How do platypuses glow?

Do platypuses glow under UV light?
As noted last month in the journal Mammalia, shining an ultraviolet light on a platypus makes the animal’s fur fluoresce with a greenish-blue tint. They’re one of the few mammals known to exhibit this trait.
How do platypus reproduce?
Platypus reproduction is nearly unique. It is one of only two mammals (the echidna is the other) that lay eggs. Females seal themselves inside one of the burrow’s chambers to lay their eggs. A mother typically produces one or two eggs and keeps them warm by holding them between her body and her tail.
How do platypuses nurse without nipples?
Like all mammals, monotreme mothers produce milk for their young. But unlike all other mammals, monotremes like the platypus have no nipples. Their milk oozes out of mammary gland ducts and collects in grooves on their skin–where the nursing babies lap it up or suck it from tufts of fur.
What turns pink under UV light?

What animals dont have nipples?
“The platypus and echidnas don’t actually have nipples,” says Feldhamer. “They have mammary glands, they secrete milk, but it just drips out onto tufts of fur.”
Can humans sweat milk?
Although every human has sweat glands, only females have glands and ducts capable of producing milk. Specifically, only women who have given birth have functioning mammary glands. The mammary glands located in the breast are responsible for producing milk for a suckling baby following childbirth.
Why do men need nipples?
A bonus of having nipples Men have the same glands, nerves, and surrounding tissues that women do. In women, the glands help lubricate the area and make the area softer for breastfeeding.

Which animal has the biggest breasts?
