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...

This transparent cockatoo squid (Leachia sp.), also known as a glass squid, lives in the depths of the ocean and has many adaptations to help it survive there. It retains ammonia solutions inside its body that give it a balloon-like shape and help it float. It has large eyes and pigment-filled...

What does a bioluminescent creature that lives more than 2 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...

This aptly named fish (Anoplogaster cornuta) has long, menacing fangs, but the adult fish is small, reaching only about 6 inches (17 cm) in length. It's teeth are the largest in the ocean in proportion to body size, and are so long that the fangtooth has an adaptation so that it can close its mouth...

This ctenophore (a stingless jellyfish-like animal) is native to the east coast of North and South America. In 1982, it was discovered in the Black Sea, where it was transported by ballast water. It subsequently spread to the Caspian Sea. In both places it multiplied and formed immense populations...

Under white light, this shortnose greeneye fish (Chlorophthalmus agassizi) looks unimpressive. But, in dim blue light—the type usually seen at depth—it shows its true fluorescent colors.
NOAA scientists collected this specimen during a 2004 expedition for optical studies. The scientists...

These southern elephant seals (Mirounga leonina) may look like beach bums, but when they are in the water hunting, they are anything but. Satellite tracking by tagging the animals has found that, during the 10 months they spend at sea, elephant seals spend most of their time underwater, hunting...

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...

Bioluminescence is one of the more captivating adaptations that have evolved in marine animals. It's the ability of organisms to create and emit light. Dive underwater and you may witness lightshows of red, green, and blue. Chemical reactions release energy that produces the light. Many species use...

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...
