Ushaka omhlophe

Ushaka omhlophe

Iningi labantu liyamesaba ushaka omkhulu omhlophe yize ejwayele ukungabahlaseli. Ochwepheshe boshaka bathi inyama yethu ayithandeki neze. Ubufakazi balokhu ukuthi oshaka baluma ababhukudi kanye kuphela futhi abaphindi. Lokho kuluma ukunambitha inyama kamuva abangayinambitha ngoba abayithandi. Kucatshangwa ukuthi ushaka unezinzwa eziphakeme kakhulu, yize udida abantu nezinye izilwane eziyingxenye yokudla kwabo, njengezimpawu.

Kule ndatshana sizobheka ngokujulile ushaka omkhulu omhlophe. Sizofunda nge-biology yabo, ukusatshalaliswa, ukudla kanye nendlela yokuphila. Ngabe ufuna ukwazi konke ngalesi silwane esidume umhlaba wonke?

Izici eziyinhloko

Usayizi nesikhumba

Izici eziyinhloko

Ngenhlanhla, kubantu abahlaselwa yilesi silwane, imvamisa akubizi impilo yabo. Lapho ukulunywa kukashaka kuba ukopha okunzima ukuyeka kulapho kuba yingozi kakhulu, kuze kube sezingeni lokufa. Kulezi zimo, abaseduze kwesisulu kumele baqhubeke ngokushesha. Igazi elichitheka emanzini lingakhanga kwabanye oshaka.

Futhi ngukuthi ushaka ubhekwa njengesilwane esikhulu esidla ulwandle. Itholakala olwandle oluningi emhlabeni. Zijwayele ukubizwa nge- "Great White Shark" ngoba aziyeki ukukhula kukho konke ukuphila kwazo. Isilwane esidala, siyakuba sikhulu ngosayizi. Abesifazane bakhulu kunabesilisa. Umuntu omdala angakwazi ukukala ngokuphelele phakathi kwamamitha ama-4 kuye kwayi-5 ubude futhi abe nesisindo esiphakathi kuka-680 no-1100 kilos. Lezi zilinganiso zenza kube yingozi ukuzingela.

Amazinyo abo anamandla abanzi futhi angunxantathu futhi bawasebenzisela ukudwengula inyamazane yabo nokudla inyama. Ngenxa yabo bangakwazi ukunamathela kubo baze babasike. Lapho amazinyo ephuma noma ehlukana phakathi, kufakwa amanye amasha, njengoba enemigqa emibili kuya kwemithathu yamazinyo akhula ngokuqhubekayo.

Isikhumba sazo simahhadla futhi sakhiwe ngezikali ezimise okwegazi. Lezi zikala zibizwa ngokuthi ama-dermal denticles.

Uhlelo lwezinzwa nephunga

Isistimu yezinzwa yoshaka omhlophe

Ngokuqondene nesistimu yezinzwa, banayo kakhulu, kuze kufike ezingeni lokukwazi ukubona ukudlidlizela emanzini amamitha ambalwa ukusuka lapho. Ngenxa yaleli zinga lokubona, bangaziqondisa phakathi kokudlidlizela kwesisulu esisuselwe kubo futhi bazingele.

Umuzwa wokuhogela nawo usuthuthukile impela. Njengesidlo esidla inyama, ikwazi ukuhogela amaconsi egazi amaningana ukusuka ebangeni eliqhele ngamanani amanzi asizungezile. Lapho kunegazi, ulaka lukashaka luyanda.

Iqiniso lokuthi ubizwa ngo-shark omhlophe kungenxa yokuthi akuzange kutholakale izinhlobo ezivame kakhulu, kepha zingama-albino.

Ibanga nendawo yokuhlala

Indawo nendawo okusatshalaliswa kuyo

Lesi silwane sisatshalaliswa kabanzi. Bayakwazi ukuhlala emanzini abandayo nasendaweni eshisayo. Imethabolism ethuthukile ibavumela ukuthi bahlale befudumele emanzini, yize bengeke bakwazi ukumelana namazinga okushisa aphezulu.

Indawo enkulu kashaka omhlophe isemanzini angajulile futhi aseduze nasogwini. Yilapho inani elikhulu lezinhlobo zasolwandle ligxila khona. Ngakho-ke, zonke lezi zidalwa zisebenza njengokudla kukashaka. Ngokuhlukile, abanye oshaka batholakale ekujuleni kwamamitha ayi-1875.

Ezinye izindawo nezifunda lapho le nhlanzi ihlala khona: amanzi eGulf of Mexico, Florida nasempumalanga ye-United States, Cuba, Hawaii, Australia, New Zealand, Japan, South Africa, England naseCape Verde Islands naseCanary Islands.

Ukudla koshaka omhlophe

Ukudla

Lapho lesi silwane sincane, sidla kakhulu ama-squid, imisebe nabanye oshaka abancane. Njengoba zikhula futhi zikhula zikwazi ukushwabadela izimvu zamanzi, amahlengethwa, amabhubesi olwandle, izimvu zamanzi zezindlovu, izimfudu ngisho nezidumbu zemikhomo.

Indlela ayisebenzisayo ukuzingela inyamazane imayelana "nokulandela." Ifihla ngaphansi kwesisulu ukuze ibhukude ibheke phezulu futhi iyimangaze ngaphandle kokukwazi ukusabela nokuzivikela. Ngenxa yokulunywa okukhulu kukashaka omhlophe, isisulu siyafa ngokulahleka kwegazi noma ukunqunywa ikhanda. Izengezo ezibalulekile ezinjengamaphiko nazo zingaphulwa.

Ukuzala

Ukuzala

Oshaka abamhlophe besilisa bafinyelela ekuvuthweni ngokocansi cishe eminyakeni eyishumi. Abesifazane, ngakolunye uhlangothi, bathatha iminyaka ephakathi kuka-10 no-12. Lesi yisizathu esenza ukuthi abesifazane babe bankulu. Njengoba ukuvuthwa kwabo ngokocansi kungemva kwesikhathi, bachitha isikhathi esiningi ekukhuleni komzimba.

Uma besesikhathini sokukhwelana banolaka kakhulu. Owesilisa uqala ukuluma insikazi ngesikhathi sokuhlangana kuze kube sezingeni lokulimaza. Okufanayo kuya ngezimfudu (isixhumanisi). Ngakho-ke, kujwayelekile ukubona abesifazane abanezibazi ikakhulukazi emaphikweni. Zizala emanzini apholile ngenkathi yasentwasahlobo-ehlobo.

Lolu hlobo lwe-ovoviviparous, ngoba amaqanda, avame ukuba mabili kuya kwayishumi, ahlala esibelethweni izinyanga eziyi-12 aze agcine echamusele. Yize kungakasungulwa kahle, amacala we-intrauterine cannibalism angenzeka, ngoba imidlwane ebuthakathaka ingasebenza njengokudla kwamakhulu.

Lapho zizalwa zingaphezu kwemitha ubude futhi ziyaqhela kunina. Ezimweni eziningi, umama ushwabadela izingane zakhe. Akazenzi njengomama uqobo, ngoba akavikeli futhi akabalandeli. Kusukela ekuzalweni bazimele ngokuphelele.

Isikhathi sokuphila siphakathi kweminyaka eyi-15 nengama-30.

Indoda noshaka omhlophe

Indoda noshaka omhlophe

Le nhlanzi yesatshwa kakhulu ngumuntu, ngoba iveze ukuhlaselwa okuningi kubantu abenza ukuntweza, ukudilika emanzini, ukuhamba ngesikebhe noma ukubhukuda. Balinganiselwa ku-311 abantu abahlaselwe emhlabeni jikelele.

Yize umuntu oyedwa engakwazi ukulwa noshaka omkhulu omhlophe, ukudoba kwezemidlalo kunciphisa inani labo. Abanye babazingela bephikisana nokuthi bamele ingozi kubagezi, okuthinta ezokuvakasha emazweni athile.

Futhi wena, ucabanga ukuthi ushaka omhlophe uyingozi enkulu kubantu?
