Family Dendrophylliidae

Cup Corals

Cup corals are non-reef building species that inhabit shaded vertical surface and caverns down to great depths.  There are only two species likely to be seen while scuba diving in Hawaii.  They rely upon capturing zooplankton as food and extend beautiful translucent tentacles at night.  Cup corals are also found in very cold water throughout the world.

All coral skeletons illustrated are from scientific collections taken prior to 1998.
