large colourful fast moving sea star is sometimes encountered on our
Northern shores. In sandy or silty shores, near seagrasses. According to Marsh and Fromont, it is moderately common on silty sand, weed and sand and shells in Australia.

long, tapered to a sharp tip. Along the sides of the arms are large
marginal plates and stout flat long spines. These spines resemble
the teeth of a comb and members of this family are sometimes called
Comb sea stars. The spines are white, usually tinged a pale orange
at the base. Upperside a light
blue background with orange or darker blue stripes shading to orange
near the tips. The arm tips are black. Sometimes with darker blue
bands near the arm tips. Underside pale without markings. Tubefeet translucent with pointed tips.
What does it eat? According to Marsh and Fromont, it eats small clams and snails, which are swallowed whole. |
