Hermit crabs, like this one collected in Moorea, usually protect their soft, vulnerable abdomens from predators by reusing empty snail shells. They are picky home owners and they will trade shells...
In 2009, Ruth Meadows, a science teacher from Opelika Middle School in Opelika, AL was part of a team of international scientists that may have found a new species! Led by Mike Vecchione of the NOAA’...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
Now that the Census of Marine Life is over, we’re checking in with some of the researchers to hear about their favorite expedition, what they learned, and how the Census and its findings continue to...
The rough patches of skin known as callosities occur in unique patterns on all North Atlantic right whales and help researchers identify and track individual whales. This whale is named Phoenix. More...
The long silver tool shown here is a piece of traditional Australian fishing gear called a “yabbie pump.” Researchers use the device to collect burrowing shrimp and other fast-moving animals from the...
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...
How many animals swim in the sea? It's not easy to count them all. To get a feel for the ocean's diversity, scientists, such as those involved in the Census of Marine Life , sail out on research...
These watercolor sketches of Trapezia crabs were drawn by Frederick Bayer, a former Smithsonian coral biologist, in 1947. Trapezia crabs live on and within corals, feeding on their tissue and mucus,...
Cooks Bay in Moorea is one of the places that researchers are scouring in their quest to collect one of every life form big enough to pick up with tweezers. In the background is Mt. Rotui—the...
Scientists from the Integrated Ocean Drilling Program (IODP) collect sediments drilled from Earth’s crust. This marine research program supported by 24 countries is increasing our understanding of...
Diving to survey, sample, and manage marine life takes a great deal of skill and knowledge. This diver is sampling the seafloor, also known as the benthic zone. This kind of sampling is important for...
Oceanographer and executive director of Oceana Europe , Xavier Pastor, led the Baltic Sea expedition. The crew covered more than 7,000 nautical miles and completed more than 130 dives to collect...
A drawing of Phoenix from the Right Whale Catalog documents her callosity pattern and other identifying marks. More about whales can be found in our Tale of a whale featured story .
This brightly colored squat lobster collected in Moorea is a common find among the coral heads. Although called lobsters, this group of crustaceans is more closely related to hermit crabs than to...
So far, researchers have developed DNA barcodes to accurately identify 4,600 of the more than 29,000 known fish species. Atlantic cod is an economically important fisheries species. However, it's...
By now, you have probably heard of The Great Pacific Garbage Patch . The name conjures the image of a floating island made of familiar plastic trash such as soda bottles and plastic bags, disposable...
If you are a bird watcher you have probably heard of the Christmas Bird Count. The first one occurred on Christmas Day in 1900 at a variety of locations throughout North America, and it has since...
