The chameleon, a camouflaged, slow-moving lizard, is an arboreal hunter that hides and ambushes prey. Prey and predators alike can be sighted and monitored using monocular depth perception. Also, nodal point separation allows distance to be judged with one eye, so minimal head movement is needed by the chameleon in watching its surroundings, reinforcing the chameleon strategy of inconspicuousness.
