 This feature is shared with the chameleons, but is otherwise unusual among lizards.Agamid lizards are generally diurnal, with good vision, and include a number of arboreal species, in addition to ground- and rock-dwellers.They generally feed on insects and other arthropods (such as spiders), although some larger species may include small reptiles or mammals, nestling birds, flowers or other vegetable matter in their diets.
