Long-arm Feather Star

Found singly, or in colonies, attached to exposed coral heads during the day. At night they can be found free swimming, hunting for food.
They feed nocturnally on plankton.

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.
