Table 2 aMFs present in at least one ST or MC sample per sponge species. CAS RN refers to the registration number in the Chemical Abstract Service database, while match score refers to annotation confidence (cosine score between the experimental MS/MS spectra and the reference library MS/MS spectra). These spectral annotations correspond to level 2 based on MSI standards and could correspond to stereoisomers or closely related isomers
