small (20-centimetre- [8-inch-] long), squat, orange and brown Australian lizard of the Old World family Agamidae. Moloch is entirely covered with thornlike spines, the largest projecting from the snout and over each eye. The shape of its body and many of its habits are similar to those of horned lizards of North America, which are in the family Iguanidae. Both are flattened, have short tails, spines, move very little, and specialize on ants.
