The bowhead whale has a massive, bow-shaped skull to break through thick Arctic ice, and more blubber than any other whale.
Standing at twice the height of the Adélie penguins, emperor penguins are the largest of the penguin species and can grow to be 100 pounds. This species breeds directly on the ice: a female lays her...
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...

This new species of deep-water sea cucumber ( Elpidia belyaevi ) was discovered by Census of Marine Life researchers in the frigid waters of the Arctic . Since the 1800s, researchers observed sea...
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...
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...
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...
An emperor penguin chick ( Aptenodytes forsteri ) huddles under its mother's legs to keep warm in the long Antarctic winter. Learn more about research on emperor penguins and other Antarctic...
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.
In the spring of 2011, a research crew from Oceana spent two months in the brackish Baltic Sea . The Baltic faces challenges from pollution, algae blooms, over fishing, and invasive species. Oceana...
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...
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...
Small Adélie penguins live throughout the Antarctic, but are most abundant in the area of the Ross Sea. They lay eggs on the few rocky outcrops of land not covered in ice. Scientists have determined...
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...
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...
To people living in warm climates, all ice looks the same. But if you live day-in and day-out on sea ice, like the Inupiaq people of Alaska, you would find that there are many kinds of ice, all...
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...
