Japanese seastar, North Pacific sea star
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.
An introduced pest not a target species, these seastars are often observed by fishers. There are sometimes caught in pots or nets or accidentally on rod and line in the Derwent estuary. Voracious predators of native bivalves, they will eat any animal matter available to them including discarded bait and fish waste. The Northern Pacific seastar is a declared noxious species and it is illegal to possess them on state waters. It is important to know how to distinguish this pest species from native species before you remove any seastars from the water. See the native eleven armed and granular seastars listed in this app.
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.
