Study Reveals Sleeping Habits of Elephant Seals at Sea
Science & EnvironmentA new study shows that elephant seals average just 2 hours of sleep per day when they are at sea. This video by Scripps Institution of Oceanography postdoctoral fellow Jessica Kendall-Bar uses data-driven animations to show how these seals sleep for 10 minutes at a time during deep, 30-minute dives in which they often spiral downward while fast asleep. Kendall-Bar conducted the research while she was a graduate student at UC Santa Cruz. Study co-authors include a team of researchers affiliated with UC Santa Cruz and several other research organizations.
