Cuttlefish that is.
Sitting with the family watching Nova (science show here in the US) about the cuttlefish. Yes, my life IS that glamorous and exciting! Anyway, they get to the discussion of mating and how a single female cuttlefish will draw about ten or more large males that hover over her and basically fight with each other in order to mate with her. But(!!!) here is where it gets interesting.
There is a smaller male that changes its exterior appearance to that of a female. “She” glides past the typical male idiots fighting with each other, sidles up to the female, and l’amour! The best part is that the scientists have tested cuttlefish DNA and determined that the females mate more often with the crossdressers and seem to actually prefer them! Hypothesis is that female cuttlefish figure the crossdressing males are way smarter and trickier than the larger idiots.
I’ve been saying that for years. . .
