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.1 V. harveyi may be a more common cause of luminous vibriosis in commercially farmed marine invertebrates such as in penaeid shrimps (prawns)2.
Quorum sensing
Groups of V. harveryi bacteria communicate via quorum sensing to coordinate the production of light via bioluminescense.3 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.45
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.
