THERE IS A TYPE OF DUCK THAT SOMETIMES LASSOS ITS POTENTIAL MATES WITH ITS PENIS
Today I found out that there is a type of duck that sometimes lassos potential mates with its penis to prevent them from getting away.
There is very little pair-bonding between the males and females in this species and the female ducks are often resistant to mating. Because of this, the courtship displays to attract females are elaborate, vigorous, and typically performed in the presence of other ducks. Researchers don’t discount the idea that sexual selection (the idea that the females prefer a longer penis) has played a role in the development of the Argentine duck’s very long member. They think it is more likely, though, to be the result of limited access to females, and intense sperm competition.
The penis itself is covered with coarse spines, while the tip is soft and brush-like. The researchers think the duck may use the brush-like tip as a sort of cleansing instrument before ejaculation to remove sperm in the female’s oviduct that was deposited by another suitor, thus increasing the mating ducks chances of paternity. Whatever the reason for the brusk-like tip, it’s clear that the term french tickler should now perhaps be renamed to the Argentine tickler!
