Valerie Clark: Frog Licking For Science On Nat Geo's AMAZING! (VIDEO)

WATCH: Researcher LICKS Frogs In The Name Of Science

Valerie Clark has an interesting way of conducting her research on frogs and salamanders -- she licks them!

This video from National Geographic shows Clark's unsavory test to decide which specimens are worthy of bringing back to the lab. Many of the amphibians secrete poisonous substances when trying to fend off predators, but rather than study every single critter, Clark employs her taste buds to find the ones most worthy of studying.

Fortunately, Clark knows which ones are safe to taste, as one wrong lick could prove extremely toxic to a human.

Watch amazing stories likes this and others, when the new show Nat Geo AMAZING! premieres on Friday, July 9th at 7pm EST on the National Geographic Channel.
