Reproduction of Eastern Diamondback Rattlesnake
The Eastern Diamondback Rattlesnake is an ovoviviparous snake variety. The gestation period lasts for six or seven months and the female snake offers birth to young ones between July and early October that ranges from 7 to 21 at a time. The newborn snakes will come out with the body length between 12 inches (30 cm) and 14 inches (35 cm) and are similar in look to the adults. However, the juvenile Eastern Diamondback Rattlesnakes live with their mother for some hours only earlier than they start out on their own to pursue and discover cover, thus the death rate is extremely high.
The average lifespan of the Eastern Diamondback Rattlesnake ranges from 10 years to 20 years.
