Most humans (especially males) are so preoccupied with debating the ideal penis size that they can't even discuss the shape of the limb of other animals (yes, deep down you're just an animal too).

It turns out that nature is extremely amazing in the sexual conception of some species. So much so that studying the genitalia of certain pets can be extremely useful for many scientific applications! Warning: The videos and images in this article can be quite disturbing. Think carefully before reading on.

Check out 7 different (and even scary) images of the reproductive organs of some species:

1. Hard-tailed Duck

Despite its name, it is the penis of this Argentine duck that impresses with its size: it can exceed 40 centimeters! Proportionally, it is the largest member among vertebrate animals. And it's even more curious among birds, which usually don't have penises. Corkscrew shaped, scientists believe that natural selection made females of the species prefer the "gifted", causing the species to develop this gigantic limb.

2. Alligator

The alligator, a "cousin" American alligator species, has a permanently erect penis that is hidden within its own body. When it comes time to mate, the member leaves the cloaca ready for action. Check out the video below:

3. Argonaut

This type of octopus enters the list of the weirdest genitals because of its detachment from its own limb. Literally! The animal is so “give it a damn” with its penis that lets it out of its body in search of females of the species. So much so that the first time scientists found an argonaut limb "swimming" in the sea they thought it was some kind of parasitic worm.

4. Python

It's time to rethink dubbing your penis "snake." In fact, they have such a bizarre member that you would hardly want to make such a comparison. Usually, these animals have the so-called hemipenis, which is a reproductive organ with two heads. Only one of them is used during intercourse, and the other may take action at a later time.

5. Bean Worm

Here is a beautiful representative who is responsible for the Maria da Penha Law in the animal world: the bean weevil penis has several sharp points that leave traumatic scars on the vagina of this beetle species. Scientists believe that males do this to prevent females from mating again or to ensure that they actually have their "offspring" and do not need to breed again.

6. Marine flatworm

There is a kind of marine flatworm that wages a true penile battle on the seabed! In the photo below, two individuals are struggling to see who will be the "female" of the species. Flatworms are hermaphrodite beings, that is, they have both sexes. However, it is much “easier” to produce sperm than eggs, so the need to fertilize a “mate” rather than oneself. Curious, huh?

7. Echidna

If you found it strange that the snake penis has two heads, you will be even more frightened by the member of this egg-laying mammal: it's four ends, which work in pairs. Scientists are not yet able to fully explain this whole amount of penile ramifications, but the Echidnas fit only two of them during the sexual act.

It's too much head for little animal, don't you think?

If you are still envying the 40 cm of the Argentine duck's penis, it's time to do a self-analysis: rest assured that your pee will be fully functional for what it proposes. And the question of size is just a thing of your head, you need to know how to use the instrument you have! Write down some tips and be happy!
