Very cool that some creatures have discovered ways to apply fluorescence.
Sounds like an open field of research is to start checking every living thing with UV light and see which ones fluoresce and to try and figure out how and why.
Thanks for the interesting post. Resteemed
Indeed that is where I would be interested to see things go next. Then take that data and see what uses we believe the ornamentation in each case have and see if a broader evolutionary pattern exists, or if it's all related to mating.
