El tremielga hove kana torpedo hove, inonzi futi tremielgas kana tremielgas, imhando dzoga uye dzinoshambira dzakaipa dzinowanzo kuwanikwa dzichivigwa zvakakwana mujecha kana mumatope, kusiya chete maziso nemipendero zvichioneka. Ihove iyi inoratidzirwa nehunhu hwayo hwekugara uye nedhisiki yaro ine mativi akakomberedzwa ayo anokonzerwa nekusanganiswa kwemuviri nemapeche epectoral.
Muviri we iyo tremielga inoshungurudzika zvakanyanya, uye pectoral fins, ayo akakomberedzwa, akasanganiswa pamwe chete nawo, ayo avanoumba zvishoma akapetwa dhisiki mune yayo yekumberi chimiro.
Mheto dzechiuno, zvakare dzakatenderedzwa, dzinoonekwa pazasi peketari, uye dzakanamatira kune yemukati hafu yemuswe, iyo inopera neyakagadzirwa zvakanaka caudal fin. Pamutsetse wepakati, muswe une zvimbi zviviri zvemashure. Iyo maziso madiki kwazvo asi ane mukurumbira, ichikubvumidza iwe kuti utarise zvakakukomberedza nemuviri wako wakafukidzwa zvakakwana mune sediment.
Iyo hafu arched muromo inoratidza mazino madiki akarongedzwa mumitsara. Ganda rakatsetseka, uye kumusana kune nhengo dzemagetsi idzo inoburitsa kuvhunduka kwakasimba apo tremielga painonzwa kunetswa, uku kubuda, kunyange kuchinetsa, hakuna njodzi kumunhu. Mazai anowanzoitika anosvika pakati pe45 ne80 volts, kunyangwe mune mamwe mamiriro uye mune yakakura kwazvo mienzaniso vanogona kusvika 220 volts. Kunyangwe vacheche vachangozvarwa vanokwanisa kuburitsa kutyisa kweanenge mana ma volts.
Vanogona kuburitsa magetsi magetsi pamadiro nekutenda kunhengo mbiri dzakaumbwa seitsvo uye neruvara rwechiedza dzinodaidzwa kuti "electroplasts". Nhengo idzi dziri kumberi kwediski, kudivi rega remusoro.
Iyo tremielga imhando yemhando dzeusiku tsika uye inodya benthic zvipenyu. Iyo ovoviviparous uye kubata kunotora kwemwedzi gumi uye Inogona kutakura mazai ari pakati pe5 kusvika 32, zvichienderana nesaizi yechikadzi.
