It is clear that if we are going to understand ocean ecosystems, we need to understand the part that bioluminescence plays in those ecosystems.
If we are to be good stewards of the ocean, we need to understand what lives there and how the animals interact with each other and with their environment, which means we need to be constantly seeking new and improved methods for exploration and observation.
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.
I had wanted to place the Eye-in-the-Sea at an oasis on the bottom of the ocean, in some site rich with life that was likely to be patrolled by large predators. The first time I got to test the camera at such a place was in 2004, in the north end of the Gulf of Mexico, at an amazing location called the brine pool.
The giant squid has the biggest eyes of any animal on the planet. It's a visual predator.
Finding animals that make light in the ocean is easy. Just drag a net through the water anywhere in the upper 3000 feet, and as many as 80-90% of the animals you catch can make light. The biomimetic lure that I developed imitates one of these - a common deep sea jellyfish called Atolla.
