Siya emlandweni wokukhumbula ushaka owaphila eminyakeni eyizigidi eziyi-19 edlule. Igama lakhe ushaka i-megalodon. Leli gama livela olimini lwesiGreki futhi lisho ukuthi "izinyo elikhulu". Yaphila ngezikhathi zeCenozoic nePliocene futhi yayingesinye sezidalwa ezihlaba umxhwele kakhulu emhlabeni wethu wonke. Njengamanje asisekho, ngakho-ke azisekho izibonelo.
Sizokutshela zonke izici, ilukuluku lezimfihlo ze-megalodon shark.
Izici eziyinhloko
Luhlobo lukashaka, ngokwezibalo zentela, olusemndenini wakwaLamnidae. Kule ndaba kunempikiswano enkulu emhlabeni wesayensi kusukela, sikhuluma ngo a izinhlobo ezingabonwa ngamehlo abantu. Ngakho-ke, kukhona ososayensi ababeka lolu hlobo emndenini wakwa-Otodontidae.
Zonke izici zalesi silwane kufanele zibonwe kusukela kufomu yaso ezimbiwa phansi. Ngoshaka obusekela umzimba wayo ikakhulu kuqwanga. Akwaziwa kahle ukuthi ungakanani usayizi wangempela. Ukulinganiselwa okuthile kuphela okwaziwayo lokho baveza ukuthi bangakala phakathi kwamamitha ayi-14 kuye kwangama-20 ubude. Ukuze ulinganisele lobude, ubude bamazinyo ayo buthathwa njengesethenjwa uma kuqhathaniswa nalokho okungachazwa njengenguqulo yamanje ye-megalodon. Sikhuluma ngakho Ushaka omhlophe.
Mayelana nesisindo sayo, ososayensi bakwazile ukufinyelela esiphethweni sokuthi kungenzeka ukuthi ushaka obizwa ngokuthi yi-megalodon shark wawunesisindo esingaba amathani angama-50. Lokhu kusenze sacabanga kabusha ubukhulu lo shaki abengaba nabo. Isilwane esinamathani acishe abe ngama-50 singaba yingozi kakhulu kubantu futhi ikakhulu uma kubhekwa ukuthi siyisilwane esidla inyama.
Descripción
Izilwandle zasendulo zeplanethi yethu zazine-megalodon njengesilwane esidlayo. Kunjengokungathi siqhathanisa ushaka omhlophe wanamuhla kodwa ngosayizi oyihaba kakhulu. Kunjengokungathi kungaba ngesesigaba esibizwa ngokuthi "ama-super predators" lapho sifaka khona ezinye izinhlobo ezinjengeMosasaurus nePliosaurus. Lezi zilwane zazingenazo izidalwa ezihlasela imvelo futhi zaziphezulu kulo lonke uchungechunge lokudla.
Mayelana nekhanda lakhe, kungashiwo ukuthi amehlo akhe amnyama ayengena impela futhi bekungagqanyiswanga kangako kulo lonke ikhanda lakhe, ngoba umlomo wakhe wawumangalisa kakhulu. Lo mlomo wawunobude bamamitha ama-2 futhi wawuqukethe okungenani amazinyo angama-280 osayizi omkhulu kakhulu. Amazinyo ayemise okonxantathu, eqinile futhi emise okwesaha. Isisu ngasinye sidlula amasentimitha ayi-13 ubude. Amandla akhe amakhulu yiwona ayegqame kakhulu ngalo shaka. Futhi ukulunywa kwayo kwakuqine kangangokuba kwakungachoboza amathani ayi-18, amandla angaphezu kokwanele ukucekela phansi amathambo kwanoma yisiphi isisulu.
Ngokuqondene namaphiko ayo, yayinesiphetho somhlane esasingabonakala kude ne-morphology efana neseyili yomkhumbi. Zonke izitho zayo zazinde impela, kepha lokho akuzange kukwenze ushaka omncane. Amaphiko wepectoral yiwona ahlinzeka ngejubane elikhulu kwazise ayengashayelwa kanye nomsila. Kungenzeka ukuthi zazingamaphiko aminyene futhi zikhudlwana kunalezo zikashaka omkhulu omhlophe.
Umsila wayo wawufana ncamashi noshaka omhlophe. Imunce umoya-mpilo ngemiphunga esezinhlangothini zomzimba wayo. Ukugwema ukuminza, wagcina umzimba wakhe wonke uhamba njalo. Phansi kweGill bekungekho uhlelo lokumunca njengamaphaphu ethu. Ngakho-ke, kwakudingeka aqhubeke nokunyakaza okungaguquki.
Ibanga nendawo yokudla yemegalodon shark
Akuyona yonke into eyaziwa ngokuqinisekile ngalo shaka, kepha kube nezifundo ezahlukahlukene ngayo. Lezi zifundo ziveze ukuthi lesi sidlakela sasikhona kuzo zonke izilwandle zomhlaba wethu ngesikhathi seNeogene. Kuye kwenzeka futhi ukuthola ezinye izinsalela zalesi silwane ezindaweni ezingafani nezinye njengeCanary Islands, izwekazi lase-Asia, i-Australia neMelika. Lokhu kusiholela esiphethweni sokuthi ihlala isatshalaliswa kuzo zonke izilwandle zomhlaba.
Mayelana nokudla, kungenye yezinto ezidla inyama ezinkulu kunazo zonke emlandweni. Yayikwazi ukushwabadela cishe noma yiluphi uhlobo lwesilwane, kusuka kuzimfudu kuya kwezinye izinhlobo zoshaka ngisho nemikhomo. Ngamazinyo aso namandla aso amakhulu okuluma ingabhubhisa amathambo nganoma iluphi uhlobo lokudla. Kufanele kukhunjulwe futhi ukuthi ubukhulu obukhulu namandla okwenza ukuthi babe nokwesaba okukhulu kwezinye izilwane ezincane.
Ngamazinyo ayo acishe abe ngu-280 yayikwazi ukuchoboza noma yini enesisindo esifinyelela kumathani angama-20. Kwakungenakwenzeka ukuthi noma iyiphi inyamazane yayo ibaleke emazinyweni ayo. Esinye sezici ezigqamayo uma kukhulunywa ngokondla kwakuwubuhlakani bayo obukhulu uma kukhulunywa ngokuhamba emanzini nakuzo zonke izinhlobo zemvelo morphology. Ngobukhulu bamaphiko ayo nobukhazikhazi bayo lapho ifuduka, kwakungekho neze inyamazane engayibalekela.
Mayelana nesikhathi sakho sokuphila, Kulinganiselwa ukuthi i-megalodon shark yayineminyaka yobudala obuphakathi kweminyaka engama-50 no-100.
Isu lokuzingela
Njengoba sikhuluma ngomzingeli omkhulu, lo shaka osesigabeni sakhe sabadala noma angadla zonke izinhlobo zezilwane ezinkulu. Wayenesifiso esinamandla esamphoqa ukuba achithe isikhathi esiningi sempilo yakhe efuna ukudla. Kulinganiselwa ukuthi wayengadla aze afike ku-2500 XNUMX amakhilogremu ezinhlanzi ngosuku.
Ukwenza le ncwadi eshubile wayenamasu ahlukahlukene. Esinye kwakuyisifihla sakhe. Umbala wesikhumba sakhe wamenza wamangala kakhulu. Isikhumba sakhe besimhlophe noma ngezansi kanti empunga simnyama ngaphezulu. Ubani owabona kusuka phansi kuya phezulu wayengakwazi ukusho ukuthi amanzi acwebile abaleka kushaka. Ngokuphambene nalokho, labo abayibona kusuka phezulu kuya ngezansi babengaboni ukuthi yayikhona ngenxa yobumnyama bokujula. Lesi yisifihla uMegalodon ayenaso futhi esasebenza ukubamba inyamazane yabo.
Isu lakhe lalincike ekuhlaseleni ilitshe kusuka ezansi kuthatha umfutho omkhulu ngenxa yesivinini umsila waso esimnikeze sona. Ngokushesha yavula umlomo wayo yalimaza izingxenye ezibalulekile ukuze inyamazane ingakwazi ukunyakaza. Kuklebhule lezi zingxenye ezibalulekile ngokulunywa okukhulu, kushiye isilonda esikhulu esivulekile ebesingakwazi ukuphola. Walinda ukuthi isilwane siphume igazi size sife bese eqhubeka nokudla.
Ngiyethemba lolu lwazi lukusiza ukwazi okuningi nge-megalodon.
