Why Do Oceans Sometimes Glow in the Dark?

The ocean can glow because some tiny sea creatures have a special ability to make light. Imagine if you had little glowing jellyfish inside your body, every time they moved or got scared, your whole body would shine! Some plankton in the water do this when something touches them or when they swim. It's like the ocean is wearing a glittery dress at night.
