The burrow symbiosis of alpheid shrimps is poorly studied in the context of ecology, probably because the cryptic infaunal nature of the relationship is hard to observe. The limited knowledge of the pattern of burrow use by alpheid shrimps leaves a gap in our understanding of their evolutionary history. We described and compared the behavior of <i>Stenalpheops anacanthus</i> Miya, 1997 and <i>Athanas japonicus</i> Kubo, 1936, two alpheid species living symbiotically in the burrows of the same host, <i>Upogebia yokoyai</i> Makarov, 1938. We found that both alpheid species used <i>U. yokoyai</i> burrows in aquaria, but their burrow use patterns were quite different. The average time taken for <i>S. anacanthus</i> to enter the burrow for the first time was much shorter (1 min) than that of <i>A. japonicus</i> (13 min). Subsequently, <i>S. anacanthus</i> made longer use of the burrow (80% of the observation period) than <i>A. japonicus</i> (49%). The tail-first exit frequency, which may indicate a sudden expulsion from the burrow by the host, was more frequent in <i>A. japonicus</i> (25%) than in <i>S. anacanthus</i> (7%). Such differences could be attributed to the nature of the symbiotic relationship, obligate in <i>S. anacanthus</i> but facultative in <i>A. japonicus</i>. Because of the diversity of symbiotic lifestyles, there is considerable potential to study the ecology and evolutionary biology of burrow-symbiotic alpheids further.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Species-specific patterns of the use of burrows of <i>Upogebia</i> Leach, 1814 (Decapoda: Gebiidea: Upogebiidae) by the symbiotic alpheid shrimps <i>Stenalpheops anacanthus</i> Miya, 1997 and <i>Athanas japonicus</i> Kubo, 1936 (Decapoda: Caridea: Alpheidae) as revealed by laboratory quantification","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:32:08.194730","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-07-09","DateCreate":"2021-07-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000649390100009","VABBcode":null,"OpenAcc":0,"DOI":"10.1093/jcbiol/ruaa095"},"refs":null,"anarec":{"AnaID":339921,"PubliDate":2021,"Pagination":"ruaa095","XtraPublOfAnaID":null,"ISBN":null,"Volume":"41","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43037,"SerRR":"Journal of Crustacean Biology.
