that cant be real 😯

@Matt85 I googled; technically it might be "biofluorescence."
On Halloween we put up UV lights to enjoy seeing parts of the kids' costumes glow (fluoresce). I don't think I've seen any flesh or hair fluoresce, but I could imaging hair dyes or treatments that might.
Researchers at a US zoo have discovered Tasmanian devils glow under ultraviolet light, weeks after the same phenomenon was discovered to occur in platypuses, bilbies and wombats.
Toledo Zoo in Ohio posted the findings on their Facebook page, and said they believed they were the first in the world to document the glowing phenomenon in Tasmanian devils.
"In the case of the Tasmanian devil, the skin around their snout, eyes, and inner ear absorbs ultraviolet light and then reemits it as blue visible light," the post read.

@ElwoodBlues ohhhh so fluoresce is reflecting outside
light and luminescence is producing inside light?

@TryingtoLava Yeah, luminescence is producing light like a firefly; fluorescence is absorbing and re-transmitting light at a longer wavelength. "Day-glo" fluorescent paint & such materials absorb blue & violet light, then emit greenish-yellow or orange light. White LEDs use the same idea, with a blue source LED and some kind of "phosphor" mix that makes a broad spectrum of warm colors.
A fluorescent light like the old straight tubes you used to see in offices everywhere is actually an ultra-violet emitting gas, and then the inside of the tube is coated with "phosphors" that absorb and re-emit several wavelengths to make white-looking light.
OK, this is getting a little deep into the weeds at this point, but I believe the spectrum at the upper right is a "warm white" fluorescent. It really doesn't take many wavelengths to fool the eye into seeing "white."

@ElwoodBlues Thanks for the clarification @TryingtoLava Thanks for Best Comment 😁
