Izinyo besikha kumphezulu wayo abe struychatost ezijikeleze (ukusika), nto leyo eyandisa kakhulu amandla ayo. Le umsonto elikhoyo ixesha elide, ngexesha phambili amazinyo esi silwanyana, alwe ukumelana kakhulu amanzi, kancinane iyajikeleza ngeenxa axis yayo. Ngenxa yoko, udonga hole ziguyiwe vee ezijikeleze kuyilwa kumphezulu wayo.

amadoda inqabile kakhulu ngamazinyo ezimbini, oko kwasekwa emazinyweni ezimbini. Ngokutsho manani, ezi zilwanyana zifumaneka enye abadala 500.

Okumangalisayo kukuba, nkqu isilwanyana bobabambi namhlanje, yaye ingakumbi uphondo kwayo, ihlale imfihlelo ukuba izazinzulu ehlabathini jikelele. Yena ayiqondakali kahle.

Ukuza kuthi ga ngoku, abaphengululi bakholelwa ukuba amazinyo narwhal ikuvumela ukuba uzive utshintsho kwamaqondo obushushu, uxinzelelo, lwee- ngamasuntswana emsebenzini.
