Keystone Species of the Deep Sea
Vložit

- The deep sea relies on keystone species to maintain balance. Through predation, competition and symbiosis, changes in the population of one species affects the population of another. But at the heart of these diverse and vibrant deep sea communities are the keystone species, whose presence keeps the balance in the ecosystem by determining the numbers of other species. Without keystone species, ecosystems would look very different, and if they disappeared, the oceans would be more vulnerable to environmental change and would experience a rapid decline in biodiversity. The three different kinds of keystone species, the predators, ecosystem engineers, and mutualists, have very different roles to play in order to maintain their ecosystems. Let’s take a closer look at these, and examine the keystones of the deep sea.

I could listen to this narrator read the dictionary. Such a soothing voice.
Straight up
In one of his other videos you will see him, and become amazed of how young he is. A true talent he is. 🙋🏻♂️
A worthy successor to David Attenborough
@@Parken26 exactly 🎉
@@Parken26 talking about the tide pool video? I know it blew me away as well. I hope he realizes the talent he has as he has an incredibly bright future ahead of him if he continues to pursue his passion. And we get to benefit from this young man's incredible talent. How lucky are we to enjoy content like this for free. I wish he gets to achieve his wildest dreams as he definitely deserves it.
Your content is on par with nature documentaries it’s amazing
Better than, in my opinion.
It is self evident that he has surpassed the likes of NATGEO among others
Argue with your shadow
I keep saying that... they're so damn crisp
I'd say above par
This is a documentary
I'm always excited when I see a new upload on this channel.
Yay! Thanks Emily :)
When I was a kid I wanted to be a marine biologist... My mother never let me so I ended up studying something else... But never lost my love for marine biology... Your videos are my everything!
Sad that she was what shut you down :(
Yo dude it's never too late! They got people in there 70s, 80s even who graduated with a degree in something. who says you can't now?
It's your life; live it.
@@elijazfrazelsassafraz3100 yeahhh... Please never let anyone tell you what to do! 😔
@@HlootooThunderhammer I am actually planning to start studying marine biology once I finish paying the house, thank you for your encouragement 🥺💕
It blows me away how young and professional this man is as well. I hope he realizes the talent he has as he has an incredibly bright future ahead of him if he continues to pursue his passion. And we get to benefit from this young man's incredible talent. How lucky are we to enjoy content like this for free. I wish he gets to achieve his wildest dreams as he definitely deserves it.
dude's gonna be the next Attenborough
Now when you look up on the surface and take into account these keystone species and apply them to where they are supposed to be on land you see how much we fucked up by being humans. Wolves, big cats, bears etc. It's difficult to keep the balance and we barely try.
And yet, from a cosmic perspective, humans have followed their natural path. Creating and building and inventing. Tons of species can "ruin" things for everyone else.
@@DapperDanLovesYou Sure but the root of all this "ruin" from other species is because of us. Relocating bunnies to Australia or carp to the US and many many other examples. Those are not natural migrations. Not to mention all the exterminations. When it comes to ruin we excel at it.
@@anjairis who cares if these migrations are natural? Saber tooth cats made terror birds go extinct when they migrated from an ice age to south America.
If one species has the luck of dominating a new area and manages to not get extinct then it's approved by nature.
Lemmings in some areas have a cycle of 4 years where they procreate, eat all the moss and plants, die horribly by hunger until the population is small enough to let the plants regrow just to start the cycle anew. It's a cycle of endless suffering by starvation, but natural... Not really better for the animals
@@anjairis In what way is it not natural? Are we not creatures born of this planet? Did we not evolve from it? Do we not create things from the materials it provides? Hence my mentioning of "cosmic perspective."
Why should we so carefully force species to slowly die in a world that wants them dead? Isn't that just as "unnatural" as the things that lead to their demise in the first place?
@@DundG We make way more species extinct a whole lot faster than the saber-tooth made terror birds extinct. That one would be considered a natural migration so comparing that to us is silly.
Here's a question to consider about lemmings: Is there a missing keystone species to keep the lemming population in check? Did humans have a hand in these keystone species decline and is that why they do what they do now? Less big predator birds like owls, eagles and hawks. Less foxes and lynxes. Less badgers, wolverines, ferrets and the like. All because of humans and the ignorance of the balance of nature.
Pick another species that seemingly run rampant, what is their natural predator? Are they missing from the equation? I wonder why.
Loving this channel cause I wanna be a marine biologist
Do that life you're best life and what ever makes you happy
Me too!
Same, over the last few summers I’ve even been spending a lot of time seining just to see what’s around me, I was shocked to pull up a juvenile monkfish this year, thanks to that I learned that they go through a similar transformation flatfish such as flounder go through where while they’re young they look relatively normal (well in the monkfish’s case as normal as you can look with a lure on your head) and then as they mature they change to the shape that you associate with them
I'll become the industrial fisherman or off shore oil driller,
Lets fight!
same fam!
Love your channel, education of marine systems will hopefully make people respect it more and understand how fragile it is
Thank you so much, I really hope so too :)
fragile, yet it has existed for hundreds of millions of years
I just started playing subnautica and my knowledge of marine biology from channels like yours is coming in quite handy. Thanks for giving me a deeper appreciation of the ocean and things that emulate it. 😁
Best of luck dealing with those reapers!!! I’m so glad you enjoy my videos, stay curious, and enjoy subnautica :)
@@NaturalWorldFacts would reapers be considered a keystone species? Hope not because I killed them all with my knife lol
Deep, mesmerizing and breathtaking.
Thank you for these wise words, Potato Man
You have quickly became the best marine biology related channel on youtube. Congrats my friend
aw thank you so much!!!
the amount of happy that i receive when i get a notification from you could fuel me for 3 lifetimes
Aw, thanks Kim 😁
Your channel is really special when it comes to education in CZcams
Deep sea is not portrayed much in media and you bring us quality content about it constantly
Thank you a lot for all your videos
Have a wonderful day!
Whenever i have sleeping problem, i watch these videos, the voice is like a sleeping pill .. very calming and soothing
These videos got me crying, I want to protect these perfect species with all my heart and soul
My favorite narrator. It’s always so soothing to watch these videos. Thank you for lowering the volume of the music 💜 I wonder what a David Attenborough collab would sound like? 🤔
The most fascinating and informative channel on CZcams, I'm in awe of every species that goes into making the balance of the sea thrive and survive 🤗💞🤗
HE'S BACK!!!
These videos are phenomenal.
for me the thing that attracts me to a channel like this is how the narrators voice sounds..clear calm and precise soothing..enjoyable to listen to..
I love falling asleep to these videos they’re so calming
Cold by Jorge Mendez. I couldn't help but to recognize the tune in the beginning of the video. I love that song.
Such an incredible work, as always. I'm looking forward to more content from you.
A beautiful track! Jorge is a brilliant composer, and I’m so glad you enjoyed the video
You guys uploading always just makes my day dude.
Truly a treasure of a CZcams channel to stumble across
One f the bet documentaries, clearly stating the vital relationship that exists in our seas and oceans! Bravo~!!
It is a joy to congratulate you in ADVANCE on getting 1,000,000+ subscribers
For the consistently excellent mind expanding content
Much success to you ❤️💯
This is such a great video. I'm learning a lot from this, hopefully others too.
His videos fit any situation I could watch these before bed, on the toilet, at a funeral, it doesn’t matter
Oooohh, keep doing deep ocean stuff! I could watch these all day long.
you’ve done it again, leo. another masterpiece!
Amazing information. Your videos remind me of what National Geographic used to be way back in the early 2000's.
The Whale Pump. You learn something new every day. Such great film making.
What's incredible is while this channel constantly reference topics that he's covered before, such as Whale Fall ecosystems (a fantastic video for anyone who hasn't seen ) he doesn't tell you to go check that video out like other channels do. It feels natural, and makes me want to recommend these videos to literally anyone
You're videos are so relaxing yet captivating. Keeping doing what you are doing 👍🏾
I spent three days watching the videos on this channel, and I am just blown away. They’re all _excellent._ Genuinely better, and so much more beautiful than anything I’ve seen on TV. The editing, the educational explanations, the narration…it’s all just spectacular.
The only thing I can possibly critique is the name of the channel. It makes it sound very…click bait-y. It’s quite generic and forgettable for such an exceptional series of documentaries.
But honestly it could be called “fishy smart time lulz” and I’d still watch and subscribe. 11/10
Thank you so much for the kind words, and the feedback!!
I have mixed opinions about the name. On the one hand, I agree, it sounds generic and I wish it was different. But on the other, it’s been that way for 11 years, since I was 9, and has become such a big part of my channel’s identity and my life that changing it would feel strange by this point. I wish I’d thought of something better all those years ago.
P.s. the first bit of your comment put a great big smile on my face!! Thank you so very much. It honestly means the world.
@@NaturalWorldFacts Since you were 9 years old? Does that mean you’re only 20 years old? Holy jesus sakes alive 😦
Have you considered dropping the “Facts” and just going with Natural World? You could keep the original name, but it would sound more elegant.
Your voice... for months I've been following your video posts and to be quite Frank.... you soothe my soul.
Thank you so much!! That made me smile ☺️
I've watched his videos every time i eat alone, his voice is soothing, if he has a book or an audiobook, I'd buy it fr
Your commentary can make me watch a video of two senile old men fighting each other and make me feel like it's a professional documentary
Have to agree with all of the other comments. Binge watched all videos in a couple of days - it’s extremely difficult to not sound repetitive and/or boring in narrations. You are doing a great job!
I almost fall asleep with the narration. So soothing.
This is very well produced, you have a great voice and it's well captured and processed! one suggestion I'd have: the reverb tail on your vocal processing is a bit long, when you pronounce an "s" sound it's most prominent and makes it feel like you're in a cave. The reverb is a nice touch, helps with the solemn tone, I'd just shorten up that tail a bit. maybe a couple hundred milliseconds instead of the ~1-2 seconds you have now. Also, if you have a compressor downstream from the reverb I'd move it upstream, that might be what's bugging me.
Unintentional ASMR-calibre narration and some beautiful, some bizarre creatures down there
This is the best video that I've watched on a long time! So informative and fascinating.
Another fine video, Leo. I've learned more from these than you realize. Thanks again.
I’m so so glad, thank you so much for watching
It’s truly incredible when one juxtaposes the fragility and resilience of life. Keep of the awesome work!
Personally the only thing that could make these videos better would be citing sources in the description, otherwise i love these gorgeous videos and their mesmerizing narrator's voice
The quality of this content is so incredible, that is surprising it isn't from a paid service
You give me hope that I too can achieve my dreams if I pursue my passion. You are truly blessed with an incredible ability to eloquently describe a topic without going over the heads of casual enthusiasts while simultaneously holding the interest of those whom are more knowledgeable and familiar with the subject without boring either demographic.
Please never give up pursuing your passion. I happen to have always held an unquenchable desire to learn all there is regarding astronomy and physics, yet I was unable to go to college and pursue it professionally. You give me hope I can relight that spark and continue to indulge in my true interests regardless of my daytime profession. You have my utmost respect and admiration and i sincerely thank you for providing us with this most incredibly superb content, completely free. As soon as I have the means I would love to support you financially if you happen to have patreon etc.
Best of luck to you young man, there is greatness in store for you in the future, and thank you.
I love the way you handle subjects like climate change and human impact on the natural world.
many other naturalists really like to rub your nose in it, showing shocking images of devastated environments and creatures suffering and dying.
Their message seems to be that the earth and natutal world is doomed and it's our fault for being born. This may sadly be quite accurate, but the manner in which it is presented makes it hard to swallow.
So many nature documentaries are hour long sermons preaching a doctrine similar to original sin which seems intent on making people feel guilty and hopeless.
You state facts and never gloss over the impact human activity has on the natural world, but your approach is different. You show us the beauty snd diversity of the natutal world. You share your wonder and delight.
You also explain threats which the natural world faces (almost exclusively as a result of human activity).
By doing this, you make me care and you make me want to make more of a difference.
I feel that for the most part, it is not malice and greed, but ignorance and apathy which have gotten us where we are today.
If I get another teaching job, I'll take as many opportunities as possible to show your videos in class - you are a true Earth Knight.
Simultaneously learning and calming. Glad you make this content. Always makes my day to watch. I’m very thankful to have found your channel.
This channel deserves more views, a lot, cmon yt
Suddenly i see and video and opened it....Undoubtly this is the bestest channel .
cant wait to watch
Hope you enjoy :)
Love every video from this channel its helping me rediscover my love for education after feeling like school was just a chore. Love learning shit 👍keep doing what youre doing man
Wow what a delicate balance
Keystone species is now etched into my brain
This was so interesting
7:48 That was one energetic clam (fleeing from the sea star).
Relaxing and educational. The narrating voice reminds me of the creepypasta narrators I used to listen to back in the day.
i always look forward to ur vids
I really appreciate that! I think one of the biggest barriers to education is money, and it really shouldn’t be. Especially with regards to vital research, which is very important to understand as it relates so much to the everyday functioning of our planet!
This is one of my favorite channels! Thanks for sharing your lovely videos with us! ❤️
It's insane how high quality your videos are! I am transfixed to the screen every time! So well edited! So well researched! And your voice is lovely as well! Beautiful work!
Hands down my favorite undersea channel of all time!! Thank you for this much needed content. Much 💗
I love the longer videos! This channel is really great :)
Hard to fall asleep with so much music. You have a good voice, less music in my opinion. Great video
I enjoyed that. Amazing narration, interesting background music, fascinating subject! Thank you all
Love these videos man, your narration really make it an enjoyable watch experience
This channel had a massive rise in subs! And that’s great! Good to know you’re channel is getting exposure
Truly excellent! Wonderful script and narration. Please keep these coming!
I learn more with every video you post! And the vocabulary is expanding my brain... thank you 🙏
Your videos are everything I need right now. Done so beautifully.
So happy to see a new video from you I'm off work sick and this has cheered me up so much
I’m so glad you enjoyed, hope you get well soon!!
Another stellar episode, you've really come into your own. And at that age, keep up the fine work!
May you please thicken your thinnest text when displaying facts on screen? Very hard to see on lower quality streeming unfortunately. Adding depth and what oceans hold a species on topic would be very informative. I'm loving the content!
Very Very good audio mix. Reverb is spot on for your voice.
This is the best video I have watched over the years. Thank you so much for your wonderful work 🙏🏻
YOU'RE VIDEOS ARE SO DOPE DUDE! Every time....top shelf.
Absolutely love watching these videos. So very well done and very informative!
