A barnacle that attaches itself to female crabs and convinces said crab that it is her eggs so that the crab will take care of it, and help it distribute its own eggs. But it sometimes attaches itself to male crabs.In that case, it releases hormones that convince the male crab that it is female, sometimes to the point that the gonads actually flip sex.
Well, that’s horrifying.
But it’s also… well, huh. Hormones being fed into an organism without the organisms knowledge or consent, causing it confusion about its gender. one wonders if there might be some sort of analogies that can be drawn. Such as to chemicals in the water and food supply… birth control pills flushed down the toilet, entering the sewage treatment systems, *not* getting processed out and then dumped into the water supply. “Forever chemicals” added to plastic drinking bottles that mimic gendered human sex hormones, and which are now detectable in *rain.*
