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...
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...
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,...
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...
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...
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...
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...
In recent years, I have taken to watching flying fish along the Maine coast. Not the usual flying fish that skim over tropical seas, but fish dangling from the beaks of flying puffins. Puffins are...
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...
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.
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 .
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...
New England Aquarium researchers Dr. Moira Brown and Yan Guilbault conducting aerial surveys for North Atlantic right whales over the Roseway Basin, Canada. More about right whales can be found in...
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...
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...
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...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
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...
