The first choice of prey, the total number of prey choices made, and the time spent on each prey target was recorded, results indicating that each nudibranch had strong preferences for specific prey species. Preferences were significant when the time spent grazing on prey was taken into consideration. <i>Goniobranchus aureomarginatus</i> had a strong preference for the undescribed Dictyodendrillid sponge, while <i>Ceratosoma ameonum</i> preferred <i>Dysidea teawanui</i>. The results of the feeding-choice experiments matched observations in the wild. Chemical analysis of the undescribed Dictyodendrillid sponge led to the isolation and characterisation of six known bioactive metabolites, dictyodendrin C (<strong>1</strong>), D (<strong>2</strong>) and F (<strong>3</strong>), as well as denigrin E (<strong>4</strong>), dactylpyrrole A (<strong>5</strong>) and lamellarin O1 (<strong>6</strong>). Two of the known compounds, dictyodendrins C (<strong>1</strong>) and F (<strong>3</strong>) were also isolated from <i>G. aureomarginatus</i> individuals. Chemical analysis of <i>D. teawanui</i> afforded ergosterol peroxide, 5α,8α-epidioxy-24-methylcholesta-6,22-dien-3β-ol (<strong>7</strong>). The structures of the isolated natural products were elucidated based on extensive analysis of 1D and 2D NMR data.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Investigation of the dietary preferences of two dorid nudibranchs by feeding-choice experiments and chemical analysis","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-10 01:33:17.805615","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2024-01-02","DateCreate":"2024-01-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001031445700001","VABBcode":null,"OpenAcc":1,"DOI":"10.1007/s10886-023-01444-z"},"refs":null,"anarec":{"AnaID":380408,"PubliDate":2023,"Pagination":"599-610","XtraPublOfAnaID":null,"ISBN":null,"Volume":"49","Issue":"9-10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":135893,"SerRR":"Journal of Chemical Ecology.
