Distance and Size Estimation in the Tiger Beetle Larva: Behavioral, Morphological, and Electrophysiological Approaches
- 147 Downloads
Estimation of the size and distance of an object is one of the important visual functions for a wide variety of animals. How do animals visually measure distance and size? The size of the retinal image of a given object changes as a function of both distance and its absolute size. Since higher animals can learn the absolute size of many objects in their visual worlds, they can estimate the distance to a particular object by its apparent angular size from knowledge of its absolute size gained by memory. Of course, humans can also estimate an object’s distance by binocular disparity.
