Amaqela aphambili ezilwanyana zaselwandle
Ukuze siqonde ukuba yahlulahlulwe phi iminenga, kufuneka kuqala siqonde indlela okwakheka ngayo iintlobo ngeentlobo zeelwandle. Ubukumkani bezilwanyana bukhulu kakhulu kwaye buhlukaniswe ngamanqanaba ahlukeneyo afana nomyalelo ophezulu, udidi, ulungelelwano, intsapho, i-genus kunye neentlobo.
Umhlaba waselwandle ulikhaya kwiintlobo ngeentlobo zezinto eziphilayo, nganye kuzo ifumaneka kwelinye lala maqela mahlanu aphambili. izilwanyana zaselwandle, izilwanyana zaselwandle ezingenamqolo, iintlanzi, iintaka zolwandle kunye nezilwanyana zaselwandle.
Izilwanyana ezincancisayo zaselwandle: Phakathi kwazo kukho iminenga
Iminenga yinxalenye yeqela izilwanyana zolwandle, eyingqokelela yeendidi ezimalunga ne-130 zezilwanyana ezanyisayo ezicetywa ukuhlala elwandle. Eli qela likwabandakanya amahlengesi, iiporpoise, iimanatee, izitywina kunye neewalrus.
Izilwanyana ezanyisayo zaselwandle zineempawu ezininzi ezahlukileyo. Umzekelo, Izilwanyana ezincancisayo zaselwandle ziyabazi ubushushu bazo, zineenwele (nangona zihlala zincinci), zizala ziphila zincinci kwaye zondle ngobisi lukamama..
Ukuhlelwa kweminenga
Iminenga ihlelwa ngokolandelelwano lwezilwanyana ezincancisayo zaselwandle ezibizwa ngokuba ziicetaceans, eziquka amahlengesi neeporpoise. Ngaphakathi kolu cwangco, iminenga iyinxalenye yamacandelo amabini ahlukeneyo:
- I-Mysticeti (baleen whales): Le minenga yeyona mikhulu kwaye izondla ngenkqubo ebizwa ngokuba yi-filtration, apho ihluza umthamo omkhulu wamanzi olwandle ukuze ibambe izilwanyana ezincinci, ngakumbi iplankton kunye nekrill.
- Odontoceti (Toothed Cetaceans): Eli qela liquka iminenga ebulalayo, amahlengesi, kunye neminenga yamadlozi. Ubukhulu becala ingabazingeli beentlanzi kunye nezilwanyana zaselwandle ezingenamqolo.
Iindawo zokuhlala zeminenga
Iminenga isasazwe ngokubanzi kwiilwandlekazi zehlabathi, ukusuka kwiipali ukuya kwi-ikhweyitha. Nangona kunjalo, ukusabalalisa kwabo akukwabiwa ngokufanayo kwaye kuxhomekeke kakhulu ekudleni kwabo, isimo sokuzala kunye nexesha lonyaka.. Ngelixa uninzi lweentlobo zeminenga lufumaneka kumanzi abandayo kwincam yencam, eminye ihlala kumanzi ashushu okanye apholileyo.
Amasiko kunye nendlela yokuphila yeminenga
Uhlolisiso lwendlela iminenga eziphatha ngayo luye lwatyhila izithethe ezininzi ezibangel’ umdla. Ngokomzekelo, iminenga idla ngokunxulumana kakhulu, ihlala ingamaqela abizwa ngokuba zii<em>pods. Ezinye iintlobo zeminenga, ezifana neminenga ebulalayo, zineendlela zentlalo ezintsonkothe kakhulu ezineelwimi “zolwimi” ezikhethekileyo kwiipod ezahlukeneyo. Ngaphandle koko, Iminenga iyaziwa ngokufuduka imigama emide ngonyaka ngamnye, ifuna amanzi ashushu ukuze ikhulise amantshontsho ayo ngaphambi kokuba ibuyele kwiindawo ezityebileyo zokutya ezipalini..
Iminenga zizidalwa ezimangalisayo nezingaqondakaliyo, kwaye uphando olutsha ngalunye lutyhila iinkalo ezintsha zobukho bayo obunomdla. Zimele iyantlukwano kunye nokuntsonkotha kobomi kwiilwandle zethu kwaye zizizikhumbuzo eziphilayo zomsebenzi wethu wokukhusela nokugcina umhlaba wethu wendalo.
