Cashes Ledge is a wild, special place in the heart of the Gulf of Maine. This underwater mountain range is home to a great diversity of life, with colors typically associated with a coral reef rather...
Smithsonian researchers collected a cave basslet ( Liopropoma mowbrayi ) from the deep reefs of Curaçao , in the southern Caribbean. They used a state-of-the-art submersible to obtain the specimen...
The incredible variety of marine life—in numbers, body form, behavior, and more—is at the heart of Citizens of the Sea , an irresistible plunge into the surprising world beneath the waves. Author...
Sharks come in all sizes. The largest is the whale shark , which has been known to get as large as 18 meters (60 feet). The smallest fits in your hand. And the great white shark is somewhere in the...
These star-shaped grains of sand, collected from southern Japan, look like miniature works of art -- but they were not sculpted by an artist. They are the shells of microscopic organisms called...
Deep sea animals have to live in a very cold, dark, and high-pressure environment where they can't see a thing! To survive there, they've evolved some very strange adapations. Some make their own...
Climate and sea changes in the Southern Ocean create conditions that favor the growth of salps over krill , the latter of which are a vital food source for seals, whales, and penguins. Salps are...
We have arrived as the advanced scouting party to the scene of this year's field work location: Pemuteran, a small fishing village in northwest Bali. More importantly, we are sitting squarely at the...
On many of the dives, Oceana's 2011 Baltic Sea expedition team saw little wildlife in the oxygen-depleted areas. But near some marine protected areas, the crew saw an array of marine life, including...
Dr. Claude Payri, a researcher working on the Moorea Biocode Project , collects samples on the reef slope of Moorea, French Polynesia. More about the Island of Moorea can be found in our Scientists...
Scientists on the tiny island of Moorea, in the Pacific, are gathering one of every life form large enough to pick up with tweezers. They're on a quest to build a detailed catalog of the entire...
Nudibranchs are mollusks that have evolved from shelled ancestors. Like the reddish-orange Coryphella verrucosa shown here, they're often noted for their vibrant colors and striking forms. View other...
Sea stars are important members of marine ecosystems, especially in the tropics. We may think of tropical coral reefs as being home mainly to fish and corals, but in fact these habitats are home to a...
Smithsonian researchers are using this five-person submersible to study the biodiversity of the deep reefs of Curaçao in the southern Caribbean. Read about their adventures in the Summer in a Sub...
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...
A candy basslet ( Liopropoma carmabi ) was just one of the specimens Smithsonian scientists collected from the deep reefs of Curaçao , in the southern Caribbean. To study biodiversity far below the...
Coral reefs are bustling cities of marine life, until rising ocean temperatures turn them into ghost towns. Can reefs spring back from devastating bleaching events? In this episode of the Podcast of...
Photographer David Liittschwager took a 12-inch metal frame to Moorea, French Polynesia, and four other disparate environments to see how much life he could find in one cubic foot. Read more about...
