Visually guided head movement in the African chameleon

Vision Res. 1985;25(7):935-42. doi: 10.1016/0042-6989(85)90204-4.

Abstract

Visually guided head movement was studied in the African chameleon. Within certain ranges of frequencies and amplitudes, the chameleons followed horizontal, sinusoidal cricket (bait) movement with sinusoidal head movement and no apparent eye movement. Although head movement lagged behind bait movement, the chameleons used head amplitudes that minimized the motion of the bait relative to the head.
