This beautiful jewel squid (Histioteuthis bonnellii) can be found swimming above the Mid-Atlantic Ridge, at depths of 500-2,000 meters (1,640-6,562 feet). The “jewels” covering the body are bioluminescent photophores. But these squids can't bargain for their lives with those jewels: they have been...

Glowing photophores are visible on a squid (Abralia veranyi) viewed from below at low light levels. We think of light as a way to see in the dark. But many species use it to help them hide. This adaptation is called counterillumination. Seen from below, an animal might stand out as a dark shape...

What does a bioluminescent creature that lives more than two miles below the surface of the ocean and a glow stick have in common? More than you think. Bioluminescence is the process by which living organisms produce their own light. Using a photographic technique called light painting, you can do...

The fish at left stands out against the lighter waters above. At right the same fish—now with bioluminescent structures on its underside lit—blends in. Many deep sea creatures have evolved this adaptation (known as counterillumination), which enables them to hide in an environment with few hiding...
