I took this photo as part of my story on hummingbird biomechanics. The squishy, forked tongue acts like a micro-pump when it touches liquid, allowing the hummingbird to lick a flower up to 15 times per second. This was taken in Chris Clark's lab at UC Riverside, and based on research done by Alejandro Rico-Guevara and Kristiina Hurme. In the last decade, Nat Geo photographers took 21,613,329 images in the quest to document the world and everything in it. This image was chosen as one of the 15 images that resonated most with us.」12月29日 9時30分
