A baby swell shark named Yoko has been born in a Louisiana aquarium with only female sharks present for over three years. This unusual event has raised questions about the possibility of parthenogenesis, a form of asexual reproduction. The egg was unnoticed for months before hatching, and Yoko's paternity is expected to be clarified through DNA analysis. If confirmed as parthenogenesis, it would mark a significant finding in shark reproduction, adding Yoko to a list of known parthenogenetic animals, stemming from unique evolutionary adaptability.
A baby swell shark born in a Louisiana aquarium comprised only of females has raised the possibility that this species may reproduce asexually through parthenogenesis.
This situation is incredible and shows the resilience of this species, said curator Greg Barrick, expressing excitement about confirming Yoko's reproductive method.
