Identifying features

​Adults are predominately yellow-brown whilst juveniles are yellow with purple tinges towards the arm tips and central disc. They are very spiny and normally have five arms. Unlike the native granular and eleven-armed seastars, they have pointed, upward-turned tips.


Found on intertidal, estuarine and reef areas and around wharves and jetties in south eastern Tasmania, predominantly in the Derwent estuary. Introduced from the northern Pacific via larvae in ballast water of tankers discharged into the Derwent Estuary.
