I-prehistoric Megalodon (I-Otodus megalodon) kwakungushaka okucatshangwa ukuthi washabalala eminyakeni eyizigidi ezingu-3.6 edlule. Lesi silwane sasisikhulu, okwenza kwaba ushaka omkhulu kunabo bonke abake baba olwandle futhi umhlaseli omkhulu kunawo wonke owake wabonwa emhlabeni. Yayisabalele, itholakala kuzo zonke izilwandle ezishisayo nezipholile.
I-Megalodon - umdondoshiya wangaphambi komlando
I-Megalodon ihumusha ngokuthi 'izinyo elikhulu', okuyigama elifanelekile: okukodwa nje kokugedla kwayo kungagcwalisa intende yesandla sakho. Ngokuphambene, izinyo likashaka omkhulu omhlophe lilingana nomunwe wakho omncane.
Ososayensi balinganisela ukuthi i-megalodon ingakhula ibe ngamamitha angu-18 ubude. Ngokomongo, lobo ubude boshaka abamhlophe abacishe babe abathathu.
Idle ini i-megalodon?
Ukuliphila libe likhulu kangaka kudinga inani elikhulu lokudla. I-Megalodon ngokwawo wonke ama-akhawunti yayiyisilwane esihlaselayo esinonya - isilwane esikhulu esinonya empeleni - esikwazi ukubamba izisulu eziningi ezifana nemikhomo, izimvu zamanzi, izimfudu nabanye oshaka. Cishe yasondela inkwali yayo ngemuva, yayibamba ngaleyomihlathi enamandla enamazinyo angaphezu kuka-270, ihlelwe ngemigqa, futhi iyigawula ngemilomo embalwa.
Njengabo bonke oshaka, amazinyo e-megalodon ayechitheka njalo futhi akhule kabusha. I-bite-force yayo yayimangalisa, kusukela ku-100,000 - 180,000 Newtons. I-T-Rex ingaluma ngamandla ama-Newtons angu-64,000. I-Megalodon nayo yaba ne-gas enkulu ehlanganisa amamitha amabili, eyayenza yakwazi ukugwinya imikhomo ebulalayo iphelele.
I-megalodon yaphela nini futhi kungani?
Ososayensi abazi kahle ukuthi i-megalodon yafa nini, kodwa bazi ngobufakazi bezinsalela zokuthi kwaba nesikhathi esithile ePliocene (eminyakeni eyizigidi ezingu-5.3-2.6 edlule), lapho amazinga okushisa eqala ukwehla futhi iplanethi iphola.
Isenzakalo esibalulekile sokupholisa kanye nokwehla okuhlobene namazinga olwandle iplanethi eyabhekana nakho ngesikhathi se-Pliocene kube nemiphumela emikhulu nefinyelela kude kuzo zonke izilwane zasolwandle - izinhlobonhlobo zezinto eziphilayo zalahleka phakathi nalesi sikhathi.
Ukukhiqizwa kolwandle kwancipha futhi izinhlobo eziningi zasolwandle zafa, kuhlanganise nenani elikhulu lezilwane ezincelisayo zasolwandle ebezingaba yingxenye yokudla kwe-megalodon. Ngenxa yokungabi bikho kwenyamazane, lo mzingeli omkhulu, ohlezi phezulu ochungechungeni lokudla, wayezoqala ukulamba aze ashabalala. Idethi esondele kakhulu elinganiselwe yokubhukuda kokugcina kwe-megalodon yiminyaka eyizigidi ezingu-3.6 edlule.
Ingabe i-megalodon yashintsha yaba oshaka abamhlophe abakhulu banamuhla?
Sekuyisikhathi eside ososayensi bekholelwa ukuthi i-megalodon shark yangaphambi komlando yashintsha yaba isilwane esizingelayo sanamuhla esesabeka kunazo zonke, esimhlophe esikhulu. Nokho, ucwaningo olusha oluqhathanisa amazinyo lubonisa ukuthi ushaka omkhulu omhlophe uhlobene kakhulu noshaka i-mako shark ononya ngokulinganayo.
