The Fascinating World of Cnidarians
Vložit
- čas přidán 31. 05. 2024
- The phylum Cnidaria contains such creatures as jellyfish, anemones, siphonophores and corals. Together, they consist of around 13,000 living species - surprisingly simple, yet beautiful organisms. The importance of these cnidarians cannot be understated. Coral reefs are formed of many millions of cnidarians and are home to staggering biodiversity. Jellyfish are important predators in the open ocean food web, but they serve as food for many other species as well. Sea anemones fulfil a similar role but in the shallows, also serving as hiding places for clownfish. Thus, this unique and abundant group of creatures is integral to the function of many marine communities, from the open ocean to coasts and the benthic zone of the deep sea.

THAT WAS SUBNAUTICA MUSIC. ITS PERFECT
Yes it was!!!!! 😂 I’m so pleased someone recognised it, I figured it’d go hand in hand with a film about creatures that look like they’re straight out of 4546B
I completely agree it added so very much to this amazing video!!
When I noticed that I got so hyped
The music was ringing on my head then i see your comment
Good job Bois !
I never realised corals and and jellyfish fit under the same category, they look so different at first glance
Corals don’t even look like animals
Thats what they want you to think
@@thelordnaevis4946 Yeah. The coral reefs are actually the leftover bodies of the coral, I think...the coral is the colorful stuff on them.
I think they just never left the polyp stage.
@@alluceoave💨 Who's "they"......... 🖐😲
I am studying to become a Marine Biologist, and I exclusively study Cnidarians (primarily Corals and Anemones). Thank you so much for creating this magnificent and breathtaking masterpiece! You have created one of the most outstanding and informational channels on this whole platform. There’s almost nowhere you could see this amount of biodiversity in one video about Cnidarians ANYWHERE on the internet. Good job and please continue doing what you do! Human beings need to learn and appreciate these little known organisms as much as we possibly can, they are one of (if not the most) important phylums in the whole entire Ocean. And have been for over 500 million years.
That’s so lovely of you, thank you for watching and taking the time to leave such a motivating comment. I begin my own Marine Bio studies this September and can’t wait to start, how are your studies going? Cnidarians are some of the most biologically bewildering organisms on Earth, it must feel like you’re studying alien life half the time considering how their anatomies, behaviours and physiologies are unlike those of any other organisms!
Best of luck to you enjoy your awesome career choice 👍
So true. This channel is awesome
This is extremely random but I’ve always really wanted to become a marine biologist when I’m older, were there any classes or things you learned In high school that were helpful with your studies?
@@poopfart3904 Since nobody replied to you yet… yes. In general knowledge in chemistry and biology is always helpful for your start studying biology or marine biology later. Also enjoying traveling and to get to know new places and cultures is an advantage. However you dont need to have the best grades in high school to become a marine biologist. Its more about passion and about spending a lot of time becoming an expert in one specific topic and to collect the scientific data. In my opinion the best possible start in high school would be a gap year in another country and solid interest in natural sciences
I appreciate that these are just facts without mentioning current world issues, that are ultimately depressing. Learning about the world's creatures and geography in itself is so fascinating and provides a great escape from my day to day reality.
Co2 emissions
Yeah good job bringing that up, I almost forgot how shit our world is. Thanks a lot.
*@Bliss Opulence* All good and well, but don't forget the U.S. became a one party state after november '63 ,
where both allowed parties serve the Pentagon first and foremost. Allowing its annual biggest percentage share from the people's treasury , no questions asked . Which usually is the privilege of military regimes.
All with "God's" Blessings" ofcourse .
Couldn't agree more. Sometimes I just want to learn about a cool sea creature, and it feels like a bummer when the video mentions how the animal is in danger or something. It's important for sure and I want to get a job in conservation, but its important to learn and not have it be depressing.
You got to face the music sometime. Sticking our heads in the sand and pretending everything's fine is why the world is so shit.
One of the best CZcams channels you gotta use this as an asset when you apply to university
Thank you!! Funnily enough, I have my first A-level exam today. If I get good in these, I’m off to study marine biology in September 😁 really appreciate your kind words my friend!
@@NaturalWorldFacts aw that is awesome, i just stumbled across your videos and I have already watched so many. I am a Biology major in my second year! Good luck with your future endeavors!
@Francesca Troiani Aw that’s really sweet of you, thank you for being so supportive! I can’t wait to begin my studies 😊
Best of luck to you too with your Biology course! And welcome to the channel.
Wa
So a correction, it's not an immunity the clownfish has. It actually builds up an amount of the toxins and such the anemones emit, into the natural slime coat that all fish have, and the anemone no longer recognizes it as a fish and things it's just part of itself. They can't just go around to any old anemone
My God, this channel is above all. The production level is insane and that narration is just too good. The learning is enjoyable. The narrator should be rewarded...
I see graceful angels & Hell-fire! @1:14+
I think the reverb on his mic is really annoying though but I guess I'm the only one here XD
@@Love-jf7rs what
Leo, I’m simply amazed. Every time you upload a video I’m overwhelmed with incredible editing, a wonderful atmosphere, and an amazing narrator who I know puts absurd amounts of effort into weekly videos for free. I saw in another comment that you had an A-level exam, and I sincerely hope you did well because the world needs more marine biologists and you are an amazing candidate to be one. I wish you only the best in life because everyone here knows you deserve it.
That’s so lovely, thank you for always being so kind and supportive, it means the world to me! I’ve now done 6 A-level exams out of 9 so far, and I think they went well. I’m so eager to start studying marine biology and to share that journey with you, and I wish you all the best in life too! It’s comments like yours that keep me going and make me excited to work on new videos!!
I can't sleep a lot of the time, and i have a pretty physically demanding job so it can start to add up and weigh on me, but your voice and obvious love for creating is so relaxing to me. i never found animals as interesting as things like space or plants, but now ive found a new love for oceanic life and i realise how miraculous it all is. thank you for sharing your love with me, and everyone who also watches and loves all of your efforts
Such a great video! I’ve always been fascinated by cnidarians in particular. They seem so other-worldly yet so simple. Beautiful creatures.
Thanks! And I couldn’t agree more - for creatures so anatomically simple, their ecological niches are remarkably complex, and they look so alien
Narrator's voice gives me ASMR and I
this is currently my favorite channel. i’m an art student but looking at all these different marine life forms is strangely calming and inspiring. thank you for the high value and i look forward to your future endeavors!
Aw thank you so much!! I hope your art studies go well :)
I've been following the B1M channel for months now, fascinated by their narration, skills in writing and editing, and their overall superb quality. As a Biotechnology student, I've been looking for a natural-sciences-based channel with their level of quality for a long time.
I've finally found it. This is the B1M of Biology.
Thank you so much!! That’s an incredibly motivating comparison, I love B1M. Welcome to my channel :)
I love how much teamwork and trust that other sea life has with Cnidarians. It's so incredible to see. Thank you for this video!
Let me save you some time, song is:

I didn't expect its combination with the content to be perfect. A surprising find. I love it.
Cheers :) LEMMiNO is a CZcams God!
I’m eating popcorn watching this like it’s endgame lol I love this
This was much needed change of pace after studying for CURSED mathematics all week long 😭
I hope it went well, and I’m glad the video was a nice break for you! I just sat a chemistry exam 😳😳 biology next! What about you?
@@NaturalWorldFacts Well..... Everything 😅
I’m working to get my GED by August so I’ve been studying like crazy all the time.
Especially on everything involving math because to tell you the truth it’s my worst subject and I can’t take any chances on messing up. 😂
Keep at it, I’m sure you’ll do brilliantly. Where do you want to go if you get the qualifications you need?
@@NaturalWorldFacts I’m from Texas so probably Tarrent County College or somewhere similar lol. Though I’ve always wanted to travel and maybe go to University somewhere else!
People here have a habit of staying here their whole lives and never really going anywhere else 😅
That’s so exciting. Whatever you do and wherever you go, I’m sure you’ll have an incredible time :)
Good luck in your exams!
The moment I heard Lemmino's Cicada 3301, I stopped all action to listen to how Portuguese Man o' Wars eat food with all my attention.
I am so thankful that god of a youtuber lets others use his tracks!
@@NaturalWorldFacts The more I watch your videos, the quicker you're becoming one of my favourite channels. Love your work.
P.s. watching more of your videos has made it clear that your music choice is super fine.
Thank you so much! That’s so awesome to hear, especially considering I started this as just a hobby. I really appreciate your support :)
Also, cheers, finding and editing to music is my fave part of editing!!
czcams.com/video/SdZIiBLtWf4/video.html
I love lemminos channel
You know, your voice is pretty soothing and I think fitting for a channel like this. Actually feels like official documentaries on National Geographic. Keep it up.
More like Sr. Attenborough and BBC-Earth..:) This is by far my favorite channel of this kind! :)
Super interesting!! The music and editing was done really well, felt like I was watching a professional documentary. Plus, I freaking love this type of chill informative content, and you’ve got it down pat- lol. Keep it up!!!
Thank you, that’s so lovely of you!! I love making them so it’s awesome to know you enjoyed it :) there are many more yet to come!
Whom ever does the narration of these gorgeous films has the most ethereal lovely soft perfect voice for not just these topics , but for narration in general. This beautiful voice adds the most quintessential touch to these already gorgeous videos. ❤
The most beautiful phylum. One would never guess all these creatures related.
czcams.com/video/SdZIiBLtWf4/video.html
Please never stop creating this content.
I usually have these documentaries in the background when doing something, and that I heard Subnautica music and was like "Dam, that's some quality production here".
To anyone who's suffering depression, anxiety,insomnia and other mental health problems, you are not alone. I feel you. You are so brave. You are doing so well. I'm proud of you. I'm sending you a virtual hug
your videos are NOT LONG ENOUGH i could sit and watch this stuff for literal days, tell me about cnidarians in the benthic zone, or how they evolved or detail cool species that warrant their own section, please i dont care what you talk about i just demand more, subscribed.
Aw thanks so much!! I’ma just leave the full series link here, there are many more to come 😉 czcams.com/play/PLKzq2xKdfIot0rJTxkzPG7srMQm0sSeIG.html
Recently, my favourite thing to do when I cant sleep at night is to just listen to your videos. The visuals are amazing, but I love that they aren't 100% necessary to understand the video, and your voice is super calm and soothing.
Your videos are perfect for making sure that I don't get over stimulated, but I'm not stuck all bored at night! ❤
This was so lovely to read. Thank you for writing this, you’ve made me smile - really really glad you enjoy my vids :)
Your voice is amazing, like wow! So soothing
Thank you so much 💛
This is so far the best video of cnidarians I've ever seen! Amazing!!! Congratulations for your work!!!
Thank you so much Igor!!! That really means a lot :)
This is my new favorite channel. Thank you so much for existing. The level of independent production quality available for free on the internet today is absolutely astounding. I love it. Thank you.
The video is great, such a soothing voice, but the cutest thing is looking through the comments and seeing the creator respond to people :,)
getting to watch your videos for free is a blessing
This channel has been such an amazing thing for me to find. It isn't only so interesting and incredibly well produced, it is very calming. Whenever I'm coming down from a panic attack, or have too much trouble sleeping, these videos help me relax enough to function or sleep.
So thank you, keep doing such a beautiful job
Thank you so much! I’m so so glad they help put you in a calmer frame of mind, I know how awful panic attacks and loss of sleep can be! I really appreciate the feedback :)
The man's posting since 2012. You can see him quite LITERALLY grow from the start. It's just so amazing..
This channel has been my number 1 source for deep sea information
The world needs more of these videos!
Here, have more :D czcams.com/play/PLKzq2xKdfIot0rJTxkzPG7srMQm0sSeIG.html
@@NaturalWorldFacts thanks! 💜
My lectures are often a bit full on with a lot of details about the phylum we’re studying, but this honestly helped me ease into learning about cnidarians before my lectures bombarded me with information. A lot less confusing and a lot more understanding. Thanks a bunch!
Cnidarians have been my favourite animals since I was a child.
omg the way that jellyfish move makes me instantly calm and almost hypnotized me
Don't mind me I'm just gonna binge watch all these beyond amazing videos.
Who needs BBC or Planet Earth when you’ve got THIS channel! 😍
Hey nice vid I haven't been here much cuz I had exams but they finished now😊
Heya!! How did they go? I’m sure you did very well :D
@@NaturalWorldFacts yea they are good but the English one was abit hard but other than that they're good thanks for asking
That’s really good! Especially after such a strange and disrupted year of education
YES, LOVED THIS VIDEO! and not to mention the Subnautica music! ... PERFECTION!!
Ayy thank you :)
This channel is mysterious magical and mystifying! I keep clicking on more videos! The way you calmly speak, the way you properly pronounce words I couldn’t say if my life depended on it, the gentle music in the background, good editing, and how informational and correct everything that you’re saying is. Please keep posting more I love your channel!
I could watch hours and hours of documentations like this. Nice voice, amazing pictures and so much to learn
Aw thank you :)
This Channel came randomly and oh Boy was this worth It !!!
Deep Sea is fascinating, and this reminds me of my childhood documetaries...
Awesome job my friends !!
Thank you so much!! This started as a little hobby of mine so the response it’s had has blown me away!!
I loved the format of this video, so many complicated words but with their own written spelling and definition. Also the narrator voice was so relaxing and captivating. 10/10
This channel has reignited my love for marine biology, thank you so much :)!! It’s insane how high quality and engaging these videos are
Outstanding video. Soothing voice of the narrator and chill music to go along with it. Has to be one of my favourite videos here on CZcams. 💜
I viewed about 4 of your videos, I was sure it was a big company, like Nat Geo. Fantastic content. So underrated. You've earned a new sub bro, keep up the great content!
Aw thank you so much!! Just little old me, no big company, but I’m so so honoured I could be confused with one 😁😁
I'm way too stoned for this. How do I even create content that competes for views with this as a creator myself? This entire presentation was like being blasted off onto another planet. Mind blowing stuff. 🤯
I find the life cycle of them so amazing. Like insect metamorphosis, they completely change their appearance and for jellyfish, one polyp turns into multiple medusas. Really makes you question where one animal ends and the next one stands. The same with syphonophores. By the way, have you heard of the jellyfish lake on Palau? It's a lake that is so isolated from other bodies of water that the jellyfish living there have lost their toxicity, so it's harmless for humans to touch them. But reaching the lake is difficult.
i'm actually having a breakdown right now, in the middle of the night. Your voice is calming me a bit because it reminds me of something... i dont know what, but it's calming me. thank you for your videos
awh thanks for making this! i love it so much, and the seaworld has a special place in my heart trully.. they are just amazing and bizzare, you can found things you cant even imagine it with ur own head
The Facinating World of Cnidarians documentary is a great movie to watch for marine and nature lovers. In this production they paid a particular deep atention to the facinating details of the life of these normally unknown beings. The way that the producers conducted the video makes the learning enjoyable. The subaquatics images with all the Cnidarian's beauty was really breathtaking. I dicovered a world much more interesting than I already knew! If you love to be surprised this documentary is an absolutely way to reach this point.
cannot really understand how you have been at this for so long and not reached 100k subs at least. this channel is seriously underrated
Thank you so much!! I started 10 years ago in my bedroom 😂 its incredible the response it’s had lately, I’m blown away
the soft reverb on the narration is just *chef's kiss
I am under 15 and obsessed and fascinated with Cnidarians, when I am older I was to study in marine biology, specifically cnidarians these type of videos are my favorite!
What an amazing and high quality video… I’m still in awe. So much information packed in such a Great piece of video… thanks a lot.
I did a presentation in grade school on these, nudi branches, and octopi. They're such fascinating organisms.
This was utterly fascinating and really well put together! It was informative while also very entertaining. Thank you!
your newest video is probably the most stunning visually and best crafted videos ive ever seen on youtube. keep it up man i love whatre youre doing here and the music you use is impeccable and transforms the information youre providing us into a beautiful craft. cheers
This is awesome! Different kinds of jellyfish take up a large portion of my "favorite animals" list. They're so gorgeous! It's awesome to know that they're also integral to the ocean's communities. The haunting Stygiomedusa, smacks of lil' moon jellies, and stunning Pacific Sea Nettles are just some of my absolute favorites.
Thanks for posting this!
The jellies of this sentient smack are ever-grateful :))
I love the narration in these videos, like the voice is perfect for the topics and really well-done :) (and also really soothing to listen to 0-0)
i love your channel so much! it helps me a lot because its so organized and straightforward. timestamps, playlists, etc. its all so helpful! and all your videos look so nice and you explain things so well.
Thank you so much, I love organising and planning the videos, I have a desire to make everything neat for some reason 😂 really appreciate the kind feedback
Dude I really love your channel, it’s like so soothing and it makes me fall in love all over and over again with marine life and its science, thank you for such gifts of information ^^
This is so cool! Thank you for formatting this video in a way that makes the information easy to understand. This would definitely be a good resource for schools.
I saw this video for a project for school, but it is very educating 💖❤
A GREAT VOICE!!!! THAT ECHOS ALMOST, TO REVEAL THESE AMAZING SEA CREATURES FROM THE OCEAN DEPTHS . BEAUTIFUL PRESENTATION. THANK YOU.
much funkier music in this video than in others! less peaceful, but also probably more appropriate for shorter videos. LOVE this channel
just found this channel and im in love! subscribed bc now i wanna learn everything about the ocean.
i just got this in my recommended and watched it all. ive never really watched any videos like this before
So happy to see this channel blowing up 🙌 these videos are just so mint
Thank you!! That really means a lot 😁
I've just had my lecture about cnidarians in class and I want to thank the video for providing all that increadible footage. The narration and music are beautifully done.
Two things that makes me happy about this.
1. I love the ocean and always enjoy learning about them.
And 2. They used a Subnautica soundtrack
This is the last evidence I needed. Jellyfish are now my favourite animals. I never knew the answer to the question but these... they're just too beautiful and interesting
This opening monologue has real “LoTR fellowship opening” vibe and I’m here for it
This was the most relaxing educational video I've ever seen.
My friend,
Wonderful video again and you would also make a great vampire with that voice of yours 😄 Also your background music have improved.
Thanks Claude! 😁
Okay, this was such a beautiful video. Thank you!
I was today years old when I learned that jellies, anemones and coral are all cousins. Thank you for this info, I actually needed it for a fantasy story I'm creating but even if I didn't need it, it's still cool to learn this stuff
Dang, this channel needs more subs. This is top notch content.
This is absolutely gorgeous.
Thank you❣️
Excellent UHD picture and high quality sound. The makers do their amazing subject justice.
This is amazing! I love this channel. So informative and fascinating and aesthetically pleasing to listen to and watch!
Thanks!! You’ve made my day :)
Your videos are great to fall asleep to.
The narrator voice is so therapeutic and perfect in tone.. I love going to sleep listening to her speech..
Genuinely excellent narration, and the video is great!
I can listen to this narrators voice, all day all night.
I love these videos, it’s the perfect thing to watch at anytime, my career if I could choose would be either a marine biologist or a hematologist
This was brilliant! So interesting; brilliantly narrated and shot. Thanks!
Very beautyful vedio lovely under sea water creatures are seen the sea field.
5:38 I’ve rewatched this transition several times, there’s just something about it that brings me peace.
Considering these guys are literally one of the oldest branches of animal life it makes a lot of sense that they are so very important I think only sponges are older but I might be wrong
I have a new appreciation for jellyfish after this. Wow.
The voiceover is so soothing!
This is genuinely one of the most interesting videos I’ve ever watched
I stumbled upon this channel but I love it!
Great channel, I'm gonna binge all the videos
Sun and moon to close off the ending, omg so nice.
