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 species of amphipod , Eusirus holmii , was found both at the surface of Arctic waters and as deep as 2000 meters (6562 feet). Researchers have found that while the amphipod inhabits the sea ice...

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...
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...
