Pamwamba pa makutu mutu pabwino ndi mphuno kuti kutseka basi, inu nyama kugwera m'madzi.

zimphona zamiyendo Inayi

Nyama zimenezi amakonda kukhala m'madzi tsiku lonse, kubwera kumtunda yekha usiku kuti zapamoyo. Nthawi zina kufunafuna chakudya zingawapangitse chapatali ndithu (7-8 km) kumtunda, kotero iwo mowolowa manja amalembedwa njira zawo kuti pambuyo mosavuta kupeza njira kwanu kusanache. Usiku umodzi uwu nyama bulky akhoza kuyamwa mpaka makilogalamu 100 zomera.

Akuluakulu kukhoza kuchuluka yaikulu udzu, tagwira wake ndi pakamwa pake lonse, osati mano, ngati herbivores ena ambiri. Otchedwa mtsinje kavalo pafupifupi yosalala, wopanda tsitsi ndi khungu tcheru kwambiri, pores amene exude wofiira wochuluka madzi kuti amachita ngati sunscreen ndi kusunga khungu hydrated ndi kuteteza, pamene nyama ndi pa dziko. Chifukwa cha mbali chidwi izo zinapangidwa ndi kopanda olakwika kuti mvuu thukuta magazi.

Mvuu ndi tusks lalikulu (incisors) ndi canines, amene sasiya kukula kwa moyo wawo. tusks amenewa amaonedwa wapatali kuposa njovu, chifukwa iwo musapatuke chikasu ndi zaka. "Mtsinje kavalo" ali m'kamwa linafalitsidwa kwambiri mwa aliyense nyama lapadziko panopa alipo, ndi pamene chimphona zamiyendo Inayi amatsegula pakamwa pake kwa yawn, mtunda wa pakati nsagwada kungakhale 60 masentimita!

wochezeka nyama

Ngakhale kukula kwake lalikulu ndi buku, Mvuu tofa zokwanira nyama, zomwe mosavuta kuwathawa anthu. Mvuu kungakhale grumpy ndithu zirombo, ndipo amuna awiri kungakhale nthawi yaitali kumenyana wina ndi mzake, nthawi zina kuchititsa anavulala kwambiri.

Zimawuluka ambiri imakhala nyama teni mpaka fifitini chikukhudza mwamuna wina lalikulu, angapo amuna wamng'ono ndi akazi, achinyamata ndi kukula. akazi Mimba zambiri kumatenga za 230 masiku. Kubereka zambiri amapezeka mu madzi, komanso kubereka lenileni mu miyezi mvula lolemera, koma angayambe nthawi zina pachaka. mvuu Young amagwira kwambiri amayi awo ndi zambiri nthawi yocheza basking pa misana yawo ikuluikulu.

malo

Malo achilengedwe a nyama yotereyi ufulu kwa Africa, makamaka kum'mwera kwa chipululu cha Sahara. Kale, mvuu komanso anakumana kumpoto, mu Nile Delta, ndi mafano awo ali zofala mu luso ku Iguputo. Panopa, malo mvuu malo ndi nyanja, mitsinje ndi m'madambo a East ndi Africa Central.

Onani mvuu m'madzi

Mbali chidwi ndi kukhalapo kwa mvuu yeniyeni kwachilengedwenso magalasi - Kakhungu mandala okuta maso kotetezedwa, ndipo nthawi yomweyo kuzipatsa kuona m'madzi. Pa madzi ndi, mphuno zawo atsekedwa, iwo akhoza kukoka mpweya awo kwa mphindi zisanu kapena kuposerapo. Mvuu ngakhale kugona pansi madzi, ntchito reflex kuti zimawathandiza kugwedeza mutu wake m'njira akhoza kutenga mpweya ndi kugwa, ndipo sasamala ngakhale kudzuka.

Komabe, ngakhale zimasintha zonsezi moyo mu madzi, nyama ( "mtsinje kavalo") sangathe kusambira. matupi awo ndi wandiweyani kwambiri kusambira, mvuu ikuyenda bwalo, kuyambira pansi pa mtsinje kapena kungoti kuyenda m'mphepete mwa mtsinje umo_mosangalala gallop, mopepuka kukhudza pansi pang'ono Ngati a Bakha zala.

Mvuu moyo avareji zaka 40-50, choncho pamene membala aliyense wa m'banja lawo anali atakhala zaka 61, ngakhale mu ukapolo. N'zosadabwitsa herbivore ichi chachikulu amagwiritsa ochuluka mano zoopsa yekha chitetezo ndi kulimbana ndi mtundu wawo.
