This sea star is a carnivore and feeds on molluscs, which it catches with its arms and then takes to the mouth. The prey is then trapped by the long, moving prickles around the mouth cavity
This species is active and easy to find especially in the late afternoon, but sometimes it is possible to find it during the day or during the night.
This species lives only in the Mediterranean Sea and it prefers sandy seabed near meadows of the seagrass Cymodocea nodosa.
