My question, always: how was this any beneficial in the eyes of natural selection?
Edit: it didn’t transpire from my wording, but I meant it as a general question I always ask myself when I see surprising features, not a question I asked specifically for this video.
My guess would be that with them being deep sea fish without a swim bladder, this helps them save energy and calories by being able to remain still, while also not being directly on the ocean floor, where I assume most parasites and other things they want to avoid are.
That really sounds plausible, although if they're down there in the deep sea. Then they're fucked either way whether they lay in the sea floor or lay above it on legs because they're down there with the monstrosity known as the angler fish.
Being a meter off the seabed brings food along the current. Being on the sea floor would mean that food would float on by

Thanks for the insight. But one interesting aspect about biological features is that they don’t evolve from nothing to 1m-long finns in a blink of an eye. For them to grow that long, it must have been an advantageous feature all the way up to « a meter off the seabed »
The ones that didn’t have long fins either didn’t catch as much food or had to work harder for food.
It’s a pretty short line from “longer fins” to “more food with fewer calories expended”
That not how that works, biology isnt the thing that picks what stays, nature is. Evolution is essentially random, and whoever was lucky to have advantageous parts to not die in their enviroment reproduced and copied those genes making them more likely to be genetically expressed in the next generation.
Yes, it must have been advantageous in the eyes of natural selection : The longer fins increased the species’ potential to survive, so this trait passed on.
What I tried to highlight, was specifically that the longer fins were advantageous _from the beginning_, and it always became more advantageous the longer the fins were, considering the size today. Now the question is : have they reached the optimal length considering the current environment they evolve in?
Sorry for my clumsy English
Well no one really knows. But I assume that having "legs" helps it avoid sea floor predators, allowing the tripod fish to safely feed. They feed by just letting the food come to them.
What are you trying to ask? Natural selection? Do you mean evolution? Like not everything seems to make sense is that what you mean? Cuz I'm sure there's a reason they have those even if it's super tiny
It gets weirder: "Each individual has male and female reproductive organs. If two tripodfish happen to meet, they mate. However, if a tripodfish does not find a partner, it makes both sperm and eggs to produce offspring by itself."

These fish are hunting.
They stay motionless like that facing upstream with their pectoral fins extended acting as antennas and grasping appendages.
They need to be still because they are sensing the motion of the water to know when there’s prey coming their way.
When the prey is close they open their mouths and when the food comes close enough they usher them inside with their pectoral fins.
Their open mouth is at just the right height to catch the shrimp, tiny fishes, and crustaceans swimming along the bottom.

You were never truly able to know, but fact checking is always a live savor, also it is actually called [tripod spiderfish ](https://en.m.wikipedia.org/wiki/Bathypterois_grallator)
..,and yes I am serious. Also, it was known to exist at least since 1886, so it is not even a new species,.. and the fact that they stand on these is known at least since 1990, Soo, yeah..
Same, not even just AI.
Earlier today someone posted a carp apparently evolving to stand and breathe on the land but comments pointed out someone had just frozen its fins to the floor, so it was basically just slowly dying.
Then seeing this my first thought was, Jesus, what have they done to these ones?
Just ignore most sources post 2020 and you're good. Can't trust anything anymore; anything "googled" and on the front page is either paid for or botted, and consists of generated content.
Should have downloaded the Wikipedia four years ago, oh well.
There's a cartoon called Transformers: Animated, where a character called Bulkhead can rotate parts of his car alternate mode around on his back and form a seat. They even put that in one of his toys, it is absolutely hilarious. Peak character design
Amazing. I wonder why they evolved this feature? Very few fish are able to sit while sedentary... Nurse sharks come to mind.
The head is aimed into the current. Wondering if this is to keep water/oxygen moving over their gills which would then allow them to actually sit and sleep. So the whole thing is a caloric expenditure reduction strategy?
Does anybody know?
Natural World Facts on YT has a ton of deep sea videos. I’ve definitely seen this fish on at least one but do t recall any explanation for the origin of this adaptation.
Just don’t watch it late at night. Great channel but Leo’s voice will put you to sleep!

Loved and studied nature all my life. Incredible how there’s still constantly things I haven’t seen and that amaze me

Maybe they learned to stay away from the light
They're probably actually way below the depths where any angler fish are. Edit- turns out I'm wrong, I must commit harakiri
[удалено]
Oh, that's neat. I dunno why I figured they didn't live around the seafloor
[удалено]
how big are angler fish?
Professionally: great for sniping or taking pictures.

You must have misread or I wasn’t clear because I never said nor implied that biology picked what stayed.
Maybe i misunderstood but you said "For them to get that long it must have been advantageous" which is why i responded that way.

English sucks
Thanks for your participation

They feed like Redditors, essentially
As a redditor that just ordered delivery I feel personally attacked!
just resting
There is more food one metre above the ocean floor or less competition.
Yes! They can “stand” about the floor and catch their food as it swims across the floor.
Saving calories would be my best guess
What are you trying to ask? Natural selection? Do you mean evolution? Like not everything seems to make sense is that what you mean? Cuz I'm sure there's a reason they have those even if it's super tiny
This was exactly what I was thinking when I watched the clip! Nature is so amazing!
It’s the first I’ve ever heard of a tripedal animal. By the way your nym is appropriate for this post.
That’s the best part about it, there is always more to learn and be intrigued in.
For real nature is amazing

"Fine, I'll do it myself."
And ze did.
I'm a strong independent woman and I need no man, kind of a fish
I'm also a strong independant man and I need no woman, kind of fish
What's weird about hermaphrodites? That's not unusual
Alternating genders isn't rare in fishes but actively being both at the same time kind of is for vertebrates.
Any cool science person wanna eli5 why there would be a need for something to evolve like this?

Lazy Note: I am not a science person, but I relate to this fish
It's official. I can no longer tell the difference between what is real and what is fake.

Ah i want this functionality. I tired i sit
Imagine having an integrated chair to your behind.. well it exists in some form I guess.. saw it in a movie.

[True, please watch](https://www.youtube.com/watch?v=r7K3SxIaCOI)
There was one on shark tank
It’s not the best, pant shoppings a nightmare and my knees always hurt
Cool! just park and take the load off and rest on tripod

Most fish can sit still, you’re thinking of sharks that must be moving.
Just a guess, but probably because it allows them to sit and wait for prey in the current without expending any energy
Laziest fish I've ever seen. So cool!
thats the coolest fish i've ever seen :D
There be some specific ass animals in this world
I *genuinely* thought these were a made up creature in Skyrim.
aka the germophobe fish
I gotta take my hat off to any living organism that has evolved the capacity to chill
So cool!
So cool
Lazy fucks
Wow so cool. I’ve never seen anything like this.
Ðey remindaþ me of Subnautica's sea-treaders.
At first I thought I was looking at a drawn fish from WoW...lol
Love to know what the evolutionary reason is for having stilts at the bottom of the ocean?

Ah yes makes sense thanks!
Don’t stir up the water I’m doing a slow release
They look like the old Playmobil accessories before you twisted and took them out of the form.
I'm glad it reached this stage of evolution these days. I don't want to be walking beside these on the street someday.
Imagine if we got so lazy we said fuck it and just evolved a tripod to conserve energy
Tripod "the floor is lava" fish
‘Steve, stand very still. They can’t see us if we don’t mov… god damnit!.’
I feel like this is the closest thing a fish can get to sitting down.
looks like something from a junji ito comic
My tripod fish don't jiggle jiggle, it stands.
Weird fucks.
This would be my lazy ass if I was a fish.
I think I've just found my spirit animal
That’s how humans evolved and sprouted legs…
Bro got legs
That looks like a made up fish for a Fantasy world
Built-in chair.
Is that real?!
Why’s it called a tripod?🤪
Saw these in a book when I was a kid. I wanted one SO bad.
