Rhinopias aphanes is a Scorpionfish from the Western Pacific. It occasionally makes its way into the aquarium trade. It grows to a length of 25 centimetres (9.8 in) TL. Information on this species is based on three specimens of Rhinopias aphanes that were collected from Australian waters and compared to a previously recorded Holotype. The distribution of this species seems to be restricted the coral reefs of the Western Pacific. This species is thought to be a benthic fish, resting on the sea floor. It has been observed that they are very reluctant to leave the bottom and rarely swim. Rather, they locomote using walking and hopping-like movements using their pelvic and pectoral fins. The prey of Rhinopias aphanes consists of small fish.
