The Light-Organ Symbiosis of Vibrio fischeri and the Hawaiian squid, Euprymna scolopes

Joerg Graf, University of Connecticut

This informational web page features the luminescent bacteria that live within the light organs of the bobtailed squid and the Hawaiian squid. The page includes a discussion of how symbionts and host influence each others development, bacterial genes required to successfully colonize the squid, the "venting" microenvironment, evidence for oxidative stress occurring inside the light organ, initiation of symbiosis, and the investigators who study the V. fischeri-E. scolopes symbiosis. It also features color images and links to selected reviews and research publications.
