Iminenga kulula ukuyibona ngenxa yobukhulu bayo, kodwa zininzi iinkalo zezi zidalwa ezingaziwayo kangako. Ukuze siqonde ukuba yintoni umnenga, ngaphaya kobukhulu bawo, kufuneka sihlolisise ibhayoloji yawo, indlela oziphatha ngayo, indlela otya ngayo, indawo ohlala kuyo, kwanezinye izibakala ezibangel’ umdla ngawo.
I-Anatomy kunye nePhysiology yeWhales
Iminenga inemizimba emikhulu, emide elungele ukuziqhelanisa nobomi elwandle. Zihlelwa zibe ngamaqela amabini: iminenga yebaleen kunye neminenga enamazinyo. Abokuqala basebenzisa ezi iindevu ukuhluza izilwanyana ezincinci emanzini, ngelixa ezokugqibela zisebenzisa amazinyo ukubamba amaxhoba.
Ubungakanani beminenga buyahluka kakhulu. Umnenga oluhlaza, esona silwanyana sikhulu kwezakha zakho, unokufikelela kwiimitha ezingama-30 ubude kwaye nobunzima obuziitoni ezingama-200. Kwelinye icala, umnenga iBeluga awukho mkhulu kunehlengesi.
Ukuziphatha komnenga
Ukuziphatha komnenga kunzima kakhulu kwaye kutyebile ngokweenkcukacha. I iminenga enamazinyo Ngokuqhelekileyo basekuhlaleni kwaye baziwa ngokuziphatha kwabo okudlalayo. Iintlobo ezininzi zezilwanyana zaziwa ngokutsiba kwazo okuchukumisayo kuphuma emanzini, okubizwa ngokuba yi-gaps.
Kwelinye icala, iminenga yebaleen Bathanda ukuba bodwa okanye bahambe ngamaqela amancinci. Nangona kunjalo, le minenga nayo ineendlela zokuziphatha ezinomdla, ezifana nokwenza "iminatha ye-bubble" ukubamba i-krill.
Ukutya kweWhale
Iminenga ineentlobo ngeentlobo zokutya ezixhomekeke kwiintlobo zazo, ubukhulu kunye nendawo yokuhlala. Abanye, njengeminenga eluhlaza kunye ne-fin, batya izinto ezincinci ezifana nekrill kunye ne-shrimp. Basebenzisa iindevu zabo ukucoca ezi ntsholongwane zincinci emanzini.
Kwelinye icala, iminenga enamazinyo, njenge-orcas, itya iintlanzi nezinye izilwanyana zaselwandle. Ngokomzekelo, i-Orcas, idume ngokukwazi ukuzingela iintini kwakunye neminye iminenga.
Indawo yokuhlala yeWhale
Iminenga ifumaneka kuzo zonke iilwandlekazi zehlabathi, ukusuka kumanzi ashushu ashushu ukuya kwiilwandle ezibandayo zepolar. Ezinye iintlobo, ezifana ne-grey whale kunye ne-humpback whale, zihamba ngokumangalisayo amawaka eekhilomitha nyaka ngamnye ukuze zondle kwaye zivelise kwakhona.
Eminye, enjengomnenga we-beluga okanye i-right whale, inoluhlu olubekelwe imiqathango ngakumbi kwaye ubukhulu becala ifumaneka kwimimandla ethile yeArctic okanye kuMntla weAtlantiki ngokulandelelanayo.
Iimfuno malunga neMinenga
- Iminenga zezona zilwanyana ziphila ixesha elide kwiplanethi. Kukholelwa ukuba eminye iminenga yaseArctic inokuphila iminyaka engama-200.
- Iminenga inolwimi lwayo. Ingoma yeminenga sesinye sezona zandi zintsonkothileyo ezenziwa sisilwanyana.
- Iminenga inegalelo kwimpilo yendalo yaselwandle. Xa umnenga usifa waza umzimba wawo uzika elwandle, ubonelela ngokutya kwezilwanyana ezininzi ezisemhlabeni wolwandle.
Ekugqibeleni, iminenga zizidalwa ezinomdla kwaye ezibalulekileyo kwiilwandle zethu. Njengawona makhonkco aphezulu kwikhonkco lokutya kwaselwandle, adlala indima ebalulekileyo kwimpilo yendalo yaselwandle. Ukukhuselwa kunye nokugcinwa kwazo kubalulekile kwimpilo yeelwandle zethu.
