Salamander gets arm cut of: "oh no"
Salamander 90 days later: "anyway"
Gets arm cut again
Lol
That's a long anyway
@@captainrex2448 imagine waiting that long just to get it cut off the day you get it back 💀
Why is dart’s face a meme!?
Human: “Be careful driving my new car, it costed me an arm and a leg!”
Salamander: “...So what’s your point?”
Nice one
It takes time to grow it back
You got a heart six years later wha-
@@jimmyjim5yearsago376 that's was a joke
You have a very good sense of joke....
I’m glad you clarified that was a time lapse. I thought three months was just passing by.
It’s like Kermit jumping from the roof 😂
i was ready to get the xmas decorations out :(
Her: dont worry, it will grow back.
Salamander: easy for you to say...
After the salamanders arm grows back, it uses that same arm to pull a lock of her hair out of her scalp and it tells her, "don't worry it'll grow back"...
I did this to myself but I'm still waiting for it to grow back.
almost....just wait
Lol rip
We'll is not coming back anytime bud
yeah same like its just bleeding very unhelpful video
Lol
"It has bones, nerves and muscles, and it can even wiggle, in fact it's perfect"
*CUTS IT OFF*
Classic psycopath, destroying things that he/she admires
Humans!
perfect.. too perfect.. let me fix that
It’s an animated salamander
"So anyway I started regenerating"
I really, really hope good science and research is going into this to give people who've lost limbs their limbs back.
Do you know David A. Sinclair and his works about cell resetting via 3 of the 4 Yamanaka Factors? Well, next year is targeted for the first human trial to treat glaucoma with this.
The goal isn't less than just to cure literal aging with regenerative medicine including regenerating limbs and stuff within around the next 10-15 years.
It already works very well by the way. Wish you best health and a bright future. 🤓
Based on my extensive knowledge of comic books, it will probably just turn them into big, humanoid salamanders.
@@maxburrill6192that sounds cool too, I wouldn't mind
So naive
@@maxburrill6192 By then we will also have the superhero to save us 😉
That salamander really said “Tis’ but a scratch.”
Yep
I guess you could say this research costs an arm and a leg...
you win
sTOP 😂
BROOOOOO NOOO STOOOOP 😭😂
Lol
@Sexy Uchiha ur name annoys me
The people who disliked this hate the fact that they can’t regenerate limbs
Not me but i wish we can regenerate limbs lol
True but I dislike it because they take the limbs off for no GOOD reason
Lel
Or maybe cause they hate science
@@snakesnake9882 uh...you mean the limbs of a cgi salamander?
I love these old educational videos. They seem so monotone yet very educational and entertaining
I’m starting to realize why the doctor who became the lizard in the Amazing Spider-Man was so obsessed with this stuff. It’s fascinating!
Except he became a lizard, not a salamander. Lizards can only regrow tails too.
"AHH! MY ARM!! DO YOU HAVE ANY IDEA HOW LONG IT TAKES TO REGENERATE THAT!?!?"
ha
Gravity falls reference?
Santenoturtle is that piccolo?
Santenoturtle how long does it take?
7 to 10 weeks
(cuts off the limb)
audience: HAHAHAHAHAHAHAHAHAHAHAHA!
That's some sadistic audience.
COMEDY
@@nikahathusan5373 hahaha it's just a normal reaction. We usually laugh when nervous or have a WTF shock moment, which is having a detailed animation of a scissor cutting the arm off and blood spilling hahaha
They were shocked at first (feeling bad for cutting the lil guy’s arm) but then the quick realization that the salamander isn’t real and how they reacted to it, they laughed about how they felt for a digital salamander in the moment 😂
Savage laughter
I just found an injured salamander under a plant I moved, I was sad that I possibly hurt it. I’m glad they have the ability!
I wish if all living beings could regenerate lims like this!
Oh lordy if only..
Imagine be chilling in the forest and out of nowhere someone cuts your arm just cuz grow back.

This is great news! I need to send this video to Dr. Connors right away!
Just one of the many appreciative amazingly unique things like this in nature that don't come about in life on accident and can't be totally learned without being able to see it with your own eyes.
evolution is amazing, isn't it?
@@9181shreyasbhatt *"evolution is amazing, isn't it?"*
That's one way to put it, lol.
Salamander: *looses an arm and a leg and regrows*
Edward: *that's not the law of equivalent exchange*
Lmao true
Now that I think about it why didn't Ed just transmute himself a new arm and a leg? The show, atleast brotherhood showed transmutation of human bodies was possible. Getting the soul was the problem.
@@ShamanMcLamie yes he did, Alphonse transmutate him self to get back ed arm.
And why ed didn't transmutate new arm? It because reaction of soul, Alphonse several time get rejected in armor and pulled to his body, so if they attached body that not even their the reaction happen, this probably because their body still exist and not destroyed
500
@@ShamanMcLamie Doesn't it need to be HIS arm and leg to work? Otherwise his body will just reject it? If I recall correctly, at the end of the series he gets his arm and leg back, but it's his original childhood limbs that were hanging out with Al's body behind the door, so they are severely malnourished and skinny.
Just imagine if we could find a way to harness that ability. Amputees, would be able to regrow lost limbs, the paralyzed could potentially walk again. No limit on human tooth loss, in short heavily damaged teeth could simply be taken out and regrown. muscular dystrophy could be a thing of the past. The list goes on.
that would be absolutely amazing! I thought the same
lol look at planaria worms. They are even more amazing in terms of regeneration
But then they would turn into vicious humanoid lizards, and Spider-Man would have to stop them.
This happened on spider man it did not end well😕
dude do you really want Lizards in real life (the guy from spider-man
We need that deadpool regeneration research ASAP!
UHHH
Someday in the future, humans have the ability to regrow limbs thanks to much, much advanced scientific research.
The lizards will have to put a stop to this.

She has arms for limbs
BUT I GOT WATERMELON FOR LIMBS
This is why I love salamanders, more particularly Axolotls. They're my favourite animal, not just because they're cool, but from a science standpoint too. Axolotls were named "The Masters of Regeneration" for a reason, and studying them provides research that could one day prove to be invaluable.
Man, I edited corrected the position of the quotation mark and lost the heart. Feels bad man.
@@thecloaker7962 :(
Aww bummer
I have an axolotl, and no joke, his leg fell off and now he has 5 legs-
If an axolotl's leg falls off/ gets hurt they grow an extra leg.
Be careful with yours or you shall end up with a centipede
fun fact: Axolotls were praised by the Aztecs. you can see them in their temples
This is incredible.
0:27 everyone starts laughing when its leg gets caught off.
Yep
and you can hear some people concerned
0:27 y tf they laughing???
because they thought it was real and laughed at themselves when they realized the truth
Cause it’s caught them off guard
@@JhoF79 no, it's because the woman was saying "they are amazing limbs and useful, now let's cut it off"
@@JhoF79 True lol
Because it was unexpected and not cute-ish but a tiny bit pitiful with cuteness but not cute at all and really unexpected
It has nerves, muscle, and can even wiggle.
idk why but it makes me happy seeing a virtual newt wiggle its little arm.
The True Godzilla 🤣
Lol
“Wiggle it’s little arm”
Now we're cut it off💀
choppity chop chop

This is one of the most amazing things in all of creation imo
Well explained!
The Salamander's eyes at the end:
"Please don't do that again."

Cool
This “how to” looks fun! I’ll try it with brother later today.
"Now we're going to cut it off..."
Audible shock in the audience.
Narrator: Proceeds talking as if this were to be considered normal.
only if humans can do that
we can. Not with limbs but humans can regenerate small parts of their bodies, like a piece of a finger, or a nail. We don't regenerate bigger parts because it takes too much energy and requires special types of cells to remember the complex structure of the limb. Humans are too complex (not only humans, pretty much any large animal) so the amount of energy and the time that it would be needed wouldnt be worth it.
Matheus D. Rodrigues :D
Matheus D. Rodrigues br? Tu e mto bom no inglês slk
Matheus D. Rodrigues can't humans regrow their livers if part is removed for a transplant for example?
Ratchet4647 yes they can
if you get a liver transplantation your donor just gives you like a little piece of his liver and then if your body accepts it it will grow to an almost normal sized liver over time

Can people really not see the difference between a 3d model and the real thing do they have to put a disclaimer no animals were harmed in the making of this video
Jack Turner no they were also watching the animation.
how to study it thought without harming them. Cuting the limbs is one way to prove the theory
people are just that stupid
John Boe Indeed.
Maybe it's for young kids watching the video? Better to have it then not have it I guess
0:34 Looks like fresh cucumber.
Anyone else remembered Dr Curt Connors after watching this??
Hell yes lol.

I thought of and wrote most of these ideas years ago!
One of the many reasons why lizards are cool. Nice and informative video, btw.
To everyone talking about mixing this with humans, remember spiderman? Lel

well i don't remember spider man his arm cutting off and growing back again :D

I'm sure many already know this, but a human liver can regenerate too. Cut off half of it, and the missing part grows back.

yes.. and that's why you can't kill lizards, they just multiply!
Yes Bamitse, yes it did grow to a new lizard.
Nope,it does not grow to new lizard because there is not enough genetic information in that part.
