The CDC estimates that 7,000 to 8,000 people per year receive venomous snake bites in the United States. Five of those people die and the number of deaths would be much higher if people did not seek medical care.
Snakes are found throughout the world except in Iceland, Antarctica, Ireland, New Zealand and Greenland. You can find them in tropical regions, according to Defenders of Wildlife. They flick their tongues to smell the air and usually hibernate during the winter months.
