Letšoao la Weddell
Mofuta ona oa liphoofolo o ile oa reoa lebitso la ona ho molaoli oa leeto la indasteri ho le leng la maoatle a Antarctica (hape le na le lebitso la ho tlotla rasaense enoa) - James Weddell.

Litiiso tsa Crabeater
Letšoao la crabeater le tsejoa e le lona feela lelapeng la litiiso tsa 'nete. Ke mofuta oa litiiso o atileng haholo eseng feela ho ba lulang Antarctica, empa hape le hara ba lulang lefatšeng le pharalletseng. Ho latela likhakanyo tse fapaneng tsa bo-ramahlale, palo ea bona e fapana ho tloha ho batho ba limilione tse 7 ho isa ho tse 40.
Lebitso la liphoofolo tsena ha le amane ka letho le nnete, hobane makhala ha a kenyellelitsoe lijong tsa bona. Lianyesi tsena li fepa haholo-holo li-krill tsa Antarctic.
Boholo ba litiiso tsa crabeater, tse seng li fihlile ho batho ba baholo, li ka fihla bolelele ba lisenthimithara tse 220-260, 'me boima ba tsona bo fapana ho tloha ho 200 ho isa ho 300 kilograms.
Ho na le 'mele o molelele ebile o mosesane. Molala o motenya ebile o mosesane. 'Mala oa' nete oa boea ba tsona o bosootho bo lefifi, empa kamora ho fifala e ba bosoeu bo bosootho.
Litiiso tsa Crabeater li na le meno a latellaneng a scalloped-lumpy. Sebopeho sena se bolela hore li lekana hantle ebile li theha mofuta oa sefe e ba lumellang ho sefa lijo.

E na le mmele o otlolohileng o e lumellang ho tsamaea ka metsing ka potlako haholo ho feta litiiso tse ling. Sebopeho sa hlooho se bataletse, se tloaelehileng ho lihahabi tsa liphoofolo. Maoto a ka pele a malelele, e leng se amang le lebelo la motsamao ka metsing.
