Shark! Vele ukhulume lelo gama futhi lingase likhumbule izithombe zesimo esivela ku- Jaws movie. Imibiko yakamuva yokuhlasela kuka-shark e -West Coast yaseFlorida mhlawumbe kusenza sikwazi ngisho nokubhekana nesimo esibi. Lokhu kungokwemvelo ngokuphelele, kodwa ochwepheshe bathi bangesabi.
Ngezinombolo
Okokuqala, ake sibheke inani lokuhlaselwa kuka-shark nokufa kwabantu eFlorida ngonyaka odlule . Ngokusho kwe-Florida Museum of Natural History sika-2015 World summary Summary Attack, ukuhlaselwa kuka-shark okungavunyelwe kwesikhatsi sonke isikhathi phakathi no-2015 kanye nokuhlaselwa kuka-98 emhlabeni wonke.
Njengoba sekuyisikhathi eside sekuyiminyaka eminyaka, iFlorida yaba nokuhlaselwa okungenakuvunywa emhlabeni wonke ngokuhlaselwa kuka-shark ngonyaka ka-2015. Lokhu kungaphezu kweziyisikhombisa ngaphezu kuka-2014, kodwa ngaphansi kwerekhodi eliphakeme lika-37 ngonyaka ka-2000.
Kokunye ukulinganisa, kwakukhona ukushona okuyisithupha emkhanyeni ngaphakathi kukahulumeni futhi akukho ukubulawa kwabakwa-shark. Ngisho izinyosi, izinyosi, nezinyoka zibulala abantu abaningi unyaka ngamunye kunezingwezi.
Imikhuba ye-Shark nomlando
Ama-shark ayekade ehamba cishe iminyaka eyizigidi ezingu-400. Mhlawumbe kuyinhlanganisela yezinzwa zabo ezinhle eziye zazisiza zisinde isikhathi eside kangaka. Umqondo wabo ozwakalayo uphefumula, futhi kucatshangwa ukuthi izingxenye ezimbili kwezintathu zobuchopho bazo zinikezelwa kulowo mqondo. Ezinye izinzwa zihlanganisa umbono, ukuzwa, ukunambitheka, ukudlidliza, kanye nokubona komzimba. I-Electro-perception isho ukuthi bayakwazi ukuqonda ama-electronics - ngakho-ke qaphela ukuletha amakhamera olwandle noma kungadonsela oshaka.
Eqinisweni, uma kuziwa ngesidlo sakusika, ngokuvamile badla bodwa kodwa ngezinye izikhathi bakhangwa yisisulu lapho abanye bedla.
Yingaleso sikhathi lapho bezoqhwaba khona futhi beme (ngisho nomunye nomunye) bakha ukuthi yini eyaziwa ngokuthi i-frenzy yokudla.
Umbono wehoksi wokubona nokudlidliza usebenza kahle ngokuhlaselwa kuka-shark. Ngokuphazima kweso ukugeleza emanzini - njengokungathi lapho i-diver ijikela emanzini ajulile-izodonsela ukunakwa kweshaka endaweni.
Ushaka luvame ukuluma umcengezi we-snorkeler owawuhamba ngokuthula ngaphandle kokushayela. Kukholelwa ukuthi ukubonakala kwesibhamu se-snorkeler kubonakala njengokudla. Kunjalo nangezinkwebizi zokubhukuda nokugeleza emanzini. Kungenzeka kube yinto yokungaziphathi kahle, lapho isikhumba siphutha ngenhlanzi ye-bait. Okumangalisa ukuthi, oshaka abaningi besaba ama-bubbles ayenziwe ngabanye futhi ngeke bawele ngaphezu kwe-diver ngenxa yalesi sizathu. Kodwa-ke, i-Tiger ne-White White ayinjalo - cishe ngenxa yokuthi usayizi wabo omkhulu ubenza bangabi nesibindi.
Nciphise Umngcipheko Wakho Wokuhlasela Kwe-Shark
Izingozi kufanele zinciphise ngaso sonke isikhathi kunokwenzeka kunoma yimuphi umsebenzi. IGeorge H. Burgess weFayili ye-International Shark Attack, iFlorida Museum of History History eYunivesithi yaseFlorida, iphakamisa amathiphu okunciphisa ingozi yokuhlasela kwe-shark.
- Hlala njalo ngamaqembu kusukela oshaka kungenzeka ukuthi bahlasele umuntu oyedwa.
- Ungalulazi kude kakhulu nasogwini.
- Gwema ukuhlala emanzini ngesikhathi sebumnyama noma amahora okushisa lapho oshaka besebenza kakhulu.
- Ungafaki amanzi uma uphepha noma uma unesilonda esivulekile.
- Ungagqoke ubucwebe obumhlophe.
- Gwema ukuthunga okungalingani kanye nezingubo ezinemibala ekhanyayo. Izikhwama zibona umehluko ikakhulukazi.
- Sebenzisa uqaphile uma amanzi evulekile.
- Ungafaki ngokweqile.
- Hamba kude nendawo emkhatsini we-sandbars noma eduze kwe-drop-offs, okuyizintandokazi ze-shark ezithandayo.
- Ungavumeli izilwane ezifuywayo emanzini ngenxa yokunyakaza kwazo okungaqondakali nokuphamba.
Futhi ekugcineni ...
- Ungangeni emanzini uma oshaka eyaziwa ukuthi ukhona futhi aphume emanzini uma kubonakala udoki.
Okubalulekile
Njalo qaphela lapho ubhukuda, u-snorkeling, noma udilika. Zonke oshaka ziyingozi futhi azibikezeli, kodwa ama-Bull no-Tiger sharks ikakhulukazi anonya. Uma ubhekene ne-shark, i-tap kanzima engqondweni ingabavimbela ekubheni. Ngeshwa, abantu abaningi abahlaselwe aboni u-shark ngaphambi kokuba bakhale, kodwa khumbula ukuthi amathuba okuxhumana no-shark noma okulunywayo amancane kakhulu - amanye athi asho 1 ku-11.5 million.
Eqinisweni, kungenzeka ukuthi ubomile kuqala (lezo zinombolo ziyi-1 kuphela kwezigidi ezingu-3.5).
