Chisimbiso Common ndeimwe mashoma vagere yedu, izvo vanoda inodziya chando. Kutaura zvazviri, ndicho chikonzero vanogona kuwanikwa chete kure kunzvimbo nesinou. Nokuda kwaizvozvi yakareba, masayendisiti kugona kudzidza mhuka idzi zvakanaka. Anongove zvino kuti mberi mberi kukuru, isu tazarura upenyu anoshamisa mune zvakasikwa zvakatipoteredza.

Makwapa, kana vanhuwo, chisimbiso: dzinogarisana

Vamiririri zvose mhando iyi rudo kutonhora kwekunze. Saka, vanenge vose kwezvisimbiso anowanikwa kumadokero uye nechokumabvazuva kumatunhu kweArctic Ocean. Ndizvo avo siyana kunosvika kuGungwa Bering, Botfortovo uye chukchi makungwa. Mukuwedzera, vanogona kuwanikwa yegungwa pamusoro Zimbabwe neGungwa Barents.

Species pfumbu chisimbiso

Kusvika panguva vanhu chiteshi zvisimbiso ane vanenge 500 zviuru. Vanhu. Mhuka dzose dziri chaizvo akafanana mumwe, asi panguva imwe chete, masayendisiti akaratidza zvinoverengeka anokosha subspecies. Kazhinji, munhu kupatsanura akadaro chokuita dzinogarisana. Zvisinei, pane zvimwe kwokunze kusiyana-siyana dzaitongwa.

Saka, chisimbiso nevakawanda rakakamurwa zvinotevera subtypes:

• East Atlantic - ndicho, anorarama achitevedza coastlines yeNorthern Europe uye Western Asia.
• West Atlantic subspecies - inoremekedzwa rinenge rose nechokumabvazuva North America.
• Pacific mapoka mhuka idzi vagere kumadokero chikamu North America.

• Chisimbiso chitsuwa - kugara duku nomunda, akapararira mugungwa pedyo eAsia.

chitarisiko

Tinozivei pamusoro zvokunze features, ine chisimbiso nevakawanda? Photos zvemhuka akaita munzvimbo dzose kweArctic, vakabvumira masayendisiti kuongorora zvose mhando yose. A kuziva chokwadi: anenge ose subspecies ose chisimbiso zvavo Kutarira akaita purebred hama. The chete kunze ndiwo specimens Pacific kuti vari zvishoma kupfuura zvavo kukura muviri pamwe.

Asi shure kune panze. Ruvara zvisimbiso ingasiyana kwoupenyu hwavo. Zvisinei, vakawanda mbava ruvara kunosiyana-siyana pakati wachena kana yakatsvukuruka mashava. Panguva iyoyo kumativi muviri pemhuka ari runobva netsika akapararira rima makwapa. Zvikurukuru, imhaka pavo ichi mhando dzimwe nguva anonzi "madodzi madodzi".

Panyaya size, paavhareji vanhuwo chisimbiso anokura 1.8 metres. Muchiitiko chino, avo uremu kunosiyana-siyana pakati 150-165 makirogiramu. Zvinofanira kucherechedzwa kuti vakadzi vari nguva dzose zvinoenderana duku zvikuru pane varume.

Miitiro uye dzinogarisana

chisimbiso Common anoda kugara pamusoro matombo nemahombekombe mumhenderekedzo yegungwa. Panguva iyoyowo anoedza kudzivisa nyika ngaizaruke, kuti arege atambudzwe vatorwa. A kuziva ndechokuti, akasiyana dzepedyo dzavo, chisimbiso nevakawanda hakuiti tama. kare dzezvitsigiro panzvimbo imwe mhando iyi uye mashizha kana chete zvakakodzera chaizvo.

Kana zvokudya, mhuka iyi ndiyo zvikara chaidzo. Vanoronda kunyanya mvura, nekuti chinhu ichi - musha wavo. Sezvo zvavo vakasarudza mudukusa nimble hove: capelin, herring, safuroni kodhi, polar kodhi uye zvichingodaro. Zvisinei, kana hapana pfuma yakadaro, zvisimbiso vanogona nyore uye invertebrates.

kubereka chezvidhindo

upenyu About 5 gore varume kokutanga kufarira zvevakomana. Asi nhunzvi akure mhanyisa, vane bonde rinotanga 3 makore. Gestation kunotora 11 months. Panyaya iyi, chiedza anozvarwa mhuru imwe chete, chete zvisingawanzoitiki chaizvo nguva hadzi anogona kuita vaviri vechiduku.

Paavhareji, nemicherechedzo vanhurume kurarama makore anenge 25-30, iyo zvakajairika kuti mhuka dzavo. "Ladies" vakanga wakakomborerwa, sezvo avo kunonyanyisa zera kunosiyana-siyana pakati 35-40 makore. Masayendisiti anogona kunzwisisa hunhu Fani iyi, asi anoratidza kuti zviri chokuita nhengo dzokubereka basa.

Natural vavengi chezvisimbiso

Vazhinji vanodavira kuti muvengi mukuru zvinowanzoitwa mucherechedzo ndiye Bheya rakamira pachando. Mutsara uyu hachisi chokwadi zvachose. Pasinei chokwadi kuti toed chikara anokufarira chaizvo kunovhima dzizere mhuka, kubva muusungwa chete duku kesimba mhuka idzi ake kufa.

A ngozi zvikuru iri wakabvunzwa muurayi hove huru. Izvi zvomumvura zvikara munyika nekubwaira kweziso abate uye kudya gaping zvakatorwa nechisimba. Mukuwedzera, chete uchitsanya zvisimbiso anogona kutiza muurayi shato huru, uye ipapo, panguva chaiyo kutizira kumahombekombe.
