List of the largest animal penises, relative to their body size.
1. Blue whale
The blue whale boasts the largest penis on Earth. The average size of a blue whale's penis is between 2.4 and 3 meters. The exact size is difficult to determine, since the size of the erect penis of a blue whale can only be observed during copulation.
However, relative to the size of its body, the blue whale's enormous penis is fairly average. The blue whale's penis-to-body length ratio is 1:10, while the average male ratio is 1:12.
2. Ostracod Colymbosathon ecplecticos
This small ancient creature has such a large penis that even its Greek name, Colymbosathon ecplecticos, translates to “amazing swimmer with a big penis.” When archaeologists discovered fossils of this creature in 2003, they were quite surprised by its manhood.
The ratio of the length of the penis to his body was 1:5. Translated into a human, this ratio would mean the size of the penis, which would be about 38 cm. In addition, the creature had very long sperm - about 1 cm, while the size of the creature itself did not exceed 5 mm.
3. African elephant
The size of the African elephant's genitals reaches 2 meters. The ratio of penis to body size of this mammal with great dignity is 1:4 or about 45 cm in humans.
4. Deep sea squid Onykia ingens
These squids live at a depth of 3000 meters, and the size of their genital organ reaches almost the length of its body. The ratio of penis length to body units is 1:1. And one caught 38-centimeter squid was observed to have an erection in which the penis size reached 67 cm
5. Banana Slug
Banana slugs reach about 25 cm in length, with a penis to body ratio of 1:1, which means that the length of their penis is almost the same as that of a human.
6. Argentine duck
Although ducks are not known for having large penises, there is one member of the duck family whose penis size is larger than that of any vertebrate on the planet. The Argentine duck boasts a penis that is twice as long as the bird's body. The average size of the bird is about 20 cm, while the length of the penis reaches 42.5 cm.
How does this animal move with such a large organ? The thing is that the male dignity of the duck has a spiral shape. Moreover, females have a long, spiral-shaped vagina that curls in the opposite direction, helping her prevent fertilization, as males tend to forcefully copulate.
7. Sea acorn
These sessile crustaceans can change the size of their genitals depending on their environment. They have the largest penises relative to their body size, reaching a ratio of 40:1. Since they spend most of their time on the rock, they grow a long penis to increase their chances of fertilization.
