This may have important implications for element cycling and biogeochemical processing. However, current studies have only targeted relatively large zooplankton specimens ignoring ubiquitous, omnipresent small (&lt;1 mm) copepod species. Using oxygen sensitive nanobeads and a phosphorescence imaging approach, we imaged the internal O2 distribution of living copepods for 2 small species with benthic lifestyles: Tachidius discipes and Nitocra spinipes. The internal hypoxic O2 distribution was strongly dependent on position and content within the gut and on the ambient O2 levels experienced by the animals. Anoxia was only rarely encountered, but extrapolations and measurements at lower ambient O2 levels strongly suggest that even small copepods will have anoxic interiors when exposed to O2-depleted environments such as surface sediments, detrital-enriched material patches or pelagic oxygen minimum zones.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Hypoxic guts in two small benthic copepods, <i>Tachidius discipes</i> and <i>Nitocra spinipes</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-09-15 15:13:09.091645","timezone_type":1,"timezone":"+02:00"},"AuthorKeywords":"Hyposia; Gut microbiome; Optical O<sub>2</sub> sensing ","OtherDescriptors":null,"Notes":null,"AnaPub":2026,"MonPub":null,"DateUpdate":"2026-09-15","DateCreate":"2026-09-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001849253500004","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":447891,"PubliDate":2026,"Pagination":"1-7","XtraPublOfAnaID":null,"ISBN":null,"Volume":"791","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
