Isingeniso: Ingabe Amaphengwini Angasinda Ngaphandle Kokudla?
Amaphengwini aziwa ngokubukeka kwawo okuhle nokuxakile, kodwa ukusinda kwawo endaweni enokhahlo nengalindelekile yase-Antarctic akuyona into ehlekisayo. Enye yezinselelo ezinkulu amaphengwini abhekana nazo ukuthola ukudla okwanele ukuze aziphilise wona kanye nenzalo yawo. Kodwa ingabe amaphengwini angaphila ngaphandle kokudla? Impendulo ithi cha, amaphengwini awakwazi ukuphila unomphela ngaphandle kokudla.
Amapenguin yizinyoni ezingandizi ezithembele olwandle ukuze zidle. Zidla ngokuyinhloko izinhlanzi ezincane, i-krill, ne-squid, futhi zijwayele ukuzingela nokubamba inyamazane ngaphansi kwamanzi. Ngaphandle kokutholakala kokudla okungaguquki, amaphengwini angashesha abe buthakathaka futhi angondleki, okuwenza abe sengozini yezilwane ezidla ezinye kanye nesimo sezulu esibi sase-Antarctic. Ukuqonda imikhuba yokudla amapenguin, ukujwayela ukushoda kokudla, kanye namazinga e-metabolic kubalulekile ekufundeni ukuthi ziphila kanjani endaweni yazo eyingqayizivele.
Ukuqonda Imikhuba Yokondla I-Penguin
Amaphengwini angabatshuzi abahle kakhulu nababhukudayo, okubavumela ukuba babambe izinhlanzi nezinye izilwane ezizingelayo ngaphansi kwamanzi. Zinezimo ezikhethekile zokuzingela ngaphansi kwamanzi, njengemizimba ehlelekile, amaphiko afana namaphiko, nezinyawo ezinezintambo. Izinhlobo eziningi zepenguin zidla izinhlanzi ezincane, i-krill, noma i-squid, kodwa ukudla kwazo kungahluka kuye ngendawo nesikhathi sonyaka.
Amaphengwini ngokuvamile azingela yedwa noma ngamaqembu amancane, esebenzisa umbono wawo obukhali ukuze abone inyamazane engaphansi kwamanzi. Bayakwazi futhi ukutshuza ekujuleni okukhulu futhi bahlale ngaphansi kwamanzi isikhathi eside, kuze kufike emaminithini angu-20 kwezinye izinhlobo zezilwane. Lapho sezibambile inyamazane yazo, isebenzisa imilomo yazo ukuze iyigwinye iphelele noma iyiklebhule ibe yizicucu ezincane. Ngokuvamile ukudla kwenzeka olwandle, kodwa ezinye izinhlobo zingase zibuyisele ukudla ematshwele azo emhlabeni. Sekukonke, amaphengwini angabazingeli abanekhono nabanekhono, kodwa basabhekana nezinselele uma kuziwa ekutholeni ukudla okwanele ukuze baphile.
