This deep-sea urchin (Echinocrepis rostrata) is an important “bulldozer.” It turns over sediment and exposes prey as it moves across the ocean floor, leaving a trail of tracks behind. This photo was taken about 220 kilometers (137 miles) off the California coast and 4,000 meters (13,123 feet) below...

A huge colony of brittlestars (likely Ophiacantha rosea) covers the peak of a seamount in the deep ocean. What’s the attraction? Food! Their arms reach out for tiny food particles carried by the swift Antarctic Circumpolar Current.

A diet of algae and seagrasses gives this turtle (Chelonia mydas) greenish colored fat—and its name. Weighing as much as 500 pounds, the threatened green sea turtle lives its life at sea, with only females coming to shore to lay eggs. See a slideshow with more pictures of beautiful but threatened...

Like octopods and cuttlefishes, giant squid have eight arms. But they use their two much longer feeding tentacles to seize prey. The tentacles have powerful suckers at the ends. More about the giant squid can be found in our Giant Squid featured story.

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...

This may look like a mane of hair, but it’s actually baleen from a North Atlantic Right Whale. Although it looks soft and furry, dried baleen is quite stiff, which made it useful for creating structure in a number of consumer products, including whips and umbrellas. Discover more about this species...

I have a vivid childhood memory of sitting under the Blue Whale model hanging in the Natural History Museum in London, eating an ice cream and wondering “How in the world did that whale get so big?” These days we are closer to knowing the answer. Over the past several years, a group of researchers...

“This humpback uses its lower jaw to strain fish off the water’s surface as sea birds snatch their own meals right out of the whale’s open mouth.” -- Nature's Best photographer, Bryce Flynn. See more beautiful ocean photos in our slideshow of winners from the 2010 Nature's Best Ocean Views photo...

The sargassum frogfish Histrio histrio (Antennariidae) is a small but voracious predator - it can ingest animals up to it’s own size! The fins of the frogfish are perfect for creeping around in the algae and stalking unsuspecting prey.

Humpback whales (Megaptera novaengliae) are the most abundant baleen whale in the nearshore waters around the Antarctic Peninsula. They, along with millions of penguins, seals, seabirds, and other whales, feed primarily on Antarctic krill (Euphausia superba) during summer months.

This scanning electron micrograph magnifies the tiny teeth that cover the surface of the giant squid’s tongue-like organ, or radula. Seven rows of sharp teeth help direct tiny pieces of food down the squid’s esophagus (only three are shown here). Because the esophagus passes through the brain...

It's hard to imagine a 2000-pound animal launching itself out of the water while hunting, but the great white shark does just that. This spectacular behavior is called breaching, and great white sharks breach in order to catch fast-moving prey like seals.

Recent Antarctic expeditions have documented climate-induced changes to emperor penguin habitats and impacts on how the penguins feed, breed, and raise their young.

Hundreds of powerful suckers stud the flattened club at the end of the giant squid’s long feeding tentacle. They help the squid capture and hang on tightly to its prey. They also leave deep scars in the skin around the mouths of sperm whales as the squid fight to escape from the whale’s jaws. More...

Snow on land can make some people grumpy, but the magical-looking flakes and a beautiful layer on the trees can turn even disenchanted adults into gleeful children again. But what is the ocean equivalent of a snowy night?

Sperm whales have conical teeth on their long, narrow, lower jaw. The teeth fit neatly into sockets in the upper jaw, which has no teeth. This arrangement is a perfect adaptation for slurping up soft-bodied squids—giant or otherwise. The sperm whale is listed as Vulnerable on the IUCN's Red List of...

Smithsonian Marine Science Network Postdoctoral Fellow, Seabird McKeon, returns from the Smithsonian field site in Belize. Together with Dan Barshis of Stanford University, Seabird reports on the seemingly invisible inhabitants of drifting sargassum seaweeds. As with many parts of the ocean, a ball...

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...

Jellyfish and comb jellies are gelatinous animals that drift through the ocean's water column around the world. They are both beautiful—the jellyfish with their pulsating bells and long, trailing tentacles, and the comb jellies with their paddling combs generating rainbow-like colors. Yet though...

The comb jelly (ctenophore) Thalassocalyce inconstans is found in shallow to deep water in the Atlantic Ocean, Mediterranean Sea, and sometimes in warmer Pacific Ocean waters off the coast of California -- although this one was photographed in the Sargasso Sea by Census of Marine Zooplankton...

One of the first signs of a sick coral reef is seaweed creeping across the corals, stealing their precious sunny real estate. Healthy corals, however, aren't completely hopeless: in some reefs, small fishes, such as this broad-barred goby (Gobiodon histrio), help eat the seaweeds away....

Stinging cells (nematocysts) line the tentacles of this moon jelly (Aurelia aurita). Upon contact with prey or a predator, a venom-laden harpoon shoots out to stun or kill. Read more about jellyfish anatomy in our jellyfish and comb jellies overview page.
