Komanso amuna ndi akazi amasiyana mtundu waubweya wawo. Mwa amuna, ili ndi mtundu wa mbewa. Ndipo akazi amavala zovala zakuda, ngati zapansi. Chovala chawo chaubweya chokha chimakhala ndi ulusi wafupikitsa, wonenepa kwambiri komanso wolimba.

Koma ukamayang'ana patali, imawoneka yokongola kwambiri. Monga zimphona zokwawa zomwe zikukwawa kuchokera pansi pa nyanja. Zomwezo sizinganenedwe za nyengo ya molting. Theka lachisanu, nyama ili pagombe.

Khungu lake limakutidwa ndi matuza, ndipo limatuluka pamalowo. Nthawi zonse m'madzi njovu Samadya chilichonse, atagona pamavuto am'mbali mwa nyanja. Popeza njirayi ndiyopweteka komanso yosasangalatsa.

Chosangalatsa chokhudza zisindikizo za njovu ndikuti nthawi yokolola, thunthu lamphongo limakula. Magazi amayenderera kwa iyo, minofu imayamba kugwirana, ndipo kuyambira pakatikati pa masentimita makumi atatu, theka la mita kapena kupitilira apo, china chake chimayamba.

Mutu wa nyama izi ndi waung'ono kukula, ukuyenda bwino mthupi. Ili ndi maso ang'onoang'ono, amdima a azitona. Khungu lomwe lili pakhosi la zisindikizo za njovu ndilolimba kwambiri komanso lolimba. Amateteza nyamayo kuti isalumidwe pakamwa mating.

Thupi lawo lalikulu limathera mchira waukulu, wokhala ndi mphanda ngati nsomba. Ndipo kutsogolo, m'malo mwa miyendo, pali zipsepse ziwiri zokhala ndi zikhadabo zazikulu.

Njovu zimasindikiza moyo ndi malo okhala

Kotero Kodi zisindikizo za njovu zimakhala kuti? Ma pinniped akumpoto, okhala kosatha ku California ndi madzi aku Mexico. Ngakhale zaka zana zapitazo, iwo anali pafupi kutha.

Chiwerengero cha anthu awo sichidapitilira zana nyama. Iwo anaphedwa mwankhanza powabaya ndi mikondo chifukwa cha mafuta amtengo wapatali a nyama. Kwa njovu, idakhala ngati gawo losanjikiza la masentimita khumi ndi asanu kuchokera kumadzi achisanu.

Kumalo komwe adawonongedwa ndikusungunuka mafuta awa. Chiwerengero chake chinafika mamilioni a kilogalamu, ndi momwe anthu masauzande ambiri amafunikira kuwonongedwa. Mpaka pano, kukumbukira nthawi zowawa, zombo zokutidwa ndi udzu wam'madzi, ndowe za mbalame ndi dzimbiri zimwazikana m'mbali mwa magombe.

Ogwira ntchito adamenya nkhondo molimbika kuti apulumutse anthu awo. Zomwezo sizinganenedwe za ng'ombe zam'nyanja, zomwe zidasowa chifukwa cha kupha nyama. Ndipo mkati mwa makumi asanu, zaka zana zapitazo, adabereka mpaka anthu zikwi khumi ndi zisanu.

Nyama yakumwera inavutikanso chimodzimodzi, amayenera kuthawa, kukhazikika kuzilumba zomwe zimapezeka movutikira ku South Georgia, Marion. Momwemonso, pali malo angapo ogulitsira nyama ku Macquarie ndi Heard Island.

Chiwerengero cha anthu mu rookery imodzi ndi makumi masauzande. Zilumba za Argentina zakhala malo otetezedwa, ndipo kwazaka makumi asanu, kusaka nyama konse kwakhala koletsedwa.

Ndipo kale, mu zaka makumi asanu ndi limodzi, akatswiri a sayansi ya zamoyo anayamba kuphunzira zisindikizo za njovu. Ngakhale amakhala ndi magawo akulu, nyama izi zimasangalala m'madzi. Amasambira mokongola, kufika liwiro la makilomita makumi awiri paola.

Chifukwa chake, atalimbana ndi zochitika zake pagombe, njovu imachedwa kutopa kwambiri. Ndipo chinthu choyamba chomwe chimabwera m'maganizo mwake ndi kugona pang'ono. Kuphatikiza apo, iwo amagona tulo tofa nato, ndipo akuthodola ndimphamvu kwambiri kwakuti asayansi atha kubwereza mobwerezabwereza, osawopa moyo wawo, kuwerengera kupuma kwawo, kumvera kugunda kwawo ndikukhala ndi mtima wamtima.

Zonsezi zimayamba ndi njovu zomwe zimatsetsereka kugombe. Mkaziyo wakhala ndi pakati kuyambira chaka chatha. Zowonadi, panthawiyi amawerengera miyezi khumi ndi chimodzi. Njovu zamphongo sizigwirizana ndi njira yolerera ana.

Atapeza malo abata, osawonekera, mayiyo amabereka mwana mmodzi yekha. Amabadwa wamtali mita, ndipo amalemera mpaka makilogalamu makumi anayi. Kwa mwezi wathunthu, mayi wanjovu amadyetsa khanda ndi mkaka wake wokha.

Ndi m'gulu la oimira anthuwa, omwe ali ndi kalori yayitali kwambiri. Mafuta ake ndi makumi asanu peresenti. Mukamadyetsa, mwanayo amalemera bwino. Pambuyo pake, mayiyo amasiya mwana wake kwamuyaya.

Anawo anali ndi mafuta okwanira ochepa kuti athe kukhala ndi moyo m'mwezi wotsatira wodziyimira payokha. Atakwanitsa miyezi itatu, ana amasiya malo ogulitsira ndikupita m'madzi otseguka.

Mkazi atangochoka kwa mwana wake, nthawi yolimbana popanda malamulo imayambira. Njovu zazikulu kwambiri komanso zakale kwambiri zimamenyera moyo ndi imfa, kuti akhale ndi ufulu wokhala sultan wa azimayi awo.

Ndipo wovulalayo, ndi onse ovulala, amapita kumapeto kwa rookery. Amadzipezabe wokwatirana naye, wopanda ulamuliro wa mwamuna wamwamuna. Ndizomvetsa chisoni, koma pankhondo zoterezi, nthawi zambiri ana ang'onoang'ono amavutika ndikufa, samadziwika pankhondo, ndipo amaponderezedwa ndi akulu.

Atasonkhanitsa akazi ake, mtsogoleriyo amasankha kumulakalaka yekha, ndikuyika choyipitsa chakumbuyo kwake kumbuyo. Chifukwa chake akuwonetsa kupambana kuposa iye. Ndipo ngati mayiyo sakufuna kukumana, mwamunayo samasamala za zoterezi. Amakwera matani ake onse kumbuyo kwake. Apa, ma resistances alibe ntchito.

Kukula msinkhu kumayamba, m'badwo wachinyamata, pofika zaka zinayi mwa amuna. Amayi, kuyambira azaka ziwiri, amakhala okonzeka kukwatira. Kwa zaka khumi, zisindikizo zachikazi za njovu zatha kubereka ana. Ndiye amakalamba. Zisindikizo za Njovu zimafa ali ndi zaka khumi ndi zisanu, makumi awiri.

Ngakhale atsekwe zazikulu kwambiri, zisindikizo za njovu zimakhalanso nyama ya anangumi omwe amapha. Kambuku kameneka kamatsatira ana aang'ono. Koma adani owopsa kwambiri, kwazaka zambiri, ngakhale zitamveka zowopsa bwanji, ndife anthu.
