The pulsing sinularia is a soft coral and unlike a common sinularia, the pulsing sinularia is not found in many stores or aquariums. What makes this coral stand out is the pulsing action that it undertakes when it filter feeds. This video shows some of the regular pulsing action but the corals are known to make much more dramatic pulsing. It is a rare thing to witness let alone capture on video.
