Bat's Tongue a Showpiece of Feeding Efficiency - Presented by: The Aol. On Network

According to researchers at Brown University, this is one of nature's most perfectly evolved organs. It's the erect tongue of a bat, engorged with blood and covered with bristles to maximize its ability to collect nectar. Using a high speed camera, the researchers were able to record for the first time, a fruit bat's tongue changing shape to become the ideal tool for harvesting nectar from a plant. After filling with blood the bat's tongue increases in length by up to 50 percent.
