Frilled ushaka - izinhlanzi kwesikhathi Cretaceous, ngendlela engakholeki wahlala kuze kube yilolu suku. Ukuhlala olwandle, ngaphandle kwe-Arctic, emanzini ajulile, ungqimba phansi. Uma uyikha phezulu le cishe aliphumi, ngoba kakhulu ezingavamile. Amacala catch le ushaka ngasogwini aseYurophu naseNyakatho Afrika, eNingizimu Melika, California naseJapane.

le nhlanzi igama inikezwe i emphethweni engavamile imicu esehlanganise umbhangqwana wokuqala gill ukuvuleka. Basuke wajoyina ohlangothini ventral khumbuza izimpawulo noma entanyeni. lomzimba walo eside (cishe 2 m), snake-like, Browns. Izinsikazi zithé ukuba isikhathi eside kunaleso abesilisa. amehlo Okusaqanda ngaphandle nictitating ulwelwesi. ushaka komlando has a emgogodleni cartilaginous, hhayi ihlukaniswe amathambo. Fin caudal imelelwa blade eyodwa kuphela. amaphiko elikhulu ngokufanele eduze komunye nomunye kakhudlwana umsila.

Chlamydoselachus has oluvelele ngalo ingaphakathi ngomlomo ngokufanele i-ingxenye ekupheleni empumulweni, hhayi phansi, njengoba izinhlanzi yesimanje. Amazinyo ngalokwanele zifane umqhele, emihlanu-kwakubonisa, hook. namazinyo indawo engavamile: ngaphambili encane futhi bakhulise ezinkulu, engesiyo ejwayelekile ye Sharks. Inani amazinyo - emayelana ezingamakhulu amathathu, futhi konke lokhu ibukhali kakhulu. Jaws eside, uyakwazi esisuka ukugwinya inyamazane, hhayi raskusyvaya. Ukuzingela, umzimba ushaka egoba ngqo futhi uziphonsa phezu inyamazane kuhle kwenyoka.

ushaka komlando neze iye wafunda ngenxa ekujuleni kolwandle olwenzeka endaweni endaweni yayo. It is kuphela ezimweni ezimbalwa lapho izinto ezinjalo ziye ukubanjwa niphila ezaziwayo. Isikhathi sokugcina kwenzeka ngo-January 2007. Budebuduze isikebhe ka umdobi Japanese kwavela okuthile ababekufunde ngaphambili ezingabonwayo. Umdobi ukutshelwa yilokho ezakubona nokuphathwa epaki "Avasima" (esiqhingini Honshu, Shizuoka). I-Japanese kungukuthi kuphela ngabanjwa, kodwa futhi izithombe lokhu umhlaseli. Izinhlanzi kwaba 1.6 m ubude, coiled njengoba induna. Lwabalwa namazinyo 300, imigqa 25. ushaka Frilled wafakwa chibi ngamanzi olwandle, kodwa washona ngemuva kwamahora ambalwa. Cishe, isifo wayiphoqa ukuba avuke emajukujukwini olwandle. Lokhu bayaqagela.

ushaka Frilled sinenai commercial akuyona njengoba kakhulu ezingavamile. Futhi njalo umhlangano indoda yakhe - umcimbi (ngoba abantu, vele). Eziningi zalezi "ukuvakashelwa" kukhona okungahleliwe. Abantu wamisa kwenethiwekhi benthic nezimfanzi beshesha. Futhi edonsa inethiwekhi, bheka nje lezi zidwedwe, ngakho abadobi Japanese ababheke izinambuzane.

Muva nje, emihlanganweni eminingana nabantu plaschenostsev anda. Kodwa ososayensi oyikholelwayo ukuthi lokhu kungenxa ekwandeni kwezinga lokushisa lamanzi olwandle, hhayi ngenxa yokwanda kwenani ezidla. Ezansi olwandle sintula emoyeni futhi kwalondolozwa nezakudala izidalwa eziphilayo bayaphoqeleka ukubheka ngoba engokwemvelo entsha. Ngakho, ngo-2012 abadobi Murmansk wadonsa catch "mlando". Ngo amanzi oLwandle uBarents labanjwa omele endala oshaka.

Hhayi inyamalala futhi ngeke nezinguquko eziphawulekayo, ushaka frilled bangase bathole amandla phezu ekujuleni kolwandle, ekubeni abakhileyo wawo ofanele.
