Kuti chiitiko chekukwirana chiitike chinofanirwa kuitiswa mumvura isina kudzika. Mukuradzika kwega kwega ivo vanokwanisa kugadzira pakati pevane makumi maviri nerimwe kusvika makumi maviri nemasere vadiki. Kubva panguva iyo vechidiki vanoparadzaniswa naamai vavo vanofanirwa kuve vakazvimiririra zvachose. Kudzidza kufura wega uri wakakosha zvakanyanya kana iwe uchida kukura uye kurarama mumamiriro akanaka. Hazvishamise kuti kwemazuva mashoma ekutanga mushure mekuzvarwa vachiona hunhu hwekudyara kudzima nzara yavo nekukura kweropa.
Mukoti shark kuziva
Pakati pekuda kuziva kune shark iyi, tinogona kuona kuti, kunyange iri mhuka ine runyararo uye isingakuvadzi, inzvimbo yakanyanya. Iyo inokwanisa kugara mune imwe nharaunda kweanosvika makore mana. Dzimwe nguva zvinogona kuoneka kuita zvechisimba kune mamwe marudzi kana kunyangwe vamwe vanhu vanosvika kunharaunda yavanogara. Kana achinge amuda, anozvarwa, kana akasatama kubva kuna amai vake ega mukati menguva yakareba yevhiki, anogona kunge ari iye mai vacho vanozopedzisira vachidya.
Ivo vanokwanisa kunzwa ropa reimwe mhuka kupfuura makiromita mashanu kure. Zvichienderana nerudzi rwemvura yegungwa panguva iyoyo, chinhambwe ichi chinogona kutonyanya kukura.
Kuve isiri mhando isingakuvadzi kuvanhu, inoiswa muchimiro sekutyisidzirwa. Huwandu hwehaki hunovhimwa zvisiri pamutemo nekuda kwekusviba uku kwakakura. Mhosva yakakosha yakaitika musi waChikumi 15, 2009 yakakonzera masangano anodzivirira kodzero dzemhuka kuvhiringidzwa nawo Mune ino kesi, kwaive nekutakura kwemakumi maviri emidziyo yemamita gumi nemaviri kureba imwe neimwe yakasiya chiteshi cheYucatan ichienda kuSpain.
