An Arizona Ridgenosed Rattlesnake with her newborns.

Like many snakes, including all vipers in the U.S., these rattlesnakes do not lay eggs. They give live birth to young, which stay with the mother for a period of time afterward. Once they’ve shed skin for the first time, around ten days later, they will disperse. In the meantime, these little ones spend time with their moth, following her lead on their first experiences with a big, dangerous world.
