In science there is no distinct dividing line between soft corals and gorgonians. \nTriton Bay, Indonesia \n3°54'52.062 S 134°7'21.384 E at 10m depth

Indian Feather Duster Worm Sabellastarte spectabilis occurs in the tropical Indo-Pacific Ocean from the Arabian Sea to Hawaii in intertidal and subtidal reefs in a depth range from 3-30m. It is quite a large species, with a tube up to 30cm and a single crown of about 10cm in diameter, feeding by filtering plankton and organic particles from the water column. \nAs a defence mechanism, these creatures are able to quickly retreat into their tubes, when disturbed by potential predators. It may come as a surprise, but Sabellastarte has eyes! \nCrowns of this species often have a banded pattern in a variety of colors including browns, red, white and yellow. Yellow  like this specimen  is the rarest color for this species. \nTengah Island, Indonesia, 5°8'44.496 S 132°0'46.254 E at 8m depth by night
