It is off the charts weird.

But this particular chromosome trick isn't the only way that the human Mary might have gotten up the duff.

And besides, plants self-fertilising and grasshoppers cleaning themselves doesn't really sound like the Messiah arriving on Earth, does it?

But a zebra shark, that could be a god.

Christine Dudgeon is with the University of Queensland and she's an ichthyologist.

She studies sharks and rays.

And the leopard sharks were in Townsville at Reef HQ Aquarium.

And the shark that I want to talk about in particular is identified in the scientific papers like a secret agent 007, except she was called F1.

I'd call her Leonie.

Oh, is that her name?

Yeah.

Oh, Leonie makes her sound so much less scary, right?

So they took Leo off to another tank and Leonie is in there by her lonesome.

And what happens next?

Eggs start appearing.

Ooh.

Leonie had been a mother before.

She had had access to a male, but it had been at least two years since then.

How did she have shark chicks?

Shark kittens.
