 Like other members of its family , the onefin electric ray can defend itself with a strong electric shock produced from a pair of kidney @-@ shaped electric organs beside its head . It feeds mainly on polychaete worms , and likely gives birth to live young . The International Union for Conservation of Nature ( IUCN ) presently lacks enough information to assess the conservation status of this species . It is often caught incidentally by bottom trawl fisheries off South Africa , and may also be impacted by pollution from coastal development .
