Yeah in the blacklight at the furry con

Idk if blackbody radiation counts as bioluminescence

What's concerning is figuring out the evolutionary advantage of being able to hide from predators who have eyes 1000x more sensitive to light than anything on Earth...

Uh yeah, no.

Bioluminescense relies on pigments and specific proteins involved to convert energy to a visible wavelength of light. This isn't the same as the arbitrary calories we burn to maintain homeostasis or the resulting black body radiation.

That being said, gene therapy really has come a long way and bioluminescense is pretty well understood to the point of being an undergrad lab in intro bio, so really, there is nothing stopping you from GMO'ing yourself to have glowing pigments.

Also, if you making the claim we've got zebra stripes under some conditions, please explain those conditions.

I heard that in my head as a plasmid advertisement from Bioshock.

They had a whole sets of beauty products based on radium in the 20's of the past century. They had several peculiarities such as natural luminescence and a unique pale white colour that used to shine in the darkness. I needn't to say that this was obviously one of the most dangerous and damaging things you could apply to your body. tho-radia was a body lotion and a brand that took pride in using radium in many ways, including a product for teeth. Radioactive teeth, imagine that. I hope you don't come across one of those old bottles in an antique shop, as they are still dangerous.

That's cool! Is it permanent or will I have to cut the power to a chemotherapy hospital ward to see glowy humans?

It's fairly easy to find radium dials up to these days. You can spot them based on the yellowish and crumbling look of the paint or once luminous compounds. They may not be glowing any longer but they retain their radioactivity. By contrast, tye greenish white paint on dials is usually tritium.
