Shark goes it alone

A second case of shark immaculate conception seals the case: some sharks are capable of conceiving young without needing a male.

Sharks have always been among the coolest creatures for me. First off, their evolved design: so perfect for their environment that it’s barely changed in half a billion years. Second, the sheer weirdness of shark society: in many shark species, the young have to test their mettle in the gene pool before they’re even born, fighting and eating each other inside the womb. If sharks could talk, they’d be the equivalent of Klingons or Furyans – races built on violence. And it seems that even if an enemy wiped out all the males of that species, the girls could continue regardless.

I wonder how many other species this happens in?
