Mvuu mukaka - chokwadi kana ngano, ndezvipi kufungidzira uye kutonga

Mhuka iboka remhuka dzinosanganisira nhamba huru yemarudzi. Vanogara munzvimbo dzose, vanogara mumamiriro ekunze akasiyana. Kusiyana kwavo kwakakura. Ichi chinyorwa chinotsanangura maitiro eimwe yemhando, iyo, mvuu.

Mamiriro akasiyana ekirasi yemhuka dzinoyamwisa

Zvose zvinoyamwisa zvine maitiro akafanana, nekuda kwazvakabatanidzwa mukirasi ino. Chimwe chezvinyorwa zvakakosha nekuda kwekuti zita rekirasi rakareba ndiko kukwanisa kupa mukaka kudyisa vana.

Hunhu hwemhuka dzese dzinoyamwisa:

1. Mhuka dzine ropa rinodziya.
2. Kugona kupa mukaka wekudyisa vana.
3. Kuvapo kwemvere dzemakwai. Mune mamwe marudzi, yakanyanyisa, ine vhudzi refu, uye zvakasiyana, kune chivharo chisingawanzoitiki, chine vhudzi duku, risingaonekwe.
4. Zvimiro zvechimiro chenhengo dzemukati, zvinosanganisira chimiro chemapapu, moyo, digestive, genitourinary systems.
5. Kubereka vana, kune imwe nhengo yakasiyana yehutano hwekubereka mumadzimai - chibereko.
6. Kuonekwa panguva yekuzvitakura kwekutenderera kweplacental.
7. Nhengo dzekunzwa dzine chimiro chakaoma kwazvo, kuwanda kwacho kwakanyatso kudyidzana nekugara kweimwe neimwe mhando.
8. Kuvapo kweziya uye sebaceous glands.
9. Yakanyanya kurongeka chimiro chetsinga.
10. Hukama hwakaoma hwevanhu mumwe nemumwe.
11. Kuchengeta vana dzimwe nguva kunogona kurova kwenguva yakareba.

Sezvambotaurwa, mhuka dzinoyamwisa ndiro boka rinonyanya kuzivikanwa remhuka. Vazhinji vavo vanogara African continent, inoshamisa nekusiyana kwayo. Kune mamwe marudzi akasiyana zvakanyanya. Izvi, zvechokwadi, zvinosanganisira mvuu.

Hunhu hwemvuu

Rudzi urwu rwagara rwuchikwezva vanhu. Mvuu dzinotungamira semi-aquatic mararamiro ari mhuka huru huru, gobvu zvakakwana. Vanogara mumadziva emvura matsva chete. Zvipfuwo zvavo dzimwe nguva zvinogona kushamisa muhukuru. Chii chinonzi rudzi urwu? Ndeapi maitiro ayo?

1. Vanoshambira vakanaka uye vakasiyana-siyana, zvisinei nemuviri wakakura, huremu hwemurume mukuru hunogona kusvika kusvika matani mana, ndeimwe yemhuka hombe.
2. Mvuu haina makushe, pamuromo pane ndebvu refu-vibrissae.
3. Mazino nemazino zvinokura muupenyu hwose.
4. Ihama dzemawhale, dzaimboonekwa sehama dzenguruve.
5. Vanokwanisa kubata kufema kwavo pasi pemvura kwenguva yakareba semaminitsi 5-6.
6. Kana uchimhanya, kumhanya kwavo kunogona kusvika kusvika 50 km / h.
7. Mvuu dzinodikitira zvakanyanya, dikita radzo rine hunhu dzvuku.
8. Vanogara mumhuri dzine mukono mumwe chete uye hadzi dzinenge 15-20 dzine vana.
9. Kusununguka kunogona kuitika zvose panyika uye mumvura.
10. Huremu hwemwana achangoberekwa hunogona kusvika 45 kg.
11. Dzinoburitsa magasi nemuromo, kubva padivi panogona kuita kunge mvuu yoyeva.
12. Mararamiro avo ane basa rakajeka rezuva nezuva, vanosarudza kurara masikati, uye usiku vanoenda kumahombekombe kuti vadye.
13. Herbivores, chikafu chayo chiri mumvura uye yemahombekombe.
14. Mvuu imhuka ine hasha inokwanisa kudzivirira vana vayo kubva kune chero zvikara.

Vanhukadzi vanaamai vane hanyavachishingaira pamwe chete navana vadzo. Kubata pamuviri kunotora mwedzi misere, somugumisiro, mwana akaumbwa zvakakwana anoberekwa, anokwanisa kumira pamakumbo maawa maviri mushure mokuberekwa.

Mvuu, sevamiriri vese vekirasi iyi, vanodyisa vana vavo nemukaka. Kune ngano dzakawanda, fungidziro uye mitongo maererano nenyaya iyi. Semuyenzaniso:

1. Mukaka werudzi urwu mupingi.
2. Mukaka wemvuu unogona kuerekana washanduka pink.
3. Rudzi rwemukaka haruna kunyanya kusiyana nemukaka wemukaka wedzimwe mhuka.

Zvimiro zve physiology yemvuu

Sezvo mhuka iyi inogara mumamiriro ekunze anopisa, yakamanikidzwa kuenderana nekugara uku. Izvi zvinotsanangura dikita rakawanda remvuu. Matumbu edikita anoburitsa hipposudoric acid, inogona kusanganiswa nemukaka wemukadzi panguva yekudyisa. Somugumisiro weizvi, kemikari inoitika, uye mukaka unowana ruvara rwepinki.

Mukadzi nguva dzose anobereka mwana mumwe chete. Mvuu ichangozvarwa uye pwere imhuka iri nyore kudyiwa nezvikara, zvinoti shumba, mapere, imbwa dzefisi nembada.

Hukama hwemvuu kune mumwe nemumwe

Hippo Possess yakanyanya kukudziridzwa tsinga. Vane maitiro avo.

Idzi imhuka dzemombe, dzichicherechedza kuzviisa pasi kwakajeka mukati memhuri. Varume vechidiki vasati vabva zera vanowanzoita mapoka. Hadzi diki dzinogara dziri muboka revabereki. Kana, nokuda kwechimwe chikonzero, mvuu hono yakasiyiwa isina hadzi yayo, ipapo inofanira kugara yoga kusvikira yaumba imwe itsva.

Bhehemoth ndizvo mhuka dzine hasha dzakasimba, vachitwasanudzana zvisina tsitsi panyaya dzehadzi kana kutonga muboka. Kunyange mumhuri yake pachake, mutungamiri wechirume anogona kurangwa zvakaomarara nevakadzi vane vacheche kana akavapaza asina kukumbira.

Mhuka idzi dzine inzwi guru rinoyevedza, dzichirishandisa kutaura nevamwe vanhu uye kutyisidzira vanopikisa.

Mvuu vabereki vakanaka uye vane hanya vanodzidzisa vana vavo huchenjeri hwose hwehupenyu hwavo. Kubva vachiri vadiki vanoda kunyatsoteerera, kana mucheche akaramba uye akasateerera, chirango chakakomba chinomumirira. Saka mvuu dzinodzivirira vana vadzo, chinova chimedu chinonaka chezvikara zvakawanda. Zvinoshamisa ndezvekuti, kutanga kubva pazuva rechipiri rehupenyu hwake, mvuu inokwanisa kushambira zvakanaka, ichitevera amai vake kwose kwose.

It territorial mhukavanoda kutsungirira, kuchinja kupi nokupi kunokonzera kurambwa mavari. Munguva yekusanaya kwemvura, apo mvura inenge yadzika, mapoka makuru emvuu anoumba. Apa ndipo panomuka kunetsana kwakawanda pakati pevanhu. Vanowanzo tara miganhu yavo, nokuda kwezvinangwa izvi vanoshandisa marara avo, vachiaisa neimwe nzira. Vesainzi vave nenguva vachiona kuti mvuu dzinouya kumahombekombe dzichishandisa nzira dzadzo.

Zvinosuruvarisa, ikozvino nhamba yemvuu yakaderera zvakanyanya. Muzana remakore rechimakumi maviri, mhuka idzi dzaive chinhu chakakurumbira chekuvhima, izvo zvakanyanya kuderedza huwandu hwavo.

Maererano nemasayendisiti, rudzi urwu rwakadaro zvinoshamisa biological plasticity, izvo zvinoreva kuti pane mukana wekudzorera zvipfuwo zvavo uye kuchengetedza rudzi urwu runoshamisa rwemhuka dzinoyamwisa.
