Comb Sea Star, Sand sifting starfish

Astropecten polyacanthus


The upper surface of the comb star is a dark purplish colour, while the underside is orange. On the upper surface paxillae, (Latin, "little stakes") little pillars with flattened summits, are cream, grey or brown, the colours sometimes making a chevron pattern. Along the edges of the five arms there is a fringe of long, sharp marginal spines, usually with brown bases and pale tips. The arms are fairly broad and have a maximum length of 9 centimetres (3.5 in). The tube feet are pointed rather than having suckers, an arrangement that is more suitable for digging. Source:
