Endemic organisms have convergently evolved similar colors and patterns, but quantitative assessments of camouflage strategies are lacking. Here, spectral camouflage of two crab species (<em>Portunus sayi</em> and <em>Planes minutus</em>) was assessed using hyperspectral imagery (HSI). Crabs matched <em>Sargassum</em> reflectance across blue and green wavelengths (400–550 nm) and diverged at longer wavelengths. Maximum discrepancy was observed in the far-red (i.e., 675 nm) where Chlorophyll <em>a</em> absorption occurred in <em>Sargassum</em> and not the crabs. In a quantum catch color model, both crabs showed effective color matching against blue/green sensitive dichromat fish, but were still discernible to tetrachromat bird predators that have visual sensitivity to far red wavelengths. The two species showed opposing trends in background matching with relation to body size. Variation in model parameters revealed that discrimination of crab and background was impacted by distance from the predator, and the ratio of cone cell types for bird predators. This is one of the first studies to detail background color matching in this unique, challenging ecosystem at the air-sea interface.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Use of hyperspectral imagery to assess cryptic color matching in <i>Sargassum</i> associated crabs","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2018-12-19","DateCreate":"2018-12-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000360932800031","VABBcode":null,"OpenAcc":1,"DOI":"10.1371/journal.pone.0136260"},"refs":null,"anarec":{"AnaID":304187,"PubliDate":2015,"Pagination":"e0136260","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":"9","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":123954,"SerRR":"PLoS One.
