To document fragile organisms found in the Arctic , scientist Kevin Raskoff builds special aquaria on the ship to photograph of live critters that have been captured.
Walruses use sea ice as platforms on which to nurse their young and launch their dives for clams and other bottom-dwellers. Each spring, walruses move northward to stay close to these perches as ice...
New technology is making it possible for scientists to go where they’ve never gone before, the depths of the icy Arctic Ocean . By collecting organisms and mapping the seafloor, researchers can...
Small amphipods, the blue bug-like creatures, can be seen here catching a ride on this enormous sea spider as it makes its way across the bottom. Many Antarctic creatures, like the dinner-plate-sized...
The elegant Antarctic minke whale feeds on krill (tiny crustaceans) during the winter. Groups of minke whales often are found on the edges of pack ice feasting so that they can grow thick layers of...
This shadowy fish, Trematomus bernacchii , is well adapted to the ice-cold water of the Antarctic: its blood comes equipped with natural antifreeze. This is a necessary adaptation because the...

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...
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...

At the ends of the Earth, life thrives despite extreme conditions. In the Arctic and Southern Oceans, organisms have evolved adaptations to cope with year-round cold and six months of darkness. But...
Using an ROV (Remotely-Operated Vehicle) equipped with a high-definition video camera, scientists can observe the life that flourishes beneath the Arctic ice . On this expedition, they discovered...
