Snake Massage

• Vibration sensitivity
The part of the body in direct contact with the ground is very sensitive to vibration; thus, a snake can sense other animals approaching by detecting faint vibrations in the air and on the ground.
• Infrared sensitivity
Pit vipers, pythons, and some boas have infrared-sensitive receptors in deep grooves between the nostril and eye, although some have labial pits on their upper lip just under the nostrils (common in pythons), which allow them to "see" the radiated heat of warm-blooded prey mammals.
