Ookhokho basendulo bezinhlobo zokuphila zamanje babebizwa ngokuthi ama-cladoselachies.
Ushaka we-cladoselachia ongasekho
Isidalwa esishiye umbhalo, njengoba kungahlulelwa ngosayizi wethrekhi nezinye izibonakaliso, kuvele ukuthi besingabi sikhulu ngokukhethekile, sinobude obungamamitha amabili kuphela. Kodwa-ke, ngejubane lokuhamba kwezinhlobo zesimanje, kusobala ukuthi isidalwa esifana nalesi semvelo sasisezingeni eliphansi.
Inezimpiko ezimbili zomgogodla, ezihlotshiswe ngemisipha, umsila ufana kakhulu nesizukulwane samanje soshaka. Amehlo ezidalwa zasendulo ayemakhulu futhi ebukhali. Kubonakala sengathi babedla izigaxa zamanzi kuphela. Izidalwa ezinkulu zabalwa phakathi kwezitha nezimbangi zazo ezimbi kakhulu.
Ushaka omncane
Oshaka bezingane kuphela engxenyeni yesibili yekhulu elidlule batholakala emanzini oLwandle lweCaribbean. Kwathi kuphela amashumi amabili eminyaka kutholakale lolu hlobo lukashaka, bathola igama labo: i-etmopterus perry. Izidalwa zemifino zanikezwa igama elifanayo ukuhlonipha usosayensi odumile ozifundayo.
Futhi kuze kube namuhla kusuka izinhlobo zoshaka ezikhona azikho izilwane ezincane ezitholakele emhlabeni. Ubude balezi zingane abweqi ku-17 cm, kanti abesifazane bancane ngisho nangaphansi. Bangabomndeni woshaka abasolwandle olujulile, futhi ubukhulu bezidalwa ezinjalo abuphenduki bube ngaphezu kwama-90 cm.
Ushaka omncane
I-Etmopterus perry, ehlala ekujuleni okukhulu kwamanzi olwandle, ngesizathu esifanayo, ifundwe kancane kakhulu. Ziyaziwa njenge-ovoviviparous. Umzimba wabo uvulekile, imvunulo yabo imnyama nsundu, imakwe imivimbo esiswini nasemhlane. Amehlo ezingane anempahla yokukhipha ukukhanya okuluhlaza okotshani olwandle.
Ushaka wamanzi ahlanzekile
Kuchaza izinhlobo ezahlukene zoshaka, kungaba kuhle ukungabanaki abantu abahlala emanzini angenasawoti bakule ndawo engaphansi. Sekuvele kushiwo ukuthi lezi zidliwayo zasemanzini, noma zihlala njalo olwandle nasolwandle, zivame ukuvakasha, zivakashele amachibi, amatheku nemifula, zibhukuda lapho isikhashana nje, zichitha ingxenye enkulu yempilo yazo endaweni enosawoti. Isibonelo esivelele salokhu kwakuyi-bull shark.
Kepha isayensi iyazi futhi izinhlobo ezinjalo ziyazalwa, zihlala njalo futhi zife emanzini ahlanzekile. Yize lokhu kungavamile. Ezwenikazi laseMelika, kunendawo eyodwa kuphela lapho oshaka abanjalo bahlala khona. Leli chibi elikhulu eNicaragua, elisendaweni enegama elifanayo, hhayi kude namanzi asePacific.
Ushaka wamanzi ahlanzekile
Lezi zidlakela ziyingozi kakhulu. Zikhula zifike ku-3 m bese zihlasela izinja nabantu. Esikhathini esithile esidlule, abantu bendawo, amaNdiya, babevame ukungcwaba abantu besizwe sakubo emanzini echibi, ngaleyo ndlela banikeze abafileyo ukuba babadle izilwane ezidlayo.
Oshaka bamanzi angenasawoti bayatholakala nase-Australia nasezingxenyeni ezithile ze-Asia. Zihlukaniswa ngekhanda elibanzi, umzimba oqinile kanye ne-snout emfushane. Isizinda sabo esingenhla simpunga-luhlaza okwesibhakabhaka; phansi, njengezihlobo eziningi, kukhanya kakhulu.

Abamele lo mndeni babizwa nangokuthi i-sawtooth, yona uqobo ekhuluma ngengozi yabo njengezilwane ezidla ezinye. Lokhu kufaka phakathi ushaka omnyama omnyama.
Lesi sidalwa sincane ngosayizi (abantu abakhiwe bafinyelela kwenye indawo kubude bemitha), kepha ngenxa yalesi sizathu bahamba ngokumangalisayo. Oshaka abamnyama abamnyama bangabantu bezinto zikasawoti ezizingela ama-cephalopods, kepha ikakhulukazi izinhlanzi ezinamathambo.
Ushaka omnyama omnyama
Bazingela ama-anchovies, ama-sea bass nezinye izinhlanzi zalolu hlobo, kanye ne-squid ne-octopus. Lab 'oshaka bashesha ngendlela yokuthi bakwazi kalula ukuhlwitha isidlo sasemini ngobuhlakani ezihlotsheni zabo ezinkulu. Kodwa-ke, nazo zingaba izisulu zazo.
Umzimba wezidalwa ezichazwe, njengamalungu amaningi omndeni wazo, uhlalisiwe. Isimpondo sawo siyisiyingi futhi sihlangene. Amazinyo abo athuthukile ajingiwe, okusiza oshaka abanamakhala amnyama ukuhlaba inyama yabo.
Lezi zinsimbi ezibukhali emlonyeni zisesimo sikanxantathu oblique. Izikali zePlakoid zesakhiwo esikhethekile, isici esengeziwe sezinhlobo zezinsalela, zimboza umzimba walaba bameleli bezilwane zasolwandle.
Umbala wabo ungahlulelwa ngegama lomndeni. Kwesinye isikhathi umbala wazo uphenduka ungabi mpunga uqobo, kodwa ugqama ngombala onsundu noma oluhlaza okotshani. Isizathu segama lezinhlobo zalezi zidalwa kwakuyimininingwane ephawulekayo - indawo emnyama emphethweni wephunga. Kepha lolu phawu luvamise ukuhlobisa ukubonakala koshaka abancane kuphela.
Izilo ezinjalo zitholakala ngasogwini lwezwekazi laseMelika, njengomthetho, ezihlala emanzini anosawoti zigeza ingxenye yaso esempumalanga. Umndeni woshaka abampunga uzuze idumela labazimuzimuzimu, kepha yilolu hlobo oluvame ukungabahlaseli abantu. Kodwa-ke, ochwepheshe baseluleka ukuthi baziqaphele kakhulu izilwane eziyingozi kangaka. Uma ukhombisa ulaka, lapho-ke ungangena enkingeni kalula.
Ushaka weWhitetip
Izidalwa ezinjalo zimelela nomndeni woshaka abampunga, kepha zibusa ngaphezu kwezinye izinhlobo. I-Whitetip shark yisilwane esinamandla esidla ezinye izinto esizoba yingozi ukwedlula imiqolo ekhaleni elimnyama. Unolaka ngokweqile, futhi emzabalazweni wokuncintisana wezilwane, uvame ukunqoba abalingani bakhe emndenini.
Ngosayizi, abamele lolu hlobo bayakwazi ukufinyelela kumamitha amathathu ubude, ngakho-ke oshaka abancane bangawela kalula enanini lezisulu zabahlukumezi be-whitetip, uma bengaqapheli.
