Trophic structure of vermetid reef community: High trophic diversity at small spatial scales

► We investigated the organic matter sources use by vermetid reef cuvette community. ► Stable isotope ratios (δ13C, δ15N) were used to describe the trophic web. ► Both benthic and pelagic OM sources contributed in different extents. ► Three different trophic pathways were identified within the cuvette. ► Predators revealed a high specialization in each of the three trophic pathways.
