What is the function of the vestigial limbs of pythons (spurs) found on either side of the vent?

The spurs of pythons, which are considered vestigial limbs, play a significant role in mating behavior. During the mating process, male pythons use these spurs to stimulate the female, facilitating the courtship and breeding ritual. While these spurs are remnants of limbs and have no substantial use for locomotion or balancing as seen in other species, their function in reproduction highlights an important aspect of the biology of pythons. They serve as an adaptation that enhances mating success, which is crucial for the survival of the species.
