    Male ducks respond to sexual competition by growing either an extra-long penis or a nub of flesh, a new study finds.

It suggests that penis size — in line with many traits and behaviours meant to impress or allow impregnation of the opposite sex — involves a trade-off between the potential to reproduce and to survive.
