There are two doable explanations for the thriller impregnation – the primary of which is a course of often known as ‘parthenogenesis.’
This is when eggs develop on their very own with out fertilization and create a clone of the mom.
‘I reached out to Dr. Rob Jones, the aquarium vet, and he recognized the growths as eggs,’ mentioned Ramer. ‘We haven’t any male ray. He mentioned there have been few circumstances of parthenogenesis in rays.’
The different clarification for Charlotte’s being pregnant is loopy.
