The second part of 8 cool facts is here Everyone is super shocked The more I watch to the end, the more I doubt life Special knowledge extension ▶The chicken has no cock, the duck has a cock 97% of birds, including chickens, mate through the cloaca, and only 3% of birds have protruding external genitalia, ducks being one of them. The external genitalia of male ducks are still long and counterclockwise spiral (roosters will really be envious and jealous), while those of female ducks are in the opposite spiral. When the female duck swims in the water, this opposite spiral can prevent the male duck from acting impulsively and avoid drowning. It can be said that this is a kind of "self-protection" for the female duck. But then again, even if a penis has no penis, it can still speak for the penis, and that's enough for it to brag about for a lifetime. References [1] Zang Qiaolu, Lin Xinchun.
