Two endangered sharks found in Italy have been reproducing without males. Moreover, scientists have cited facultative parthenogenesis.
Scientists in Italy have observed that endangered female Sharks kept away from males are producing asexually. Furthermore, scientists link this case to facultative parthenogenesis – the ability to produce both sexually, and asexually. Parthenogenesis is Greek for ‘virgin birth.’
Parthenogenesis is very common in animals such as crocodiles, water snakes, amphibians, and some fish. Furthermore, it was published on July 26th in the journal Scientific Report. Moreover, the chief author of the research states, “Remarkably, this finding reveals that parthenogenesis can occur annually in these sharks, alternating between two females, and conclusively excludes long-term sperm storage as a cause,
Meanwhile, it is pertinent to note that parthenogenesis is common in Sharks. Additionally, it includes white spotted bamboo sharks, zebra sharks, and swell sharks. However, recent findings of facultative parthenogenesis are the first of its kind.

Moreover, the sharks in the Italian aquarium are smooth-hound sharks, found in warm waters like the Mediterranean. However, illegal fishing has reduced their numbers. Furthermore, there is a decline in male fraternity as well.
The sharks have been producing since 2016, however the first pup died. Meanwhile, scientists gathered data on other pups born over the years. Meanwhile, scientists have found a striking resemblance in the pup’s and mother’s DNA.
New discovery of facultative parthenogenesis has taught humans a new survival mechanism in sharks, in the absence of males. Moreover, scientists hope to use the study for further research.
