Maikl, this is a beautiful image.
Could you post some details about the technique, magnification and equipment?

To me it seems a microscope image with polarized light. If so it would be misplaced at the Nature forum.

okc 1-22
Is it a Lomo cine lens?

This reminds me that UV lights can generate flourescent colors in some arthropods. Best known in scorpions although this happens across a wide range of critters.
So I wonder if a UV light would produce flourescence in an annelid worm like this one since they too have a cuticle.

Here diff colors system: "he spines, or setae, on the scaled back of the sea mouse are one of its unique features. Normally, these have a deep red sheen, warning off predators, but when the light shines on them perpendicularly, they flush green and blue, a "remarkable example of photonic engineering by a living organism". This structural coloration is a defense mechanism, giving a warning signal to potential predators. The effect is produced by many hexagonal cylinders within the spines, which "perform much more efficiently than man-made optical fibres"

Remarkable picture: only surpassed by the technicalities of the worm itself.
Often reminded how poor our engineering is compared to nature honed by millennia of evolution. Thank you.
