Infrared sensing snakes use pit organs extensively to detect and target warm-blooded prey such as rodents and birds. Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [13] [14] though it does not appear that they assess prey animals based on their body temperature. [15]
The detection by predators and competing individuals of same species provides a strong evolutionary pressure. When active sensing is used, energy levels detected at the target are greater than those of the returning signal. Prey or predators evolved to eavesdrop on active sensing signals [citation needed]. For example, most flying insect preys ...
There are over 105 species of snakes in Texas, and 15 are venomous. Rattlesnakes tend to seek cool spots to avoid overheating in hot weather. They can be found under shady places like logs, rocks ...
Most research on the detection of surface waves has been done on the striped panchax, Aplocheilus lineatus. Surface wave detection by animals is the process by which animals, such as surface-feeding fish are able to sense and localize prey and other objects on the surface of a body of water by analyzing features of the ripples generated by objects' movement at the surface.

Snakes are thought to have evolved from either burrowing or aquatic lizards, perhaps during the Jurassic period, with the earliest known fossils dating to between 143 and 167 Ma ago. The diversity of modern snakes appeared during the Paleocene epoch (c. 66 to 56 Ma ago, after the Cretaceous–Paleogene extinction event).
