  abstract = {{T}he specific identification of three major morphotypes of the tropical holopelagic {S}argassum species causing massive strandings on the {A}frican and {C}aribbean coastlines was attempted by morphological characterisation as well as quantitative and qualitative analyses of several metabolites. {O}f the 25 morphological variables studied on 208 samples from the {N}orth {A}tlantic {O}cean, 22 were used to establish a dichotomous identification key, allowing without any doubt the identification of each morphotype based on their morphological criteria alone. {W}e also attempted to differentiate morphotypes using chemical fingerprintings ({HR}-{MAS} {NMR}) and markers by analysing pigment level and composition using {H}igh {P}ressure {L}iquid {C}hromatography, terpene profiles by {T}hin {L}ayer {C}hromatography, phenolic compound levels by the {F}olin-{C}iocalteu assay and structures by 2{D} {N}uclear {M}agnetic {R}esonance spectroscopy, and fatty acid composition by {G}as {C}hromatography. {W}hile pigment level and composition, terpene profiles, and phenolic contents were not discriminating, quantification of eight fatty acids enabled the differentiation of the three morphotypes. {F}urthermore, phlorotannin purification permitted their structural characterisation allowing discrimination between the three morphotypes. {O}ur study highlights the potential of the free fatty acid profile and phlorotannin structure as good chemomarkers in order to discriminate between the three morphotypes of holopelagic {S}argassum.},
