Coral gardens are considered to be hotspots of biodiversity and ecosystem functioning, due to the important structural and biogeochemical role of cold-water coral (CWC) species. Despite the importance of CWCs as habitat forming and mediating species in bentho-pelagic coupling processes, our understanding on their biology and ecophysiology is still very limited. Moreover, despite an increase in studies on deep reef-forming species, information on cold-water octocoral and antipatharian species is still very scarce. The present study aims at determining aspects of the feeding biology of two common indicators of Vulnerable Marine Ecosystems (VMEs) in the Azores Archipelago: the gorgonian Dentomuricea aff. meteor and the antipatharian Antipathella wollastoni. By using controlled experiments in aquaria, we aim at determining the feeding preferences and assimilation efficiencies of the target species upon availability of live phytoplankton, live zooplankton and dissolved organic matter.
