 They are animals, not plants, even if they look like them.

Adult hair stars are freely mobile and can move by crawling, running and some species can also swim. 

Most hair stars live as filter feeders in shallow marine zones with strong currents.

Due to their fragility, however, they avoid the intertidal zone.

They are shy of light and hide in caves and shady crevices during the day with their arms curled up.

At dusk, they leave their hiding place, climb to an elevated position and spread out their tentacles in a fan shape to catch plankton.
