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...
There are different types of beaches and multiple factors that influence the formation of sand. Many beaches may look alike, but they are actually very different from each other. Wave patterns,...
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...
A scorpion found in a mangrove. More about mangrove ecosystem can be found in our Mangroves featured story .
As 10 years of intensive research draw to a close, the Census of Marine Life has released the most comprehensive inventory of life in the ocean to date. This landmark collection of scientific papers...
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...
Mangroves canopies support an amazing array of life—including this mangrove yellow warbler ( Dendroica petechia bryanti ), the most common songbird in the mangroves of the Caribbean’s Mangal Cay...
A specimen from the Smithsonian’s squid collection and videos of a mystery squid helped scientists identify a new family of deep sea squid—the Magnapinnidae, known as the bigfin squids. More about...
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...
Male fiddler crabs, like this one collected on Moorea, wave their enlarged claw as way of signaling to other crabs, especially during mating season. Learn more about the Island of Moorea in the...
Dr. Clyde Roper, Smithsonian zoologist and squid expert, tries to measure up to a giant squid specimen (Architeuthis) from New Zealand. The squid wins. More about the giant squid can be found in our...
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...
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...
Today’s discoveries about our planet’s biological diversity build upon the research of previous generations of scientists. The Biodiversity Heritage Library (BHL) is a digital library committed to...
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...
Nancy Knowlton, Smithsonian's Sant Chair for Marine Science, puts up an Autonomous Reef Monitoring Structure (ARMS) during a dive in the Red Sea. These small underwater “condos” have been placed...
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...
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...
