What do you do when you can reproduce without a mate? Lots of lesbian sex, I guess.

There are a lot of buzzy new articles claiming that the squid ‘impregnated’ people’s mouths, so I just thought that I would reassure you that people do not have ovaries in their mouths and that squid sperm are not compatible enough with human eggs cells to fertilize them. Just in case.

I this quote from Drs. Kelly and Orbach in this Discover Magazine article really sums harbor porpoises up well:
“An erect harbor porpoise penis goes up to its chin — or, where its chin would be, if it were not a marine mammal,” Kelly said. And their vaginas are the most complex of the four, with “a whole bunch of spiraling folds,” Orbach explained, “which just keep twisting around … a little bit like a corkscrew.”
But these journal articles are also really interesting reads (and they’re both open access, I believe).
