Adult rattlesnakes tend to hide rather than bite humans. Out of pure curiosity, humans often go in search of rattlesnakes. Bite records seem to show that rattlesnakes are aware that humans are too big to eat. Medical records of rattlesnake bites show that about 30% of the bites contain no venom. These are known as dry bites. Note: consider rattlesnakes bites independent events.
