LATEST CATCH

In the icy waters of the Arctic , a deep-water larvacean (aka “sea tadpole” because it looks like a tadpole) drifts through the water in its 'house.' This house is made of protein and creates almost a shell around the larvacean...

DIVE DEEPER

Travel to the ends of the earth—literally—and discover the polar ocean basins. Both the Arctic Ocean and the Southern Ocean...
Humpback whales ( Megaptera novaengliae ) can be found in Antarctic waters during the spring and summer in the Southern hemisphere, where they gorge on their main food source: tiny krill. How do they...

The Arctic Tern could really be called the Arctic-Antarctic Tern. It has the longest migration of all birds, flying from breeding grounds near the North Pole to wintering grounds off Antarctica. That...
This pair of sea butterflies ( Limacina helicina ) flutter not far from the ocean's surface in the Arctic. Sea butterflies are a type of sea snail, but instead of dragging themselves around the...
This species of amphipod , Eusirus holmii , was found both at the surface of Arctic waters and as deep as 2000 meters (6562 feet). Researchers have found that while the amphipod inhabits the sea ice...
Recent Antarctic expeditions have documented climate-induced changes to emperor penguin habitats and impacts on how the penguins feed, breed, and raise their young.
Lying on the ice with a few friends is not an unusual way to spend time for walruses, who tend to be sociable animals. Their groups can range from tens to thousands. Each individual herd has a...
Several species of amphipod like this one, Gammarus wilkitzkii , live permanently within Arctic sea ice . These animals are endemic, meaning they only live here. They acclimate to a wide range of...
Bright colors seem to jump off of this comb jelly, or ctenophore. The rainbow effect appears when light emanates from comb jellies' namesake combs, which are rows of cilia that run up and down their...
Scientists use a multinet to collect Arctic zooplankton samples from different depth layers in the water column .
It takes special equipment and many warm layers of clothing to dive safely beneath Arctic sea ice . Ice divers look for holes in a melt pond in order to enter the frigid waters.
Found in Arctic waters, this rare deep-water species of larvacean , Oikopleura gorskyi , eats by filtering particles from the seawater it drifts through. Larvaceans build 'houses' around themselves...
Arctic cod have a special protein that keeps their blood from freezing in ice-cold Arctic waters.
Chrysaora melanaster , one of the largest jellyfish commonly found in the Arctic, swims underneath the Arctic ice . Its tentacles can stretch to more than 3 meters long and pack a mean sting for...
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...
Sea ice is typically viewed as the domain of physical and natural scientists, the oceanographers, marine biologists, climate modelers, and navigators of the world. It is easy to forget another...
The Ross Sea, a 1.9 million square mile (3.6 million square km) stretch of ocean off the coast of Antarctica, has been nicknamed “The Last Ocean.” And it’s not just a ploy to get your attention. In...
During the winter and spring months, tagged fur seals migrate thousands of miles in open water. Scientists are watching this species closely in order to determine the mystery of its population...
