The Komodo dragon is able to see in colour, but has poor visual discrimination of stationary objects. The Komodo dragon uses its tongue to detect, taste , and smell stimuli , as with many other reptiles. The Komodo dragon prefers hot and dry places, savanna and tropical forest at low elevations. For shelter, the Komodo dragon digs holes that can measure from 1-3 meters in wide with its powerful forelimbs and claws.
