I-blue whale iyisilwane esikhulu kunazo zonke emhlabeni. Njengayo yonke imikhomo, ingeyezilwane ezincelisayo. Umzimba wayo ungakhula ube amamitha angu-33 ubude nesisindo samathani angama-200. Inhliziyo ye-blue whale iyodwa inesisindo esilingana nesemoto encane, okungukuthi amakhilogremu angu-600 kuya kwangu-1000. Ishaya izikhathi ezingaphezu kweziyisithupha ngomzuzu, njalo impompa amalitha ayizinkulungwane ezimbalwa egazi emzimbeni.
Umkhomo oluhlaza uma uqhathaniswa nomuntu kanye nehlengethwa.
Njengeminye imikhomo, umkhomo oluhlaza kufanele uphinde uvele ngemva kwemizuzu embalwa ungaphansi kwamanzi ukuze uphefumule. Ukhipha isiphethu esikhulu esibizwa ngokuthi igalelo. Iphakama ifike kumamitha ayisishiyagalolunye ukuphakama.
Kukhona imikhomo eluhlaza okwesibhakabhaka kuzo zonke izilwandle. Bachitha ubusika ezindaweni eziningi eziseningizimu ngoba kushisa khona. Bavame ukuchitha ihlobo enyakatho. Lapho, i-blue whale ithola izinkalankala eziningi ezincane namapulangwe. Elinye igama layo lithi krill. Udla cishe amathani amathathu kuya kwamane alokhu ngosuku futhi akhe amafutha amakhulu kuwo. Uwadinga lawa mafutha asebusika. Ngoba-ke i-blue whale ayidli lutho.
Umkhomo oluhlaza awukugayi ngamazinyo ukudla kwawo, ngoba awunawo. Kunalokho, kunezingqimba eziningi zezimpondo ezinhle nemicu emlonyeni wayo, okuthiwa i- baleen. Zisebenza njengesisefo futhi ziqinisekisa ukuthi yonke into edliwayo ihlala emlonyeni womkhomo.
Lapho ama-blue whale efuna ukudla, abhukuda kancane. Usuke usushesha okomuntu ohambayo. Lapho zifuduka amabanga amade, zibhukuda cishe amakhilomitha angama-30 ngehora. Imikhomo yamaduna eluhlaza okwesibhakabhaka ngokuvamile ihamba yodwa. Ezinsikazi zivame ukwakha amaqembu nezinye ezinsikazi kanye nezingane zazo.
Imikhomo eluhlaza ivuthwa ngokobulili lapho ineminyaka emihlanu kuya kweyisithupha ubudala. Umama we-blue whale uthwala ingane yakhe esibelethweni sakhe cishe izinyanga eziyishumi nanye. Lapho izalwa, ingaba amamitha ayisikhombisa ubude futhi inesisindo esingamathani amabili nengxenye. Lokho kucishe kufane nemoto esinda kakhulu. Umama uncelisa ingane yakhe cishe izinyanga eziyisikhombisa. Bese ikala cishe amamitha ayi-13 ubude.
