Iimpawu ezibonakalayo zemikhomo eluhlaza okwesibhakabhaka
Umnenga oluhlaza, njengezinye iintlobo kwintsapho yawo, unomzimba we-fusiform, intloko ecaba kunye nebanzi, i-dorsal fin encinci ebekwe kufuphi nomsila kunye namaphiko amabini amade e-pectoral. Kodwa eyona nto iyenza ibe yodwa ngokwenene yile ubukhulu obungaqhelekanga. Mkhulu kangangokuba umntu omdala unokudada kwimithambo yawo emikhulu. Ulwimi lwayo lunzima okwendlovu kwaye intliziyo yayo ilingana nemoto encinci.
Nangona ubukhulu bayo bukhulu, umnenga oluhlaza nawo uyakhawuleza kakhulu. Inokufikelela kwisantya esingama-50 km/h xa ifuna ukubaleka engozini. Ngokuqhelekileyo, nangona kunjalo, ibonisa isantya esizolileyo, ihamba ngesantya esiphakathi kwe-5 kunye ne-20 km / h.
Ukuziphatha komnenga oluhlaza
Iminenga eluhlaza zizilwanyana ezihlala zodwa. Ngokuqhelekileyo bayahamba baze bafune ukutya bodwa okanye ngamaqela amancinane. Noko ke, ebudeni bexesha lokuzala, ziqokelelana nezinye iintlobo zazo kumanzi ashushu, ashushu.
Nangona ubukhulu bayo bukhulu, iminenga eluhlaza yaziwa ngokuzola noxolo. Azinabungozi ebantwini kwaye azibonakalisi ndlongondlongo kwezinye izilwanyana zaselwandle, ngaphandle kwaxa ziziva zisongelwa okanye zisengozini.
Ukutyisa iminenga eluhlaza okwesibhakabhaka
Ukutya okuphambili komnenga yikrill, ikhrill encinci efana nekhrastasia. Kuqikelelwa ukuba umnenga oluhlaza utya malunga neetoni ezi-4 zekrill ngosuku. Baye babonwa besondla kumphezulu wolwandle ebusuku, xa izikolo zekrill zixinene kakhulu.
Indawo yokuhlala eblue whale
Indawo ezihlala kuyo ezi zigebenga zaselwandle yahlukene. Iminenga eBlue ihlala kwiilwandlekazi zehlabathi. Zinokufumaneka zombini kumanzi aseArctic nase-Antarctic nakumanzi ashushu. Kodwa ukuhanjiswa kwayo kunxulumene kakhulu neendlela zayo zokufuduka kunye neendawo ezityebileyo kukutya.
Iimfuno zeminenga eluhlaza
- Iminenga eBlue yenza esona sandi siphakamileyo saso nasiphi na isilwanyana eMhlabeni. Ezi zandi, ezithatha uhlobo lweengoma, zinokuqondwa ngeminye iminenga kumgama ongange-1.600 km.
- Ukukhulelwa kwiminenga eluhlaza kuthatha malunga neenyanga ezili-11. Xa usana luzelwe, lumalunga neemitha ezisi-7 ubude kwaye ubunzima bumalunga neetoni ezi-3.
- Ubomi obulindelekileyo beminenga eluhlaza bumalunga nama-70 ukuya kuma-90 eminyaka, nangona kukho iimeko zabantu abafikelela kwiminyaka eyi-100 ubudala.
Uphononongo kunye nolondolozo lwe-blue whale kubaluleke kakhulu namhlanje. Nangona ukuzingelwa kwezi zilwanyana kwavalwa ngo-1966, ezi zilwanyana zihlala zisemngciphekweni kwaye zibonwa njengengozi yokuphela. Ukusinda kwazo kuxhomekeke ekusebenzeni nzima kwabalondolozi bendalo nasekufundeni rhoqo ngezi zidalwa zinomtsalane, ezi iingxilimbela ezingenakuphikiswa zolwandle.
