Seen up close, the anatomy of a mosquito bite is terrifying. The most dangerous animal in the world uses six needle-like mouthparts to saw into our skin, tap a blood vessel and sometimes leave a dangerous parting gift.

DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. Explore big scientific mysteries by going incredibly small.
Scientists have discovered that the mosquito’s mouth, called a proboscis isn’t just one tiny spear. It’s a sophisticated system of thin needles, each of which pierces the skin, finds blood vessels and makes it easy for mosquitoes to suck blood out of them.
Male mosquitoes don’t bite us, but when a female mosquito pierces the skin, a flexible lip-like sheath called the labium scrolls up and stays outside as she pushes in six needle-like parts that scientists refer to as stylets.
Two of these needles, called maxillae, have tiny teeth. The mosquito uses them to saw through the skin. They’re so sharp you can barely feel the mosquito biting you.
“They’re like drill bits,” said University of California, Davis, biochemist Walter Leal.
Another set of needles, the mandibles, hold tissues apart while the mosquito works.
Then the sharp-tipped labrum needle probes under the skin, piercing a vessel and sucking blood from it.
The sixth needle - called the hypopharynx - drools saliva into us, and delivers chemicals that keep our blood flowing. Mosquito saliva also makes our blood vessels dilate, blocks our immune response and lubricates the proboscis. It causes us to develop itchy welts, and serves as a conduit for dangerous viruses and parasites.

---+ What is the deadliest animal in the world?
Mosquitoes are the deadliest animals in the world to us humans. The diseases they transmit kill hundreds of thousands of people each year.
---+ How many people get malaria each year?
In 2015, malaria, the deadliest mosquito-borne disease, killed roughly 635,000 people, mostly children under the age of five and pregnant women in sub-Saharan Africa.
---+ What diseases do mosquitoes transmit?
Malaria, dengue, yellow fever, West Nile and Zika are some of the diseases that mosquitoes transmit.
Dengue fever, transmitted Aedes aegypti mosquitoes, is estimated to make almost 400 million people sick with jabbing joint pain each year.
Scientists also believe that Aedes aegypti mosquitoes are the main culprit for more than 350 confirmed cases of congenital malformations associated with the Zika virus in the northeastern Brazilian state of Pernambuco. Since last October, an unusually high number of babies have been born there with small heads and a host of health problems like convulsions, suspected of being caused by a Zika virus infection early in their mother’s pregnancy.
---+ What diseases can I get from mosquitoes in the United States?
West Nile virus is the most important of several mosquito-transmitted viruses now native to the U.S., according to the Centers for Disease Control.

You mean, we take ours back.

What's yours is mine comrade
Haha
Yes, that was a rather nonsensical sentence. Naturally a biologist or an epidemiologists might test the blood - but what they show is a mosquito getting slapped.
@@badasstrapbass2313 communism is about taking back what's yours
I hate that mosquitoes sounds 😡

sometimes more disturbing than their bites
😅

RICKY SEKHON same
I too
I love how universally hated these tiny creatures are
Seriously. How in the world did you record under the skin to capture that incredible footage of the mosquito’s needle probing around and sucking the blood. That footage is absolutely amazing.
I saw in another comment, they use mouse tissue to record the other side
IKR, so good
Well, in the early seventies cameras were already capable of filming the fertilization exact moment. I remember seeing this in a cover of a _Paris Match_ Magazine.
I thought it was from one of the parasitic "gifts" left in a victim by a mosquito.... parasite just happened to have a GoPro...
@@ChristmasEve777 Those despicable hitchhikers seriously have no manners...
Six Needles !?! Like one wasn't enough.
Lau Jacob one isnt enough it would hurt than itch if there was just one
Doge :3 i rather it hurt for 5 seconds then it itch for a week
dan and his muffin how if 10 mosquito bite u every 5 sec
why don't we have 6 penises?
blandantey u would get every girl pregnant every sec if u have 6 penises 😂😂😂
every creature has a certain role on this planet......and then there are these mosquitoes......
Abel Thomas their role is to kill
They r important for a group of birds who migrate to Canada, they r there main source of food and some frogs wholly depend on mosquitoes if they were dead then they would wait for them till they starve to death and these mentioned animals r food for other animals so even a slight variation in ecosystem can cause a grave imbalance.
Haha nice...
Abel Thomas they kill humans, the things that kill the earth.
Abel Thomas helps keep our population down
In elementary school in Louisiana we pretty much all learned how mosquitoes reproduce. It led to everyone I knew emptying out standing water and some created a "military force" to kill mosquitoes.
Based. We need those everywhere these flying demons exist.
2:48 the most satisfying part in this video.
I hate mosquitos but that actually made me sad

Despite how loathsome they are, you have to admit their techniques are quite impressive.
Wait, are you on their side??
Yup...we imagine all kinds of monsters and ghosts...while the ones that kill us most are barely an inch in size
That’s evolution for ya.
A friend of mine said if he got stung by a mosquito, he always wait for the mosquito to get full so he can kill the mosquito better. What a weirdo but he's still alive and still doing that stuff lol.

Props to the guy who got stung by a mosquito just for this video...

This is disgusting. I never want to be bitten by one again

But before, you did want to be bitten?
SlimePack I have 2 mosquito bites on my leg ;(

I haven't been bitten by a mosquito in a little over a year, the only good thing about the area I live hehe
who else started feeling itchy while watching this videos
Cielo Herrera me

IKR , EXACTLY!

yes. probably because I have like 5 mOSQUITO BITES ON ME RIGHT NOW
Shutout to the cameraman for shrinking down to such a minute size and recording this
Yow
Yes😂😂
Mosquitoes are so bad in Louisiana, it's considered the state bird. You can feel the needle when it pierce your skin through denim. But fortunately, with chemicals and better personal awareness, it's gotten better over the years.

wasps are useless, they are killing honeybees....
but man they're damn cool, especially hornets. they have the most cool-looking head in the universe :)
Adib Rifai No. I hate them too, but you have NO idea what kind of damage that would do.
Disabler No, they don't.
Excellent video. Professional and filled with rich information. Thank you.
“They’re so sharp you can barely feel her pushing.”
As someone who’s been bitten thousands of times, no you CANNOT feel her pushing AT ALL.
Sometimes you can. I think it depends on where they bite you and also on the size of the mosquitos in question. Larger mosquitos do apparently have more painful bites.
Me: *Casually watches this while itching my current mosquito bite*👁👄👁
same but i’m placing ice on mine 💀

Once upon a time i wanted to kill a mosquito in the air but i slapped it in the air the end
And it died
This video makes me hate mosquito even more
This video was incredible, simply wow with full of ossam informations.loved it

Me too
Got real itchy watching this
Thanks for your entertaining and informative video
Shoutout to the person whos willing to give up weeks of comfort.
cool
Yea
Tru
Thankfully it's not like an illness is 100% guaranteed though. I've gotten my blood sucked by mosquitoes almost every week for 17 years and I've never gotten sick because of them.
would still be itchy for a week tho
if it's the females biting me I'm okay with that, it's probably the most action I've seen in a while
lol
bruh
that's sad but hella rad
While the male mosquitoes are getting NTR'd.
Nope. Not worth it trust me I know
THAT is filmed insanely good that it can give very nice nightmares
For some reason mosquitoes love me in the summer time and even sometimes I'm a late autumn. Even with bug spray. Thank heaven I haven't gotten sick yet.
Camera inside in the skin

Hmmmm

Big fan sir
They have tiny cameras on needles

"Ooh! Cute baby mosquitos!"
- said no one in the history of the world
Er there is a comment with 11 likes and they said they are ''adorable''
I... I think that the larva are cute...
Doesn't prevent me from smashing them as adults though
PilotPotrzebny eww
Unless you're a dragonfly larvae, which would usually be followed by "GIT IN MAH BELLY!"
I think they're cute :3 Still hate mosquitoes tho
Ugh skeevy. Gives me the chills. One thing I love about winter. Very few bugs
I’ve never been so disgusted, I hate mosquitoes even more
"Sometimes, we take theirs" **SMASH** YESSSSSSS!
I literally,literally!! read this while that part was playing not after,as it was going on word by word. What a coincidence😅
Don't need six needles for that
😂😂😂 that would be the end of documentary.🦟👋🌝
It's actually our blood inside their stomach
I thought it was just them spitting saliva inside us
This is why I cover my whole body with my blanket when I go to sleep .-.
Same here
me too, oh and vampires. everyone knows if you cover you neck at night with a blanket vampires can't bite you.
what if they get trapped under your blanket?
WILLY LYNCH What kind of fool told you that? Its not like vampires actually need blood anyway.
Tiny Waffelz u gotta put a fan on to prevent them
Looking this up after a few but me. Was curious what they look like up close. Cool!
Back in the 70s when I was a little boy, my mom used to say that mosquitoes came from the cotton wood tree’s ..and I cluelessly played with their wiggly larvae in rain pools. Now with so many documentaries..people are more informed..
I swear whenever you smack a mosquito they disappear
frrr its so annoying
Exactly. I expect them to be dead laying on you, which looks like a black dot on your skin. But noooo, they fly off.
Seconds later you hear a buzzing noise by your ear.

These images are incredible
"From under the skin, you can see her probing, looking for a blood vessel"
How did you even film that.
Nah cuz literally I’m genuinely curious
From the dashcam of a white blood cell
Those little humans who are living inside us recorded it
Yeah I was thinking the ssme
i think that was a lab growned skin

So someone just agreed to let mosquitos bite him/her and let a whole camera crew film it all?
Yes. The researcher and her grad students volunteered (with disease-free lab mosquitoes).
thats how science works

How did they put the camera inside/under the skin?

This is actually really scary but at the same time educational because now we know that only females bite us and then we know which one to avoid and for the six needles are actually really smart for the mosquito
It's interesting how the mosquito's "saw" is so sharp that we can barely feel it. That might even be dangerous!

Mac mcskullface Yes i seen one last month, they are disgusting mf same as mosquito i need to burn them alive
Here's an interesting fact for you ZuTu. Mosquitoes can't suck blood, they use the pumping of our hearts to get it. And since they can only feed only completely fresh blood, labs that have to breed mosquitoes for research do it by having a designated person stick their hand in and letting the few hundred or thousand mosquitoes in there get their fill. How's that for a fun job?
Those are lab grown mosquitos with no exposure to parasites and disease. He's fine
@@MLGtroll365 fine but itchy
