Elasmobranchii (sharks and rays) > Torpediniformes (Electric rays) > Narkidae (Sleeper rays)
Etymology: Electrolux: Name refers to the well-developed electrogenic properties of this ray, the discovery of which sheds light (Latin 'lux') on the rich and poorly known fish diversity of the Western Indian Ocean.; addisoni: Named for Mark Addison, BlueWilderness dive charters of Widenham, KwaZulu-Natal..

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 52.0 cm TL male/unsexed; (Ref. 75572); max. published weight: 1.8 kg (Ref. 75572)

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).

Estimates based on models

Preferred temperature (Ref. 123201): 23.7 - 24.1, mean 23.8 °C (based on 6 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
