We are embarking on a journey to explore and understand one of our planet’s hidden frontiers—the ocean twilight zone. Our project will combine exacting science, innovative technology, and broad engagement to turn knowledge into actions that improve understanding of our planet and how to live sustainably on it.

Below the sunlit surface, there’s a realm known as the ocean's “twilight zone.” At 200 to 1000 meters below the surface, sunlight is barely a glimmer, yet flashes of bioluminescence give us a clue that these waters teem with life.
Salps
Salps are gelatinous organisms can form chains up to 130 feet long, making them the longest animal on Earth, and often form dense swarms. They feed continuously on organic matter in the water and produce dense fecal pellets that sink rapidly into the depths. Large swarms of salps may be an important part of the global carbon cycle.
Bioluminescence
In the darkness of the twilight zone, light is an important way for animals to communicate, hunt, find a mate, and avoid being eaten. The light can be almost any color, but blue travels the farthest in seawater before being absorbed. Many bioluminescent organs in fish and other organisms are filled with bacteria that the animals must acquire after birth.
Bristlemouths
The bristlemouth is a tiny fish only about 3 inches long and is believed to be the most abundant vertebrate on Earth, numbering perhaps in the hundreds of trillions or quadrillions.

Anglerfish
Anglerfish use a bioluminescent appendage to lure prey close to their mouth, but only the females. Male anglerfish are tiny and attach themselves to their mate, after which their eyes and many of their internal organs wither away.
