A leopard shark in a Townsville aquarium has shocked scientists by being the first in the world to give birth without a male, after previously mating in the typical way.

The shark hatched three eggs in April last year, despite being isolated from male sharks since 2013. 

The breakthrough research, now published in Scientific Reports, confirms no male sperm was involved in the eggs' fertilisation. The process is called parthenogenesis, meaning virgin creation in Greek.
