Pacu fish have teeth that look exactly like people’s. They evolved to chew nuts that fell into the water

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

I too have three rows of teeth.
Is that what my teeth suppose to look like?
I'm scared of it but also impressed it evolved to eat nuts.
When fish have nicer teeth than me.
Have you tried a freshwater diet?
What kind of people have teeth that look exactly like this? That's nuts.
Fish people
It's the "Innsmouth Look"
Hi, I'm Troy McClure
The front row ones look more similar to our teeth than an apes, so that is pretty crazy to me.

That’s fucked up.
The food that can chew you back.
What in the everloving fuck is that?? Nightmare fuel 😨
A partially eaten cooked Pacu fish.
If I went into an aquarium to find these fuckers cheesing at me I'd have to take mushrooms to cope. Thank fuck we have AI and this shits on a screen, I can sleep another day
Can we use them for transplants?
Thanks! I hate it
Nibble nibble

Ok well, I'm never swimming again.
If you wade or jump in, you'll be fine.
If your junk is dry, the fish can't get to it
If you fall in, not so much.
The most dangerous place to be is right on the shore. Either jump in or stay away. You have to commit around these nut-chompers.
You people have never watched River Monsters with Jeremy Wade and it shows.

When I wake up screaming at 2 am, this right here, this is why.
Nope.
Sounds like propaganda from Big Almond.
Is this some Midwest Big Apple?
No, that's the Big Onion.
Exactly.

Is this an example of convergent evolution?
Hey it is! Kinda. I Think.
But why are human teeth shaped like this in the front? Not so much for nuts, right?
I thought the same thing so I looked into it! The pacu fish's front teeth aren't flat like ours. They're more like our molars, which serve the same purpose of being used for crushing (so it technically still is convergent evolution)
Niiice—and thank you!!
Anytime! An opportunity to learn should always be used :)
That article you linked literally starts with
We apologize in advance for the nightmarish qualities inherent to the pacu fish
No. Nope. No way. Uh uh. I'm not scrolling down. NEVER. You hear me? I have enough nightmares as it is...
Honestly I don't blame you given the pictures of them with their teeth out
There's another marine fish that also has these kind of teeth -- look up Sheepshead fish!
I hadn't had many regrets in life, originally.
When the Japanese finally get their teeth generation DNA therapy going, everyone will be after these fish for starter scaffolds.
Are you suggesting people are evolutionarily suited to hobbling nuts?
I can eat walnut whole. The shell is fibrous, good for digestion.
Found. The pacu fish
totally what my teeth look like
