Duncanopsammia

Duncanopsammia is a monotypic genus of stony corals. It is represented by the single species, Duncanopsammia axifuga, commonly called whisker coral, duncanops coral, or simply duncan coral. Individual polyps are fairly large with round skeletal bases (corallites) 10–14 millimetres (0.39–0.55 in) in diameter and larger central discs from which multiple tentacles radiate; the polyps form a structure branching at irregular intervals to form a large colony.
