpoop they are prehistoric, alien looking things and apparently their blood is worth more than gold. Hopefully @zefrank will see the request!
Ah yes the horshoe crab: refusing to evolve for 300 million jears and sole reason we can detect bacteria.
@@molybdaen11, I spent my first 18 summers at my parents cottage on the shores of Long Island sound and we used to see the horseshoe crabs come ashore to mate every year. They are indeed very cool. A few locals would crack them open and use them as bait in their minnow traps but I always felt sorry for the crabs. Nowadays scientists take samples of their blood for use in medical research, but the crabs are returned pretty much unharmed to the ocean.
@@goodun2974 I only know them from the internet.
In the Baltic Sea we only have small shrimps.
They look so alien with they big shell and dangerous stinger.
@@molybdaen11 , The stinger isn't dangerous at all, unless you pulled one from a horseshoe crab 😭 and attached it to a pole to use as a spear. They're not at all like stingrays and nobody I hung out at the beach with ever got injured by stepping on one.
Thank you, Ze Frank. This one is so important and so to the point. I've never heard coral bleaching better explained for a general audience.
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
You still have half of the break break left
Wow! Gotta say the production of this video was amazing. Those images, footage and even diagrams were beautiful.
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! 😱
Your videos are always such a treat 😌
I can never wrap my head around the fact that corals are animals and yet they look and act like plants
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.
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)
IMO they operate more like a fungus or a really lazy ambush predator.
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
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.
This is definitely the best thing to watch while recovering from a chest cold
"lung biscuit", I'm dead..🤣☠️
This man really do be reading mucus literature on a Tuesday afternoon.😂
Thank you for all your full length content. I don't know what the internet would do with out you
Fascinating! For some time I'd wondered exactly what coral was, never sure if it was an animal or a plant. Now I know it's a Cthulhu.
you are my number one favorite channel on youtube, the frist yt video i ever remeber watching was teddy gets an opetaion and since that came out i've watched everything you've made. thank you for your presence!
I have adopted ZeFrank's pronunciation of the word "baby" and now say "beh-beh" continuously, in his honor. Watching the baseball, I say, "That's right, beh-beh!!".
No one sits near me on the bus.
I used to watch this channel back in the day and have rediscovered it all lately.
I'm so happy to see so much more support from the scientific community. You get the best support.
I love these videos. And you do soooo much work on every one!!!
Love it!
As always hilariously educational
Thank you! Its truly a pleasure to click, sit back, and just watch! The mix of education, witty one liners, and quality video - I don't even bother reading the title - if I see its one of your videos - I'm happy to finally have something good to watch!
Omg yes. I somehow missed this when it first came out, l was thinking, Gee it's been awhile since l've seen a zefrank video and here I missed it. Dang ScrewTube not giving me a notification. Oh well, now I know I can expect a new one in 2 weeks 😊❤
Man this armored core 6 lore vid is wild
Every time a pleasure and a discovery. Ze you are priceless. Thank you! 🧡
Incredible footage & wonderful explanations. Really feel like I've gained insights on coral!
ZeFrank has such a knack for giving us educational AND hilarious videos of the weird living things that we share the planet with
No matter my emotional state,zefranks videos always cheer me up!😊
True facts + awesome photography = Ze Frank video. I hadn't realized I wanted to know all that about reef corals. Thanks!
I love the comedy aspect of all your videos
Zefrank doing a coral video!? 1 more off the bucket list! Thanks guys!
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.
I never knew about corals predatorial habits or territorial disputes for lack of a better term. Not often I get just flat out new info on TH-cam, let alone with such good video to accompany it.
God I love these videos, puts a smile on my face every time.
Thank you for giving me a much needed giggle this morning.
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!
I’ve been on dives that looked aquatic wonderlands and I’ve been on dives that looked like those at 10:40. That was 15-20 years ago. I don’t want to know what they look like now.
I love you. I’m having an exceptionally rough day, and this put a much needed smile on my face. Thank you ❤
I hope one day Ze Frank makes a True Facts on Ant-Lions. Probably one of my more favorite interesting bugs.
Idk if you saw zefrank's video about leafhoppers, but it was excellent 😂👍 Killer Surfing snails was great too, all of them are awesome.
I was waiting for you to make one on corals ! Thank you ❤
For me, this must be the most amazing video you have ever made. I have always considered corals to be the strangest form of life on earth, and you just summed up years of marine biology in several hilarious minutes. You are a gift to education by quickly demonstrating just what is so fascinating about biology. Keep it up!
absolutely hilarious a "Lung Biscuit"! I just adore how very intelligent you are all the time; you are so darn inventive! Thank-you!
Thank you for finally covering coral! I have a nano reef tank that I love.
"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.
Yeah, underrated.
Always a great time with ZeFrank...ALWAYS!
'Coming across the wig of a drowning clown'. Now that is just poetic.
I will never tire of ZeFrank’s sound effects
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.
I always love these marine animal True Facts because I showed my marine biology teacher in high school a ZeFrank video & he showed a bunch to the class as assignments 💀
I did NOT know coral produced eggs let alone had larvae. The more you know I guess. LOVED IT
Thank you so much! What a great teaching material ❤❤
As usual the best mix of awesome, creepy and disgusting! I love Ze Frank videos! So full of curiosity.
I feel better about the world, knowing that there are entire organizations centered around saving these beautiful keystone species of the ocean
That fish is adorable. I don't blame Jerry one bit for wanting to use that footage.
Your footage skills are on point. Always have been, but this one's fantastic.
The algae specifically are called zooxanthellae (zoo-zan-thay-lay) and their symbiotic relationship benefits the algae as well as the coral. The coral provides a safe place for the zooxanthellae since they reside in coral tissue. They are less susceptible to predation by zooplankton.
Also the mucal layer of coral is very sentitive to disruption through touch. If you carelessly touch living coral, you can disrupt the mucal layer and infect the coral with bacteria.
I watched a video about saving coal. They put tents over Coral before they spawn, capture all the gametes and then they mix them in the lab and they have about a 99% fertilization rate and then they reseed (if that's the right word) them back in the ocean. Super cool
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!
I know I'm going to look it up over coffee 😎🤘 thanks, I love how metal nature can be 😅
Even your commercials are just ...Brilliant. nice work
Mr Frank.👏🏼👏🏼
Ze Frank is a gosh-darn international treasure, and that’s better than a plain _national_ treasure! 🐠🐙🐬🦀
Yay! Love getting an alert from Ze Frank! Makes everything better! ❤🤗❤🤗
I love weird animals, but corals are a category on their own. Cool!
Thanks for helping out the Coral, Ze Frank. Under-rated little fellas!
Poor Jerry. ZeFrank told him not to write metaphors, and he didn't; he wrote a similie and still got blamed. Poor, poor Jerry...
