lintlha tse thahasellisang

1. Leoatle nyenyane ka ho fetisisa lefatšeng e sebakeng sa bobeli ka mor'a Pacific ea ka palo ea lihlekehlekeng tse ling tse sebakeng sebaka sa eona.
2. Metsi sebakeng seo ho na le ka sebopeho lona ke sehlekehleke kholo ka ho fetisisa lefatšeng (Greenland) le sehlopha sa lihlekehleke kholo ka ho fetisisa (Canada Arctic).
3. Ho fetisisa ea leoatle larileng ka tlas'a leqhoa selemo ho pota.
4. Har'a batšoaruoa ho ile ha sibolloa e sesang kholo ka ho fetisisa. E ne e bitsoa cyanogen, e tse ka bang peli limithara tse le bophara ba 'me tentacles ho fihlela ho limithara tse mashome a mabeli.
5. Hape o lula mona leoatle sekho ka leoto nako ya di emetse disentimitara ho fihlela ho mashome a mararo.
6. Mabōpong a leoatle nyenyane ka ho fetisisa ke e sa tloaelehang phoofolo - musk pholo.
7. Ka lebaka la sebaka ho futhumala ha 'me leqhoa botenya ba fokotswa haholo. E develops ka bothata bo tebileng tikoloho: metsi ho tswa ho glaciers qhibiliha oela maoatle, 'me boemo ba lona e tla tsoha. Haeba re nka hore glaciers tsohle li tla qhibiliha, boemong ba tla tsoha ka ho limithara tse tšeletseng.
