Squid fishermen use really bright lights (which can be seen from space!) to attract squid to the surface at night, but a lot of squid also naturally avoid surface waters that are lit during the day (by the sun) and at night (by full moon). As far as squid are concerned, what is the difference between the bright artificial lights and diffuse light that naturally occurs?
