NgwiniauPengwininindegewa bahari katikafamiliaSpheniscidae.Ndege hawa hawawezi kuruka angani lakini chini ya maji huenda kama “kuruka”. Kwa kweli, wanaishi baharini nusu ya mwaka na wanarudi nchi kavu ili kuzaa tu. Kwa kawaida ngwini ni weupe kwa kidari na tumbo na weusi kwa mgongo (aina yakamafleji). Huwakamatanduvi(krill),samaki,ngisina wanyama wengine wadogo wa bahari. Hata kama kwa kawaida ngwini huhusishwa nabarafuyaAntakitiki,spishi nyingi huyataga mayai yao kwa pwani za visiwa zenye miamba au ndani ya mashimo ambayo ngwini wameyachimba. Jike huyatagamayaimawili, lakini yule wa spishi zaAptenodyteshulitaga moja tu. Jike na dume huatamia mayai kwa zamu, lakini kwa kawaida kinda moja hutoka tu au kinda moja analishwa tu.Aptenodytes forsteri(Emperor Penguin) huzaa mbali na bahari juu ya barafu yaBara la Antakitiki.Dume hutamia yai wakati jike anapotafuta chakula cha kumpa kinda.
