Facultative parthenogenesis, which is what is being seen in these common smooth-hound sharks, allows an animal to reproduce both sexually and asexually, depending on the circumstances.

In a surprising development in marine biology, recurrent parthenogenesis has been documented for the first time in the shark Mustelus mustelus, also known as the common smooth-hound. This discovery, ...

More animals can occasionally reproduce asexually through a process called parthenogenesis than scientists realized.

For most animals, sex is an egg-meets-sperm affair that requires both a male and a female. Aptly, this is called sexual reproduction. However, some species have the remarkable ability to reproduce ...

A North Carolina stingray's surprise pregnancy is most likely the product of parthenogenesis. National Geographic's Christine Dell'Amore shared the details of how this works.
