In the summer they leave the ice and forage in the open ocean. A recent National Oceanic and Atmospheric Administration (NOAA) Fisheries study found that three species of Arctic seals are experiencing impacts of climate change and they are losing body mass at alarming rates. Description: This species is even more sexually dimorphic than the other sea lions. It is estimated that fewer than 100 ribbon seals are killed each year by Alaskan natives for subsistence purposes but this estimate is unreliable and the actual figure may be higher.
