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...
This is the first photograph of a live giant squid ( Architeuthis ) in its natural habitat. It was taken in 2004 by two Japanese researchers who had suspended a long line from their research vessel...
Researchers use Autonomous Reef Monitoring Structures (ARMS) like this one to study the diversity of coral reef organisms. They leave the structures underwater for about a year. Then they retrieve...
When we think "Africa," we think of the "Big Five"—lions, elephants, leopards, buffalo and rhinos—that crisscross the African Savannah. Few would imagine that there could be more natural beauty on...
Good real estate is hard to find. This is as true underwater as it is on land. So when Smithsonian scientist Dr. Matthieu Leray built 18 potential homes for undersea creatures living on oyster reefs...
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...
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 icy cold and the light dim or absent. Yet believe it or not, lush coral...
Ever since fourth grade I’ve wanted to explore the creatures and landscapes of the deep ocean in a submersible. It took awhile, but I finally got my chance this summer as part of the Deep Reef...
The Census of Marine Life was a ten-year effort by scientists from around the world to answer the age-old question, “What lives in the sea?” The international effort to asses the diversity,...
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 zoologists inside the Curasub , a 5-person submersible. They're exploring the biodiversity of the deep reefs off Curaçao in the southern Caribbean. Read more and watch videos about the...
Far away from the volcanic CO 2 seeps, a healthy coral reef flourishes with a diversity of coral species. Closer to the seeps where the water is acidic, the corals barely even grow. Read more about...
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...
Sarah Gotheil, from IUCN Global Marine Programme , snapped this photo in the course of her research into fragile species and ecosystems. A new project led by IUCN will unveil the mysteries of...
As it clings to a red sea fan, a feather star ( Cenometra bella ) gently waves its slender arms—filtering bits of food from the water. Also known as sea lilies, feather stars are related to sea stars...
Marine World Heritage is a prestigious list of 43 marine ecosystems and biodiversity treasures from across the globe, including countries such as Australia, Iceland, Russia, South Africa, the...
Squids, octopuses and cuttlefish, such as this Australian Giant Cuttlefish ( Sepia apama ), compose just one group of animals that call seagrass beds home. Clams and worms bury themselves in the mud...
Enric Sala has spent much of his career looking for the ocean's "time machines" -- areas rich in biodiversity and largely unaffected by humans. In this recorded webcast , Sala, a National Geographic...
