  abstract = {{M}etabolomics is a powerful approach to investigate the effect of environmental conditions on metabolite variations in marine algae. {H}ere, we focused on crustose coralline algae ({CCA}), a group of calcifying, red algae which play an important role on coral reefs through their interactions with corals and contribution to coral reef formation. {D}espite their ecological importance, little is known about their metabolome and how it varies with environmental conditions and phylogeny. {U}sing an untargeted metabolomic approach, we explored the metabolomic fingerprints of seven {CCA} species (order: {C}orallinales) commonly found on the coral reefs of {M}oorea, {F}rench {P}olynesia. {W}e developed an extraction method to characterize the {CCA} metabolome on two sample types (whole fragment and surface only) and explored the chemical variations of {CCA} across species, reef habitat and microhabitat. {T}he extraction method successfully characterized the {CCA} metabolome, as demonstrated by a technical variability lower than the biological variability for both sample types. {T}he {CCA} metabolome was species-specific and a correlation was found between phylogenetic taxonomy and metabolomic profiles of the different species. {M}oreover, the metabolomic composition of certain species differed between the back and fore reef habitats and between exposed and cryptic microhabitats. {T}hese results highlight a high variability in the {CCA} metabolome mediated by phylogeny and environmental conditions. {T}his study provides valuable insights into the sources of metabolomic variation in {CCA}. {I}t lays the groundwork for exploring the ecological functions of the {CCA} metabolome and its potential use as a tool to assess organismal and ecosystem health.},
