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...
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...
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...
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,...
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...
Reef sharks rarely get any love. These sharks, comprising several species, loiter around coral reefs, snacking on small fish, squids and crustaceans. And while their size is nothing to smirk at—5-10...
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...

Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
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...
Ice divers use a quadrat to study the density of creatures living on the underside of Arctic ice floes. A quadrat is a standardized square used to take sample measurements that allow researchers to...
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...
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 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...
A student from the University of Cape Town in South Africa uses a field guide to help identify organisms during a shoreline survey at Cape Columbine.
Ocean Sampling Day 2014 will be the largest ocean sampling effort ever orchestrated on a single day. Over 170 sites globally will participate, with every participating site represented on the map...
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...
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...
