It may be the last place you’d expect to find corals—up to 6,000 m (20,000 ft) below the ocean’s surface, where the water is...
Imagine eating an entire fish bigger than you—bones and all! At only 25 cm long, the black swallower often eats fish much larger than itself with the help of an expanding stomach. Sometimes the meal...
The yellow bioluminescent ring on this female octopus ( Bolitaena pygmaea ) may attract mates. Bioluminescence is an important adaptation that helps many deep sea animals survive in their dark world...
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...
These corals from the Smithsonian collections are Stephanocyathus (A.) spiniger , a solitary, deep-water stony coral species. Around 74% of all deep-water corals are solitary, living as individual...

Marine biologists discover a whalefish -- an incredibly rare deep-sea fish -- swimming in the ocean in this video. Because it is so dark where they live, females have well-developed sensory pores,...
Unlike the shallow tropical coral reef pictured on the top, the deep-sea Oculina reef at bottom does not require sunlight. Learn more in the article " Coral Gardens of the Deep Sea ."

The robotic arm of the Jason, a Remotely Operated Vehicle (ROV), collects several stalks of black coral from the seafloor. Read more about how underwater vehicles help ocean scientists study deep-sea...
There can be catastrophic results when a large amount of oil is spilled into the ocean—as when the Deepwater Horizon rig exploded and spewed oil into the Gulf of Mexico in 2010. But did you know that...
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...
Corals are not only found in shallow tropical waters, but in cold, dark, deep areas of the sea. Amazing coral forests are found at depths of 60-3,050 meters (200-10,00 feet). They support an...
