62-Year-Old Ball Python Shocks with Unexpected Egg Laying
12 Oct
Summary
- 62-year-old ball python lays viable eggs
- Last mated with a male over 15 years ago
- Potential case of parthenogenesis, rare asexual reproduction

On October 12th, 2025, a remarkable event unfolded at the Saint Louis Zoo. A 62-year-old ball python, defying expectations, laid viable eggs. This is particularly noteworthy as the snake had not been with a male for over 15 years.
Scientists are now investigating the possibility that this is a case of parthenogenesis, a rare form of asexual reproduction in reptiles. This phenomenon, where a female snake can produce offspring without the involvement of a male, is extremely uncommon and offers valuable insights into reptile biology.
The snake's advanced age and continued fertility have left researchers fascinated. This discovery could lead to a better understanding of the longevity and reproductive capabilities of these remarkable creatures. As the investigation continues, the Saint Louis Zoo's unexpected find is sure to captivate the scientific community and the public alike.
