I kwabantu of zokuhlala lezi ezilwaneni ezidla ezinye izilwane kuyinto engalingani kakhulu. Ngokwemvelo, kulapho lapho, lapho amanzi afudumele futhi elinamanzi amaningi nenala yokudla, okungukuthi ugu.

I kwabantu labantu izilwandle zomhlaba

Inombolo enkulu zinhlobo nezinhlobo oshaka basuke bagxila amanzi ashisayo babesuke futhi enkabazwe. Mayelana 80% ezidla zasolwandle abahlala lapha bahlala ezingqimbeni surface a engekho ngaphezu kuka-200 m ukujula. Lokhu kungenxa yokuthi la manzi zinothile ukudla.

Ngokulingene ulwandle efudumele namanzi olwandle is ingasaphathwa ugcwale lezi zinhlanzi -% 16 kuphela kashaka Imininingwane ophilayo emhlabeni.

Futhi abandayo kwezilwandle Arctic iyivela kancane kakhulu. Ngakho-ke, zimbalwa kakhulu uma ibona izilwane eziyingozi. Bebhukuda kulezi zindawo kuphela nezinyanga zasehlobo ezifudumele. Lezi zinhlobo abandayo-ukubekezela kukhona polar (Greenland) kanye ushaka elikhulu.

polar ushaka

It kungokwalabo bohlobo Somniosidae noma Pryamorotye. ushaka Polar omele kunazo zonke kwezingu-squaliformes lamabutho. Abanye abantu kwalesi silwane ukufinyelela ezingaphezu kuka-6 m ubude futhi zinesisindo esingaba 1,000 kg. Kodwa ichthyologists, ososayensi bakholelwa ukuthi lokhu kwenziwa yini umkhawulo - 8 m ubude nesisindo amathani 2 kungenzeka. Ngokuvamile, Ubukhulu ezinjalo, alisebenzi futhi akusho ngempela ukulingana isithombe lapho bonke zijwayele, okungukuthi i umhlaseli esinomdlandla, asheshe futhi ononya. ushaka Polar ngokuphelele non-nolaka, ngisho uma lungena inethiwekhi, ukuthi iziphatha ngomoya ophansi, njengomuntu log.

Kubukeka Okuqukethwe akuzwakali futhi akuthandeki: Ibala lesikhumba - othini lokuphotha emise, umbala - kusuka konsundu ukuba brown namabala amnyama lokuyibubende chithi saka emzimbeni.

Ngenxa yalesi sizathu kuphela isihloko le nhlanzi enkulu, kusobala ukuthi butholakala emanzini abandayo Atlantic futhi Arctic izilwandle. Habitat oshaka ebanzi ngokwanele.
