Study: Female sharks fertilize own eggs – Yahoo News

Lesbian hammerhead shark moms! Well, all right, maybe not lesbian. But there is a baby hammerhead with three moms and no dad in a Nebraska zoo, apparently conceived parthenogenetically.

In an interesting bout of synchronicity, this comes just as I’ve lately been rediscovering Shriekback, a band one of my housemates back in the 80s used to love and play incessantly. And my two favourite songs of theirs are “Hammerheads” — relevance rather obvious! — and “Nemesis”, which rhymes the title word with, yes, “parthenogenesis”.
