So that's why they are so freaking sensitive!
New teeth horror just dropped.
That explains narwhals 🦄
I wonder if this was how sharks got their skin teeth
Holy crap. I'd heard of placoid scales but had no idea they were homologous to teeth. Thank you for sharing.
It's just a cool piece of information that it's impossible not to share.

It does?

Hmm. Something about it feels just wrong to me. I'm fairly sure, though, that it's a gut feeling and nothing logical. Because teeth on the outside? Because sensory organs in teeth? IDK.

Why do people do this? Not the first time I've seen someone comment the title of the post and nothing else. On Reddit, that would've been a sure sign that it was a GPT bot because that's the kind of thing those bots do occasionally when they slip up.
I think it's a reply to my incredulous "what?!"
Oooh, that actually makes sense lol. Guess I'm just slow.
Ehh. It took me a while, too, and I wrote it. Seriously though. What kind of sick evolutionary history is that? This is worse than the whole swim bladder thing. At least that doesn't make me uncomfortable.
its probably only a matter of time before that scourge arrives in our little internet hovel. most likely already happening.
We come from the sea.
