The Scorpaenidae are a family of mostly marine fish that includes many of the world's most venomous species. As their name suggests, scorpionfish have a type of "sting" in the form of sharp spines coated with venomous mucus. The family is a large one, with hundreds of members. They are widespread in tropical and temperate seas, but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus Scorpaenichthys, which belong to a separate, though related, family, Cottidae.

Parapterois heterura, the blackfoot firefish, is a species of scorpionfish widely distributed on the southeastern coast of Africa as well as off Japan and in Indonesia where it is usually found in sheltered coastal bays with a soft bottom, such as fine sand or mud. It is found in depths ranging from 40 to 300 metres. This species is a sedentary fish and may even bury itself within the substrate. P. heterura flashes its brightly colored pectoral fins to startle predators and escape, but it may also use these fins to corner prey. This behavior has been demonstrated in other lionfish. This species can be found in the aquarium trade.

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.
