In a miraculous turn of events, a leopard shark has given birth to babies without a male mate inside its aquarium in Queensland, Australia. Scientists suggest that this could be a crucial step to saving this endangered species.
Researchers from the University of Queensland revealed that "Leonie" is the first recorded shark to transform from a sexual to an asexual form of reproduction.
According to University of Queensland's School of Biomedical Sciences, Christine Dudgeon, it is possible for sharks to reproduce without a male partner. However, this is the first time that a shark made a change to asexual reproduction.
Dudgeon said that Leonie already had pups with a male leopard shark until 2013 where the mating pair was separated to create more living space at the Reef HQ Aquarium in Townsville, Queensland.
Also known as zebra sharks, leopard sharks possess distinct spots that emerge during adulthood on their skin. The leopard shark is listed as an endangered species, and this major discovery can be pivotal in further conservation efforts.
Dudgeon said that Leonie surprisingly evolved and adapted to her current environment and suddenly switched since she lost her mating partner. Scientists are on a quest to find out if this switch occurs in the wild and how often does it happen and under what conditions.
The team now plans to monitor Leonie's offspring until they reach maturity and determine if sharks that are conceived asexually can have pups with a male partner.
Dudgeon noted genetic diversity would get lost after generations of asexual reproduction, in which case, it can be observed if these offspring can mate sexually.
