Research by marine biologists from Wageningen University has shown that feeding on zooplankton by scleractinian corals has been greatly underestimated.

Swiftia exserta (Duchassaing and Michelotti, 1864)
Swiftia exserta is a deep water Atlantic Octocoral, both ahermatypic and azooxanthellate. This coral species thrives in particle-rich waters, with high flow rates and low light levels. It requires ample feeding with live zooplankton or plankton-analogues in the 5 - 800 μm size range (estimation). Smaller particles such as bacteria may also be ingested. Uptake of DOC (such as amino acids) is likely, based on data from Scleractinian corals.
