What are these like weird bumps that look like odontodes on an arthropod versus a vertebrate?

Yeah.

So I did some deep digging, read way too much about arthropods.

And found out that there are these things called sensile.

Sensile are sensory structures that are super diverse.

So like think of like a fly that lands and he's like rubbing his little legs and there's hairs all over it.

Like, you know, the movie The Fly.

Yeah.

Are those steady?

Yeah, steady.

Yeah, exactly.

So that's a type of sensile.

That's a mechanosensor one.

So it can sense the deflection as they move.

um there's chemistry ones like chemosensory ones so they touch the ground they taste the ground every time they land gross but that's what sincerely are and that's what we found on this ancient arthropod from the ladies cambridge it was sensory organs all over their bodies and so we're like oh

That's really bizarre.

So this is really intricate sensory network of like bumps and stuff on arthropods.

Fantastic.

I go and I tell Neil, my supervisor, and I'm like, hey, I think they're this.

And he's like, oh, well, that kind of makes sense that they look like teeth.
