Passage:2. Fish with Flashlights? (L)

Have you ever been sitting at home when the electricity went off? It can be pretty scary! What was the first thing you did? If you‘re like most people, you probably went searching for

a flashlight.

Have you ever heard of a fish with a flashlight? Odd as it may sound, such fish do exist. Sunlight can only penetrate the ocean to a depth of around 375 feet. Once you go below that level, the water is pitch-black. However, scientists have discovered many different fish living

in this dark, cold water that have the ability to make their own light? How do they do it?

These fish have special pouches near their eyes, tails, or fins. In each of these pouches is

a colony of thousands of bacteria. These bacteria produce certain chemicals that give off a

faint glow; the darker the surroundings, the brighter the glow appears to be. Some of these

do not want to be seen, so they simply close these shutters. This keeps the glows from being seen. At other times, the fish open these special shutters, and allow the chemical glow to light

the dark surroundings. Some scientists think that the fish use ―flashlight‖ to attract smaller

fish which they eat as food. Other scientists think that the fish use their ability to give off

light to attract a mate so they can reproduce. There may other reasons for this special

―flashlight‖ that we have not yet discovered.
