Iyo yakasarudzika indigo coloration kumashure inoita musiyano wakanaka kune yakajeka grey pazasi pezasi. Pamativi ivo vane yakajeka bhuruu ruvara.
Maziso akakurisa uye muromo wayo une chimiro chakafanana. Meno aro akasunga micheto kuti zvirinani kugaya chikafu. Nepo mazino epachikamu chepamusoro aine mativi matatu uye akasungirirwa, iwo ari mushaya yepasi ane yakatwasuka uye yakatetepa chimiro. Zino rega rega rinotsiviwa mukati memazuva ari pakati pe8 ne15.
Macheka avo emapectoral akareba kwenguva refu kana tikachienzanisa neaya mamwe akawanda marudzi eshark. Yechipiri dorsal fin idiki pane yekutanga. Kana iri muswe wayo, hwakareba, izvo zvinoita kuti uve nehunyanzvi hwekushambira. Ivo vanokwanisa kushambira nekumhanyisa kukuru uye, vane hunyanzvi hwakakura uye mutete mutete, vanove vanotyisa zvikara.
Kugovera uye pekugara

Kuve kwehukuru hwakakura uye huremu, zvinotora nguva yakareba kuti vasvike pakukura.
Aya mashark ane tsika yekufambidzana iyo inosanganisira kurumwa kubva kuchirume kusvika kuchikadzi pakati pekutanga uye chechipiri chekumapendero. Hadzi haigashi kukuvara sezvo ganda rake rakapetwa katatu kupfuura iro rechirume. Aya ndiwo marongedzero anoita murume mukadzi nekupinza mbichana mukati mekuvhura kweurogenital. Inoendesa urume uye mushure mekubata shark mbiri dzakaparadzana. Vechidiki vanokura mukati mehomwe yeganda. Kubata kunotora pakati pemwedzi mipfumbamwe ne9. Kana vana vadiki vazvarwa, vanongove vakareba masendimita makumi matatu nemasere. Havana kuchengetwa nevabereki. Kana vangozvarwa vanozviparadzanisa uye vanokura vega.
