Description

Also known as Crinoid, Feather Star Criniod, Feather Starfish, Sea Lily, Storked Sea Lily.

Found singly or in groups during the day anchored to gorgonians, high coral outcrops and ledges in current prone areas of coral and rocky reefs. This feather star has between 75-125arms and is highly variable in colour.
They nocturnally feed on zooplankton.
Length - 20cm
Depth - 0-90m
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. Ref: https://www.sealifebase.ca/summary/Clarkcomanthus-alternans.html
