Nine shell colours were identified: green (most common), grey, pink, cream, brown, orange, white, black and purple. The species habitat was also examined using three rock characteristics: volume; turnover frequency, caused by hydrodynamic disturbance; and chromatic composition. Chitons were most frequently encountered on the undersides of rocks of intermediate volume which experienced medium-intensity hydrodynamic disturbance, and which harboured a chromatically rich biotic community. These findings were in agreement with the Intermediate Disturbance Hypothesis. As chitons depend on the biotic community on rocks for food and shelter, a greater variety of colours could increase the chances of camouflage of the morphs against the background, favouring crypsis. It is likely that the frequency at which intermediate-volume rocks are overturned  thus exposing the chitons on them to light  would be sufficient for visual predators to act as selective agents.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Shell colour polymorphism in the chiton <i>Ischnochiton striolatus</i> (Gray, 1828) (Mollusca: Polyplacophora) and habitat heterogeneity","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-29 01:31:37.739962","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2017-07-31","DateCreate":"2005-08-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000231057700011","VABBcode":null,"OpenAcc":0,"DOI":"10.1111/j.1095-8312.2005.00513.x"},"refs":null,"anarec":{"AnaID":75418,"PubliDate":2005,"Pagination":"543-548","XtraPublOfAnaID":null,"ISBN":null,"Volume":"85","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42441,"SerRR":"Biological Journal of the Linnean Society.
