"Vibrio harveyi" is a species of Gram-negative, bioluminescent, marine bacteria in the genus "Vibrio". Ecologically similar to "Vibrio fischeri", "V. harveryi" has both a free-living form, as well a symbiotic relationship with other marine organisms.

Quorum sensing

Groups of "V. harveryi" bacteria communicate via quorum sensing to coordinate the production of light via bioluminescense. [cite journal |author=Greer LF, Szalay AA |title=Imaging of light emission from the expression of luciferases in living cells and organisms: a review |journal=Luminescence : the journal of biological and chemical luminescence |volume=17 |issue=1 |pages=43–74 |year=2002 |pmid=11816060 |doi=10.1002/bio.676 |url=http://dx.doi.org/10.1002/bio.676] While similar to "V. fisheri" in many ways, the quorum sensing-based signalling system in "V. harveyi" appears to be significantly more diverse and complex.cite journal | author = Milton D | title = Quorum sensing in vibrios: complexity for diversification | journal = Int J Med Microbiol | volume = 296 | issue = 2-3 | pages = 61–71 | year = 2006 | pmid = 16487746 | doi = 10.1016/j.ijmm.2006.01.044] cite journal | author = Meighen E | title = Autoinduction of light emission in different species of bioluminescent bacteria | journal = Luminescence | volume = 14 | issue = 1 | pages = 3–9 | year = 1999 | pmid = 10398554 | doi = 10.1002/(SICI)1522-7243(199901/02)14:1<3::AID-BIO507>3.0.CO;2-4]

Based on samples taken by ocean-going ships, "V. harveyi" is thought to be the cause of the milky seas effect, in which, during the night, a uniform white glow is emitted from the seawater. Some glows can cover nearly 6,000 square miles.
