They also glow green during the day, we just can't see it because it's too bright out to see the dim glow. Only at night is it dark enough to notice the glow. There are microbes in the water that glow with bio-luminescence when they are stirred up by waves or what ever else might stir them up. The reason why they glow when stirred is because it is a defense mechanism for these microbes. When a small animal like a shrimp is eating these microbes, the microbes will light up from being stirred, which can give this small critters position away to larger predators that in turn will eat the small critter. It's a good way to call in larger predators to eat the small critters that are feeding on the microbes.

This phenomenon is called phosphorescence. It is the glow from plankton and bacteria. It is similar to the effect seen on bacon that is past its sell-by date.

Plankton and other life forms tend to come to the surface at night.
