This is a NEW RECORD for Queensland and the Mooloolah River, found from under a rock.
Previously known from Tasmania and New South Wales and thought of as Onchidoris depressa which is from the Atlantic Ocean
and lays an egg mass with 2 rows per whorl. The animals from Australia lay a single row and must be Onchidoris maugeansis.
