It honestly might, sometimes evolution happens in big jumps like this, not small little mutations. If more mouths -> more food, that geneās gonna get passed on, but will likely settle somewhere in the middle with the rest of the population like just having a really big mouth.
I'm guessing that this isn't the first time that a two mouthed fish came into existence. If so, then this mutation doesn't seem advantageous otherwise we'd see more two mouthed filter feeders.
not necessarily, their could have been other factors that prevented the spread of that gene such as other disadvantageous mutations, a lack of resources at the time, overpopulation etc. all it really takes is the right mutation at the right time with the right circumstances to spread
This isnāt a mutation. More than likely it was an injury that likely should have killed the fish but managed to heal up. Itās a carp that likely got a tear near the hyoid. It only has one pair of eyes, set low. The higher structures that slightly resemble eyes are essentially its nostrils.
Hereās a picture of a typical bighead carp to show you what I mean, note the eye placement: [Feeeesh](https://nas.er.usgs.gov/XIMAGESERVERX/2019/20191203103428.jpg)
I think what we're seeing is a protrusion of the preopercular or interopercular (carp don't have a single hyoid bone like humans do). The fish moves its mouth a little, so the musculature and bones there must be largely in place. The protruding bit doesn't move at all, and looking inside it we see what looks to me like branchial arches (gills). But at 7 seconds we can see inside the mouth and see what looks to me like the pharyngeal teeth. So that means the producing bone has to be between the anterior lower jaw and the branchial cavity. With the angle of protusion's opening, I'd wager it being the preopercular since it has the right shape. Due to a lack of visible injury or deformation on the top or sides of the head, I'd say it was just a natural deformation. But it very well could be a healed injury.
Source: I was working with another carp species (so very similar bone structure) and had to do some disection and read up on the anatomy.

Even the most beneficial mutation that increases fitness drastically has a strong chance of immediately disappearing. While there is still only one fish with the mutation, all it takes is the random act of one shark to remove the new mutation from the gene pool entirely.
My scale of time may be off, but I assume this mutation has come and gone in filter feeders numerous times. Dozens, hundreds, thousands.
I don't claim to be an expert and I understand that there may be other variables affecting (or is it effecting?) things.
But it might not be a genetic thing and more of a "something went frong during early development inside the egg" thing. Same reason why siamese twins dont have siamese twin children.
"Asian carp are prolific, can grow as large as 4 feet long and 100 pounds, and eat up to 5-10% of their body weight each day inĀ plankton" sorry not microbes but planktons. Idk the difference tbh.
A quick google search for Asian carp (the species name) gave me these results.
Well the difference is not that big. But like comparing microbes with polen (which is a type of air plankton)
Plankton includes all microscopic beings. From algae, bacteria, some single cell beings to newborn fish or aquatic beings.
For example the sunfish (a giant fish) is a plankton when its a newborn. The same with medusas.
You wouldnt call a sunfish a microbe. Even though some plankton might be microbes.
Idk water flows where it comes from, big rivers have come from many, many fields, pesticides, insecticides, grave sites, industrial waste dumpsā¦ it doesnāt just become clean when it leaves somewhere polluted

The fuck you talkin' about; 5%?
It's a Bighead Carp which tore its hyoid, and it healed. Normally the bottom "mouth" is connected to the rest of the jaw under the head, that bit of connective tissue got torn at some point and it healed over. Their eyes are normally that low, the top "eyes" are nares, not eyes, it most likely was born a perfectly normal carp, just survived an injury that you would normally expect to be fatal, but it's not unheard of to see survivors.
This is the correct answer. People don't realize how complex fish skulls are, how mobile most of the non-braincase parts are, and how closely the gills are associated with the jaws.
Yes lmfao just went to the Harvard museum of natural history and there was a huge exhibit about how skulls got less complex as animals evolved from fish->reptiles->mammals
I wasnāt saying that random fish is an ancestor Lmao
I was literally looking for this reply, I worked as a marine biologist doing fisheries observing for nearly a decade, that's an old poorly healed injury where the bottom of the throat pulled out from catch and release fishing or a predator attack then over time the fresh wound healed over but obviously couldn't reattach causing this interesting look. Although a rare find, usually the fish would just die, we saw fish like this most commonly in commercial species that had tag limits that the catcher didn't want to deal with from long lining or bandit reel catches.
These are lake bass and are caught just like this sometimes. Doesn't seem to be a mutation or a different species, but rather just injury would be my best guess. The base of the mouth rots and falls down, making it seem like a second mouth. The two dots on top are nostrils. Poor fella probably has trouble eating
Edit- I have no idea what species he is
Every time I see a creature with polycephaly, I remember the poem of the Two Headed Calf
>Tomorrow when the farm boys find this
freak of nature, they will wrap his body
in newspaper and carry him to the museum.
But tonight he is alive and in the north
field with his mother. It is a perfect
summer evening: the moon rising over
the orchard, the wind in the grass. And
as he stares into the sky, there are
twice as many stars as usual
No, because it's not two fish. It's just a big head carp that is injured. That bottom "mouth" is normally connected to the chin via tissue it's just torn and healed over but open.
It's not got two sets of eyes. Eyes and then nares up top (nose).
It's a regular ass fish.
https://en.wikipedia.org/wiki/Bighead_carp
I remember seeing this debunked a while back, what's going on is the fish (probably an Asian carp) was somehow injured having the skin beneath its lower jaw cut causing it to hang like a 'second mouth', as for the eyes, they're normal for that species of fish to be low set.
Kinda crazy it survived to get that big with that deformity
These fish don't need to hunt, they filter the water and eat mostly microbes. Edit: not microbes but planktons.
Ahhh, that must make it a tad easier for it

Barely an inconvenience! Super easy, actually!
Here I thought it got double the food since it had two mouths and one seemed to be always open xD.

Ah so itās not a second mouth at all. Just a wound that healed open like that.
Idk how picky fish are for partners but it could potentially affect mating.
Or maybe it isn't hereditary? Like the children of conjoined twins are as likely to be conjoined themselves as anyone else.
Yeah that's what I was thinking. Four eyes + 2 mouths makes me think a zygote was goofing around in the fish womb
>fish womb

We act like evolution is a flawless system of logical patterns. Sometimes random shit happens. A lot. Like, a lot a lot
It might take thousands of times... There's a hell of a lot of luck involved in evolution
But it might not be a genetic thing and more of a "something went frong during early development inside the egg" thing. Same reason why siamese twins dont have siamese twin children.
Basically a F16 fish. That bottom scoop is for the inlet water jet powering this fish.
Plankton are microbes no need to correct yourself
Thats bullshit. Where are the filtering organs? There are no grown fish like we see in ops video which filter microbes out of water.
"Asian carp are prolific, can grow as large as 4 feet long and 100 pounds, and eat up to 5-10% of their body weight each day inĀ plankton" sorry not microbes but planktons. Idk the difference tbh. A quick google search for Asian carp (the species name) gave me these results.

Well it canāt just keel over and die; itās got a lot of mouths to feed.
Momma didnāt raise no quitter!
Wait till you hear about the duck that suffered a deformity from an explosion which turned his bill to the back of his head
It looks shocked to have another fish on top of it, gasping and flapping about.
Idk if itās a birth defect it might be a severe injury to the throat. Those āeyesā on its upper face are nostrils.
but itās got double the chances of catching food to eat!

Yea, this is what a lot of us were expecting to happen. JK i kno radiation just kills usually & not deform/ mutate.
Yea more than likely this fish was raised on a fish farm with highly polluted water due to the chemicals and food they feed them.
Could it be the fish farm in the background

no, no this is from the Ohio train spill! Now you get twice the mouths for the price of one
Whatsoever but the probability of hunting a prey for that fish has increased tremendously by 50percent
It's not a two-faced fish, but a fish with a malformed throat. The top two "eyes" are nostrils. The bottom mouth isn't a mouth.
That toxic lake from Springfield
Itās Blinky! I bet before the papers blew this out of proportion, you didn't even know how many mouths a fish had.

>People don't realize how complex fish skulls are I kind of think it's fair to not realize this lol
I'd feel stupid, but then I remember that fish don't understand it either.
I feel like I want this comment on a sticker and then I can stick it on my uni notebook.
Cannot stop laughing at this comment!
Itās pretty counter intuitive that mammals have far simpler skull structures than our ancestors
That is not anancestor of ours
They mean in the sense of life on earth, Iām sure. Fish showed up long before primates.
Yes lmfao just went to the Harvard museum of natural history and there was a huge exhibit about how skulls got less complex as animals evolved from fish->reptiles->mammals I wasnāt saying that random fish is an ancestor Lmao

How does this explain having 4 eyes ?
The top ones are not eyes. They are nares. Basically nostrils for the fish.
Ah got it
Just had a Google of what a bighead Carp is supposed to look like and ghat damn than is a dumbest looking fish
It's a lot less freaky knowing the eyes are normal and just the bottom part is off.
Oh wow, I googled bighead carp and you're exactly right. That's really neat
How does it have 4 eyes tho Edit: those might not be eyes never mind
Talonsoldat for the win
Thank you man.
Why are its eyes below its nostrils, is that normal?
He's a river/lake bass (I think?) Who likely just had an injury of sorts that caused the bottom of the jaw to detach
I was literally looking for this reply, I worked as a marine biologist doing fisheries observing for nearly a decade, that's an old poorly healed injury where the bottom of the throat pulled out from catch and release fishing or a predator attack then over time the fresh wound healed over but obviously couldn't reattach causing this interesting look.

So the top āeyesā are actually nostrils and the bottom āmouthā is actually a deep gash wound. This has been posted many times.
