The nascent juvenile light organ of the Hawaiian bobtail squid
A light organ (~0.5 mm across) of a Hawaiian bobtail squid, Euprymna scolopes, with different tissues are stained various colors. The two pairs of ciliated appendages, or “arms,” on the sides of the organ move Vibrio fischeri bacterial cells closer to the two sets of three pores (two seen in this image) at the base of the arms that each lead to an interior crypt. This image was taken using a confocal fluorescence microscope.

An adult Hawaiian bobtail squid
An adult female Hawaiian bobtail squid, Euprymna scolopes, with its mantle cavity exposed from the underside. Some internal organs are visible, including the two lobes of the light organ that contains bioluminescent bacteria, Vibrio fischeri. The light organ includes accessory tissues like an ink sac (black) that serves as a shutter, and a silvery reflector that directs the light out of the underside of the animal.

Pores on the surface of the Hawaiian bobtail squid light organ
The light organ (~0.5 mm across) of a juvenile Hawaiian bobtail squid, Euprymna scolopes, stained blue. The two pairs of ciliated appendages, or “arms,” on the sides of the organ move Vibrio fischeri bacterial cells closer to the two sets of three pores at the base of the arms that each lead to an interior crypt. This image was taken using a confocal fluorescence microscope.

Bonus Video: Adult Hawaiian bobtail squid burying in the sand
Each morning, the nocturnal Hawaiian bobtail squid, Euprymna scolopes, hides from predators by digging into the sand. At dusk, it leaves the sand again to hunt.
