Akungabazeki, wonke umuntu okungenani kanye empilweni yakhe waphupha ngokusungula umshini wesikhathi nokuvakashela okwedlule okude noma ukungena ezweni lesikhathi esizayo.
Futhi labo abanesithakazelo esikhulu kuyo yonke into ephathelene nezilwane ngenjabulo enkulu, mhlawumbe bangena ezikhathini zomlando wasendulo futhi babheka zonke izenzakalo zemvelo, umhlaba wezilwane kanye nezwe lezitshalo nangaphambi kwesikhathi lapho konke okukhona kungazange kuguqulwe kuze kube degree njengamanje.
Kwazi bani, mhlawumbe singamangala ngama-dinosaurs. Ngempela, emhlabeni ongaphansi kwamanzi akukho okuncane okuthakazelisayo, okuthakazelisayo nokungajwayelekile kunasemhlabeni.
Esinye salezi zilangazelelo yinyoka yasemanzini, ehamba ekujuleni kolwandle ngokunyakaza kwayo okubushelelezi, okumangazayo, okuheha iso ngokungazibandakanyi futhi kungashiyi muntu engenandaba.
Kuyadabukisa ukuthi kumane nje akunangqondo ukubona lokhu. Noma kunjalo, uma ujwayela ushaka othosiwe okungukuthi, wonke amathuba okuhlangabezana nokwedlule komlando. Ngemuva kwakho konke, ungowozalo lwaleyo nyoka emangalisayo yasolwandle futhi engakashintshi iminyaka eyizigidi ezingama-95 ikhona.
Esikhathini sethu, uyinkosi yamanzi olwandle futhi ingenye yezinhlanzi ezithakazelisa kakhulu. Lokhu kuyinsalela ephilayo, insalela ngoba iminyaka eminingi ayikaze iguquke, iye yahlala injalo njengoba yayinjalo eminyakeni eminingi, eminingi edlule.
Izici nendawo okuhlala kuyo ushaka othosiwe
I-Frilled Shark ingenye yezinhlobo zezinhlanzi eziyivelakancane kakhulu ezihlala olwandle olujulile nesibonelo sangaphambi komlando. Ngenye indlela, ibizwa nangokuthi lukathayela.
U-Aul othosiwe uhlala ikakhulukazi ekujuleni okuqinile, okuphakathi kwamamitha ayi-600 kuye kwayi-1000. Lo shaka ofana nenyoka ukwazile ukusinda kuyo yonke inhlekelele yangesikhathi esidlule futhi kuze kube namuhla uzizwa engcono kakhulu.
Ukuphila okuchuma okunjalo kungenzeka ukuthi kwalethwe yile nhlanzi uqobo lwayo ngenxa yendlela yayo yokuphila yolwandle olujulile. Kunezitha ezimbalwa noma izimbangi zakhe ekujuleni kwamamitha ayi-600.
Umuntu wokuqala owazana nendoda enoshaka othosiwe kwenzeka ngo-1880. Isazi se-ichthyologist saseJalimane uLudwig Doderlein uqale wabona lesi simangaliso emanzini ageza iJapan. Wabelana ngezincazelo zakhe nangokubona kwakhe ngoshaka omuhle ayibonile.
Kepha njengoba lezi zincazelo zazinobuciko ngaphezu kwesayensi, bambalwa kuzo abazithatha ngokungathi sína. I-athikili yesayensi ebhalwe nguSamuel Garman, owayebuye abe yisazi se-ichthyologist esidumile, wanika abantu wonke amathuba okukholelwa ekubeni khona kwale nhlanzi. Kungemva kwalokhu kuphela lapho ushaka othosiwe aqala ukubhekwa njengenhlanzi ekhona ngempela yohlobo oluhlukile.
Avelaphi la magama angajwayelekile futhi amahle alolu shaka omangalisayo? Kulula. I-Frilled One yaqanjwa nge-placenta yayo emangalisayo futhi engavamile, enombala onsundu ngombala futhi ibukeka kakhulu njengengubo.
Ukhubazekile ngoba unamafolda amaningi emzimbeni wakhe omude. Ososayensi basikisela ukuthi amafolda anjalo awuhlobo lokugcinwa kwezilwane ezinkulu ezibekwa esiswini senhlanzi.
Kakade, le nhlanzi inekhono elimangalisayo futhi igwinya isisulu sayo ngokuphelele. Amazinyo akhe afana nezinaliti, agobele ngaphakathi emlonyeni wakhe futhi awakulungeli ukuchoboza noma ukuhlafuna ukudla.
Zibalelwa ku-300. Kepha banenzuzo eyodwa enkulu, ngosizo lwabo, ushaka angakwazi ukugcina isisulu sakhe emlonyeni wakhe futhi asivimbele ukuba sigqashuke, noma ngabe isisulu sishelelela kakhulu.
Osayizi bakashaka abathosiwe inokuncane. Insikazi yayo ingakhula ize ifike kumamitha amabili. Abesilisa bancane kancane - 1.5-1.7 wamamitha. Inhlanzi inomzimba onjenge-eel ohlangothini onekhanda elibanzi nelisicaba.
Vuliwe isithombe sikashaka othosiwe ngaphezu kwakho konke, amehlo akhe angenakuqhathaniswa adonsela ukunakwa. Mikhulu, iyisiyingi ngombala we-emerald omangalisayo. Zibenyezela ngokumangazayo ekujuleni okukhulu kuphela.
Yilapho lapho kudlula khona cishe yonke impilo kashaka othosiwe. Kunezikhathi lapho le nhlanzi emangalisayo inyukela phezulu emanzini. Lokhu kwenzeka ikakhulukazi ebusuku, lapho ushaka efuna ukudla.
Lesi silo sangaphambi komlando sihlala kamnandi emanzini afudumele olwandle i-Atlantic nePacific. Yilapho ungamthola khona. Ubuye wahlangana emanzini egeza iBrazil, Australia neNew Zealand, Norway. Indawo ehlala kuyo ayikacwaningwa ngokugcwele. Kungenzeka ukuthi itholakale emanzini ase-Arctic.
Ukugcina le nhlanzi ekujuleni okukhulu, isibindi sayo siyasiza, okuthi, ngaphezu kokuba sikhulu kakhulu, sigcwale ama-lipids amaningi, futhi lokhu kusiza ekugcineni umzimba kashaka ekujuleni kwamanzi ajulile ngaphandle kwezinkinga.
Imvelo nendlela yokuphila kukashaka othosiwe
Le nhlanzi iyisidalwa esinobuqili. Unobuhlakani obumangalisayo, ikakhulukazi maqondana nokuzingela. Kulokhu, ushaka usizwa ngamakhulu eminyaka wokuhlangenwe nakho kwakhe. Ukuze ihehe isisulu sayo, inhlanzi ilele ngokuthula nangokuthula emanzini, kanti umphetho wayo womsila uhlala olwandle.
Ngokushesha nje lapho kuvela khona ukudla koshaka eduzane, yenza umbani uye phambili ngomlomo ovuleke kakhulu futhi igwinye ngokuphelele isisulu esilingana nengxenye yobude baso.
Ngasikhathi sinye, izivalo zayo ziyavaleka, futhi kudaleke umfutho we-vacuum kushaka, odonsela ukudla ngqo emlonyeni wakhe. Ngasikhathi sinye, umsila wenhlanzi usiza ukuhamba ngokushesha, ngenxa yokuthi uyashesha njengenyoka.
Ukunyakaza okunjalo kuyiphikisa ngokuphelele inkolelo yokuthi ushaka unendlela yokuphila ehlala phansi. Le nhlanzi inolayini ovulekile ohlangothini. Lokhu kuvumela abemukeli bayo ukuba babambe ngokushesha futhi kude ibanga indlela yesidalwa esiphilayo.
Ukudla koshaka okuthosiwe
Ukuphila ngokukhethekile olwandle, ukuphakelwa koshaka othosiwe izakhamizi zakulokho kujula. Imvamisa, udla ama-cephalopods, ama-squid, izinhlanzi ezinamathambo ezansi nama-crustaceans. Kwesinye isikhathi uyakwazi ukuzitotosa ngoshaka omncane noma i-stingray.
Ukuzala kanye nesikhathi sokuphila
Kuncane kakhulu okwaziwayo ngokuthi le nhlanzi izala kanjani. Kepha njengoba ekujuleni lapho ushaka wamathambo uhlala khona, ukuguquguquka kokushisa kwangaphandle akubonakali nganoma iyiphi indlela, lapho-ke ososayensi banezizathu zokucabanga ukuthi ushaka othosiwe uzala unyaka wonke.
Abesifazane abanayo i-placenta, kepha babhekwa njenge-viviparous. Inani elijwayelekile lamaqanda awaphethe ezigabeni zakhe kusuka kumaqanda ama-2 kuye kwangama-15. Ukukhulelwa kukashaka othosiwe omude kunawo wonke ama-vertebrate. Insikazi ithwala amaqanda iminyaka engu-3.5.
Ngenyanga ngayinye yokukhulelwa, imibungu yakhe ikhula ngo-1.5 cm no-40-50 cm abantwana asebevele bezelwe, okuyinto owesifazane angayikhathaleli nhlobo. Oshaka abathosiwe baphila cishe iminyaka engama-25.
