There are 36 species of rattlesnakes and between 65 and 70 subspecies, native to North and South America. Rattlesnakes are cause for the highest rates of snakebite injuries in North America. However, rattlesnakes rarely bite unless provoked or threatened.

Although rattlesnake bites are venomous, they do not often result in death. Rattlesnakes come in a range of colors; from shades of brown, grey and black, to tones of yellow, cream, rust, olive, and even light pink.

Each has its own unique pattern. Some have diamond shapes on their scales, others have bands or blotches, and some species have no pattern at all.

What do rattlesnakes eat is largely determined by the range of habitats they can be found in. They are very adept at hunting and are easily able to ambush their prey due to their color and pattern, which camouflages very well with their environment.

Unlike most snakes, rattlesnakes are ovoviviparous, which means that they give birth to live young. However, they are not like mammals, as rattlesnake babies are formed inside eggs, which hatch inside of the female, so the young emerge already free from their shell.

Newborn rattlesnakes are born with the ability to hunt. After about a week after birth, they shed their first skin and begin to search for small prey. What do rattlesnakes eat is similar for both juveniles and small adult species, as they mostly feed on little lizards and small rodents.
