Description and significance
Vibrio fischeri is a curved rod shaped, motile, marine bioluminescent symbiotic bacterium found in the light organs of fish and squid. The bacterium is a heterotrophic facultative anaerobe that shows up as gram negative using the gram stain. V. fischeri bioluminesce only after reaching a certain population density. There has been much studies done on symbiotic relationship between a particular strain of V. fischeri and the Hawaiian bobtail squid, Euprymma scolopes. The nocturnal squid uses the bioluminescence bacteria as camouflage in a 'counterillumination' strategy, while the host provides housing and nutrients for the bacterium.
