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?

Just post some stuff and don't spam.

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)

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
