The facial pit actually visualizes thermal radiation using the same optical principles as a pinhole camera, wherein the location of a source of thermal radiation is determined by the location of the radiation on the membrane of the heat pit. However, studies that have visualized the thermal images seen by the facial pit using computer analysis ...
Like all pit vipers, rattlesnakes have two organs that can sense radiation; their eyes and a set of heat-sensing "pits" on their faces that enable them to locate prey and move towards it, based on the prey's thermal radiation signature. These pits have a relatively short effective range of about 1 ft (0.30 m) but give the rattlesnake a distinct ...
Experiments have shown, when deprived of their senses of sight and smell, these snakes can strike accurately at moving objects less than 0.2 °C (0.36 °F) warmer than the background. [6] The paired pit organs provide the snake with thermal rangefinder capabilities. [7]
Venomous snakes have been said to have oblong pupils that look like a slit in the center of the eye, whereas nonvenomous snakes will have a round pupil. In fact, according to a document on the NC ...
Why did it have to be snakes?” The reptile, christened Tachymenoides harrisonfordi, measures 16 inches long and is a pale yellowish-brown colour with black spots and a black belly.
However, the research goes on to note that "to date, only a handful of snakes have been observed to hunt in groups, and coordination among them — or among any other group-hunting reptiles ...
Arboreal snakes generally have better vision than burrowing species. Some snakes, such as the Asian vine snake, possess binocular vision, enabling both eyes to focus on the same point. Most snakes focus by moving the lens back and forth relative to the retina. Diurnal snakes typically have round pupils, while many nocturnal species have slit ...
