Ei-oarfish ingenye yezinhlobo ezivame kakhulu akhona kuzo zonke izindawo ezipholile nezishisayo zomhlaba. Igama layo lesayensi ngu U-Regalecus glesne futhi ungowomndeni we-regalecidae. Zisungulwa emanzini olwandle cishe kuwo wonke umhlaba. Kubhekwa njengenye yezinhlanzi ezinde kunazo zonke emhlabeni, ifinyelela kumamitha ayi-17 ubude.
Inhlanzi yalobu bude ibukeka njengesilo kunenhlanzi ejwayelekile, ngakho-ke kufanelekile ukwazi. Ngabe ufuna ukufunda konke mayelana nale nhlanzi?
Izici ze-oarfish
Yize kuyinhlanzi engamamitha ayi-17 ubude, Akuyona inhlanzi enkulu kunazo zonke emhlabeni. Inomphetho omkhulu wangemuva oyinikeza ukuma okungajwayelekile nofana nenyoka.
Akusona isilwane esiyingozi, ngoba sinesimo esizolile ngokwanele. Ngoba cishe ihlala ihlala ekujuleni, akukho okuningi okwaziwayo ngale nhlanzi. Bayakwazi ukuhambela phezulu lapho besondele ekufeni noma begula kakhulu.
Umzimba wayo mncane impela futhi uyisicaba, yingakho yaziwa nangokuthi yinhlanzi eyi-saber. Ayinazo izikali, kepha kunalokho inemvilophu eyakhiwe nge-guanine yombala wesiliva. Yize umlomo wakhe uqhamuka, akawavezi amazinyo akhe.
Isiphetho sayo sangemuva sikhulu kakhulu. Isuka phezulu kwamehlo iye ekugcineni komsila. Iba bomvu noma ibomvana futhi ithatha wonke umzimba wakho. I-dorsal fin inayo ameva angamakhulu amane, eziyishumi nambili zazo zinwetshiwe, okuyinika ukubukeka okumangazayo.
Amaphiko ezinqeni anezinto ezifanayo nezomgogodla, futhi esimweni sawo sifana nesigwedlo (yingakho igama laso elijwayelekile). Ngakolunye uhlangothi, amaphiko we-pectoral mancane kakhulu, kunzima ukuwabona kanti amaphiko awo we-caudal kanye ne-anal mancane kakhulu.
Ukuziphatha kweRegalecus glesne
Njengoba kushiwo ngaphambili, i-oarfish iyinhlanzi ezolile kakhulu. Kungashiwo ukuthi iyinhlanzi enamahloni enamahloni okudonsela ukunakwa. Lapho izingelwa yizilwane eziyizingelayo, ibalekela ekujuleni iphephele emadwaleni. Ichitha impilo yayo yonke ekujuleni, ibhukuda futhi izivikele ezilwaneni eziyingozi.
Ukubhukuda isebenzisa i-dorsal fin yayo futhi ikwenza ngokuqonde ngqo phezulu. Zitholakala ekujuleni zibhukuda zibheka. Iyakwazi futhi ukubhukuda ngokuvundlile, ngoba inohlelo lwe-locomotion oluyimpumelelo kakhulu oluyivumela ukuthi isebenzise izindlela ezahlukahlukene zokushintsha ukuqondiswa nokuqondiswa. Ikwenza lokhu ngenxa yesiphetho sayo sangemuva.
Ngokuvamile ziyizinhlanzi ezizimele futhi azivamile ukubonakala eduze kwesinye isifanekiso sohlobo olufanayo. Kungabonakala neqembu elincane lapho bethuthela kwenye indawo yokuhlala, yize bengahlali ndawonye, kepha bahlala kude.
Isikhathi esiningi itholakala intanta eduze kwamabhange ngoba zikhukhulwa yimisinga yolwandle lapho sebevele begula noma sebekhulile futhi bengakwazi ukumelana nemisinga. Zithathwa njengezilo zasolwandle eziyiqiniso ngosayizi wazo kanye inhlanzi zamatshe.
Indawo nendawo okusatshalaliswa kuyo
Inhlanzi eyi-saber ihlala khona ekujuleni kufinyelela kumamitha ayi-1000. Ngenxa yekhono layo lokuguqula izinga lokushisa lomzimba lilinganise cishe ama-degree Celsius angamashumi amabili, itholakala cishe kuzo zonke izilwandle zomhlaba, ngaphandle kwezindawo ezipholile. Imvamisa iyinhlanzi efudukayo, ngakho-ke ayihlali isikhathi eside endaweni eyodwa. Kodwa-ke, itholakala kalula ezindaweni ezishisayo zezilwandle ezipholile.
Bahamba amabanga amade ukusuka emanzini ahlukahlukene ukuyofuna ukudla nendawo yokuhlala futhi babalekele izidlo zabo. Iyakwazi ukuzulazula kusuka ekujuleni kwamamitha angama-20 kuye kwayi-1000 ngendlela esheshayo.
Ukudla
Ukudla kwabo kudla ngokuphelele. Bangena ekudleni kwabo i-squid, izinhlanzi ezincane, ama-crustaceans ngisho nama-plankton. Yenza ukubamba kwayo ngomzamo omkhulu, ngoba kufanele isebenzise imiphunga yayo.
Njengoba ingenamazinyo, ayikwazi ukuluma isisulu sayo ukuze idle. Kepha njengoba ukuziphendukela kwemvelo kuhlakaniphe kakhulu, lolu hlobo luye lwazivumelanisa nalo. Ukuntuleka kwamazinyo kukwenzela ama-gill rakers enzelwe ukuzingela. Zibunjwe ngokufana neharika begodu zisetjenziselwa ukudonsa isilulu sazo ngokunethezeka.
Ngokubhukuda ubheke phezulu, uthola inzuzo kunezinye izinhlanzi, njenge inhlanzi endizayo. Lezi zinhlanzi zibhukuda zivundle futhi zingahlala eduze kwamanzi.
Ukuzala
Yize kuncane okwaziwayo ngale nhlanzi, kuyaziwa ukuthi isikhathi sokuzala senzeka phakathi kukaJulayi noDisemba. Ngalesi sikhathi kulapho befaka inani elikhulu lamaqanda. Usayizi walezi isukela kumamilimitha ayi-2,5 futhi ziphonswa ngaphezulu lapho zilokhu zintanta zize zichamuke.
I-oarfish ivundiswa ngaphandle, ngoba amaqanda afakwa ngaphandle komzimba wowesifazane. Owesilisa uhlala endaweni ezungezile yowesifazane ukuze amvikele kunoma iyiphi ingozi. Lapho owesifazane ekhipha amaqanda, owesilisa uyehlisa isidoda sakhe bese uyawafaka umquba.
Lapho amaqanda echanyuselwa, izibungu zihlala isimo sezulu esihle ezindaweni ezisondele phezulu zize zikhukhulwe yimisinga ziye ezansi. Lapho sezingaphansi kolwandle, zihlala lapho zize zikhule zibe abantu abadala.
Ilukuluku lwenhlanzi eyi-saber
I-oarfish inesici esiyenza ikhetheke futhi yehluke kwezinye de peces futhi akusibo ubude bayo. Imayelana amandla okuzenzela inhloso isitho. Kukholakala ukuthi ikwenza lokhu ngokuluma umsila wayo ukuze izikhulule kumzingeli wayo. Kodwa-ke, lokhu angeke akwenze ngoba uswele amazinyo.
Okwenzekayo ukuthi iyakwazi ukuzihlukanisa nengxenye yokugcina yomzimba wayo ukuze ibalekele izisulu zayo bese iyakwazi ukuziphindisela. Lokhu kungenziwa izikhathi eziningi kuyo yonke impilo yakho.
Njengoba ukwazi ukubona, i-oarfish iyinhlanzi esaphila futhi kufanele uyazi.
