Phoca sibirica - nerpa - nesihlobo esiseduze salowo lwezimpawu ringed abahlala e-Arctic Ocean. Phoca sibirica kufakwe umndeni zamanzi. Ezincelisayo Zasolwandle iBaikal emelelwa eyodwa lolu hlobo kuphela. Kulokhu, umsuka Phoca sibirica akucaci kahle kuze kube manje. Nge imfihlakalo indlela nerpa uvele on echibini, kuba legend mayelana Umhubhe ongaqondakali, wedlula e-Arctic Ocean. Kodwa-ke, kunoma yisiphi isiteshi cha. It is Nokho babekholelwa, ukuthi lesi silwane esincelisayo singene echibini ohlelweni emfuleni "Yenisei-Angara" Ice Age.

Ebusika, lesi silwane akafikanga ebusweni. Breathing esincelisayo e airhole elalizokwakhiwa e ice mncane. Ekupheleni kuka-ubusika eliqinisa phezu ice. Nokho, usengozini njengoba ebulawa abazingeli.

IBaikal uphawu lenzelwa cishe wonke amanzi echibini. Nokho esincelisayo abahlala endaweni irregularly. Inani elikhulu labantu ebonwe iBaikal Ephakathi (cishe isigamu sezindela kuso sonke isibalo sabantu), kanye esempumalanga (cishe ingxenye eyodwa kwezintathu). I yindawo yokuzalela ezisemqoka ezilandelayo: Cape Sagan, AAP Bay, Cape Khoboy. Nokho, endaweni Intandokazi nerpa kubhekwe Ushkany Islands. Akulona Iqembu elikhulu kakhulu labantu atholakala emadwaleni elingasogwini engxenyeni esenyakatho ye-mpumalanga yesifundazwe headlands enamadwala.

uphawu Adult Baikalian camera nge aminyene nezinwele ezimfishane. On the ngemuva umbala izinwele sinombala-grey, umbala esiqinile ngesiliva tinge-olive-bluish. Boca nesisu mammalian ukuxegiselwa. Warm hhayi zamanzi ezinoboya, futhi ongama amafutha isitokwe, ukushuba ungqimba okungaba kuze kube ngamasentimitha nambili. Fat ivikela hhayi kuphela ngokumelene frost, kodwa futhi ngenxa yokulimala ngephutha, kwandisa buoyancy aqoqana amandla. Ngo abantu evamile plump ke baze babe amaphesenti angu ayisihlanu isisindo ingqikithi.

Ngokwesilinganiso, nerpa ukala ngamashumi ayisihlanu noma ayisithupha ngamakhilogremu, nge ubude ngesikhathi esifanayo ngayikhulu namashumi ayisihlanu ngamasentimitha. Nokho, kukhona izinhlanzi ngokwanele ezinkulu, nesisindo eziyikhulu kuya amakhilogremu anamakhulu mabini. Ubude ngesikhathi esifanayo sebezofunda nekhulu namashumi ayisikhombisa nanye namashumi amasentimitha ayisishiyagalombili.

Young (nerpyata) bazalwa noboya emhlophe. Lokhu kwenza kwabo ongabonakali eqhweni. Labelwe amehlo abamnyama kuphela.

Yokucashisa uphawu, ngokuvamile kuphela, ngezinye isabelo saso kude nasolwandle, eqhweni iphakethe. Kulokhu, e isilwane ngaphandle imithombo eyinhloko cishe unezinyanga amabili ngaphezulu.

Iqhwa ethubeleza lwezimpawu ukwenza umphandu. Lapho abesifazane abelethe ngoMashi lwezimpawu. Kusukela den ube kuphela eyodwa okukhipha-okokufaka - emanzini. Umuntu omdala uyazenwaya izinzipho zakhe kulo lonke ebusika, ekuvimbeleni okokuqandisa. ingane Born uqala zigweda iqhwa. Kodwa kuye, lo inotiyela kuyingozi ngoba can Peck iqhude.

ukuzwela okukhulu izinwele phezu kwamehlo ne lip engenhla. Ngosizo lwabo uphawu ngamakhasimende, nabo basize ukubamba izinhlanzi.

Nares esincelisayo ethulwa ngesimo Slots ezimbili. basuke ivaliwe futhi igcinwe avaliwe uma isilwane emanzini. Amanzi Bavala kanye izindlebe, okuyinto ivezwa izimbobo ezincane njengoba elula. Kufanele kuqashelwe ukuthi nerpa Onendlebe emangalisayo. Ngakho, ngaphansi kwezimo ezinhle sezulu isinyathelo womuntu, kungaba ukubamba at ibanga amamitha angamakhulu nane, anamakhulu mabini. Nge evumayo umoya uphawu ngeke ngiwahogele iphunga indoda nengxenye amakhilomitha amabili.

I share eyinhloko yokudla uphawu kukhona golomyanka-goby izinhlanzi. Abanalo ukubaluleka wokuhweba abantu. On isifanekiso isilinganiso izinhlanzi ibadla bebathathu amakhilogramu ngosuku.

Kufanele ukuthi izitha zemvelo e iBaikal seal akukho. Kuphela indoda. Population kwehliswa yalokho ukuzingela njengoba Umzingeli, futhi amalayisense. Ngaphezu kwalokho, kukhona futhi amakhemikhali angcolise echibini, okuyinto sithinta ukwehla abantu abaningana.
