Scientist cracks mystery of the frog’s powerful tongue. It’s called spit.

Georgia Tech researchers explain how frogs maintain their grip on their prey during the speedy attacks with their prehensile tongues. The study, published in the Journal of the Royal Society Interface, was conducted by mechanical engineering Ph.D. student Alexis Noel under the guidance of David Hu, a professor of mechanical engineering and of biology and an adjunct professor of physics.
