How to pronounce “radula” in English

And so the radula itself is usually not preserved independently as a fossil because it's quite delicate and it probably just falls apart.

So you'll see radulas in snails, even in clams, all kinds of different mollusks.

But this discovery of that complicated radula that would have just filtered plankton out of the water has helped a new interpretation arise thinking, like, OK.

So I'll take the radula first since there's more physical evidence for it.

but it is showing you this beak out of which the radula would have unfolded.

And so looking at all of those different radulas is the main way that the paleontologists have begun to look at ammonite radulas, cephalopod radulas.

desensitized and then the snail was able to engulf it jab it with its radula and inject a potent paralytic that made sure

And then the second part of the question, the radula, is that just a mollusk trait and that's how they know that that's what the tongue looked

The chromatophores, the color changing ability, and the radula.

And so either the shell has to be physically broken and then it's sort of just luck whether you actually find the radula or whether you've destroyed it

And, in fact, all the different snail radulas are useful because snails eat in a lot of different ways.

And so if I'm remembering right, the only real radulas that are found are when they're inside a shell.

Cephalopods, squid, and octopus, and all of their cousins have these really complex tongues with a lot of teeth on them called radula.

So this tells us-- and this here is sort of a 3D reconstruction of how that might have-- this colorful part up there is the radula.

But fortunately, there are artists who work with scientists to then make reconstructions like this, which doesn't show you the radula unfortunately,
