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...
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...
Every year as the sun disappears for the winter, the surface waters around Antarctica freeze into a slab of ice 10-feet thick, which effectively doubles the size of the continent. In the summer, 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...
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...
Three distinct types of killer whale, or orcas, can be found in the Antarctic, each with a different habitat and diet preference. One type of orca preys almost exclusively on the Antarctic minke...
The New Zealand Sub-Antarctic Islands site was inscribed on the World Heritage List in 1998. The islands are particularly notable for the abundance and diversity of nesting pelagic seabirds and...
An isopod stands on top of a glass sponge, extending its legs to find zooplankton. This delicate sponge is small, but some glass sponges can grow to the size of a 50-gallon drum and live for...
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...
For two months, Cassandra Brooks , a marine scientist with Stanford University, travelled on an ice-breaking ship through the Ross Sea in the Antarctica—and she filmed the whole thing. A camera...
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...
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...
“As we motored around Paulet Island in a Zodiac boat, these two curious penguins waddled across an iceberg to get a closer look at us.” -- Nature's Best photographer, Phillip Colla . See more...
The white body of the snow petrel blends in with the stark Antarctic landscape, accentuating the beautiful black eyes and beak of this seabird. They hunt in the sea ice, feeding on krill and fish...
Looking through this iceberg's reflection in the Antarctic water, you can see the iceberg below the surface—some 90% of its total volume. Icebergs are pieces of freshwater ice broken off of glaciers...
