brittle star awaiting identification* updated Jan 09 Where seen? This little brittle star with bristley arms is commonly encountered on our Northern shores, in muddy silty areas among seagrasses and seaweeds. Also among coral rubble. More active at night, it is fast moving and highly sensitive to light, scurrying swiftly into hiding. Features: Disk diameter less than 1cm, arms about 2-5cm long. Central disk thick and distinctly star-shaped. Along the sides of the arms are long cylindrical blunt spines that are held in such a way that the arm resembles a bottlebrush. In some, the arms have a pattern of hexagons, in others a pair of narrow parallel lines. |
