li-cetacean li lula kae
Sebaka sa li-cetaceans ke tikoloho ea metsing. Ntle ho eena, letlalo la bona le ka omella mme ba ka shoa. Li-cetacean tse ling li lula metsing a potang metsi, mohlala, leruarua la beluga (Delphinapterus leucaskapa leruarua la narwhal (Monodon monoceros), kahoo li ikamahanya le maemo a batang haholo. Tse ling li ajoa haholo libakeng tsa tropike, joalo ka leruarua le hlatsoitsoeng ka nako e telele (Melas ea Globicephala) le leruarua le hloloang hakhutšoane (Globicephala macrorhynchus).
