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...
This month, our friends at National Geographic are featuring Smithsonian's own bio-scavenger, Chris Meyer and his work in one of our favorite places: Moorea , French Polynesia. In a beautiful meld of...
Expedition data went to the Arctic Ocean Diversity database of the Census of Marine Life to establish a baseline that will help to document change in the poorly known Arctic Ocean. Scientist Kevin...
Flower-like clusters of polyps make up this coral colony. Their pink color comes from the zooxanthellae living inside. More about coral reef ecosystems can be found in our Coral Reefs featured story .
This photo of Kingman’s Reef in the Line Islands shows what a healthy coral reef should look like. The water is crystal clear. A variety of richly colored corals carpet the seabed. And a native...
Discovering new species is an exciting quest, right? Well, some parts are—but after you find a cool-looking organism that you think is a new species, there's a lot more to be done. You have to...
In 1954 Smithsonian researchers dissected this squid specimen from the stomach of a lancetfish and added it to the Museum’s squid collection. Almost 50 years later, it helped scientists identify a...
The ocean is not as natural as it once was. Where there used to be large predators that we took for sea monsters, now there are tiny fish and jellyfish. But there are a few untouched places left in...
Like other sea snakes , the turtle-headed sea snake ( Emydocephalus annulatus ) has fangs and venom. But its venom is weak so, instead of defending with a bite, the species tends to react to danger...
You may not think of the ocean as a pharmacy but scientists are developing exciting new medicines from the sponges, corals, and other marine organisms found in the sea. Explore other videos that...
Dip your head below the water's surface in a mangrove forest and an entirely new ecosystem is revealed. The twisting mangrove roots, some of which don’t make it to the seafloor, support a great...
When you think of African animals, what do you think of? Probably the “Big Five:” lions, elephants, leopards, buffalo and rhinos. But Africa also has an incredible amount of marine diversity in the...
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...
About DROP DROP is a multidisciplinary Smithsonian project exploring the diversity of tropical deep reefs off the coast of Curaçao in the southern Caribbean. Deep reefs are natural extensions of...
Mangrove roots provide support for filter-feeders like sponges, mussels, oysters, and barnacles. These play an important role in keeping the water clear. More about mangroves can be found in our...
The Indonesian Archipelago is the heart of the Coral Triangle, a biodiversity hotspot for marine and terrestrial life. This diversity forms an important part of Indonesia's natural, cultural, and...
Sample the surprising diversity of deep-sea corals. See some of the ways they differ in color, shape, and size. Explore more in the multimedia feature " Coral Gardens of the Deep Sea ."
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...
