Hedbergella sliteri - this specific specimen is the "holotype" for this species. That means it is the reference point for what all members of the species should look like. This specimen was...
Scripps scientist Gerald Kooyman's expeditions have documented climate-induced changes to emperor penguin habitat in Antarctica. Learn more about life at the poles or check out this emperor penguin...
The National Ice Center’s work is focused on ensuring safe and efficient navigation, but it also supports scientific research and provides crucial information used by scientists to better monitor and...
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...
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...
Antarctica is almost entirely covered by ice sheets up to two miles (3 km) thick, which contain roughly 70% of the world’s freshwater. The great ice sheets spill out to sea as floating ice-shelves...
Seasons in the Ross Sea are marked by ice freezing and melting, and these processes mix the seawater and redistribute salt and nutrients. The influx of nutrients cause phytoplankton to bloom, forming...
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...
Weddell seals grind their teeth on holes in the ice to keep them open to their comings and goings between ocean and air. Their dives can last over an hour when they are looking for an opening in the...
Humpback whales ( Megaptera novaengliae ) are the most abundant baleen whale in the nearshore waters around the Antarctic Peninsula. They, along with millions of penguins, seals, seabirds, and other...
The dark seafloor beneath the ice is covered with sea stars, urchins and ribbon worms looking for their next meal, which can come from sponges, dead animals that float to the sea floor, or even other...
On average, Arctic sea ice has decreased by four percent per decade since the late 1970s. But at the same time, Antarctic ice has increased by 1 percent. Scientists are investigating why . More about...
Despite the cold and dark environment, soft-bodied animals like anemones abound under the ice. Using their sticky arms, they grab zooplankton, which can be hard to come by during the long winter with...
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...
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...
At the Poles, Life Thrives Located beside the Shores and Shallows gallery (which highlights different kinds of coastal ecosystems around the world), the Poles area will take you to the ends of the...
