Marine mammals encounter especially challenging conditions for sleep when they are at sea. Using advanced remote monitoring techniques, Kendall-Bar et al. found that wild northern elephant seals can sleep for less than 2 hours per day at sea and do so while diving to depths of around 300 meters. Unlike other marine mammals, they enter full REM sleep, with accompanying paralysis, but they do so at depths below those occupied by their predators.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Brain activity of diving seals reveals short sleep cycles at depth","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:33:00.917306","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-04-21","DateCreate":"2023-04-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000981095800001","VABBcode":null,"OpenAcc":0,"DOI":"10.1126/science.adf0566"},"refs":null,"anarec":{"AnaID":363792,"PubliDate":2023,"Pagination":"260-265","XtraPublOfAnaID":null,"ISBN":null,"Volume":"380","Issue":"6642","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43776,"SerRR":"Science (Washington).
