Duncanopsammia is a genus of marine large polyp stony coral (LPS). It is monotypic, meaning it has only one species, Duncanopsammia axifuga, the whisker coral or "Duncan". The growth habit of the coral is branched, the polyps are round and have distinct tentacles. In shape they therefore resemble Tubastrea corals and other non-photosynthetic coral species, which occasionally leads to confusion.
However, Duncanopsammia has zooxanthellae and can feed on light. However, supplemental feeding with LPS pellets, zooplankton or phytoplankton is still readily accepted. It is mainly found in Australia and the South China Sea at depths of up to 30m.
