Hello and welcome to another episode of No Such Thing as a Fish, a weekly podcast this week coming to you live from Geneva. My name is Dan Schreiber, I am sitting here with Anna Chazinski, Andrew Hunter Murray and James Harkin and once again we have gathered around the microphones with our four favorite facts from the last seven days and in no particular order, here we go starting with you, Anna. My fact this week is that jobs that have recently been added to the US Census include Doe Scaler, Automotive Window Tinter and Blimp Pilot. These are the jobs of the modern world apparently. What is a pilot? Well, we'll come on to that. Blimps are back in, baby. What is a Doe Scaler? Yeah, it's a really good question. It's something to do with baking. I see, now I understand. Thank you.

So the US Census every ten years, like a lot of places and then every year they do the American Community Survey where they still interview lots of people and the way they find out about the jobs people have got is they just ask, describe what you do, you know, what do your roles entail. And then if enough people describe a similar thing that doesn't yet fit into a category, they add that category and enough people to describe the work that goes into scaling Doe. It's amazing. To make Doe Scaler a new job. There are a lot of these jobs. There's an entire spreadsheet which I've read through. Well, I've read through the start of it. The first in the list is Abalone Fisherman. It's all in alphabetical order. You can be an abrasive grinder. I know I am. If you have an abrasive grinder profile, there is alcoholic counsellor, which sounds like it's the counsellor who's an alcoholic.

Oh, I'm your local counsellor. I just want to count on your vote. There is some people in America who describe themselves as an animal killer and also an animal eviscerator. I know. And just let me do this. This is all things from the B categories, OK? So baby nurse. Now, I'm not sure if that's a baby who's a nurse or... Adorable. Ball holder.

Ball holder. Ball shagger. Ballpoint pen cartridge tester. Banana expert. Bean snapper. Bee robber. Beef killer. Belly builder.

Biscuit wear brush. Bladder blower. Bone puller. Bone worker. Boring machine operator. Bottom cementer. Bottom filler. Bottom sprayer.

And breast worker. All genuine things that you can do in America. Beef killer. Is that for people who are still not sure if their cow's dead and they just... Just really want to really make sure. So they've been in it for, you know, some time, presumably. They're all, so they have the latest one up there, so I don't know if they're new. I don't know when they came in.

It's a weird thing because these are the census jobs. It's sort of, there's a lot of, I guess, humour as well in it where people just write a fake job down and those have been collected over the years. So these are obviously all real. But I was reading, it goes back. So the 1881 census from the British, in Britain, sorry. They have great ones that are on there. And this was tweeted by someone called Jordan Erica Weber. She found these.

So on the census in 1881, there was artificial scone maker. Body washer. Body is in your bum bum. Thanks. Spare me the medical mumbo tumbo down. Examiner of underclothing. Ferret weaver. Fish bender.

Grape dryer. Turnip shepherd. And 52 years in imbecile. I wrote this list too. Because some people just put their sort of status in life as opposed to their job. So one person wrote fatuous pauper. Another one wrote very feeble. One person, this intrigues me, wrote drowning.

I want to know about the circumstances under which the answer to the next question was... I assume when I saw that it was for rabid animals, maybe. Drowning what? You know, you have to drown an animal that's going to kill people. Why do you have to drown it? Because I was like, how are you going to kill a rabid kitten? What? Why have you turned this back on me?

Why are you going to drown it? Sorry, I'll give my rabid kitten to you next time I have one. Thank you very much. I'm actually only qualified as a beef killer, so I wouldn't be able to... They're always doing weird stuff in the olden days with animals, like contorting them into weird shapes. Like, did you mention fish bender? Is that before they invented balloons and they just had to do it with the real thing? Children's birthday parties were so traumatic.

Wait, poodle! But it was a cat before. They had a cow banger. I don't know if you mentioned that. Cow banger and then the fish bender, which you mentioned. But is a cow banger an abattoir person? I assume it must be. And maybe there were more fluid between what beef meant in that you can kill it and banging cowers.

When the census happens in the USA, there are 600,000 people working on it, which means that the acts of taking the census alters the unemployment rate by 0.2%. So when they're going through it, is it just like census taker, census taker, census taker? You know, there's a weird thing that happens with the American census, which is, I think it's done on April the 1st, weirdly, so it must encourage a lot of people to write bizarre things, except for one place, which is Alaska, where it happens on the 25th of January. And the reason for that is because by the time April the 5th comes around,

it's too cold there, so everyone's gone, they've just gone to warmer places, and no one's there to do the census. Wait, why do you think it's getting colder as the year goes on? Sorry, do you think it's colder in April in Alaska than it is in January? The reason is... Hang on, we'll spend December and January in Alaska when it's lovely, but then we'll get out of there for April. 35 years at Embersill.

Sorry, I come from Australia, our seasons are different there. Yeah, yeah, blah, blah. Actually, quite a good excuse. It's a good excuse, I haven't been there for 16 years. It's a terrible excuse. I think it's because it gets a bit warmer there, and when it gets warmer in Alaska, then the people who live there go and do things like fishing, they're in communities that go fishing and hunting,

so when you go around to take... look, join my notes. When they go around to take the census, no one's home. I think that's partly to do with it, right? I'm not so sure. People used to prank the census. This was really exciting. In 1911, in the UK, was the first time that people got to actually hand-write their own responses,

so that's quite cool for a number of reasons, because it means you find very famous people in there, Winston Churchill is in there, just listing what he does, but there's also, for example, a man who... it was only the head of the household who wrote the responses, so one man listed one of the occupants of his house is Peter Tabby, whose occupation is Mouser, and his nationality is Persian. And the census representative has crossed out this line.

You can see the cross-out line, and Britain beneath it, this is a cat. They would drown it now. And we're going to have to move on in a second, guys. Oh, can I just say some things that... other things that have been written on censuses? So the people who are taking them write interesting stuff. In the 19th century, in America... Oh, in the 19th century in the UK this was,

the censor-taker would go round, and often they'd ask the questions and then write down the answers themselves, and it was about taking a census of everyone in the household, but sometimes you had a homeless person who was camping out in a barn, or things like that, so for instance, in one census, someone was recorded on the census, but he just wrote next to him, drinking slept in shed,

unclear whether he was a member of the household. Another one was recorded as, home but dead. Would you want someone to clarify, if you go, oh, it's James in, you want someone to clarify? I was like, yes, but he is dead. There was one really snooty one in Hampshire, in the Hampshire Parish Record, actually, that someone found on 9,

and it was recording the existence of the baptised bastard child of Mary Brown, gotten of John Smith, brackets, so she sayeth, closed brackets. Well, because it was often Vickers who recorded it, and they were very judgemental, so the very Reverend Dr Peter Scrimshire would got to go around doing all of his parishes and responses,

and so he found an unmarried mother, and he just described her occupation as man trap. OK, it is time for fact number two, and that is my fact. My fact this week is, heavy metal musician Tony Iomy began playing heavy metal guitar with two metal fingers, because he lost his real ones while working at a metal factory. This is Tony Iomy from the band Black Sabbath.

I got this fact, I just have to say, it's one of the best books I've read in a long time. It's called A History of Heavy Metal by a friend of ours, Andrew O'Neill, who's a comedian, but he's written a proper history of heavy metal. It's just brilliant, packed with facts, lots of funny jokes. The opening line is one of my favourite opening lines to a book. He says, this is the opening line,

there are two types of people in the world, people who like heavy metal and dicks. So Tony Iomy, he was working in a metal factory, and he was asked to do a job that he had never done before, and he was meant to quit that very day, and he in fact stayed at home, and his mum made him go in to do the job, and he was working, and suddenly when operating machine,

the two tips of his second and third finger were chopped off. The bone was still there, he went to the hospital, and they said, we're going to have to saw the bones off, and he was very depressed, and a friend of his brought in a record of a guy called Django Reinhardt, a very famous guitarist who could only play with two fingers on his guitar because the rest were paralysed, and he thought, OK, I can do this.

So he started experimenting with ways that he could make tips for his fingers so that he could start playing again, and the first iteration of that was metal, he used metal to make that, then he moved on to soldering a cap from a soap bottle down, attaching some leather around it, and using that. And what's extraordinary about this is worth saying is that Tony Iomy is credited with inventing heavy metal.

Black Sabbath is said to be the first heavy metal album, and it was because of this situation that he couldn't play with regular strings, so he had to buy banjo strings for his guitar, and by lowering down the notes, he started playing the first metal riffs, and that's why we have heavy metal, because he lost two fingers in a metal factory.

That is unbelievable. It's almost like he set it up. It's too perfect. I think he did it just to get his mum back for forcing him to go to work. The only thing I know about Tony Iomy is that he was pretty nuts, I think. Black Sabbath did behave in a gratifyingly crazy way

back in the day, like you think they did, but he once exploded Richard Branson's prize carp. Which is quite... Yeah, they went to say at Richard Branson's house, Black Sabbath, and he decided to launch some fireworks into Branson's lake, where there were his prize carp, which do cost so many thousands of pounds,

and he exploded them all. Oh, occupation, carp detonator. Do you know that heavy metal has a birthday? Oh, stop it. No, it does. What is it? Because Black Sabbath's first album was seen as the very first heavy metal album,

and it was released on Friday the 13th, in February 1970. That's the birthday of heavy metal. Really? Yeah. Surely deliberate. Metal probably has more sub-genres than any other kind of music, I reckon.

There's a big list on Wikipedia. They have National Socialist Black Metal on the far right, and Red and Anarchist Black Metal on the far left. They have Viking Metal, War Metal, Unblack Metal, Sludge Metal, Pirate Metal, Space Metal,

Grindcore, Deathcore, Gorgrind, Deathgrind, Pornogrind, Mathcore. Mathcore? Mathcore. No. Mathcore. Mathcore.

Just maths. Very loud, shouty maths. Speaking of school subjects, they have Latin Metal, but unfortunately it's about Latin American music, not all of Latin. Do they have Geography Metal? Wow.

I wonder if it's like the people's front of Judea and the Judea's people's front. Do you think they all hate each other? Because they sound pissed off about something. From the book that I read, the suggestion that, yeah, the split groups are, they don't think there is, you know, hardcore as each other.

Like Glam Metal, Motley Crue and all that sort of famously wearing lycra and stuff like that. Glam? Sorry, I thought you said Glam Metal. That's another subgenre. Well, they had, in The Simpsons once, there was a Simpsons episode where they quoted

a Judas Priest song and they referred to it as Death Metal and they got so many furious letters from metal fans saying Judas Priest is not Death Metal that in the next episode of The Simpsons, the message that Bart wrote up on the board, what, you know, he writes on the blackboard, the message was Judas Priest is not Death Metal. Wow.

Some people who are, some things that do like Death Metal is sharks. Oh yeah. Typical, let's face it. There was a team from the Discovery Channel in 2015 who wanted to attract a large female great white called Joan of Shark. And they put this speaker in the water

and played a load of Death Metal and it didn't attract Joan, but it attracted a load of other sharks. So it does seem like they like the vibrations of Death Metal in particular. Wow, very cool. I have a fact about, it was related and you'll see why, but it's about Mozart, it's not about metal,

but it's about, I was looking up musicians who've overcome impairments basically. So Mozart started going Death at the age of 26, which is a huge problem obviously, but it's, sorry? Beethoven? Yes, it is, yeah, great. Shall we begin again?

So, Beethoven started going Death at, no, stop it, no, come on. How's that going to sound? What am I going to say? Beethoven started going Death at the age of 26 and it started with tinnitus and there are lots of theories as to why he had the tinnitus. So the theories as to why include

that he may have had lead poisoning, or syphilis, or typhus, or that it was due to his habit of immersing his head in cold water to keep himself awake. Wow, yeah. Wait, and that's, so the relationship to the previous fact is the sharks are also immersed in cold water? Correct.

Got it. I couldn't tell you that at the beginning because it was the end of this fact. Spoiler, yeah. Spoiler that, brilliant fact about Mozart or Beethoven or whoever it was. We need to move on to... I've got some stuff about fingers, people who've lost fingers.

So one group of people who've lost a lot of fingers are cavemen and women. So... Cave persons. So do you mean historical ones? I do. I don't mean people who live in caves today. I mean... How on earth do we know this?

The main physical impression that we have of people who live particularly in caves is hand prints that were left in lots of caves in France and in a few other countries. So there's the Gargaz cave in France which has 231 hand prints left by the people who live there. There's 114 missing, at least one finger. And there are other caves where it's also 50-50.

The hand prints are there, at least one finger. And we think they were all working in metal factories, too. Yeah. It was the Bronze Age, there was a lot of it going on. There's lots of theories. So one is that it was a punishment or one is that it was a kind of ritual thing. Some people think it was frostbite

and some people think they were just folding down their fingers. They were doing the metal sign. Well, the ancient Greeks used to cut off dead people's fingers. So this was their paranoid that people weren't actually dead and they'd cremate them or bury them when they were still alive. And so to check, they'd cut off a finger. The reasoning being that if you weren't dead, then you'd say something.

Well, we know he's at home, but we're not sure if he's dead or not. You know, if you do the peace sign with your two fingers, if you do that and you're photographed from within nine feet on a smartphone, your fingerprints can be stolen, reconstructed, printed out and used to access your stuff. No.

Yeah. Wow. I know. We should say that... I don't know if they gave us permission to say this, but I'm sure they did. When we were at CERN earlier, we were talking about the idea that you get your eyeballs scanned

and checked to give you entry to places. I think it came up in Angels and Demons in Tam Brown, did it? That's right. And so apparently they tested it out. Some scientists tested that out to see if that does work. And it turns out it doesn't. So if anyone was going to murder somebody to get their eyeball to let them into a building, it doesn't work, no point.

Yeah. In fact, don't use any of Dan Brown's works as a way to live your life. Okay, it is time for fact number three, and that is James. Okay, my fact this week is that in 19th century Romania, there were people who sold shadows and they would sell your shadow without your permission. And then you would die less than one year later, according to superstition.

So in Southeast Europe, there used to have this tradition where you could use your shadow as a sacrifice when making a new building. Okay, so basically you would stand there in the sun and then they would put where your shadow is and they would put the first block there and then they would build the rest of the house and supposedly it would stop the house from falling down. But like I say, unfortunately it would mean

that the person whose shadow it was would die within a year, according to superstition. So people didn't really want to do that. And so what they would do is they would sneakily entice people to stand over next to a building site and say, oh, just stand over there and you're like, you're not going to stop building the house here, are you? No, no, no, no, no.

And then they would do it and then they would die within a year, according to superstition. And then people kind of got wise to that and you had shadow traders who would kind of stand next to you in the street and they'd see your shadow and then they'd sneakily measure it and then they'd give the measurements to a builder and that supposedly counted.

If they put the measurements in their foundations then that would work as well. And so did these people go home and then suddenly look down at the floor and say, oh my god, I've got no shadow? No, unfortunately the laws of physics stayed the same. They mostly do. Apologies to the CERN guys who are in. Do you know what the precursor to this was though, this tradition?

This was actually a more humane version of what came before it, apparently, which was that the idea was that you had to ward ghosts and terrible spirits away from this new house. So what they used to do was either crush someone under the foundation stone of a house or put a living person in between the walls of the house so that they would die there and their spirit could haunt it and scare away other spirits.

I can see where the dying within a year bit comes down. Not according to superstition at all, that's just... You wouldn't want to buy a new-build house in 19th century Romania, would you? Was that someone at the door? No, that's just the guy in the wall, he's still dying. You know, whenever any man goes to look at a new house all they do is kind of knock on the walls, don't they? And no one has any idea why they're doing it. It's so ritual as old as so you're just finding the guy.

So I was looking a bit at shadows. And I was looking at shadow puppets. So most shadow puppet shapes were invented by the same man. Really? This is amazing. So he was called Felicia Truy and the art was called Chinese Shadows or ombres chinoise. And he popularised it basically and he wrote a book saying, I can do everything, I can do the elephant, the bird, the cat.

There were a lot of people as well. There was the volunteer, the fisherman, the preacher, the jockey, the rope dancer. He did an entire play which was just him doing hand shadows. And this was, it was really, really popular in the 19th century and he had one other trick as well. His other art was chapography. Chapography. Can you guess what that is? Writing? It's hats.

He would get a single piece of felt, a single normal piece of felt. He would fold it into different shapes repeatedly to make different kinds of hats. And this was really huge. This was the most exciting thing. Sorry, this was before the internet, was it? There is actually this footage of very late 19th century chapography happening. It does sound cool actually. He takes it off, it's a later practitioner, he could do 35 differently shaped hats

with a single piece of felt. When he puts on everyone, he does a little face to say, look, this is the nun, or this is the fisherman, or this is the other person. But it was not... Again, it's just the precursor to the balloon contorter, isn't it? Children's birthday parties have always been the same. Shadow puppetry, that is the reason they called it Chinese shadow puppetry. It is because China did it for 2,000 years before this guy started.

But they didn't use their hands because they made wooden puppets and then cast their shadows onto them. This is the plagiarist. Oh, here comes the lawyer. In China there is evidence of it happening since the 2nd century BC. And the legend always went in China that the reason it was invented was because there was an emperor, the emperor Wu Di. And his favourite concubine died and he was really devastated.

And so one of his mystic assistants started shadow puppetry in order to convince him that his concubine had come back from the dead. So he just made the figure of his concubine and cast her shadow on the wall and was like, look, she's just over there and she's in the room. And apparently that made it cheer him up no end and it caught on. I don't know if he fully believed that she'd come back. He could never quite have a conversation with her again. It caught on and then it was brought to Europe by Genghis Khan

or by Genghis Khan and the Mongols sort of marauding armies. That wasn't their main aim though, was it? Spread the shadow puppetry. That's why they did it. He's always painted in a bad light. He was just trying to spread the arts and culture. This one is the invading horde who will burn your village. The invading Mongol armies travelled with a horde of shadow puppeteers

to make them entertained. They did not. They did. They had shadow puppeteers in their troop. Wow. Even the Mongols had an off day. Wait, do you mean a day off when they'd enjoy the shadow puppetry? I mean a day off, not a bad day.

Do you know they've invented buildings, skyscrapers that don't have shadows? No. This is really cool. So using computers, they've done this. You need two of them. So you have these two big buildings and then the light comes on and they kind of reflect off like a mirror, but then one reflects onto the other and the other reflects onto that one.

And basically the light just very slowly goes to the floor and there's no shadow at all. It only works if they're exactly on the Greenwich Meridian in London. So you have to build them exactly there in the centre where there already is a museum. Yeah. But in theory it works. Does it have a use? That's the question. The shadowless building.

So the idea is if you were to build it, you could put it anywhere and slightly change the metrics and you could build it in a different place. These won't only work in Greenwich, but other ones could work anywhere. And let's say you want to build a massive building near Central Park, for instance, in New York, but you don't want to have a massive shadow over the park because people want to sunbathe. You can put these things there and then they won't be getting in people's way. And the other thing is there's a lot of buildings that are now being built that are solar powered. And so if you've got a solar powered building or a house or a farm and suddenly a big building

is just knocking out the sun, you can't operate. So there's new laws that are being put in place to say that you can't have a shadow come over you if you're... Wow. Because they have a tax on shadows in Italy in some places already, which I thought was absurd, but it's sounding more sensible. But this is small business owners in, mainly in a place called Conegliano in Italy, have to pay local tax on the shadows that their buildings cast. And it's like 100 Euros per annum.

And they didn't really know they were paying until recently. And they went, what the fuck? I'm paying for my shadow. And the idea is that if your building casts a shadow on someone else's land, then you are occupying that person's land. What? And so you have to pay a tax on that. That's really interesting. You can get a shadow boyfriend in Japan.

That's good. This is kind of like the Chinese emperor thing, actually. So it's a device that was allegedly at the prototype stage last year, although I don't think it's made it very much further than that. But it projects the shadow of a man onto your curtains. It's basically what Kevin does in Home Alone. If you remember that, he pretends he's hosting a party. Is that a boyfriend or a burglar?

Yeah. No. It's the burglar sees it, and he sees, oh, well, there's a big strong man there, so I won't try and burglar that home. And you can choose the activities. There is a range of activities you can get them to do. So weightlifting, playing guitar, boxing, just swinging a baseball bat around feels like overkill.

And there are more realistic ones where they're just sitting at a computer for ages. But if he's on the other side of the curtain, which is right against the window, right? No, no. So you're looking at the building from outside. Yeah. And as the homeowner, you project the shadow onto the closed blinds, or the closed curtain.

So if someone looking from the outside thinks they see a bodybuilder. Yeah. What's your beef? Well, who hangs out in front of a curtain by their window in a... A rubber? Exactly. So you'd probably think the house was being burgled and report it. Oh, wait, lots of people hang out in front of their window.

Burglars don't break in and just start doing some weightlifting. Not the weightlifting one, but it would be great if you could get a shadow thing to project the image of someone robbing your home. Because then the burglar will see it and think, oh, someone's already got there. Yes. Yeah. OK, we need to move on to our final fact of the show,

and that is Andy. My fact is that some aphids fix their homes by exploding themselves and plastering their own bodies over the holes in the walls. So this is a species called niponafis monzani. And this is a scientific study by someone called Takema Fukatsu. And they live in very big lumps on trees, these aphids, called gulls. And sometimes these are invaded by caterpillars. And these young aphids, they're called nymphs,

technically they are dispatched to assassinate it, to stab it to death. And as those guys get fighting, other little aphid soldiers rush there and their job is to explode. They're just full of fluid and they get there, and then there are these two holes near their bottom and they just explode these globules of goo all over the place. And some of them get stuck in the glue as it hardens around them. So they're trying to mend the hole in the wall, fix the breach.

And others release so much fluid, they shrink to a third of their original size. And then they're just these little shrunken balloon aphids who can't do anything, and they die. That's a sad ending to that story, actually. It's a sort of heroic sacrifice, I guess. Yeah, you can look at it like that. It's really amazing though, isn't it? I think the way it might have evolved is that originally these fluids would be helped

if they just had like a cut on their elbow or something like that. It was almost like a scabbing thing, like a human would, but then it's kind of got more and more and more and more so that now it's learned to scab over a plant rather than just the aphid itself. Which is amazing, isn't it? Some of them seem to go outside the home, and so some of them do the exploding, and then some of them just secrete the gluey stuff and paste it on.

But a lot of them do it from outside, so then they paste themselves outside their own home. That's tragic. And then they can never get back in? Can't get back in, they're buggered, yeah. That's the real idiot kind of construction worker, isn't it? What have I done? They also do this exploding against predators, some of them.

So cabbage aphids, they get chemicals from cabbages, and they can mix certain chemicals, and if a ladybird or something tries to eat them, they can explode, and it's almost like a mustard gas that goes into the ladybird's eyes and then it runs away, and they can, well, they are dead. Oh, they die in the... Yeah, but they've saved their mates.

That's the important thing. They've got these two chemicals in different bits of their body, and when they're attacked, they combine them. And that's like in Die Hard 3, that's the bomb in Die Hard 3. That's the structure of the bomb in Die Hard 3. That's amazing. They're incredible aphids. Can we talk about Die Hard 3? Yeah, sorry.

No, but they are extraordinary, aren't they? I was reading this thing about them, which is, so they'll all exist on a plant, a colony of them will exist on a plant, but they don't have wings, so they all hang out there and... A lot of them do have wings, but some of them don't. Yeah, so let's say with the species that don't have it, they'll be on this plant and they'll suck it dry or it'll get too overcrowded and they need to move on.

So when that happens, they produce a generation of the same species with wings to fly away and then they land on another plant and then they lose the wings again and just hang out there. They can just suddenly have a generation of winged aphids of their species. They have weird reproduction because they sort of alternate between sexually reproducing and then the women going, we can't be bothered to use men, and then asexually reproducing, which mostly they do the latter, don't they?

But when they're on plant, sometimes there'll be a whole bunch of aphids on a plant feeding on it. And then they see a deer or something coming towards the plant and it's going to eat it, so they all need to throw themselves off like a mass leap. And then they get to the floor and the little ones piggyback on the bigger ones to escape. So you see the little aphids climbing onto the older aphids' backs

and this is when it becomes more individualistic because the scientists who have watched this say the older ones are there trying to scrape them off as they're trying to escape. Off me! But they do do it. That's amazing. And you were saying how they can kind of reproduce without males.

The females, they could do that up to 41 generations without having any sexual acts with a male. But it does mean that if you had one aphid, one female aphid in a room, and no aphids died, then there were more than 1.5 billion billion billion aphids at the end of the season, which means that the earth could be covered in a layer of aphids 149 kilometers deep within a year. Wow!

So they're just all, most of them are dying? Well, that's why Ladybirds are so great. God! God, that's amazing. Is it true that they, sorry Andy, is it true that they are basically born pregnant? I kept reading the thing. That's extraordinary.

And then, yeah. They give birth to offspring which already have embryos. Which are really like Russian dolls. They're just like, there's a tinier aphid. Yeah. Three times over. Yeah. And then they just lift the upper torso off

and out comes the smaller version. So the thing they really like is sap. They love sap. And they also get called sap suckers. That's how much they like sap. And they excrete this thing as they feed, which is called honeydew. And they have to eat so much plant sap

because they need various nutrients and they can only get those nutrients in the quantities they need by ingesting a huge amount of sap. So the giant willow aphid produces four times its own body weight in sugar every day that it's excreting. So that's the equivalent of a human leaving behind a couple of bathtubs of water every day with 300 bags of sugar inside.

That's what they're doing each day. Wow. And also other animals love this honeydew which is their aphid excrement. So sometimes if bees can't get nectar they will just lick up aphid poo instead. Because it's very high in sugar. It's fine.

It is fine. It's fine, but it's not quite as good as nectar, is it? It's not quite as good. Honey can be made of plant sap that's been filtered through an aphid's bum and then forms it up by a bee. But the reason that their sugary excretions are most important is because of this amazing

relationship they have with ants, right? That you can't talk about aphids without talking about ants because the ants love their honeydew which is such weird euphemism for poo. But so they have this really symbiotic relationship with ants and it's hard to know who's winning and who's losing in that relationship. And so sometimes ants will bite off aphids wings

so they can't fly away. But they can't kill them because they need to keep on licking this honey stuff. And so that means they defend them. So when other attackers come and they want to eat their aphids then the ants will fight them off because they'll stop anyone killing them. There's this really cool ant actually

which we think is the first meat farmer aside from humans. So it's an ant that farms aphids but for their meat because these are aphids that don't actually produce this sweet stuff. And so it's called the melisotarsus and it's about three millimeters long and basically they keep all these aphids together

inside the bark of trees and they sort of farm them and they gradually eat them. But what's quite cool about these ants is they've obviously got six legs but one of their pairs of legs, their middle pair points up, not down. What? What use is that?

I guess if you fall on your back you can turn yourself over again. No, it's because they're always burrowing through tunnels in trees and so it helps them get their two feet on the roof while they've got four feet on the ground. That's amazing. It's cool, right?

And also we're not totally sure they eat the aphids because they really hate being spied on. They're very private, like a lot of us. And so we've seen that they keep the aphids sort of farmed inside the tree. But whenever scientists drill holes in the tree the ants immediately block them up again. So we haven't been able to watch yet.

That's amazing. We have to wrap up in a second. Some aphids defend themselves by having sex with other aphids and getting STDs and they actively seek out STDs because they give them superpowers. What superpowers do they get?

Well, it's a very specific superpower. Wasps like to lay eggs inside aphids and this is a big problem obviously because no one likes to have an egg laid inside them by a wasp. But the good news is that there are particular STI bacteria which destroy developing wasp grubs in your body. So the only way for a female to protect herself

is to seek out a male with a sexually transmitted infection. But how does she know? It's on its Tinder profile or something. I don't know how the female knows that the male has it. So she's been parasitically implanted. I think it's before that. She might be prophylactic kind of method.

It's like a condom rather than the morning after pill. Except the condom is getting an STD. Do you know that due to aphids or aphids had a real thing with wine in the 1900s, early 1900s and they really started attacking all the wine in the world. They were eating all of the roots and it meant that the French wine industry

almost went out of business and actually all of Europe did. And what they found is that the aphids loved the roots of French vines and other European vines but they really hated American vines. And so these days almost all French wine even though it's French grapes

they're grafted onto American roots. And so actually most French wine is actually half American. Wow. We're gonna get lettuce. Glad we didn't do this fact on our Paris bit of the tour. Okay, that is it. That is all of our facts.
