Man, there are a lot of cool mating rituals in the animal kingdom, but it sure is hard to beat "My butt is literally glowing!"

Well played, fireflies. Well played.

It really seems like showing off.

Whales have internet. Maybe. There is a theory that humpback whale songs, which travel vast underwater distances, are encoded transferences of emotion, allowing all individuals who hear and recognise a specific song to join together into a singular, emotional and informational experience while separated physically. And that’s basically information networking! (Fact curtesy of the podcast Radio Lab, from where I get 80 percent of my brain at any time).

Thank you for a fun article about bioluminescence - I did not know that I glowed in the dark. Even a little bit.

Whale songs are utterly fascinating, and we can learn so much from them.

Have you read/heard about the "fungus internet" too? I need to write about that soon!

Expand full comment

yes!!!! Mycelium. The internet infrastructure of interconnected forests. Please write about that!

Also...solving traffic and wayfinding problems with slime mould. Slime computing. The way of the future.

It kind of gives "non fungible token" a new meaning.

We didn't have fireflies where I grew up, so I used to see them in Calvin & Hobbes cartoons from time to time and wonder what it would be like to see them in the flesh. I did see a few on trips to the US later on, but one of the most unforgettable nature moments of my life was when I saw fireflies on the east coast of Peninsular Malaysia. We were on a small boat river cruise. The night was pitch black, so we could no longer see even the banks of the river other than as darker blackness against the sky. Above, the stars were thick and bright. Then the fireflies started. They were on all sides of us, and both stars and fireflies reflected in the flat calm water of the river, so it felt like being suspended in space. Incredible.

Incredible story. I loved Calvin and Hobbes so much as a kid! There was little subversive material available in the conservative state paper I read every morning, but C&H took my little brain by storm.

Oh, and I highly recommend "An Immense World" by Ed Yong for loads of super cool amazing facts about all sorts of senses we don't usually think about, in both animals and humans

I love Ed Yong! Seconded.

I've been fascinated by fireflies, the way they glow at night. It's stunning to learn that humans have the same quality. Great to learn about this.

I love learning about bio-luminescence and it's cool how they've been finding more and more animals glow in the dark in some form.

Expand full comment

Not goats, though. :(

Maybe we just haven't discovered the way they glow yet. Don't give up hope.

They glow inside my heart! <3

Great post! And Lucifer sometimes can't shine in the dark because he's too busy playing hide and seek with the shadows. 😎

Ha! Thanks!

Algae in the ocean is incredible to witness!

It's like a moving painting, right?

@Andrew Smith ... love the idea that we are all glowing. One of my all time life highpoints was night swimming in Puerto Vallarta through bioluminescence ... it was more like dancing with light. BTW, your graphics are ... as usual ... stunning. I am making baby steps with image generation and plan on finding a course/workshop as soon as I quit dithering about the Mexico trip. Right now the dial is set to GO mid-April.

We need a glow meter ... maybe if we could measure the level of our inner luminesccence, maybe it would help us make decisions. Work on that, will you?

Joyce, have you written about that swim? If so, please feel free to link here!

No, it was LONG ago ... but it is an idea. ;-)

"We’re well known for using large-scale cooperation and the transmission of knowledge to improve things over generations." If only...

It's fascinating to learn that we humans have a hidden superpower—bioluminescence, even if it's too faint for us to see. It's incredible to think about the countless chemical reactions happening inside our cells that make this possible.

Cat eyes are creepy too! lol

Expand full comment

They sure are! I suspect it's the same sort of reflectiveness that goats have.

Expand full comment

I am fascinated by the fact that WE HUMANS GLOW! Wow!

Expand full comment

That is an interesting fact about humans to remember, thank you!

When it comes to other examples: I would love to see the glowing waves created by bioluminescent algae.

Expand full comment

Nice, Michal! The ocean has a lot more great examples of "things that glow." Maybe that's a fun place to visit in a few months.

Expand full comment

And it’s the place where you can literally take a "deep dive" if you wish :)

Expand full comment

Dad, is that you?

Expand full comment

No, and perhaps I’m missing some context, but I really enjoy this kind of playful use of language

Expand full comment

"Dad joke" - the literal "deep dive" got me! You can do dad jokes here any time, Michal!

Expand full comment

Interesting! I’ve taken note of that. In Polish, we refer to such jokes as ‘dry’ humor

Expand full comment

Generates quite a warm glow inside too!

Never knew humans possessed bioluminescence. Wow!

It's a recent learn for me as well.
