Breakthroughs, discoveries, and DIY tips sent every weekday. The colors and light of the deep sea are on full display in these photos from The Radiant Sea: Color and Light in the Underwater World.

Here are just a few of the photos in the new book celebrating these diverse sea creatures. Photos reprinted from The Radiant Sea: Color and Light in the Underwater World, published by Abrams.
