## Appearance and identification

The Gila monster is unmistakable, its dark body covered in bead-like scales called osteoderms patterned in pink, orange, and salmon against black. It is one of the heaviest lizards native to the United States, reaching roughly 0.5 to 0.6 m (up to 2 ft) and about 0.7 kg. The thick, sausage-shaped tail acts as a fat store, swelling after good feeding and shrinking during lean months. Its bright colouring is a warning signal, advertising to predators that the animal is venomous.
