So then- What’s the roach doing? This article is unclear. For the sake of definitions:
“Bioluminescence”, in conventional usage, means any biological process which generates some light, as found in certain bacteria, insects, pelagic fishes and several zooplankton. “Bioluminescence” is not dependent on or related to fluorescence and can employ all the colors of the rainbow, but often dominated by characteristic greens.
“Fluorescence” is the enhanced, spectrum-shifted reflectivity of certain minerals and pigments. Typically mineral fluorescence appears white; But a limited range of fluorescent mineral colors are known.

The article muddies it all, suggesting this biology depends on “fluorescent light” (which itself uses novel fluorescent processes and a variety of gas-tube environments- but not reliably producing specific wavelengths) as if every glowing thing involved mysterious fluorescent minerals.

But our Science is alive! Humans continue to discover more more forms of luminance regularly. Knowing this- It’s the fun stuff! Not difficult. Let’s all keep it meaningful.
And so… where now is our perfect automated Editor?
