DIVE DEEPER

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...
Methane gas, trapped deep within the Earth's crust, can slowly leak from cracks in the seafloor known as methane seeps. While we would never consider methane as food, in the deep sea where there is...
Come along as scientist Dr. Brendan Roark narrates a submersible dive to collect and study deep-sea corals. Roark studies deep-sea corals to understand the history of the ocean and past ocean...

Dive through the zones of the ocean to the deep ocean bottom, where many strange species live, and there are many yet to be discovered. Explore them in the Deep Ocean Exploration section.
Dr. Edie Widder spoke at the National Museum of Natural History as a part of the Changing Tides Lecture Series and discussed her work on underwater light: light chemically produced by animals through...
Take a look at strange deep-sea creatures rarely seen before. Scientists and students from 16 nations photographed these creatures on an expedition to the Mid-Atlantic Ridge. Take the dive and...
CREDIT: Chris Kenaley The Mystery Develops Flash forward to 1956, when scientists described another new kind of fish. It was named the tapetail because of its long, streamer-like tail. It also had a...
Discovered in 2004 and named in 2009, this Gersemia juliepackardae coral has been spotted and collected at several seamounts in the northeast Pacific Ocean at depths of 500-2,000 m (1,640-6,562 ft)...
It took a while for scientists to identify what made this spiral track. At first they had only glimpses of the track-maker from fuzzy photographs. Finally, after studying a specimen and clearer...
Did you know that 80 percent of the volcanic eruptions on Earth take place underwater? These underwater eruptions occur regularly, forming new landmasses and providing a living environment for deep-...
These deep-sea photographs show a variety of broad-collared enteropneusts or acorn worms . These wormlike animals make spiral tracks on the sea floor. All the species shown here are new to science,...
These deep-sea corals at the Madison-Swanson Marine Reserve in the Gulf of Mexico are protected, along with the marine life they harbor. Learn more about deep-sea corals and marine protected areas in...
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,...

Sunset? Time to glow! A biological clock triggers bioluminescence in the dinoflagellate Pyrocystis fusiformis . At dusk, cells produce the chemicals responsible for its light. Hear from marine...
When a whale dies, the story has just begun. The massive carcass sinks to the seafloor, where it provides food for a deep sea ecosystem on the otherwise mostly barren seafloor. There are several...
