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 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 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...
"Cold-Water Diving: Going to Extremes for Research" is a video produced by Woods Hole Oceanographic Institution (WHOI) that shows the focus needed to do scientific work in cold water. The gear is...
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...
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 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...
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...
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...
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 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...
Sea stars ( Odontaster validus ) and sea urchins ( Sterechinus neumayeri ) spread over an algae-covered seafloor off the coast of Antarctica. These two species are often found living in association...
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...
Did you know that over 17,000 species thrive in the deep sea where no light penetrates the ocean waves? Or that an old restaurant menu can teach us about the history of fish populations? Or that...
“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...
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...
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...
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...
