Zoologists in Germany have a previously unknown sensory faculty in elephants. It why the giant beasts' trunks so dexterous. The scientists that the whiskers at the tip of the trunk are sensitive enough to the smallest, most delicate objects. The scientists are from the Haptic Intelligence Department at the Max Planck Institute for Intelligent Systems. They the incredible sensitivity of the whiskers for the elephant's poor eyesight. The whiskers are essential for navigating, food, and social communication. The researchers say the whiskers "smart" and the elephant an added sense of intelligence.

Scientists the insights from their research will in advancing robotics and neuroscience. Study co-author Dr Andrew Schulz said: "Each whisker on elephants' trunks as a tactile sensory organ." This an elephant to pick up something as delicate as a potato chip without it. The research could help dexterity in robots. Dr Lena Kaufmann is excited about how the research could neuroscience. She said her findings " to our understanding of the tactile perception of these fascinating animals". She says the study will our understanding of "neuronal computation" — how the brain's neurons information to think, feel, and act.
