indlela yokuphila

Beluha (ihlengethwa) uncamela enihlala amaphakethe, nakho ezakhiwe ngamaqembu amancane amaningana is, ababebalelwa eziyishumi ukuze izingalo eziyikhulu namashumi izilwane. Entwasahlobo, ezincelisayo ukubhukuda osogwini olusenyakatho abandayo enyakatho, lapho kwenziwe yonke inkathi efudumele, njengoba kulesi sikhathi sonyaka e angajulile wathola eziningi izinhlanzi ezihlukahlukene.

Ngalesi sikhathi ofanayo amahlengethwa molt iqala, phakathi kwesikhathi lapho ungqimba engenhla efile amaslayidi isikhumba, eziyingxenye esemqoka enezinto.

Lapho ezinzima kuyothi ayisibonelo ngoba amakhaza Arctic whale white (ihlengethwa) eshiya ezindaweni ezisogwini kanye oseyili ukuze izindawo lapho sebuningini ukukhukhuleka ice aqoqana.

Ngaphansi kwamanzi ezincelisayo ngaphandle komoya kungaba esiphezulu isigamu sehora, futhi ikakhulukazi kufika njalo ngemva kwemizuzu emibili. Aholwa evuthiwe ukuzwa izitho noma bezibona chemical futhi kungokoqobo, esisogwini ebusweni ulimi. Abakwazi ukuzwa Izigwedlo phezu kwamanzi, saphinde esekude yokwanda amagagasi ice kanye nezinye imisindo eziningi ebaxwayisa esondela ingozi.

ukudla

Belukha (Ihlengethwa) - isilwane, ukuzenzela ukudla esebenzisa ukuzingela lapho lezi ezincelisayo ukuza ngamaqembu amancane. yimpango yabo kukhona cod ikakhulukazi polar, capelin, izimpethu, flatfish, cephalopods, cod nesafroni, izimbaza, ama-cod nezinye kwezinhlobo zezinhlanzi amancane naphakathi.

ukukhiqizwa kabusha

Mate Beluga ngokukhethekile ezindaweni ezisogwini ngamanzi afudumele, okuyinto futhi zijulise azo. Ngakho-ke, inzalo yabo bazalwa ikakhulu ekwindla kanye entwasahlobo. Ukukhulelwa zesifazane ihlala okuyisilinganiso sabangu-izinyanga eziyishumi nane, okwathi ngemva kwalokho waba umuntu ozalwa osayizi ingane lafinyelela ubude 1.5 m futhi enesisindo 75 kg. isikhathi lactation we Beluga ihlala eminyakeni nesigamu, lapho ubisi yena feeds cub wakhe.

Lezi zilwane ukufinyelela izinga lokuzala ngeminyaka emihlanu, futhi ulahlekelwe ikhono qhubeka hlobo engamashumi amabili. Ngesikhathi esifanayo bahlala endaweni ethile, engakayihlanganisi iminyaka engu amane.

ingozi

Dolphins ezibhekwa beyizitha polar bear and whale, kukhona izilwane ezidla ezinye enamandla.

Njengoba nje kwenza umkhoma ezimhlophe pokes kwenhloko yayo, ngesikhathi esifanayo enamandla futhi uzipho stuns wakhe buhlungu eqinile. Ngemva kwalokho nebhere uthola umzimba equlekile phezu eqhweni futhi udla kuwo.

Isitha kwalezi zilwane yesibili futhi musa khumbulani ukuba ukukuxoxela obukhulu yabo amafutha ungqimba. Ngakho-ke, killer nama ungaphuthelwa ithuba lokuhlasela amahlengethwa kwamanzi. Beluga yokuphunyuka umzingeli okunjalo akunakwenzeka, njengoba aphinde abhukude abuyele kabili kancane kuka umhlaseli.

ezithakazelisayo ukwazi

Ngokungafani nezinye nabazala bayo kule isilwane iyakhiwa imisipha kahle ebusweni, ukuze ongabonisa imizwelo yabo Beluga (ihlengethwa). Photo ngesithombe yalezi ezincelisayo ziqoshwe khona, ukuhleka, ukujabulela ngisho ukukhombisa asenyanya ngayo yiluphi uhlobo yokunganakwa.

Nge -Latin igama lezi zilwane ngokuvamile lihunyushwa ngokuthi "ihlengethwa engenamaphiko" ngoba abazange babe fin ngemuva.
