| Found in warm-temperate or subtropical waters approximately 310 km of coastline with very narrow continental shelf (10-36 km wide to the 200 m isobath), however, the few sightings were all inside the 50 m isobath; on reefs with sandy or gravelly areas from close inshore to less than 50 m depth, including patches of appropriate habitat on inshore and offshore rocky banks and reefs. Apparently an infauna or meiofauna feeder, feeding on polychaete worms (including a tube-worm) and at least one small shrimp-like crustacean (Ref. 75572). |

Type locality, reef off Manaba Beach near Margate, southern KwaZulu-Natal; SAIAB 78777 (holotype of Electrolux addisoni, 51.5 cm TL, 30.5 cm disc width, adult male). Recorded along an approximately 310 km. strip of coastline from Coffee Bay, Eastern Cape Province, to just north of Durban, KwaZulu-Natal inside the 50 m isobath. This conspicuous, active ray is known only from a few diver records from reefs reported over approximately two decades and its conservation status needs to be critically assessed (Ref. 75572). |
