Mountain gorillas were saved from extinction thanks to the incredible and unorthodox Dian Fossey. | National Geographic TV

Are gorillas are picky eaters? Nope. We might instead use the term "selective" eaters. 🌱 Gorillas can create the perfect bite of a plant by cleaning off dirt and debris and then wrapping and compacting the leaves before putting them in their mouths! Manipulation techniques can vary for each food they eat. In this video, watch Taraja eat Gallium - one of mountain gorillas' favorite foods! 📹 Eric Ndayishimiye | Dian Fossey Gorilla Fund

Field research has changed a lot since the time of Dian Fossey. Today, we still collect much of the same data, which means we now have information on five generations of gorillas! However, we also now have technology to help us answer more advanced and in-depth questions related to physiology, genetics, and nutrition. | Dian Fossey Gorilla Fund
