Red comb star (Lat. Astropecten aranciacus). It lives on sandy, muddy or gravel bottoms at depths of 2–100 metres (7–300 ft). It has superomarginal plates equipped with 1 to 3 small spines and inferomarginal plates with long, pointed, strong, regularly arranged spines. The inferomarginal spines have reddish-orange colour at the base and yellowish or white colour towards the tip. It buries itself in the sand to shield parts of its body from the rays of the sun, especially the bottom surface which has no coloured pigment and is therefore particularly sensitive. It is a carnivore and feeds on molluscs, which it catches with its arms and then takes to the mouth.
