I never knew the sex life of ducks could be so interesting. To summarize:
- Male ducks have really long ones.
- Male ducks have really twisty ones.
- Female ducks have really twisty ones too, with dead ends.
- The handedness of the thread can be different in male and female ducks.
They’ve yet to find out how the two fit together. Stick them in an MRI machine, perhaps?
This is going to be a contender for this year’s Ignobel Prize, for sure!
