Li-whale li lula hokae?

Li-whale li ka fumanoa maoatleng 'ohle a lefatše. Mefuta e meng e kang maruarua a bolaeang, maruarua a maputsoa, ​​kapa maruarua a humpback a tletse hoo e ka bang maoatleng 'ohle, a mang a hlaha feela libakeng tse itseng.

Ho na le mefuta efe ea maruarua?

Baholo-holo ba maruarua e ne e le liphoofolo tse anyesang tsa lefatše tse ileng tsa fallela metsing lilemong tse ka bang limilione tse 50 tse fetileng 'me butle-butle tsa fetoha liphoofolo tse phelang metsing tse phethahetseng.
