Izinyoni zasemanzini yizinyoni ezikwazi ukuhlala ngokuzethemba ebusweni bamanzi isikhathi eside. Njengomthetho, bahola impilo yasemanzini, okungukuthi, abavamile ukuphuma emhlabeni. Isisekelo sokudla kuleli cala sakhiwe izinhlanzi nezakhamuzi ezincane zasemanzini - ama-crustaceans, ama-plankton, izinambuzane.
Isici esiyinhloko sazo zonke izinyoni zamanzi ubukhona bezingqamuzana phakathi kwezinzwani. Ngenxa yazo, le nyoni iyakwazi ukuhamba emanzini, futhi lapho, ithuthukisa ijubane elifanele. Futhi, ulwelwesi lusetshenziselwa ukunika amandla ukuhamba ngokushesha ebusweni bamanzi.

Isiphetho
Izinyoni zamanzi zifaka inani elikhulu lezinhlobo zezinyoni. Mhlawumbe edume kakhulu kubo amadada, ama-swans namahansi, ngoba phakathi kwabo kukhona ama-subspecies wokugcinwa kwekhaya. Iningi lezinyoni ezikwazi ukubhukuda emanzini alitholakali emehlweni esakhamuzi esivamile. Ukuze uzibone, udinga ukuvakashela imizimba yamanzi, ngaphezu kwalokho, evame ukude futhi engafinyeleleki.
Ngaphezu kokudla okuvamile kanye nolwelwesi emilenzeni, zonke izinyoni zamanzi zifakwe indlala ye-coccygeal. Uba nemfihlo ekhethekile ethambisa izimpaphe. Luhlobo lwamafutha olwenza izimpaphe zingangeni manzi futhi lwandisa ukufudumeza okushisayo. Isendlalelo esithuthukisiwe sesikhumba esingaphansi sibuye sibe nomthelela ekugcineni ukushisa. Yingakho izinyoni zikwazi ukubhukuda noma emanzini abandayo kakhulu, okuvame ukufakwa eqhweni.
Ngaphandle kokutholakala kokudla okuvamile, izinhlobo zezinyoni zamanzi aziphazamisani futhi azinomncintiswano we-interspecific. Lesi sigaba senziwa ngenxa yezindlela ezahlukahlukene zokuthola ukudla, kanye nokujula okuhlukile lapho kutholakala khona. Ngokwesibonelo, izinhlanzi zasolwandle zibamba izinhlanzi lapho zindiza, bese kuthi amadada atshuzela ezinzulwini ezingemuva kwawo.
