Mating
Snapping turtles mate between April and November, and are most active in breeding during warmer months. They begin courtship by facing one another and moving their heads from side to side. Mating begins with the male mounting the female and adjusting his tail beneath the female's to allow the cloacal openings to touch. A female snapping turtle may keep viable sperm in her body for several years, so that eggs are fertilized even in years when she does not mate.
