The Komodo dragon uses its tongue to taste and smell like many other reptiles. They have a special part of the body called the Jacobson's organ for smelling. With the help of a good wind, they can smell dead animals from 4–9.5 kilometres (2.5–6 mi) away. The Komodo dragon's nostrils are not very useful for smelling, because it does not have a diaphragm. It only has a few taste buds in the back of its throat. Its scales have special connections to nerves that give the lizard a sense of touch. The scales around its ears, lips, chin, and bottoms of the feet may have three or more of these connections.
