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.

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"MarkSturtevant wrote:This reminds me that UV lights can generate flourescent colors in some arthropods.
