Baby shark born in tank which had just female sharks for over 10 years, pic surfaces

A baby shark was born in a tank in Acquario Cala Gonone in Italy's Sardinia despite the tank just having female sharks for over the last 10 years. The shark is believed to be the result of parthenogenesis reproduction, an asexual reproduction in which an egg can develop into an embryo without being fertilised by a sperm.
