Many of us grew up loving ducks. We would chase around ducklings or coo over how cute they were. With their silly-sounding quacks and big paddle feet, ducks are generally regarded as adorable and funny birds. They bob around our lakes and rivers, minding their own business or eating our breadcrumbs. Donald Duck is a beloved character around the world, even though he doesn’t wear pants.
However, ducks are not as cute and innocent as they first seem. There’s a dark side to these animals that many people do not know about or even suspect. Ducks are sometimes cruel and violent. They have bizarre body parts and strange behaviors that you don’t often see in other animals.
For too long, ducks have been revered as harmless and silly. For too long, the public has been ignorant of the dark tendencies of our friendly neighborhood ducks.
10. Duck Penises
Did you know that duck penises are shaped like corkscrews? They are stored in sacs under their bodies, but when a duck penis is erect, it can become up to 20 centimeters (8 in) long. That’s about a quarter of the length of the animal’s entire body. To put that in perspective, that would be like a human having a forearm-sized member. To make this even more bizarre, it’s helpful to know that 97 percent of bird species don’t even have a penis.
To make things even worse, the penises of ducks are sharp and full of backward-pointing spikes. They are specifically made to stab into the female duck painfully. The spikes dig into the female duck’s vagina like a hundred sharp hooks to prevent escape.
Also, a difference between the penis of a mammal (such as a human) and a duck is that the duck everts his penis directly into the vagina instead of getting an erection before sex. The male duck just mounts the female and then stabs her in one motion, as though using a grappling hook.
