    Bacterial cells aggregated above a light-organ pore of the Hawaiian bobtail squid

    7019

    The beating of cilia on the outside of the Hawaiian bobtail squid’s light organ concentrates Vibrio fischeri cells (green) present in the seawater into aggregates near the pore-containing tissue (red). From there, the bacterial cells (~2 mm) swim to the pores and migrate through a bottleneck into the interior crypts where a population of symbionts grow and remain for the life of the host. This image was taken using confocal fluorescence microscopy.
