Exotic ‘Twilight Zone’ Reef Is Brimming With Unique Forms of Life

We tend to think of coral reefs as luminous, undersea jungles that pepper the shallow, scuba-friendly tropics. But deeper down, in a region about as bright as Pluto on a sunny day, there lie vast reef ecosystems unknown to science.

Richard Pyle, a zoologist at the Bishop Museum, has spent the last twenty years surveying one of these landscapes—the so-called “twilight zone” coral beds that encircle the Hawaiian archipelago at depths of 30 to 150 meters (100 to 500 feet), where light is perpetually dim. His extensive findings aresummarized today in the journal Peer J, in the most comprehensive study of low-light coral reefs ever conducted. And they reveal a world far stranger and more complex than we imagined.
