Using a time-lapse camera at 8,074 m in the Peru–Chile Trench (SE Pacific Ocean), we provide the first in situ observations of locomotory activity for the elasipodid holothurian Elpidia atakama Belyaev in Shirshov Inst Oceanol 92:326–367, (1971). Time-lapse sequences reveal ‘run and mill’ behaviour whereby bouts of feeding activity are interspersed by periods of locomotion. Over the total observation period (20 h 25 min), we observed a mean (±SD) locomotion speed of 7.0 ± 5.7 BL h-1, but this increased to 10.9 ± 7.2 BL h-1 during active relocation and reduced to 4.8 ± 2.9 BL h-1 during feeding. These observations show E. atakama translocates and processes sediment at rates comparable to shallower species despite extreme hydrostatic pressure and remoteness from surface-derived food.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Functional effects of the hadal sea cucumber <i>Elpidia atakama</i> (Echinodermata: Holothuroidea, Elasipodida) reflect small-scale patterns of resource availability","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:32:51.034724","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2016-05-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000299182500008","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00227-011-1767-7"},"refs":null,"anarec":{"AnaID":256212,"PubliDate":2011,"Pagination":"2695-2703","XtraPublOfAnaID":null,"ISBN":null,"Volume":"158","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
