Counterillumination in the Hawaiian bobtail squid, Euprymna scolopes Berry (Mollusca: Cephalopoda)
B. W. Jones, M.K. Nishiguchi 2004 Marine Biology v144, p1151-1155
This Marine Biology scholarly article presents data demonstrating that the squid Euprymna scolopes can modify the intensity of light produced by its bacterial symbiont Vibrio fischeri in the light organ as down-welling light intensity changes. Bacterial bioluminescence from the light organ is directly correlated with down-welling light intensity, suggesting that E. scolopes individuals utilize and control V. fischeri luminescence for counterillumination.
