New research reveals what makes a frog's tongue

This is Scientific American. I'm Lydia Chain.

"Literally in the blink of an eye, the insect is gone

Noel and her colleagues studied frog tongues

to understand how frogs slurp up their prey.

First, Noel studied the physical properties of the tongue.

Prey sinks deep into the tongue's surface,

like a bungee cord so the frog can reel in

Frog tongues are like spit-saturated sponges

"So I scraped about 17 or 18 frog tongues."

Those spit samples revealed frog saliva is

The saliva starts out viscous and sticky,

"And it is able to penetrate all the tiny cracks

After that impact, the spit thickens again,

in order to loosen the spit enough to swallow its morsel.

that lets frogs scoop up prey in an instant.

Of course not even super spit can help the frog

For Scientific American, I'm Lydia Chain.
