Abstract
Scincella lateralis responds to both visual and chemical cues of prey. A visual stimulus is associated with an increased rate of tongue flicking, orientation to the prey, and attack behavior. Chemical cues are of reduced importance when the visual cue (movement) is present. However, when the visual stimulus of prey is removed, the rate of tongue flicking increases, and is significantly greater in the presence of a prey extract than to a dead prey item or a water control. When prey are non-moving or dead, chemical cures enable the lizard to distinguish potential prey from inanimate objects.
