Troglofauna: Animals of the Caves
HTML-код

- A video about some of the more obscure animals that science knows of, troglofauna/troglobites. Yes I know that the ocean abyss also counts as an environment with no sunlight, but hey maybe that will get its own video as well.

Random fact about the Olm: They possibly have the longest natural lifespan of any amphibian, >100 years, surpassing humans in their longevity
Yep. That thing's a dragon
isn't that because they basically don't move for years on end?
I'm your 200th liker here & bye.
Dragons please
Humans can live over 100 years in the proper conditions & diet. A friend of the family died at 105 years old. Never ate junk food & he ate lots of seafood.
5:18 Actually cave elephants do exist. A population of elephants in Kenya are known to go miles deep in the caves of mount Elgon. They do this in order to find salt licks, which are essential to their survival.
Don't count. They go to cave but they don't live in cave.
They crave that mineral
@@JeRefuseDeBienPrononcerBaleine They'd be a "Cave stranger" right?
@@Nanamowa Probably.
I've heard about this, they do it specially when they are pregnant. The minerals help with the nutrition and the development of the fetus. So many generations of elephants have licked that cave that it has expanded, as if it had been mined a little bit
- " Oh hey pooh, how are you "
+ " They took my fucking eyes "
I almost snorted after reading that lol
Can't wait for the caves and cliffs update.
LMAO

Makes me realize we could've had a way bigger update to cave creatures.
Other than just axolotls and glow squids. (Though those are pretty good too.)
Like if they managed to fit hundreds (or was it thousands?) of unique tropical fish in a single update, it can't be too hard to add like 3 or more unique cave fish that will only spawn in absolute darkness right?
@@jonatanluna1061 Cuz those millions of tropical fish variants are literally just texture overlay combinations, no unique AI, mechanics-- nothing, just a retexture.
Unless you're asking for an exact *same* carbon copy of the *same* exact mob with texture being the *ONLY* difference to be in the caves; that comparison is simply and outright wrong, even Glow Squids are still unique from regular Squids.
Besides; mobs are like 20% of the update anyway buuut I do wish they do an update focusing entirely on mobs.
@@user-tzzglsstle585e38
Yes I'm saying that would be the easiest way to add just a little more unique life to the cave.
Tropical fish but they spawn in the dark and have a different texture.
I don't know exactly which part you're saying is wrong.
Basically it'd be the same update but instead of just glow squids in every underground pool there'd also be some cave fish swimming around.
You also may see axolotls swimming around killing cave fish which would make them easier to spot in larger underground pools since they'll be moving around a lot.
I really loved the waterfall climbing cave fish, the way it climbed was uncanny. Really good video!
yes
If you wanna watch other fish climb waterfalls watch videos of lamprey climbing waterfalls. That's some weird shit
It reminds me of a buff colorless epaulette shark
Fun fact, many house pests evolved to be subterranean creatures first. House spiders, house centipedes, cellar spiders, etc. Maybe that’s why we find them so creepy compared to animals we find in our backyards
I don't like how all of them are called by a word connected directly to a house.
@@dodgemaster6963 A house is just a replica of a cave built by cave apes.
@@dodgemaster6963 scariest of all creatures, the housewife
Yup! Many creepy crawlies that invade our homes initially invaded our caves! This is because they benefit from living around us. Take spiders for example: They don't seek out humans as a food source, but they do live around us to benefit from food sources that we might attract, like flies, mosquitos, cockroaches etc. We're longtime housemates!
We wuz cavemen
My family is from Slovenia and I've seen the Olm in person! They're so fascinating, in Slovenia they call them človeška ribica which means human fish
Jes sm tud iz slovenije in ribica mi je zelo luškana
Lol, that's so cool.
In Croatia we call it čovječja ribica.
@@dinofanaticgojifan5760 the same
@@peabrain6872 it isnt
I love how the raccoon just tosses the fish on the ground. Hilarious animation.
Or the bear hoping away... quality stuff
The best one that you didn’t mention were the huge cave fish discovered in an Indian cave a few months back. Probably some of the biggest cave animals. It’s really cool. The golden cave catfish is also interesting.
The new species from India is very interesting, I'd never heard of them before
whats the species name?
@@ihateyoube Yes please, I want to know too
@@mae8646 Look up "World’s largest cave fish discovered in India" on National Geographic
He probably didn't mention it because it hadn't been discovered yet lol
It's fun that most of these adaptions are similar to what you find from living at the bottom of the ocean.
slovene person here! the belief that the olms were baby dragons was largely influenced by the huge dragon culture in Slovenia at the time, like dragons were (and still are) quite a big thing there. Also when olms first started like washing up from caves in medieval Slovenia it would be after storms or earthquakes, strengthening the belief that they were baby dragons!!
I saw the olms in a video years ago and I thought they look like dragons.
i was intrigued by the salamander on the thumbnail. the alm (or olm) looks very similar to the axolotl ( the tadpole of the tiger salamander). with the same pink gills being just a bit shorter than the regular axolotl and surprisingly long. and not to mention that snout. (edit: sorry very CLOSELY related to the tiger salamander, not the tadpole.
i clicked on the video thinking “haha funny long axolotl” but i find this entertaining and educational
Axolotl is related to tiger salamander, bur its a different species.
Fun fact. In slovene (the language of the cuntry it was discovered) if directly talslated it woud be caled "human fishie". Because of its similar skin tho that of a human (in slovene its caled "človeška ribica" if your wondering).
The axolotl has a big snoot
reject axolotl, become *_o l m ._*
The only way I could tell that the picture of the cave fish was in water was because of the fish swimming. That is _eerily_ clear water.
I agree, my brain was confused for a little while
Water that's seeped through multiple layers of rock is bound to be very, very pure, assuming the rock isn't of a kind that dissolves easily like salt.
It would cool if you could do an episode of the cave that was completely sealed off and they still found tons of life in it.
I need to know about that
@@juancho650 look up sealed romanian cave.
Very cool and creepy
@@danfurtado9158 i did a quick research actually sounds creepy realizing they were that long buried alive, and still survive until today, I always wondered if that was even posible, there must be more of these kind of caves somewhere
@@juancho650 Look up ecospheres, or closed terrariums. Lots of people take sealed containers with hunks of vegetation, dirt, rocks, and water, and let it sit in a window or something. Eventually, life tends to spring up, and thrive anywhere from weeks to years. Something like a cave lasting many years isnt far fetched, the its more unlikely such a cave would form without killing the life in the first place, than the life not being able to live in it.
@@pauldeddens5349 A terrarium is very different: it has light.
Imagine evolving for a billion years to just be born without eyes and sip sewage water, yum
@@Ligerbee well *techincally*
"I'm in a bad place"
"Mentally?"
"No, Gary, Indiana"
I love cave creatures, especially the idea of like, a completely unique animal that's not just exclusive to a continent or region but just a cave system.
Your humor with this is amazing . The Gary, IN comment made me chuckle lmao.
Welcome to Gary! We got kickass barbecue, many amazing Jerk Chicken joints, Chicago gangs running rampant in the streets, and great beachfront property in Miller!
Stygofauna, a reference to the river styx, is the most badass word I've learned this decade.
Some of these cave fauna kinda remind me some of Junji Ito's horror work such as how in one of them a bunch of people who were thought to be missing were discovered to be alive in a giant serpent thing and are found to be alive but living like parasites in the deep darkness of the abyss while inside the serpent, really chilling stuff
Wow, the cave ecosystems are kinda batshit, literally

"Hypothetical cave elephant"
There are elephants that go quite deep into caves to mine mineral deposits. Their mining is on such a scale that they may damage the structural integrity of caves and cause cave ins.
And they have been doing for probably thousands of years
Damn environmentally damaging elaphants. We should go shoot them all. They only think of themselves.
@@viktordickinson7844 time to hunt some corporations
@@Scarabola i said elaphants
Your audio is plenty good enough. It is clear, and your speech is succinct. You are an excellent presenter.
cave endemics are so cool. i wanna see cave bugs but i’m scared of caves
Extreme life is really interesting, a glimpse at what alien life might be(kind of)
The Alm and Waterfall Fish seem like really good examples. Not many other things on earth have the extremes they do. Most fish struggle to do anything handlike with their fins due to competition. The best we have are frogfish, handfish, blennys, and mudskippers. And the Alm is just some really strange salamander nonsense.
Good video, deserves more views. I feel there aren't enough videos about cave ecosystems on youtube so I'm glad I watchef this.
The "sigh of uncreativity" had me laughing
Same. 🤣
Same x2!
Am Slovenian, can confirm. The olm is our national animal.
Olms totally look like one of the creations of the Qu from All Tomorrows..
I like the graphics, and the presenter's real live and engaging voice.
Really informational, subscribed!
Imagine if the waterfall climbing initiates Evolution of Vertebrates/Tetrapodes 2: Cave Bugaloo! 🤔
This looks like a Japanese Dragon!
When I was a little kid, I did a project on the olm. Built one out of clay and everything. One of my favorite underground animals
Fun fact about cave fish. While it has been suggested that they have lost their eyes to become more energetically efficient (they don't have to spend energy growing and maintaining eyes), its actually due to the how genes in the face of the fish work. Basically the fish are able to have bigger mouths due to lacking eyes, and a bigger mouth is gonna be much more useful than eyes in complete darkness. For one thing to can eat bigger prey, which in such a resource scarce environment, is hugely beneficial
Ok so I watched one of your vids this morning and I'm watching this one at night - you gained over 2k subs in under a day. Bro wtf that's mad, good job my guy
Another fun fact about olms is that here in slovenia we also have olms subspecie called the black olm, basically looks the same, except that it is black in colour. They live specifically in southeast slovenia (while normal olms live thruout most of the lower half of slovenia, where they are mostly concetrated, all the way down to montenegro)
I love this! You deserve much more subs!
the style of borders of text pages around the pictures looks really cool !
You're a stellar narrator!
Thank you for your video! There was surprisingly little I could find about caves on youtube. Though perhaps I'm just bad at searching.
Cave life is so fascinating.
I don't know how i unsubscribed this amazing channel, maybe i just forgot.
Excellent video my guy
Very Well Done video!
Keep 'em coming! 👍
fun fact: olms also come in black. they get discovered every so often in random caves in slovenia
Its 8.30 pm, I got my final exam tomorrow and havent studied one bit yet. Am I really gonna binge watch this guys' zoology videos now?
Yes, yes I am.
Very interesting and entertaining. Thank you!
Great video, very interesting topic. Makes you wonder how deep down life can survive
In Slovenija we call the olm human fish. There have also found 12 examples of the animal that were black (aka with pigment), and had eyes that were apparently functional.
Whoever named that crab was obsessed with alien
love love love your videos!
This channel is a blast.
I love how the water is so clean that the fish look like they are flying
When wayz tells us to drive through Gary we don’t listen
Now i know why the Troglodons are called that and why theyre blind and pale!
Very informative, felt like I was watching a documentary❤
Amazing writing 👌 part 2 maybe?
"OK I'm born, what do we do now?"
"We sit on rock."
"And then?"
"We open mouth."
"Yeah, aaand?"
"Eat."
"Uhuh.."
"That is all."
"Oh no."

First time seeing one of your videos. Definitely be back for more! Liked and subbed.
You earned my subscription
great video
Yeah now the funny thing is right before I saw this video was a thing my teacher had an assignment on troglobites
Also another fact about the axolotle looking thingies which I saw people calling them the Texas blind salamande, they do have eyes but their eyes are very small and deep under their skin to a point where they can’t use them.
Texas Blind Salamander and the Olm are 2 completely different species, though they look similar.
Salamanders seem to be the only tetrapods that can exist full-time in caves for enough generations to undergo changes like that.
Finally i know what it means when charlie calls ppl troglobites
I believe he uses troglodyte
@@vkai782 oh, youre right. Troglodyte is cavemen while troglobites are animals.
@@vkai782 can negroid people be troglodytes????
Great video
The blind, albino humanoids from the horror film The Descent also come to mind
litteraly just learned about the waterfall climbing cave fish last night while researching for a Salween river biotope aquarium
0:09 as a hoosier, I can confirm, Gary is terrifying
For some reason the phrase “flood trash” makes me chuckle
wow thank for the knowledge
When we think of how many animals that got the name cave attached to them isnt it kind of weird that Bats aren’t named cavebirds?
I just help but wonder if something would happen if you took them out of the cave and placed them somewhere else, what effects could that have?
And to think there are most assuredly 10s of thousands of undiscovered nigh sealed off caves with unique ecosystems and species yet to be discovered. These are already interesting enough. Hope they discover new caves with interesting life soon in my lifespan.
I really love cave ambients. They're like the coolest shit because in the deepest depths of earth THERE'S STILL THRIVING LIFE. Almost unrelated but Brazil has a species of catfish living in underwater water reserves. People usually find them when digging up wells, granting it the name of well catfish (bagre de poço) and they're completely pink and blind as one would expect.
Unfortunately it's also in decline since they're pretty rare and fragile to pollution, specially coming from big crops like soy and corn, which Brazil is pretty known for, and the poison they use to y'know, kill bugs and weeds penetrates the soil and end up in those groundwater reserves.
weirdly intriguing video
that scene with the bats leaving the cave looked exactly like the cave guarded by the rabbit in monty python and the holy grail...
Thank you
Great vid i hope those waterfall fish get studied more
nice video
I've been to the carlsbad caverns, they're really cool
❓ Movile cave in Slovenia is 5.5M years sealed, has chemosynthetic base ecosystem, completely sealed from the surface (even from water), yet still has vertebrates (eyeless cave loach (Proteus anguinus)). Truly a remarkable system.
Good video
the "uncreative sigh" got me
I've always been curious what a cave fish or something tastes like.
Propably like what they eat... shit
Oh my good dude user Hot Soup, do cows taste like grass? I’m no food chemist like you user Hot Soup but it all comes from the sun right? It can’t be that bad.
@@danielkraybill3356 enjoy your shit tasting fish man whatever you want
@@LesserOfTwoWeevils I bet it’s delicious fried up with a little butter. I bet they’re just keeping it from us so they don’t get over fished. I bet you know this and you’re trying to throw me off the trail.
maybe very bland, without much variety of nutrients in it
I wish I could live in cave as well :< the animals seem pretty safe down there
I was surprised when I saw a picture of myself in the video and a description of how I like to live in caves
What's the music used?
Man the creature in the thumbnail really do be an axolongle
Walking in a cave in the dark alone was one of the most peaceful and incredible experies of my life ngl
*trips*
how does their circadian rhythm work, when they can't sense day or night? do cave animals sleep? how can they tell time?
WOAH SO THIS IS WERE THE MINECRAFT CAVE SOUNDS COME FROM :000
You forgot about chemosynthesizing bacteria. Which are autotrophs that rely on hydrogen sulfide. You also forgot about chrmollithoautotrophic bacteria which use various minerals to generate energy. These can also form the basis of a food chain.
True and it's those critters that make life in nigh completely sealed off cave systems possible.
🤓
Great video! :)
damn i never heard of these SCPs, thanks Volgun!
As a Hoosier I can agree that I would not want to be in Gary, Indiana.
I'm from Chicago and I love Gary my Pops stay in Miller Beach
Ah yes, the Olm
