It's a little-appreciated fact that most of the animals in our ocean make light. I've spent most of my career studying this phenomenon called bioluminescence. I study it because I think understanding it is critical to understanding life in the ocean where most bioluminescence occurs.

There's a lot of animals in the open ocean - most of them that make light. And we have a pretty good idea, for most of them, why. They use it for finding food, for attracting mates, for defending against predators. But when you get down to the bottom of the ocean, that's where things get really strange.

Since my first dive in a deep-diving submersible, when I went down and turned out the lights and saw the fireworks displays, I've been a bioluminescence junky. But I would come back from those dives and try to share the experience with words, and they were totally inadequate to the task. I needed some way to share the experience directly.
