Hey look, I've caught this big beautiful 🐟 fish! Look how beautiful it is? It's dying slowly because I'm holding it! And I made it bleed from the stomach up to the mouth in salty water! Look at me! I'm great! And it look at him squarming in painful agonizing gaps! What a wonderful world! Hurry, let's fry him before he dies.

Now all we need is one fish, two fish, and red fish

So I remember hearing that animals can't really produce blue pigment and all the blue animals are blue due to physical tricks causing light of different wavelengths to get dispersed leaving only blue. Is this the same here?

Ok I don't know anything about that, but what is blue pigment other than a particle that asorbs all colors except blue?

The guy says he only knows one butterfly that evolved blue pigment so I'm guessing this fish is also blue because of some weird trick.

Oh ok. So the pigment is not a mirror like blue?

I remember sth. About a white flower that works similar where it self is on the atomic level shaped so that it seems white, but actually isn't...

For me blue is blue, because it's blue.

In animals such as on the feathers of birds and the scales of butterflies, interference is created by a range of photonic mechanisms, including diffraction gratings, selective mirrors, photonic crystals, crystal fibres, matrices of nanochannels and proteins that can vary their configuration. Some cuts of meat also show structural coloration due to the exposure of the periodic arrangement of the muscular fibres. Many of these photonic mechanisms correspond to elaborate structures visible by electron microscopy. In the few plants that exploit structural coloration, brilliant colours are produced by structures within cells. The most brilliant blue coloration known in any living tissue is found in the marble berries of Pollia condensata, where a spiral structure of cellulose fibrils produces Bragg's law scattering of light. The bright gloss of buttercups is produced by thin-film reflection by the epidermis supplemented by yellow pigmentation, and strong diffuse scattering by a layer of starch cells immediately beneath.

Straight-up blue pigment is rare, but it does exist. Here's a list of those critters [cancer warning]: https://www.colorwithleo.com/what-animal-has-a-true-blue-pigment/

Wonder what flavor of fruit it is.

Looks like the blue fish from go fish
