Also known as Crinoid, Feather Star Criniod, Feather Starfish, Sea Lily, Storked Sea Lily.
Found singly or in groups, on high coral outcrops and ledges, with exposed dead and live corals, in current prone areas of the reef. At night, free swimming hunting for their planktonic food.
They feed nocturnally on plankton.
Length - 20cm
Depth - 0-50m
Widespread Indo-West Pacific
Feather stars are usually found curled up during the day, but at night they extend their feathery arms to catch plankton in the currents.
They float, crawl, roll, walk or even swim through the current to different locations.
Some small animals like clingfish and crustaceans can be found in the arms of feathers stars.
Feather stars have both their mouth and anus on the upper surface.
Very much like sea stars if their arms are damaged they can regenerate at will. (edit) Ref: https://en.wikipedia.org/wiki/Oxycomanthus_bennetti
