Isalathiso seBaikal

I-Phoca sibirica - uphawu lwe-Baikal - isisondlo esisondelene nesitywina esicinciweyo esihlala e-Arctic Ocean. I-Phoca sibirica ifakwe kwintsapho yeempawu zokunyaniseka. Izilwanyana zaseMammalian zaseLake Baikal zimelelwe yintlobo enye kuphela. Nangona kunjalo, imvelaphi ye-Phoca sibirica ayilucacisiwe kuze kube ngoku. Ngenqabana malunga nendlela uphawu lwamaBaikal olubonakala ngayo echibini, kukho umlando malunga nomsele ongacacileyo owela i-Arctic Ocean. Kodwa, ke, akukho mzila. Kukholelwa ukuba isilwanyana esidlwengulwayo singena echibini ngasemlanjeni "Yenisei-Angara" ngexesha leqonga.

Ebusika, isilwanyana asifihla phezulu. Uphefumula isilwanyana esilungileyo kwiprodushiny, esakhiwe kwiqhwa elincinci. Ekupheleni kwebusika, itywina iyavela kwiqhwa. Ngelo xesha, usengozini yokubulawa ngabazingeli.

Isalathiso seBaikal sisasazwa ngokubanzi kulo lonke ummandla wamanzi echibi. Nangona kunjalo, izilwanyana zihlala kwindawo engafaniyo. Inani elikhulu labantu babhalwa kwi-Middle Baikal (malunga nesiqingatha sabantu bonke), kunye nxalenye yaso empuma (malunga nesithathu). Ii-rookeries eziphambili zilandelayo: Cape Sagan, Aai Bay, iKapa Khoboy. Nangona kunjalo, indawo endiyithandayo yinqwaba yaseBaikal yiiIshkany Islands. Amaqela amaninzi abantu afunyanwe kumanxweme enxweme kummandla osenyakatho-mpuma wee-capes zamatye.

Isalathisi esingumdala seBaikal sihlanganiswe neboyile emfutshane. Emuva, umbala weenwele unobumba obunqabileyo obunqabileyo, i-monophonic ne-silvery kunye ne-gray-gray tinge. Amacala kunye nesisu ngesilwanyana esilwanyana esilumkile. Isitywina asifudumala ngobushushu, kodwa sisinxweme esincinci samanzi, ububanzi obunokuthi bufike kuma-centimitha angama-12. I-Fat ikhusela kuphela kwi-congratulations, kodwa kwakhona kwenzakala ngengozi yengozi, iyanda ukwanda, iqokelela amandla. Kubantu abondliwe kakuhle, kukufikelela kuma-50 ekhulwini weesisindo.

Ngokomyinge, iziqwenga zeBaikal zixakeke malunga neekhigramgram ezingamashumi amahlanu ukuya kwamashumi mathandathu, zibe nobude beesentimitha ezilikhulu namashumi amahlanu. Nangona kunjalo, kukho iimbonelo ezinkulu, ubunzima obunokufikelela kwikhulu elinamanci mahlanu eekhigram. Kule meko banokude malunga neekhilomitha ezilikhulu elinamanci asixhenxe anesibhozo nesibhozo.

Iibhubhu (i-torso) zizalwe ngobumhlophe obomvu. Ngenxa yale nto ayibonakali kwikhephu. Amehlo amnyama kuphela aphumayo.

Iimpawu zokuqhaqhayisa, njengomthetho, zodwa, kwisiqendu sabo, kude nxweme, kwiqhwa elincinci. Ukongeza kwimiba ephambili, kukho malunga nezilwanyana ezilisiweyo ezingamashumi amabini ezilwanyana ezilwanyana.

Kwikhephu idiphozi, izibindi zenza umdaka. Apha, amabhinqa ngo-Matshi uzala. Ukusuka kwinqaba kukhona kuphela ukuphuma-ukungena-emanzini. Umzekelo omdala umakrokra kuwo wonke ubusika ngeminwe, engavumelekanga ukuba afakelwe. Ithole elizalwe liqala ukumba ekhephu. Kodwa kuye, ukufikelela kummandla kuyingozi, njengokuba izikhwebu zinokumkhahlela.

Izinwele ngaphezu kwamehlo kunye nemilomo ephezulu zibuhlungu kakhulu. Ngoncedo lwabo, itywina lixhomekeke kuyo, bancedisa ukuloba.

Amacinci esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana esilwanyana Xa isilwanyana singena emanzini, zivaliwe kwaye zigcinwe zivaliwe. Amanzi nawo avala iindlebe, ezinikezwa ngendlela yemigodi emincane. Kufuneka kuqatshelwe ukuba iimpawu zikaBaikal ziyaziwa ngokuvavanya kakuhle. Ngoko, ngeemeko zemozulu ezintle, isinyathelo somntu sinokubamba kumgama wamakhulu amabini ukuya kumakhulu amane emitha. Ngomoya ococekileyo wesitywina, iphunga lomntu livalelwa ngeekhilomitha kunye nesiqingatha okanye iikhilomitha ezimbini.

Isabelo esiyinhloko sokutya kwamatywina senziwa yintlanzi ye-golomyanka-goby. Abenayo ixabiso lentengiso kubantu. Ngokomyinge, umntu udla le ntlanzi kwiikhilogram ezintathu ngosuku.

Kufuneka kuthethwe ukuba uphawu lweBaikal alukho intshaba yendalo. Umntu kuphela. Ukunciphisa ubemi kubakho ngenxa yokuzingela kokubili ukuzingela kunye neelayisenisi. Ukongezelela, kukho ukungcola kwamachiza echibini, okuchaphazela nokunciphisa inani labantu.
