In addition, snakes may deliberately choose ambush sites that facilitate infrared detection of prey. [16] [17] It was previously assumed that the organ evolved specifically for prey capture. [11] However, recent evidence suggests that the pit organ is also used for thermoregulation.

The snake detection theory, [1] [2] [3] also sometimes called the snake detection hypothesis, suggests that snakes have contributed to the evolution of primates' visual system. According to the theory, predatory pressure from snakes has selected individuals who are better able to recognize them, improving their survival chances and therefore ...

Generally, vision is best in tree-dwelling snakes and weakest in burrowing snakes. Some have binocular vision, where both eyes are capable of focusing on the same point, an example of this being the Asian vine snake. Most snakes focus by moving the lens back and forth in relation to the retina. Diurnal snakes have round pupils and many ...
