How Many Teeth Do Snails Have? The radula houses the snail’s ‘teeth’. Snails usually have between 10 and 15,000 teeth, though some may have up to 25,000. They’re generally organized in rows of about ...

There's the fact that human teeth are sensitive. Plus, the structure that Haridy had found in Anatolepis (the now-arthropod) was for sensing.

But the new scans she conducted enabled a 3D look at the fossils, revealing their internal anatomy. "This shows us that 'teeth' can also be sensory even when they're not in the mouth," Haridy said.

“This shows us that ‘teeth’ can also be sensory even when they’re not in the mouth,” said study co-author Yara Haridy, a paleontologist at the University of Chicago.
