Sorry about that- I missed the earlier parthenogenesis comment (tapatalk behaves strangely on my phone) and my biology classes failed me. Have there been cases of ball pythons doing it? I thought it was more reserved for situations (evolutionarily) where it was next-to-impossible to find a mate to breed with (all lizards eventually female, next individual may be miles away, etc.). I suppose sperm-retention would be the likelier scenario because while ball pythons are mostly stationary in their burrows, they seem common enough to be able to find viable mates. Still, that's an exceptional example!
Edit: just to clarify, when I said "eventually female" I meant due to the ability to clone themselves rather than mate with a male, not individuals changing gender within their lifetime. Though we could open this up to fishes...
