Ngokuvamile, abantu bayathandwa yizilwane, kepha izilwane ezivezwa ngosayizi abakhulu zivame ukuheha thina kakhulu. Ezinye zalezi zinhlobo ze usayizi ongavamile basaphila, kuyilapho abanye baziwa kusukela kumlando wezinsalela futhi eziningana ziyingxenye yezinganekwane ezixoxwa ngokuhamba kwesikhathi.
Esinye isilwane esinjalo esichaziwe yi-megalodon shark. Imibiko ikhombisa ukuthi lesi silwane sizoba nokulingana okungajwayelekile. Kangangokuthi wayebhekwa njenge- izinhlanzi ezinkulu kakhulu ezake zaphila eMhlabeni, yini engenza lesi silwane sibe ngumzingeli omkhulu wezilwandle.
Unentshisekelo yokwazi okwengeziwe ngale nyama enkulu edla inyama? Ngakho-ke sikumema ukuthi uqhubeke nokufunda le ndatshana yePeritoAnimal ukuze ukwazi ukucacisa okungaziwa bese uphendula: ngabe kuzoba njalo ingabe i-megalodon shark ikhona?
Yayinjani i-megalodon shark?
Igama lesayensi le-megalodon shark ngu I-Carcharocles megalodon futhi yize phambilini bekuhlukaniswa ngendlela ehlukile, manje sekukhona ukuvumelana okubanzi ukuthi kungokwe-Lamniformes (lapho ushaka omkhulu omhlophe ungowakhona), umndeni ongasekho u-Otodontidae kanye nohlobo oluphelile ngokulingana iCarcharocles.
Isikhathi eside, izifundo eziningana zesayensi, ngokususelwa ekulinganisweni kwezinsalela ezitholakele, zaphakamisa ukuthi lo shaka omkhulu kungenzeka abe nobukhulu obuhlukile. Ngalo mqondo, i- megalodon shark kwakucatshangwa ukuthi cishe ingamamitha angama-30 ubude, kepha ingabe lolu usayizi wangempela we-megalodon?
Ngokuthuthuka kwezindlela zesayensi zokufunda izinsalela zezinsalela, lezi zilinganiso kamuva zalahlwa futhi manje kwatholakala ukuthi iMegalodon yayinayo cishe ubude bamamitha ayi-16, nekhanda lilinganisa cishe amamitha ama-4 noma ngaphezulu, ngobukhona bomphetho wokugcoba owedlula amamitha ayi-1.5 nomsila cishe ngamamitha amane ukuphakama. Ngaphandle kokungabaza, lobu bukhulu bunobukhulu obubonakalayo benhlanzi, ukuze ibhekwe njengobukhulu kunabo bonke eqenjini layo.
Okunye okutholakele kwasivumela ukuthi sithole ukuthi i-megalodon shark yayinemihlathi emikhulu impela eyayilingana nobukhulu bayo obukhulu. Le mandible yakhiwa ngamaqembu amane amazinyo: ngaphambili, phakathi, ngemuva nangemuva. Izinyo elilodwa lalo shaka lalinganiselwa ku-168 mm. Ngokuvamile, ziyizakhiwo ezinkulu zamazinyo ezingunxantathu, lapho kukhona khona imisele emihle emaphethelweni nendawo enobuliminhi eyi-convex, kuyilapho ingaphezulu le-labial lihluka ukusuka kokuncane kuya kusiyingi, kanti intamo yamazinyo imise okwe-V.
Amazinyo angaphambili ajwayele ukulingana futhi abe mkhulu, kuyilapho ifayili le- amazinyo asemaceleni izindlu zangemuva azilingani kancane. Futhi, njengoba umuntu eya endaweni engemuva kwe-mandible, kukhona ukwanda okuncane phakathi nendawo phakathi kwalezi zakhiwo, kepha bese kwehla kuya ezinyo lokugcina.
Esithombeni singabona izinyo le-megalodon shark (kwesobunxele) nezinyo le- Ushaka omhlophe (kwesokudla). Lezi yizona kuphela izithombe zangempela zomearkodon shark esinazo.
Funda kabanzi mayelana nezinhlobo ezahlukahlukene zoshaka ezikhona kulesi sihloko.
Ngabe i-megalodon shark yaphela nini?
Ubufakazi bukhombisa ukuthi lo shaki waphila kusukela eMiocene kuya ekugcineni kwePliocene, ngakho-ke i-megalodon shark yanyamalala cishe eminyakeni eyizigidi ezi-2,5 kuya kwezi-3 edlule.. Lezi zinhlobo zitholakala cishe kuzo zonke izilwandle futhi zihamba kalula zisuka ogwini ziye emanzini ajulile, ngokuthanda amanzi asezingeni eliphansi kunamanzi aphansi.
Kulinganiselwa ukuthi imicimbi eminingana yokwakheka komhlaba kanye nezemvelo inegalelo ekuqothulweni kukashaka we-megalodon. Omunye wale micimbi kwaba ukwakheka kwe- Isthmus yasePanama, okwaletha ukuvalwa kokuxhumana phakathi kwezilwandle iPacific kanye ne-Atlantic, kwaletha izinguquko ezibalulekile emisinga yolwandle, amazinga okushisa kanye nokusatshalaliswa kwezilwane zasolwandle, okuyizici okungenzeka ukuthi zazithinta kakhulu lolu hlobo okukhulunywa ngalo.
Ukwehla kwamazinga okushisa olwandle, ukuqala kwenkathi yeqhwa kanye ne- izinhlobo ziyancipha okwakuyizisulu ezibalulekile zokudla kwabo, ngokungangabazeki zazithatha isinqumo futhi zivimbela ushaka we-megalodon ekuqhubekeni nokukhula ezindaweni zokuhlala ezanqotshwa.
Kulesi esinye isihloko sikhuluma ngezilwane zasolwandle zangaphambi komlando.
Ingabe i-megalodon shark njengamanje ikhona?
Wena izilwandle ziyimvelo enkulu, ukuze kungabikho konke ukuthuthuka kwesayensi nobuchwepheshe okutholakalayo namuhla okusivumele ukuba siqonde ngokugcwele ngobuningi bempilo ezindaweni zasolwandle. Lokhu kuvame ukuholela ekucabangeni noma ekuqhamukeni kwemibono ngobukhona bangempela bezinhlobo ezithile, kanti i-megalodon shark ingenye yazo.
Ngokusho kwezinye izindaba, lo shaka omkhulu angahlala ezindaweni ezingaziwa ososayensi kuze kube namuhla, ngakho-ke, angatholakala ezinzulwini ezingakahlolwa. Kodwa-ke, ngokujwayelekile kwisayensi, izinhlobo I-Carcharocles megalodon icishiwe ngoba abukho ubufakazi bokuba khona kwabantu abaphilayo, okungaba yindlela yokuqinisekisa noma cha ukuqothulwa kwayo okungenzeka.
Ngokuvamile kukholelwa ukuthi uma i-megalodon shark isekhona futhi ingekho e-radar yezifundo zasolwandle, bekungaba njalo izoletha ushintsho olukhulu, njengoba kufanele ukuthi ivumelane nezimo ezintsha ezavela ngemuva kokuguqulwa kwemvelo yasolwandle.
Ubufakazi bokuthi i-megalodon shark yayikhona
Umbhalo wezinsalela zamandulo ubalulekile ekukwazi ukunquma ukuthi iziphi izinhlobo ezikhona emlandweni wokuziphendukela kwemvelo woMhlaba. Ngalo mqondo, kunerekhodi elithile lezinsalela ezihambisana noshaka we-megalodon wangempela, ikakhulukazi izakhiwo zamazinyo, izinsalela ze umhlathi kanye nezinsalela eziyingxenye ye- amathambo. Kubalulekile ukukhumbula ukuthi lolu hlobo lwezinhlanzi ikakhulukazi lwakhiwe ngezinto ezinesigaxa, ngakho-ke eminyakeni edlule, futhi njengoba ingaphansi kwamanzi anokugcwala okusawoti kakhulu, kunzima kakhulu ukuthi izinsalela zayo zigcinwe ngokuphelele.
Izinsalela ze-megalodon shark zitholakala ikakhulu eningizimu-mpumalanga ye-United States, Panama, Puerto Rico, Grenadines, Cuba, Jamaica, Canary Islands, Africa, Malta, India, Australia, New Zealand nase Japan, okukhombisa ukuthi ubukhona bomhlaba wonke.
Ukuqothulwa futhi kuyinqubo engokwemvelo ngaphakathi kwamandla asemhlabeni futhi ukunyamalala kwe-megalodon kungenye yeqiniso elinjalo, ngoba abantu babengakaguquki kuze kube yisikhathi lapho le nhlanzi enkulu yanqoba izilwandle zomhlaba. Ukube kwaqondana, ngokuqinisekile bekuzoba yi inkinga embi eyabantu, ngoba, ngobukhulu obunjalo kanye ne-voracity, ngubani owaziyo ukuthi ngabe baziphathe kanjani ngezikebhe ebezingadlula kulezi zindawo zasolwandle.
Ushaka we-megalodon wedlula ezincwadini zesayensi futhi, ngenxa yokuthakazelisa akubanga, futhi bekuyindaba yamafilimu nezindaba, yize bekunezinga eliphezulu lezindaba eziqanjiwe. Okokugcina, kucacile futhi kufakazelwe ngokwesayensi ukuthi lo shark ugcwale izindawo eziningi zasolwandle eMhlabeni, kepha i-megalodon shark ayikho namuhla kusukela, njengoba sesishilo, abukho ubufakazi besayensi balokhu. Noma kunjalo, lokhu akusho lokho ucwaningo olusha ayikwazi ukuyithola.
Manje njengoba usukwazi konke mayelana ne-megalodon shark, ungahle ube nentshisekelo kule enye indatshana lapho sichaza khona ukuthi ama-unicorn akhona noma ake aba khona yini.
Uma ufuna ukufunda izindatshana eziningi ezifana ne- Ingabe i-megalodon shark ikhona?, sincoma ukuthi ufake isigaba sethu se-Curiosities somhlaba wezilwane.
