Snakes feed on small animals, such as rats, mice, frogs, lizards, birds, insects, other snakes, etc.
Snakes usually eat two to three times their own weight.
Snakes rely on their senses of sight, smell, or thermo-sensitivity to locate prey.
Although snakes do not have any external ears, they “hear” ground vibrations with the scales on their belly and lower jaw.
Snakes can perceive prey at 10 to 15 feet. At farther distances, they only detect movement.
The vision of many snakes, like the rattlesnake, is better suited for nocturnal searching. While, some species, such as racers and garter snakes, have eyes specialized for diurnal (daytime) activity.
Snakes also have pit organs that detect infrared radiation, enabling them to form “thermal image’ of predators or prey.
