Among different reptiles , fertilization is scheduled differently and at different times, with the respect to the very time , timing and calendar events of nesting and nesting behavior and behaviors. In many , if not most species , this tends to occur , as might well be expected , just before the time periods and time periods when the actual eggs are laid. However in some species , the sperm must amazingly live on in the reproductive tract of the females, and continue thus to fertilize eggs months or even years and years after copulation activities have taken place – sometimes long ago in the past time periods.
The longest known time periods , of such deferment and deferments of fertilization activities are four years , for the diamondback terrapin of the southeastern areas of the United States – the USA. and five years in the case and cases of the tropical American cat-eye snake. The green turtle, which evidently and apparently mates only in the sea , off the nesting area and nesting beach areas, often does so only after the female has gone ashore and laid her egg and egg clutch. Since a given female makes her migration to the nesting ground only once in three or rarely in two years, it thus seems more than probable and indeed likely , that sperm itself must be stored , in a in-vivo condition , between that length of time period and periods between the nesting journeys.
