Ushaka yinqanawa. Ngaba isilwanyana esiyimfihlakalo siyaphila - megalodone?

Uninzi lwazinzulu-ichthyologists zikholelwa ukuba iintlanzi ezimhlophe ezimbi ezibizwa ngokuthi "megalodon," sele ziphele. Nangona kunjalo, kukho iimbono kunye neengxelo ezithetha ukuba i-shark-submarine (njengokuba le ngqungquthela yeentlanzi ezimhlophe zibiza ngokuba) ihlala ihlala elunxwemeni lolwandle olunzulu olungafinyeleleki kubantu. Makhe sizame ukuqonda le ngxaki, ngokusekelwe kwiirekhodi zezenzululwazi, zabo iziphumo kunye neengcamango.

Ibali likaDavid George Stead

UDavid George Stead wayengomnye wabasosayensi abadumileyo nabahloniphekileyo kwintsimi ye-ichthyology. Kwakuye ibali lakhe, elipapashwe emva kokufa kwakhe, okwaba yintlungu kwaye yavumela ukungathandabuzeki ukuba i -submarine emhlophe ye-shark ayikho.

Ngomnyaka we-1918, inzululwazi oselula yayisebenza e-Australia kwaye yayijongene nokuloba kwi-Southern Shores. Ngelo xesha iileta ivela kwi-port enkulu ukuya kwi-arhente karhulumente ejongene nokuloba, okufuna ikhonkco epheleleyo yenkinga eyodwa. Abalobi babecala ukuba kufuphi nxweme lwaseAustralia, kukho isidalwa esibi, intlanzi engaziwayo, esongela ukuba bonke bayesaba ukuya elwandle.

Intlanganiso enzima

Ibali elithwele intliziyo elindile elunxwemeni ... Abalobi belo mkhumbi baya elwandle baza baya kwindawo ababehlala kuyo kwiindawo ezinzulu ze-lobster. Iintlobo, zehla ezinzulwini, ukuze zikhuphe izixhobo zeemigibe, zikhuphuke phezulu ngejubane elinqabileyo. Ngokukhawuleza ukukhawuleza kwidonki, baxelele ukuba ekujuleni kwe-shark enkulu. Iindidi zitsho ukuba udoki unamathele ngokukhawuleza ngokubamba emva kwesinye. Kodwa bazinzile ngeensimbi zensimbi! Kwaye akuzange kumkhathaze. Ngokukhawuleza ihake ibonakale phambi kwamehlo kunye nalo lonke iqela lokuloba. Ukulibala i-catch, baqalisa ngokukhawuleza iinjinjini baza bashiya indawo eyoyikayo.

Kakade, njengososayensi, uDavid George Stead waqaphela ukuba udoki onexesha lomzimba elingaphezu kweemitha ezingamashumi amathathu alinakho. Kodwa kwakungekho nto yokuthetha amanga kubalobi abesabisayo. Hamba ukhangele, ufumane ubungqina obunobani. Abalobi babemvume ngokungafuni ukuya elwandle.

Umjelo "uRachel Cohen"

Emva kweeminyaka emininzi, i-shark-submarine (njengabalobi ababizwa ngokuba yi-fishery for name size) bawakhumbuza ngokwabo kwakhona. Ngo-1954, kwakhona kwinqanawa yaseOstreliya, umkhombe "uRachel Cohen" wema kwindawo yokulungisa kunye "nokucoca ngokubanzi". Xa iinqanawa zahlanjululwa iinqabileyo ezininzi, zafumanisa amazinyo asixhenxe anesixhenxe. Izinyo ngalinye, ngokuzibonela ngamehlo, kwakungaphezu kweesentimitha ezilisibhozo ngobukhulu. Iingcali zenzululwazi zisekwa ukuba zazingenabani na ngaphandle kwe-shark megalodon. Ukubhekisela: ubude bezinyo zeshaki eziqhelekileyo ziphela ezintathu ukuya kweesentimitha ezintathu.

Izinto ezinobungozi zendalo azikaze zenziwe

Ngokwenzululwazi, i -submarine emhlophe e-white-shark iyona nto inesabekayo, yegazi neyoyikayo yoMama. Ngokweziqikelelo, ubude balo buphakathi kweemitha ezimashumi mabini ukuya kumashumi amathathu anesihlanu, kwaye amanani omzimba anama-50 ukuya kwekhulu. Iimbongolo ze-Sperm, ezibhekwa njengenye yezona ndawo zininzi zihlala ezinzulwini zolwandle, ziyintlanzi nje ye-megalodone. Kunzima ukucinga ukuba bunjani umlomo unomkhumbi we-shark, ukuba i-whale ingamitha ezili-10 ubude - ukuveliswa kwimihla ngemihla lula isidlo sakusihlwa.

Iingcali zenzululwazi ziye zafumana amazinyo amakhulu emhlabeni wonke kangangeminyaka emininzi. Enye enye inkcazo yokuba i-submarine emhlophe ye-shark ikhona kwaye inokwakheka kobukhulu bokuhlala.

Kwankqantosa ukucinga i-monster enobungakanani obukhulu, xa kuthelekiswa nendoda yinto encinci yentlabathi. I-submarine yerkki, isithunzi apho izazinzulu zabuyisela ngokubonga kwiziphumo kunye neengcamango, yinto edalwa kakubi. I-squelette-wide skeleton, imihlathi emininzi, apho imigca emihlanu yezinyo kunye nesisiphukuphuku "i-snout" ifihla. Baye bahlekise ukuba i-megalodon injengengulube. Ngokusemthethweni uqala ukuvuya ukuba ezi zidalwa zifile.

Kwaye nokuba bafa?

Izazinzulu-izazi ze-geologists ziyabona ukuba izilwanyana ziphela kuphela xa zingekho "iindaba" zazo iminyaka eyi-400 lamawaka. Nangona kunjalo, amabali abalobi abavela kwi-port yase-Australia, amazinyo atholakala kwinqanawa ethi "Rachel Cohen" amazinyo - konke oku kubonisa ukuba i-submarine ye-shark ikhona. Amazinyo ayexhomekeke kwizifundo ezininzi, kwaye umphumo wukuthi bangabanye be-megalodone.

Kwaye "amazinyo" enqabileyo enkulu ayengacatshangwanga kakuhle. Ziyiminyaka elineshumi ukuya kwishumi elinesibhozo ubudala. Qondani umehluko: amawaka angama-400 amawaka ne-11 lamawaka! Kuye kwenzeka ukuba kwindawo ethile ekudeni kolwandle kusekho kwaye i-submarine emhlophe e-shark iziva kakuhle. Ubu bungqina bokuba kubakho rhoqo. Kwaye oku malunga nento ewe ithi.

Ngendlela, umzekelo, i-goblin shark, eyayiyiminyaka emininzi ithathwa njengeyaphela, yafunyanwa ngo-1897 kwi-World Ocean. I- whale shark, ebukho bokuba yayingekho ixesha elide lingakholelwa, labhalwa ngo-1828. Mhlawumbi i-sous-marine yehokki ilinde ixesha layo kwindawo ethile.

Ayengabonwa njani?

Kubonakala ngathi ubungakanani obukhulu besilwanyana abukwazi ukungaqapheli iminyaka emininzi. Izidalwa ezikhulu ngokuqinisekileyo zaziye zibonwa ukusuka elunxwemeni, ukuya emanzini okanye kwi-stern of the ship. Kodwa ukuba ucinga ngako, ubukhulu obukhulu bala ma giantsane nje abavumeli ukuba bahambile ngaselunxwemeni. Yincinci kakhulu kubo.

Ukongezelela, i-submarine ye-shark ingabikho ngokukhuselekileyo elwandle. Ngokomzekelo, izilwanyana ezinkulu - izilwanyana zamabhawu - zihlala zithe cwaka kwiikhilomitha ezintathu. Umntu akanako ukufikelela ezinzulu, nangona kukho ukuphuhliswa kwee-submarines zamanje. Ubunzulu obunjalo abukatholakali kuthi. Yaye ukuba uthelekisa ubungakanani benkonzo yamaduna kunye neentlanzi-i-submarines, ngoko oku kuzuza ngokucacileyo. Ngenxa yoko, ubunzulu bokubhaptizwa kwabo bunokuba lukhulu kunokuba "bengathobeli" iikhilomitha ezintathu.
