El intlanzi yokrebe, ekwabizwa ngegama layo lezenzululwazi iTorpedo Ocellata, yeyosapho lwe-stingray njengoko babelana ngezinye zeempawu ezifanayo zomzimba. Le ntlanzi inobume obukhetheke ngokukodwa, kuba umzimba wayo ungqukuva kwaye ungqindilili, ngelixa intloko ithe tyaba, amaphiko ayo emiphunga makhulu kwaye ajikeleze kwaye abekwe kwicala ngalinye lomzimba. Ngendlela efanayo, ayinayo i-anal fins, kwaye eyona nto inomdla kukuba inelungu kwicala ngalinye leediski ezinakho ukuvelisa ukuya kwi-200 volts yombane kwabo bayidlalayo.
Le nkqubo ukuveliswa kwee-volts zombane Ukongeza, ekubeni namandla, iluncedo kuba le ntlanzi iyisebenzisa ukuzondla kuba iyivumela ukuba ikhubaze amaxhoba kwaye izikhusele ngaxeshanye kwizilwanyana ezizama ukubahlasela.

Ngokubanzi, ezi ntlanzi zihlala kwiindawo apho ubunzulu bube yi-5 ukuya kuthi ga kwi-30 yeemitha, apho isanti kunye nentlabathi zihlala khona. Ezi zilwanyana zibonakaliswa ikakhulu ngokuzala amantshontsho azo endaweni yokubeka amaqanda, njengezinye iintlobo zemivumbo. Ukuba ufuna fumana lo mfo de pecesNgokuqhelekileyo zifumaneka kumanxweme oLwandlekazi lweAtlantic, kwiMeditera nakwezinye iindawo zelizwekazi laseAfrika. Khumbula ukuba ezi zilwanyana zitya inyama, kwaye ukutya kwazo kusekelwe ikakhulu kwizilwanyana ezingenamqolo, oononkala kunye nezinye iintlanzi ezincinci.
