I-walrus yase-Atlantic yisilwane esiyingqayizivele esihlala ezindaweni ezihlanzekile ngokwemvelo oLwandle iBarents. Ngeshwa, ithonya elibi kakhulu lesintu libonakala ngokucacile nalapha - okwamanje uhlobo lwesilwane lusengcupheni yokuqothulwa okuphelele, ngakho-ke lufakiwe kwiRed Book. Bhekisisa lezi zinombolo ezesabekayo - kubantu abayi-25,000, kusele ama-4 000 okwamanje.Izindawo lapho kuhlala lezi zilwane zingaphansi kokuvikelwa okuqinile. Kodwa-ke, ukukhula kwabantu kuhamba kancane kakhulu.
Lezi zilwane zihlala emihlanjini emincane ehlakazekile, engathintani nhlobo. Ukwehla okukhulu kwamanani kungenxa yokudoba okungalawulwa nokho, njengakwezinye izikhathi.
Incazelo yezinhlobo
Idatha yomzimba mayelana nalolu hlobo incane kakhulu, kepha kukhona imininingwane ethile. Kuyisilwane esikhulu esinesikhumba esiminyene esinsundu. I-Atlantic walrus yesilisa ingamamitha ayi-3-4 ubude futhi ingaba nesisindo esingamathani amabili. Kepha ngokuqondene nabamele uhlobo lwesifazane, bangakhula ngobude kuze kufike kumamitha angu-2.6, futhi ubukhulu abudluli ithani elilodwa. Inhloko ye-walrus incane, inamazinyo amade namehlo amancane. Ubude bokuchofoza bungaba yingxenye yemitha. Kulokhu, amabamba nawo ayasebenza - asika kalula iqhwa, asize ukuvikela indawo yawo kanye nomhlambi kubaphikisi. Ngaphezu kwalokho, i-walrus ingabhoboza kalula ibhere elisendaweni emhlophe ngamazinyo alo.
Ngaphandle kokukhuluphala okukhulu nesisindo esikhulu kakhulu, lolu hlobo lwesilwane lunemininingwane eyodwa encane, kodwa ebaluleke kakhulu - amadevu. Zakha izinwele ezincane ezingamakhulu amaningana kodwa ezinzima ezisiza ama-walrus ukufuna ama-molluscs emanzini naseqhweni.
Indawo yokuhlala eyi-walrus yase-Atlantic yi-ice floe. Ngokuqondene ne-sushi, nasi lesi silwane esikhulu sizizwa, ukusibeka kahle, singakhululeki. Ngenxa yokukhuluphala kwabo kanye nesisindo esikhulu, bamane nje abathandi ukuhamba emhlabeni - bangasebenzisa kuphela amaphiko ama-4 ukunyakaza.
Ummeleli omkhulu we-Arctic udla kuze kufike kumakhilogremu angu-50 okudla ngosuku. Leli nani lilungele yena. Ukudla kusekelwe kuma-crustaceans nama-molluscs. Kepha, kunobufakazi bokuthi uma kungekho ukudla, i-walrus ingahlasela ngisho nezimpawu zezingane.
Umjikelezo wokuphila
Ngokwesilinganiso, i-walrus yase-Atlantic iphila iminyaka engama-45. Akunakuphikwa ukuthi phakathi nesikhathi samanani amakhulu, isikhathi sokuphila besiside ngokwengeziwe. Ukuziphatha kwesilwane kuyaxaka - kukhula kancane. I-walrus ingabhekwa njengomuntu omdala eminyakeni engama-6-10 kuphela emva kokuzalwa. I-walrus ayikwazi ukulala kuphela, idle, kepha futhi i-snarl, yenza imisindo eqondakala kuphela kubantu abafanayo. Kuyaphawuleka ukuthi lolu hlobo lwesilwane luyakwazi ukukhonkotha.
I-walrus futhi "inethalente" impela - ngesikhathi sokukhwelana, yenza imisindo ekhethekile efana kakhulu nokucula okuzwakalayo. Akubona bonke abamele umhlaba wezilwane abanesici esinjalo sokuheha abesifazane ngokuzala.
Ukuthwala umbungu ngemuva kokukhulelwa kuhlala isikhathi eside ngokwanele - unyaka wonke. Ingane yondliwa iminyaka emibili futhi umama ayiyishiyi ize ikhule ngokugcwele. Ukuzalwa kwenzalo kwenzeka njalo eminyakeni emi-3-5. Empeleni, umhlambi wakhiwa ngezinsikazi namazinyane.
Indawo eyintandokazi yokuhlala kwamaphiko uLwandle lwaseBarents nolwandle lwaseKara. Futhi, isilwane singatholakala emanzini oLwandle Olumhlophe. Ngobulungiswa, kufanele kuphawulwe ukuthi ukwehla okukhulu kwenani lalezi zinhlobo zezilwane kungenxa nje yokudutshulwa kwabantu abaningi ngenxa yokudoba, kodwa kungenxa yokuthuthukiswa komkhakha kawoyela - amabhizinisi akule mboni angcolisa indawo yemvelo ye-walrus.
