It depends on the species. Diamondback rattlesnakes, the largest of the rattlers, have young that are 10 to 12 inches in length when born.
Rattlesnakes breed once every 2-3 years.
2 to 6 hours
Depending on the actual species - 20-25 years.
Some species of snake lay eggs, but not the rattlesnake, they give birth to live young.
Rattlesnakes do not take care of the young, they are fully capable of looking after them selves at birth.
15 to 20 years
As long as they stay babies is how long they stay babies.
Rattlesnakes do not actually want to bite you. They rattle the tip of their tail as a warning to stay away, and if the enemy does not leave, it will bite. Rattlesnakes with babies are especially aggressive, so they may bite right away.
Rattlesnakes are called rattlesnakes in the desert and elsewhere.
A rattlesnake may produce a dozen or more offspring at a time. They only breed every 2 to 3 years, however.
Rattlesnakes do not have eyelashes.
There are no rattlesnakes in Scotland.
