Unlike the majority of intertidal chitons so far studied, <i>A. gemmata</i> rests in well-defined homes actively dug in the rock. Homes proved to be not strictly individual and periodically interchangeable. A complex aggressive behaviour was recorded in the field when two animals came in contact at home. When competing for ownership of a resting site rival chitons may suppress their nocturnal feeding activity. Despite its strong home-related territoriality <i>A. gemmata</i> showed no mutual exclusion on the feeding area. The highly specialized resting habits clearly protects <i>A. gemmata</i> from its most important predator, the toad fish <i>Arothron immaculatus</i>. The behaviour of <i>A. gemmata</i> is compared to that of other chitons and gastropods, and the current hypotheses concerning the adaptive value of the homing behaviour in littoral molluscs are discussed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Competition for the home and aggressive behaviour in the chiton <i>Acanthopleura gemmata</i> (Blainville) (Mollusca: Polyplacophora)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:32:14.069390","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1983,"MonPub":null,"DateUpdate":"2022-04-15","DateCreate":"2016-10-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1983RV22000003","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/BF00366651"},"refs":null,"anarec":{"AnaID":262226,"PubliDate":1983,"Pagination":"15-20","XtraPublOfAnaID":null,"ISBN":null,"Volume":"14","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42413,"SerRR":"Behavioral Ecology and Sociobiology.
