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 a shell around the larvacean and helps to filter particles out of the water for the larvacean to eat...

Found in the icy waters of the Arctic, Comb Jellies, or ctenophores like this one, of the Aulacoctena genus, are poorly known animals. With extremely fragile bodies, they are difficult to capture intact.

The world beneath the Arctic ice is magical, but cold. Divers have to tolerate temperatures of 30 degrees Fahrenheit (about -2° Celsius.) To stay warm they wear thermal undergarments and use special gear called dry suits. Sunlight filters through the ice layer bathing the underwater habitats...

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 melts in the south -- but as more and more sea ice melts because of climate change, they may not...

The ArcOD project brought together existing information about the diversity of Arctic ecosystems, collected new samples to fill in gaps of knowledge and looked for species and community changes over time in the region. Determining a baseline of information about the Arctic is especially important...

Scientists know the Greenland shark (Somniosus microcephalus) moves slowly in the Arctic's cold water. They also know that parasites attack the shark's eyes. But much about this animal remains a mystery. Marine biologist Greg Skomal says that's because the Greenland shark spends most of the year...
