Northern Water Snakes Courting & Mating
Northern Water Snakes (Nerodia sipedon) are non-poisonous snakes which, as their name implies, tend to be found in the Northeast, in and around water. Females (bottom snake in photo) are heavier and longer than males (as long as five feet) and grow much faster. Since the end of May, Northern Water Snakes have been engaging in courtship rituals and mating. The male snake (top snake in photo) begins by crawling alongside a female while he rubs his body along hers. It is not unusual for more than one male to court her at the same time, with one eventually achieving copulation by twisting and coiling his tail around her body and tail as he attempts to get their cloacae aligned.
Northern Water Snakes are ovoviviparous – the female’s eggs incubate inside her body. The larger the female, the greater the number of live young she’s likely to produce in late August or September. Northern Water Snakes have between 12 and 60 young — judging from the size of the pictured female she’ll have a large litter. (Photo by Jeff Mazur)
