The fish can turn its light on and off, and can also shine it in
the direction it wishes when hunting. This light is so strong that it
can be seen underwater from 30 meters (98.43 feet) away. Indeed,
the light from a single lantern fish is sufficient to illuminate a small

room. These bacteria give off such an effective light that the organ
continues to shine even after the fish has been caught and killed. 49
Another bacterium with the same capacity provides light for

the pineapple fish (Cleidopus gloriamaris), which takes its name from
the armor-like covered scales covering its body. The bacteria find a
suitable place for themselves inside the fish's body. In finding food
and shelter for themselves that the fish provides, they emit light
that helps the fish to hunt at night and find its way. The same sort
