Bioluminescence is a trait found in a number of marine bacteria.  Some strains use their ability to emit light to form symbiotic relationships.  A number of deep sea fish and squids have specialised <em>light organs</em> which harbour populations of bacteria that help their hosts by emitting light.  One such example is the partnership between the Hawaiian Bobtail squid <em>(Euprymna scolopes)</em> and the bacterium <em>Vibrio fischeri</em>. At night squid hunt high in the water column, attacking their prey from above.  Vibrio Fischeri is usually found in symbiosis with the Hawaiian Bobtail Squid. The squid uses the light produced by its symbionts to hide the shadow it casts when hunting in top waters in clear moonlit nights. An elaborate light sensing and shutter system adjusts the light output to the light that falls on the squid's back. Other bioluminescent bacterial species can differ markedly in their lifestyles. Vibrio Harveyi is a free living marine bacterium, while Xenorhabdus luminescens is a symbiont of terrestrial nematodes.

To complement 'Project Firefly', we wanted to use lux operons for the following two purposes:
To complement 'Project Firefly', we wanted to use lux operons for the following two purposes:
* Emission of blue light to complete our spectrum of emission wavelengths.
