Scientists discovered a millipede that has 414 legs, 200 poison glands, and 4 penises! What other animals have more than one penis and why?
A relative shift in cloacal location repositions external genitalia in amniote evolution
“The move of vertebrates to a terrestrial lifestyle required major adaptations in their locomotory apparatus and reproductive organs. While the fin-to-limb transition has received considerable attention, little is known about the developmental and evolutionary origins of external genitalia.”
Here’s why some animals have two penises
“Scientists in the US have solved one of the biggest mysteries in evolutionary biology – how the penis develops, and why animals such as snakes and lizards have two, while mammals and birds are stuck with one.”
“It’s not a question a lot of scientists ponder out loud, but it’s key to much of life on Earth: Exactly how does the penis form? Today, two teams of researchers report having solved one part of this mystery, pinpointing how the organ gets its start in snake, lizard, mouse, and chick embryos.”
