- If you’ve ever looked at a frog’s head, you might have noticed that they don’t have external ears. So How do they hear?

I can't hear very well either when someone fills my lungs with saltwater
You can still hear, but only for a while
I was thinking this exact thing. WHERE'S THE MONEY LEBOWSKI?!?
My brainwaves also decrease in strength during this experience.
Hey guys if you like quantum mechanics and blackhole then do visit my channel once pls 🙏 🙏🙏 🙏
It is so annoyingly distracting. When it happens, I can't even tell if I can hear or not.
are we going to talk about how some guy put saline in a frog’s lungs
Yes... talking about stupid "experiments"... WAAAAY back when we were kids, we used to fill frogs asses with air by blowing them up with straws...
I know... kids can be cruel and i feel shame for what i did as a kid... But finding out how the world works is not always as clean as we would hope...
That was what I was thinking, poor frogs....
Thought the same. I'm glad scishow usually doesn't shy away from the more awful side of science.
@@rlrfproductions you know... The best part of it is to recognize that given experiment was awful. Taking the knowledge (which we could not gain otherwise), saying "don't do this again kids" and moving on.
Well as they say the other side is water tight. Even if it's salt water
Those coqui frogs are originally from Puerto Rico. That sound that Hawaiians hate is very very soothing to us.
3:57 "how your noise cancelling headphones work"
*cries in poverty
Humans have ears and can join a sing-along.
Frogs lack ears so they join a sing-a-lung.
Hello Master T., it's good to see that your pun game is still going strong. :)
Human who have hearing disorders could afford ear machines
Feel bad for poor frog who lives in their tiny World
3:11 their neural response shrank when their lungs were filled with saline solution? _you dont say._ 🙄
"filled their lungs with saline.. the neural response shrank" i have another explanation for that....
Yeah, except that's not as big a deal for a frog as you might think. Most (all?) frogs and other amphibians breathe primarily through their skin. The lungs (if present) are pretty much just a backup for when their skin dries out.
@@jeremydavis3631 they covered them in goop too so thats not helping prove your point :(
@@shanleyshoupe7873 Huh. I didn't notice that if the video mentioned it. If so, that would probably make it harder to breathe, yeah. Unless the goop readily dissolved oxygen, in which case it should be similar to water. But I don't know.
@@shanleyshoupe7873 pretty sure it said saline or the sound dampening goop, but still, some scientists are awful
It did say “or”
makes sense why i love the fireworks' soundwave, feeling the boom in my chest is the best part!
You're a frog?
Lmfao!
@@thehumanistisin9924 shhhhh -ribbit- 🐸
I most strongly disagree with that delightfulness of experiencing such infernal racket, as I feel my internal parts vibrate in a frequency near edge of bursting outwards in gory spectacle of unbearable ache.
When you're at a concert, and you feel that deep base thumping through your chest.
😍 That's my favorite feeling in the entire world. It's why I have a bass speaker. It soothes me but I swear no one else feels like that
Exactly what I was thinking.
And you think "well this sucks I can't actually hear the music"
Hey guys if you like quantum mechanics and blackhole then do visit my channel once pls 🙏y
@@Joel-tm7xq I mean, sure, but bass is all that matters sometimes. Well, to me it does
Hold on a second, yall drowned frogs to see if they could still hear?
They can breath through the skin if i recall correctly. But filling the lungs sounds painful
xWood4000, and they covered their skin with silicone grease.
Hey! If ALL frogs had POISONOUS SKIN and ooze toxins, I think this whole comment section would be different🐸💚💲💰🤑🔬⚗️💉😨
They said “or” they didn’t do both at the same time. So the frogs lived!
Covering frogs in grease and filling their lungs with water sounds like an ethics violation 😟😩🤯
A mans gotta do what a mans gotta do... progress can hurt sometimes but it is necesarry
@@proxy90909 ..That's pretty much ethics counsels in a nutshell, with added beaurocracy
Sounds like the beginning of a french recipe, actually.
Im just saying that must hav really sucked for those poor little dudes 🥺
I don’t think those frogs survived the ordeal. They breathe through both of those surfaces.
I never thought of why frogs didn't have ears, now I have. Thank you sci show.
Wait...covered them in silicone grease or filled their lungs with saline??!?!??! Do we really need to know the specifics of frog hearing that badly?????
I love how _casually_ he mentioned drowning frogs to see if they would respond less to sounds.
I took my undergrad physiology class with Dr. Narins, one of the researchers you cited! This video reminded me of the many stories he would tell the class about studying the coqui and other frogs! What a great guy.
is he connected to the “covering a frogs skin with goo and filling its lungs with goo, seeing its neural response shrink, & concluding from this that this is proof that it hears thru its lungs, rather than that the frog was just drowned in goo from the inside & out” experiment at 3:06
@@AuntBibby I bet you can find that out from the list of references.
I remember him talking about frogs with supersonic calls to shout over waterfall noises, and tree frogs using their arm bones to transmit sounds from shaken tree branches. That kind of stuff.
Nope, it's too late for this kind of weird information, i'll watch it tomorrow. Not dealing with this right now.
Did you dream about frog lungs?
@@limiv5272 maybe I did, but my brain was kind enough to not let me remember it.
Wait... "Filled their lungs with saline" those poor frogs.
"We filled their lungs with saline.."
Wtf science! 😨
Yeah that is messed up.
Yeah but it's in the name of science to help us understand the animal so we may help them one day when they need us.
I don't know much about frogs or amphibians but I'm pretty sure they need their lungs to be filled with air, not saline, in order to stay alive... Then again they never said anything about the frogs surviving the procedure...
@@glenngriffon8032 There are too many frogs.
@@twitchdoomx Okay, but are there more ethical ways to achieve the same effects?
So the lungs act like a ‘subwoofer’ ?
A subwoofer makes sound, the lungs of the frogs perceive sound.
More like passive radiator. Google it, it’s a fun sound engineering invention.
@@limiv5272 reverse subwoofer
Filling my lungs with salt water will also result in a decrease of neural activity.
You're the sanest person here!
@@sheilabilyeu5689 I wouldn't go that far LOL
This could act as a primer on hearing for people deaf from birth.
Putting fluid in frogs’ lungs is cruel. Bastards.
Hears someone whispering Breathes heavily
It’s Stefan Chiiiiiiiiiiiiiiiiin!
Hey that's really cool
Scientists: Fills frog’s lungs with saline
Me: That is cruel, I pity those frogs.
I'm so goddamn shook that frogs hear with their lungs. I read the title and instantly vomited from sheer confusion and fear. The fact that animals hear with their lungs is a huge cause of anxiety for me and I will never recover
Ok as a Puerto Rican, the coqui is our native frog and we all grow up hearing it every night. It's pretty US-centric that you guys focused on the residents of Hawaii instead of the millions of Puerto Ricans that live with it every day for generations. Hell even the Taino natives drew the coqui
Idk about frogs specifically, but in humans at least, the Eustachian tubes function mostly to drain your middle ear and keep it at the same pressure as the atmosphere. Never heard of them transmitting sound before. I guess they probably transmit some sound to your other middle ear, but I doubt it's much given how narrow they are and how round-about the path is. Even if a good amount of sound got through one tube, I expect most of it would be lost from the air via absorption by your body and reflection out your much larger nostrils. Sound diffraction, reflection back at the other ear from the environment, and bone conduction all probably play a much larger role than Eustachian tube conduction.
Cookie frogs? I've heard it all now.
So what's your job ?
I PUT GREASE ON FROGS
Hearing with your lungs is super easy, barely an inconvenience.
Anyone else old enough to remember those skits with Grover and Kermit fighting over Grover trying to sell him stuff totally useless to a frog? Including earmuffs?
Stop screaming my lungs
are hurting.
go go Sci Show
every time i learn something new about frog anatomy im left with more questions
they cant breathe with their mouths open
they dont have ribs
and now they hear with their lungs??
i love frogs so much
This explains Tympole.
Coquis!!! The frog of Puerto Rico!!
Fascinating ! Thank you.
I don't know why I thought this but this made me wonder if I were to fart loudly near a frog would it hear it, and be scared, or hear it, and go towards me.
If your fart sounded exactly like a male bullfrog, and you didn’t move at all, maybe, but not likely.
imagine covering frogs in thick grease to see how they hear things
Low-tier classes sure do have the weirdest attributes and abilities they invest stats into.
Animals are so much more skilled than humans, and in so many ways...!
I love the coquis...
I live on the island, I clicked to comment: If coqui frogs had ears, they would realize they are SO DARN LOUD. Then the video began with Coqui frogs 😑
I'm from *the* island the coquí comes from originally 🇵🇷, and I can't sleep without the sweet sound. I'm hearing them right now, like a lullaby helping me fall asleep.
Coquis are our gem and we love them 🇵🇷
Sound is so crazy cool
Frogs can hear until the police come and they turn deaf.
Frogs: I can't breathe.
Hey what amazing music did you breathe today?
I have not been in Hawaii, but I have been in Puerto Rico and heard coquíes there.
I'm remembering that there are some frogs which don't have lungs.
Filled their lungs with saline? That sounds awful.
Drinking game: take a shot every time he says tympanic membrane
At around 1:41 Stefan said that the pressure difference enabled the frogs to determine the direction from which the sound originated; Wouldn't there also be a slight difference in the phase of the sound waves which the frogs might be able to detect? I know that this is the case for us humans, so why not frogs too?
We can? By how much?
That is actually pretty cool.
Maybe the difference in the sound waves phase isn't big enough because of the small distance from one "ear" to the other.
By the way: You can tell that a sound's coming from behind you if your brain already knows that sound and it has a lower frequency than normally
0:52 you said the frogs "inner ear" I thought you said they have no ears? Which one is it
0:22 "external ears"
No opening for sound waves to pass through
I love frogs and snakes !!
Show some respect for the Coqui 🇵🇷

Please add the titles to your lists of sources! With just the DOIs I'd have to first open all of the links to find what I'm looking for
Pffff, what? You’re telling me you CAN’T? Weirdos.
"Can you hear me now? Good!"
*someone poured saline into a frog's lungs*
i never realized they never had ears
Oh, silly, of course they would have to be able to 'hear in some form. Didn't you notice the circles behind their eyes, right where there's usually eats?
Kinda feels like they tortured the frogs to figure out how they hear...
I'm sure if they had given some thought to the process, they may have used something the frogs could have 'recovered' from. Like maybe just temporarily putting some kind of 'plastic' wrap, anything that could easily and quickly be removed. How would a scientist/researcher be able to tell the difference between 'dying', or actual results, if it is killing them>?? Don't forget, SOME OF THIS STUFF ON YOU TUBE IS NOT ENTIRELY TRUE OR REAL!!!🤔🧐🤨😉
Franecki Extension
I have ears and so many problems. Teach me how to hear with my lung flaps, señor
I'd love an episode of why so many people are scared of spiders 🕷
Wouldn't filling an animal's lungs with saline drown them and them there would be no neural activity?
WHAT IF WE HEAR BY LUNGS👍
I dont understand people who dislike these videos
It's trolls who can't type.
Fark I LOVE frogs!
Do low frequency sounds not carry much energy or is it they don't deposit much energy?
me lmao
breathe through the skin, hear with the lungs, what's next?
They eat with they're tongue instead maybe?
Did this video topic come up after researching for the latest SciShow Tangents episode?
It feels like some movie like breathe through the skin, hear with the lungs 😅😅😅
Wow I had no idea Hawaii had coquis!
lungs are vital for hamon users
He forgot to mention the sacculous. BUD. WISE. ER
🐇
Bro..... 🐰🐰
Grease 'em up baby
Did that appear on their lineage or was it found in our last common ancestor?
Depends on what you think our 'lineage' is. I believe it somewhere between the Bible and evolution. It seems to me that God may have created things to be able to evolve.
*they do what now*
Filling lungs with silicone for science
All I can imagine now is someone taking a knife to their ears or filling their lungs with some kinda caulk.
Why is it that i don't feel the uncanny valley when looking at a frog when it actually doesn't have an ear???
Same with other insect and animals.
That's...weird.
And we can smell with ours.. Who knew
looking for love in all the wrong places.
He needs to do all the episodes. He's easier to folllow.
1.:32 guess this is not an ear..? -__-
They do have ears..
Suwako Moriya really enjoyed this video, but she will punish those who tormented the poor frogs with saline in their lungs.
I thought Coqui were from Puerto Rico...?
coquis are from Puerto Rico tho
Oh...
Did you Breathe that sound bro?
Can a fish 🐠 hear sound 🔊?!
3:11 They give them lung drinks?
I'm curious about the testing that involved filling a frog's lungs with saline. That seems somewhat cruel. I think they can breathe through their skin, though, but then why do they have lungs...am I mixing up frogs and toads? I hoping to be a marine biologist when I grow up, so I ask for any random animal knowledge y'all have, as well as a hopeful answer to my confusion. Feel free to go into as much nerdy detail you can, because if I don't understand something I get to do research. Also, have a nice day
They filled frog's lungs with saline water? Wtf
Loved it!! You gave me questions from answers of questions i hadn't thought of....thanks!
Do we hear through our body?
