Unidentified Comb Jelly Jan 26 2010 - 11:45am This jelly’s red color provides camouflage in the deep ocean. Red light rarely reaches those depths, and most deep-sea animals have lost the ability to see red. The long, complex tentacles of this unidentified comb jelly (Order Cydippia) have sticky cells that can snag prey, and then retract.	When Art Meets Science: Exhibition Inspired by Bioluminescence Aug 25 2011 - 12:45pm Artist Shih Chieh Huang spent a good part of 2007 exploring specimens of deep-ocean animals found in the collections of the National Museum of Natural History. He was a Smithsonian Artist Research Fellow and was investigating the unusual evolutionary adaptations that allow these creatures to live...
A Voyage of Discovery to Inner Space Aug 13 2012 - 11:05am The Mars rover Curiosity is sending images back home: glimpses of another world during a voyage of discovery. While Curiosity is clicking pictures millions of miles away, I am privileged to be taking part in my own voyage of discovery to the inner space of this planet.	Jewel Squid Dec 12 2012 - 10:33am 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...
Photographing Coral Samples Jun 7 2011 - 1:02pm After ocean scientists sort deep-sea corals according to their different types, they carefully measure and photograph the specimens. Find out how ocean scientists study deep-sea corals in our Deep-sea Corals article.	Lanternfish Nov 20 2012 - 11:24am 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 stories about encountering bioluminescent marine animals in the deep sea.
Martha Nizinski: Hooked on Deep-Sea Corals Jul 27 2011 - 11:49am Nine years ago I was invited by a colleague to join a research team investigating deep-sea coral habitats. I was asked to examine the invertebrates associated with these ecosystems. After my first look, I was hooked! I was fascinated by the sheer beauty and complexity of these deep-sea environments...	New Genus of Bamboo Coral Jun 7 2011 - 1:26pm Found 1,751 m (5,745 ft) below the surface of Hawaii’s waters in 2007, this orange bamboo coral is 1.2–1.5 m (4–5 ft) tall. It is thought to represent a new genus. Learn about more deep-sea discoveries in our Deep-sea Corals article.
Manning Seamount Deep Coral Community Dec 4 2009 - 3:33pm A variety of corals colonize the rocky surface of Manning Seamount, part of the New England Seamount Chain located in the Atlantic Ocean just off the coast of Cape Cod, Massachusetts. This photo was taken on May 15, 2004, at a depth of 1,718 meters (5,636 feet) by the remotely operated vehicle (ROV...

Explore more in the multimedia feature "Coral Gardens of the Deep Sea."	Riftia Worms: One Species at a Time Jun 14 2010 - 4:31pm In this episode of the Podcast of Life, host Ari Daniel Shapiro dives deep to discover a white worm as tall as your refrigerator that breathes through bright red feathery "lips." This isn’t a creature from outer space. Meet Riftia, a tube worm that lives in deep-sea vents, and learn the surprising...
NOAA Teacher at Sea Ruth Meadows Mar 1 2010 - 6:32pm In 2009, Ruth Meadows, a science teacher from Opelika Middle School in Opelika, AL was part of a team of international scientists that may have found a new species! Led by Mike Vecchione of the NOAA’s National Systematics Lab.	Deep-Water Larvacean Jul 27 2012 - 9:35am Found in Arctic waters, this rare deep-water species of larvacean, Oikopleura gorskyi, eats by filtering particles from the seawater it drifts through. Larvaceans build 'houses' around themselves made of protein that helps them filter the water even better. And when the filters in its house...
Deepsea Lizardfish Jun 12 2012 - 10:11am This lizardfish (Bathysaurus ferox) rests on the ocean bottom with its head slightly elevated—waiting to snatch prey with its large mouth and sharp teeth. It lives at depths of 600-3,500 meters (1,969-11,483 feet) and grows up to 64 centimeters (25.2 inches) long.	Big Red Jellyfish Aug 18 2010 - 4:44pm Marine biologists from MBARI nicknamed this startlingly large jellyfish—which grows over one meter (three feet) in diameter—"big red." It would be hard to miss, except that it lives at depths of 650 to 1,500 meters (2,000 to 4,800 feet). Big red uses four to seven fleshy "feeding arms" instead of...
