Vipers have a line of heat sensitive pits, which detect Infra Red radiation given off by mammals. (their primary food source)
pits
The 'pit' - is a heat-sensitive organ. It allows the reptile to locate its prey - even in total darkness.
It lies in ambush, striking and envenomating the animal. Follows the dying creature then consumes it after it is dead. Rattlers are pit vipers, having a heat sensitive pit beneath the nostrils to locate warm blooded prey.
The iPod Touch has a heat sensitive screen. If you touch one with cold fingers it will not work.
Penguins are very sensitive to heat and what they digest
thermal.
I would say heat detection. Pit Vipers especially, have heat sensitive 'pits' located on their heads - which enable them to hunt prey in total darkness. Like most snakes - they feed on warm-blooded rodents such as rats and mice - these rodents hive off heat as they move - which the snake senses.
They have the same vision we have, but pit vipers, boas, and pythons have heat sensing vision that is much more sensitive than our best thermal cameras and goggles. Reptiles can also see ultra violet light, which is a spectrum other than ours.
Vipers refer to venomous snakes that are able to sense heat using two special sense organs located in front of their eyes. There are many different species of viper. Although they are very widespread globally, no vipers live in Australia.
