From Humboldt Squid
In a light organ in its mantle it houses a single bacterium, Vibrio fischeri, whose light it uses for counter-illumination: it matches the moonlight coming from above and erases its own silhouette from the view of predators below.
From Hawaiian Bobtail
It is born without the bacterium. Each generation recruits it from seawater within hours, even though Vibrio fischeri makes up less than 0.1 % of the bacteria present. And if it is absent, no other bacterium will colonise the organ.
