Iri zita rinopihwa nekuda kwekufanana kune iyo tomu yemaziso ayo iine neiyi feline. Iine muviri wakareba uye wakanaka usina zviyero uye nemucheka wakafanana neiya wesandpaper. Apa ndipo panobva zita rakajairika lime. Iyo inongova nemapfumo maviri ekumashure, ichiiita iyo yakasarudzika mhando dzeshark. Musoro wake une chimwe chimiro chakati. Iyo ine hunhu hwakasiyana iyo inoratidzika kunge trunk uye yakafanana nemakomba mumhino.
Iyo seti yekati shark inomira kuve iyo ine iwo ane pateni pane yavo ganda.

Inogona kushambira pakadzika kusvika pamamita 2000.
Zvokudya
Iyi shark inodyisa kunyanya pakudya kwemhuka diki dzisina nyama dzinowanikwa mukati megungwa. Kudya kwayo kunodya uye kunoda huwandu hwakawanda hwenyama. Inogona zvakare kupinza, kunyangwe muhuwandu hushoma, dzimwe dziine nzvimbo dzechinhu chakareruka chekugona kubatanidza zvimwe zvekuvaka zvinoda kuti zvikwanise kukura mumamiriro ezvinhu.
Maererano nenyanzvi dzezvipenyu zvemugungwa dzinoona zvinodyiwa neshark, dzinoti shark iyi inodya dzimwe hove diki nekuda kwekukura kwayo. Uyu ndiwo musiyano mukuru unoidzivirira kuti isakwanise kuvhima dzimwe mhuka hombe. Mukupesana, hazvireve kuti kudya kwavo kushoma sezvo kune kwakasiyana siyana de peces madiki uye asina vertebrates munzvimbo dzinogara shark idzi.
