A female leopard shark in an aquarium in Australia has done something not unprecedented but always fascinating: She's delivered three babies without the aid of a Mr. Shark.
The scene of the "virgin births" was the Reef HQ Great Barrier Reef Aquarium, in Queensland. It's the first time the shark, named Leonie, has reproduced without a father, having been separated in 2013 from her last mate.

Some animals, such as insects, lizards, other species of fish and snakes, can reproduce without a mate through a process called parthenogenesis, in which embryos develop without fertilization.
All told this year, Leonie has laid 41 eggs, according to the aquarium's video update on the births (below) .

Leonie's three children are all females (Cleo, CC and Gemini).
"During a virgin birth the mother can only produce females because she can only pass on her genetic information," Laura Coulton, a scientist with the aquarium, told the Daily Mail.
However, she added, the babies are not genetic replicas, as their genes have been "reshuffled" a bit.
