Ng'ona ndi anyani agalu ndiomwe amakhala nzika zakale kwambiri padziko lapansi, ndipo, malinga ndi asayansi ambiri, zaka zawo zimapitilira zaka za ma dinosaurs. Poyankhula kwatsiku ndi tsiku, mayina a nyama ziwirizi amasokonezeka nthawi zambiri, chifukwa cha mawonekedwe akunja akunja. Komabe, nyama zankhumba ndi ng'ona zomwe zili mu dongosolo la Crocodylia zimakhala ndi zosiyana zambiri, zomwe nthawi zina zimakhala zovuta kuti munthu wamba azidziwe okha.
Kuyerekeza ndi mawonekedwe
Kusiyanitsa kwakukulu pakati pa alligator ndi oimira ena omwe ali motsatira dongosolo la ng'ona ndi kutsekeka kokulirapo komanso kupindika kwamaso. Mtundu wa ng'ona ndi alligator umasiyana pang'ono kutengera mitundu ndi malo okhala. Poyerekeza ndi ng'ona yeniyeni, makamaka woimira mtundu wa Crocodylus, nsagwada zitatsekedwa, alligator imangowona mano apamwamba.
Anthu ena ali ndi mano opunduka, omwe amatha kubweretsa zovuta zina podziwitsa. Ma alligator akulu amadziwika ndi maso omwe ali ndi kuwala kofiira. Anthu ang'onoang'ono amtundu uwu wa zokwawa amadziwika ndi kuwala kobiriwira kokwanira, komwe kumapangitsa kuti azindikire alligator ngakhale mumdima.
Ng'ona zili ndi chakuthwa chakuthwa kwambiri chomwe chimatchedwa V, ndipo kusiyana kwake ndiko kukhalapo kwa kuluma kwapadera kwambiri potseka nsagwada. Pakamwa pa ng'ona patatsekedwa, mano a nsagwada zonse zimawoneka bwino, koma mayini a nsagwada zakumunsi zimawonekera kwambiri. Pamwamba pa thupi la ng'ona pamadzaza ndi mitundu yaying'ono yakuda, yomwe imakhala ngati "mota sensors".
Mothandizidwa ndi dongosolo lapaderali, yolumikizana imatha kugwira mosavuta ngakhale kuyenda pang'ono kwa nyama yake. Ziwalo zamagetsi za Alligator zimangopezeka mkamwa... Mwazina, kutalika kwakatundu ka alligator nthawi zambiri kumakhala kofupikirapo kuposa kukula kwa thupi la mamembala ena a ng'ona.
Mwina zidzakhala zosangalatsa: ng'ona zazikulu kwambiri
Kuyerekeza ndi malo okhala
Habitat ndichinthu chofunikira kwambiri chomwe chimalola kusiyanitsa kolondola kwa mitundu yonse ya zamoyo. Ma Alligator ali ponseponse m'madzi amadzi oyera omwe ali ku China ndi North America.
Ndizosangalatsa!Oimira ambiri a ng'ona amatha kukhala m'madzi abwino komanso m'madzi amchere amchere.
Izi zimakhudzana ndi kupezeka kwa tiziwalo tating'onoting'ono m'kamwa mwa ng'ona, zomwe zimayambitsa kuthetseratu mchere wambiri. Ma Alligator amakumba maenje kuti apange timadzi ting'onoting'ono tomwe pambuyo pake timakhala malo okhala nsomba komanso malo okumbiramo nyama zina kapena mbalame.
Ng'ona ndi moyo wa nyama yakutchire
Amuna akulu a alligator amakonda kukhala moyo wokhawokha, komanso kutsatira madera awo okhazikika. Anthu ochepera amadziwika ndi mayanjano m'magulu akulu... Amuna ndi akazi achikulire nthawi zonse amakhala otanganidwa poteteza gawo lawo. Ma alligator achichepere amalekerera achibale ofanana.
Ndizosangalatsa!Ma Alligator, okhala ndi kulemera kwakukulu komanso njira yochepetsetsa yamagetsi, amatha kukhala ndi liwiro labwino pamtunda woyambira posambira.
Ng'ona ikakhala m'madzi imayenda mothandizidwa ndi gawo la mchira. Monga ma alligator, pamtunda zokwawa izi ndizopepuka komanso zosakhazikika, koma, ngati kuli kotheka, zimatha kusunthira kutali ndi dziwe. Pochita kuyenda mofulumira, zokwawa zochokera pagulu la ng'ona nthawi zonse zimayika miyendo yayikulu pansi pa thupi.
Phokoso lomwe ng'ona ndi akaligwere amapanga ndi zinazake pakati pa kubangula ndi kukuwa. Khalidwe la zokwawa zimakhala zazikulu kwambiri panthawi yobereketsa.
Mamembala a ng'ona amakula m'miyoyo yawo yonse. Izi zimachitika chifukwa chakupezeka kwamatenda omwe amakula nthawi zonse omwe ali m'mafupa. Mitundu yaying'ono imakula msinkhu wazaka zinayi. Mitundu ikuluikulu imayamba kukhwima pafupifupi zaka khumi zakubadwa.
Mosiyana ndi ng'ona, kukhwima mwa mtundu wina wa alligator kumadalira kwambiri kukula kwake, osati pazaka zake. Ma alligator a Mississippi amakhala okhwima pogonana thupi litatha kutalika masentimita 180. Zigawenga zazing'ono zaku China zimayamba kukhathamira thupi likafika mita imodzi kutalika.
Kutengera malo okhala ndi zamoyo, nthawi yayitali ya moyo imatha kukhala pakati pa zaka 70-100. Monga lamulo, achikulire kwathunthu, anthu okhwima mwakugonana amitundu yayikulu kwambiri ya ng'ona ndi anyani agalu sanatchule adani m'malo awo achilengedwe.
Komabe, nyama zambiri, kuphatikizapo kuyang'anira abuluzi, akamba, nyama zodya nyama ndi mitundu ina ya mbalame, sizimadya mazira okha omwe amaswa ndi ng'ona, komanso zokwawa zazing'ono kwambiri zamtunduwu zomwe zangobadwa kumene.
Kodi pali kusiyana kotani pakati pa chakudya cha ng'ona ndi alligator
Zokwawa za mitundu imeneyi zimakhala nthawi yayitali kwambiri m'madzi, ndipo zimapita kugombe lakuya m'mawa kwambiri kapena pafupi ndi madzulo. Oimira gulu la ng'ona amasaka nyama zawo usiku. Zakudyazi zimayimiriridwa ndi nsomba, koma nyama iliyonse yomwe nyamayi imatha kupirira itha kudyedwa. Tinyama tating'onoting'ono tambirimbiri timagwiritsidwa ntchito ngati chakudya ndi ana, kuphatikiza tizilombo, nkhanu, nkhono ndi nyongolotsi.
Okalamba amasaka nsomba, amphibiya, zokwawa komanso mbalame zam'madzi. Zilombo zazikulu komanso ng'ona, nthawi zambiri zimatha kuthana ndi nyama zazikulu kwambiri. Mitundu yambiri ya ng'ona imadziwika ndi kudya anthu, komwe kumadya nyama zazing'ono zamtunduwu ndi anthu akulu kwambiri kuchokera pagulu la ng'ona. Nthawi zambiri, ng'ona ndi anyani amadya nyama yakufa komanso yowonongeka.
Mawu omaliza ndi omaliza
Ngakhale kufanana kotchulidwa kwakunja, nkosatheka kusokoneza ng'ona ndi alligator mukayang'anitsitsa:
- ma alligator nthawi zambiri amakhala ocheperako kuposa ng'ona;
- Ng'ona zili ndi mphuno yopapatiza komanso yayitali, pomwe ma alligator ali ndi mawonekedwe osalala komanso osamveka;
- ng'ona ndizofala kwambiri ndipo pakadali pano pali mitundu pafupifupi khumi ndi itatu ya chokwawa ichi, ndipo ma alligator amaimiridwa ndi mitundu iwiri yokha;
- ng'ona zili ponseponse ku Africa, Asia, America ndi Australia, ndipo nyama zanyama zonse zimapezeka ku China ndi America kokha;
- Mbali ina ya ng'ona ndizomwe zimasinthasintha madzi amchere, pomwe malo okhala anyaniwa amangoyimiriridwa ndi malo osungira madzi atsopano;
- ng'ona zimadziwika ndi kupezeka kwa zopangitsa zapadera zomwe zimapangidwa kuti zichotse mchere wambiri mthupi, ndipo zotumphukira sizimatha.
Chifukwa chake, palibe kusiyana kochuluka kwambiri, koma yonse imadziwika kwambiri ndipo, ndikuwona, imakulolani kusiyanitsa molondola nthumwi ya ng'ona.
