This lanternfish ( Diaphus sp .), found in the Red Sea, has light-producing photophores along its ventral surface (belly), and a nasal light organ that acts like a headlight. Hear scientists tell...
Discover some amazing corals in this footage that shows and identifies a range of deep-sea coral species from the Juan de Fuca Canyon off the Olympic coast and the Davidson Seamount, an underwater...
It is a well-known fact that for animals living in the deep sea, food can be scarce. The food that is around usually rains down from above as dead animals and organic particles from plankton living...
Oceanographers divide the ocean into three broad zones. Together, they could hide 20 Washington Monuments stacked on top of each other. Each zone has a different mix of species adapted to its light...
Like a cake, the ocean has different layers—each with its own characteristics. (No icing, though.) The surface layer receives the most sunlight, allowing photosynthetic organisms like phytoplankton...

Thousands of seamounts—most of them undersea volcanoes—tower above the muddy seafloor. They provide something hard to come by in the deep ocean : a solid surface to cling to. This photo gallery shows...
In the icy waters of the Arctic , a deep-water larvacean (aka “sea tadpole” because it looks like a tadpole) drifts through the water in its 'house.' This house is made of protein and creates almost...
I still haven’t gotten beyond the ‘gee whiz’ factor of studying communities of animals in deep-sea coral habitats. Climbing over undersea mountains and along the steep cliffs of submarine canyons...
Deep-sea species like this dragonfish ( Bathophilus indicus ) live in cold, dark waters and may go weeks or months between meals. When food is found, the fish uses its impressive teeth—including some...
