"“Just like you would eat eggs for breakfast, the sea spider grazes the surface of its body, and it munches all those bacteria for nutrition,” said Shana Goffredi, a professor and chair of biology at Occidental College in Los Angeles and the study’s principal investigator."
I really don't think I would put eggs all over my body to graze for breakfast, but that's an interesting image.
sebastiennight
I always consider this kind of weird unnecessary metaphor a big sign that the content was generated by ChatGPT, and I would be willing to bet that this professor was interviewed via email and got some "help" in writing her reply.

Yeah, something weird has happened to these quotes because nobody would intentionally put "use" in brackets like that.

> In this symbiotic relationship, bacteria take up real estate on the spider’s exoskeletons, and in return, the microbes convert carbon-rich methane and oxygen into sugars and fats the spiders can eat
Doing all the work. Microbes get no respect.
But also, can we attach these to natural methane producers? (Eg decomposing stuff or cows)

I think you're unfairly dismissing the massive amount of nanotech R&D and energy it takes to develop and operate the bazillion-unit cooperative mobile megafortress those bacteria are happily renting.

The real question is did they build it using agile or waterfall?
BLKNSLVR
It took a billion years and ... mostly works.
I'd guess waterfall then.
drjasonharrison
test driven development!
_0ffh
Obviously, it was good ol' trial-and-error. Or rather, trial-and-the-least-error.
gexla
With all tech impressive tech, do the spiders feel it's beneath them to do those conversions themselves?

> Doing all the work. Microbes get no respect.
Maybe not in the mainstream?! But for many years people have had jobs specifically trying to get microbes to do useful work for us. [0]
Look up key terms like "directed evolution" in microbial research - which to me sounds like a fancy phrase for "breeding". But when breeding cycles can be measured in minutes across millions of units for something so small we can't see it... it kind of is a different thing so I guess it's fair to differentiate it.
> But for many years people have had jobs specifically trying to get microbes to do useful work for us.
Well, you know, there's brewing and bread. I like beer. I like sauerkraut. I like bread.
Insulin is handy. So is human growth hormone.
blacksmith_tb
I would guess that they've evolved for the conditions around the seafloor, so rotting trash piles or cow stomachs might be a stretch (though cows might welcome some extra sugars, unlike garbage - though I am sure some other microbes could step in there).
aaron695
They are in cows and people and landfill as you'd expect.
Why would they not be?
If you want to increase their number you need to give them a better environment.

What’s striking here isn’t just the spiders it’s the idea that living creatures can directly plug into chemical energy from the Earth without sunlight. That’s a whole ecosystem powered by methane instead of photosynthesis.
Elaris
It’s funny how something as strange as a methane powered sea spider can make you rethink what “life” even means. Energy, structure, feedback it’s all there, just in a form we weren’t expecting. The deep sea keeps humbling us.
rolisz
Someone asked 40 scientists what is their definition of life and the clustered them with LLMs. The results were incredibly varied: https://arxiv.org/abs/2505.15849

This is like if Project Hail Mary and The Abyss teamed up to write a headline.
earnestinger
I enjoyed Project Hail Mary a lot. Would you recommend me “the Abyss”?
VikingCoder
The Abyss is a movie by James Cameron, who also made Terminator, Terminator 2, Aliens, True Lies, Titanic, and Avatar.
"The Abyss" is about a deep sea crew that encounters ... aliens...?
And yes, in general, I recommend The Abyss. It's definitely not the same as Project Hail Mary, but it does have similarities.

At first I thought this was an Oil Gobbler[0] situation, only this time it's real!
Can we put their genes into domesticated animal feed and knock it off with all the climate-hostile farting ?
palmfacehn
Black Smoker ecosystems may be remote, but they are still observable. I've often wondered about the possibilities for microbial ecosystems deep within the earth, at high temperatures and pressures. There could be implications for the formation of hydrocarbon deposits.
SiempreViernes
Ecosystems that long ago branched off from the ones we know of maybe, but I think small isolated pockets are unlikely places to find much innovation because they can much more easily fall into stable states where nothing much evolves.
WalterBright
Hmm. Does this mean we can seed life in Titan's methane seas?
inetknght
Moreover: does it mean there's already life in Titan's methane seas?
mr_toad
Surface temperatures are below -180C. If there is life then their chemistry would be very different from Earth or any water based life.
inetknght
Surface temperature, yes.
But deep in Titan's ocean? Not so much.

> Even if 80% of the population are eaten (by the spiders), it’s worth it for the 20% to keep surviving and reproducing.
Some symbiosis
Float away from the methane and die, or if lucky attach to a predator that lives in the methane that will harvest you for consumption but not before you reproduce
smadge
It’s like the symbiotic relationship between humans and livestock.
WalterBright
These sorts of relationships are common in earthly life.
It's not about being nice. It's about reproductive success, by any means.

Sure, but there's a more conventional term for this kind of symbiosis. Usually it would be called "farming". Humans have the same kind of symbiotic relationship with pigs, or wheat.

“Just like you would eat eggs for breakfast, the sea spider grazes the surface of its body, and it munches all those bacteria for nutrition,”
I don't of anyone in history that had chicken eggs growing on their skin.
9dev
Yeah, that phrase sounds like it was written by an alien not particularly familiar with eating habits on Earth…
dotancohen
Nobody specified that these were _chicken_ eggs. Though that thought leads me in two different directions, neither of which is fit for polite company.
I hope the notion of methane mining the ocean floor never takes off.
clarionbell
What do you think are all those deep sea platforms doing right now? We have been mining hydrocarbons from sea floor for decades now. Mostly burning the methane as "not worth the extra pipes" by product.
odie5533
Who would study sea spiders? You'd have to look at and think about sea spiders all day. That's terrifying.
kirubakaran
People who are not terrified of spiders, of course.
Arachnophobia (even the mild variety) is not universal. I know some people who think spiders are cute. It takes all kinds, I guess.
schmidtleonard
Most people can get on board with jumping spiders. Big eyes, recognizable behavior, fuzz like fur, aspect ratios that aren't foreign to mammals. But if they mean knobbly things that look like they came out off the sea floor / out of an alien film, yeah, I'll grant them that they have a special skill if they can find those cute.
housecarpenter
As a non-arachnophobe, I don't find spiders of any kind to be cute. But I also don't find anything about their appearance or behaviour to be unpleasant or scary. They're just aesthetically unremarkable. Similar to, say, fish---I don't think most people will look at a fish and think either "ooh, so cute" or "weird alien thing, get it away from me", they just see a fish and don't really have any emotions about it.
Freaky, except they're only a few millimetres in size and considered harmless to humans.
It would be hard for a spider of medically significant size to suck down their exoskeleton like that.
kirubakaran
Lots of fears are visceral, but even if we were to allow only verbalizable fears, one could imagine the arachnophobes thinking "what if this tiny spider burrows through my eyes or ears and lays eggs inside my brain, and then all the baby spiders stream out of my mouth and nostrils"
imp0cat
Why? You could probably wear those much like you would a ring or a bracelet.
I do believe there also is a song about them. It goes something like this: Anywhere you go, you always take your spider, your spider with you... ;)
colanderman
Nope jumping spiders are the worst kind. So are big fuzzy spiders.
They're not insectlike, but in some weird uncanny valley between insect and mammal.
And they can JUMP onto you.
Nope nope nope.
x______________
Jumping spiders are quite intelligent and playful.
They will play 'catch the laser dot' with you like a cat does or even do little mating dances when you prop a mirror in front of them.
YouTube has many videos of such activities
Have a bit of fun with them next time you see one and your next encounter will not be so unpleasant!
-ex arachnaphobist
nhecker
I like to imagine that they don't jump, they _teleport_. It's fascinating to watch them blip out of existence in one spot, or one orientation, and appear in another location in the same instant. Forget what it must be like to be a bat[1], what would it be like to be a tiny jumping spider?
I love spiders.. they're like mini steampunk machines.. powered by what is effectively hydraulics. (that why their legs curl up when they die.. the loss of hydraulic pressure)
fracus
This reminds me of a thought about veterinarians. What kind of person would be a veterinarian? A good portion of the job is putting down animals and treating suffering animals that can't speak. Either the vet is a psycho or a pure heart who can tank trauma all day long. I find suffering non human animals to be more traumatic as they can't speak, just emote. Anyway, thank goodness for vets.
dhosek
It’s not quite that bad. My brother was a veterinarian and in his case, it was very much a vocation thing: he knew he wanted to be a veterinarian by the time he was maybe 10 or 11 and took a remarkably direct route there. The vast majority of the work was fairly routine care, and he had a unique gift for connecting with animals (most of his early career he did house call veterinary work and so many clients would talk about how their cat or dog was terrified of strangers but would just climb into his lap and let him do whatever he needed to do to care for the animal, whether it was trimming nails, examining teeth, taking blood or anything else). Euthanasia was something that he felt, but was able to get through for the other aspects of the job.
I have an ex who became a vet (kind of a surprise in that when we were dating she was an artist) and she has a house call practice with a lot of her work being euthanasia. I don’t know how she can manage that emotionally, but I’d like to believe she’s not a psycho even if she was the one who ended the relationship.
sebastiennight
Just be happy you got out before she was a vet and knew how to practice euthanasia
lukas099
Sadly, vets have a high suicide rate. This study found 1.6x the general population rate for male vets and 2.4% for females.
I have a vet friend that I talk to a lot. One thing that struck me was how many clients will bring in a dog with a serious, obvious malady (the one I remember was a dog with maggots in its anus, sorry for the visual) and will be like, “are you sure he’s in pain? He hasn’t been crying all day”. And it will be evident that this has been happening for weeks.
nhecker
And then some people will bring their healthy pets into the clinic for euthanasia because they're going out of town for a while and don't want to arrange for care of the animal in the meantime. Or because keeping the animal even if they are not leaving town has become too inconvenient. Some people are pieces of work.

(2.4x, not 2.4%)

There's also that pet-vet jobs are rare compared to ag-vet jobs.

Know thy enemy.
NoImmatureAdHom
Wouldn't it be "thine" enemy?
tessierashpool
this is correct, because "enemy" starts with a vowel, but it's a fairly gratuitous translation either way, since "know your enemy" comes from Sun Tzu
o11c
Fun fact: the King James Version of the Bible has several errors where it uses "thy" before a vowel sound. This might vary by edition, but I've verified some in a scan of the 1611 "he" bible. Unfortunately it's blackletter which I can't read quickly, and I really don't trust the OCR.
Semi-manual verse counts from a random digital copy I have convenient, before 'e' only:
(2 thy, 2 thine) elder
(2 thy, 0 thine) elect
(19 thy, 3 thine) estimation (most in the same chapter!)
("thy ewe" is correct due to pronunciation)
(1 thy, 0 thine) exceeding
(1 thy, 1 thine) excellency
(1 thy, 1 thine) expectation
(2 thy, 110 thine) eye
2 John, being short, is the only book that exclusively does it wrong. The other errors are in Genesis, Exodus, Leviticus, Deuteronomy, Job, Proverbs, and Ezekiel, all of which also use the correct form.
(it also has errors before other vowels and 'h', though the 'u' one is debatable)
I really don't think I would put eggs all over my body to graze for breakfast, but that's an interesting image.
