Izingwenya nama-alligator cishe yizakhamizi zakudala kakhulu zeplanethi yethu, futhi, ngokusho kososayensi abaningi, iminyaka yazo idlula ngisho nesikhathi sokuphila sama-dinosaurs. Enkulumweni yansuku zonke, amagama alezi zilwane ezimbili avame ukudideka, ngenxa yokufana kwangaphandle. Yize kunjalo, izingwenya nezingwenya zohlelo lwe-Crocodylia zinokuhluka okuningi okuphawulekayo, kwesinye isikhathi okunzima kumuntu ojwayelekile ukuzitholela kona.
Ukuqhathanisa ngokubukeka
Umehluko omkhulu phakathi kwe-alligator nabanye abameleli abangabokuhleleka kwezingwenya yisibopho esibanzi nokuma kwamehlo emuva. Umbala wengwenya ne-alligator wehluka kancane kuye ngohlobo lwendawo nendawo yokuhlala. Uma kuqhathaniswa nengwenya yangempela, ikakhulukazi omele uhlobo lohlobo lweCrocodylus, umhlathi uvaliwe, ingwenya ibona amazinyo aphezulu kuphela.
Abanye abantu banamazinyo akhubazekile, okungadala ubunzima obuthile enkambisweni yokuhlonza. Ama-alligator amakhulu abonakala ngamehlo anokukhanya okubomvu. Abantu abancane balolu hlobo lwezilwane ezihuquzelayo bahlukaniswa ngokukhanya okuluhlaza okwanele ngokwanele, okwenza kube lula ukuthola i-alligator ngisho nasebumnyameni.
Izingwenya zinomlomo obukhali futhi obizwa ngo-V, futhi umehluko wesici ukuba khona kokuluma okuyisipesheli lapho kuvalwa imihlathi. Lapho umlomo uvaliwe, amazinyo engwenya abonakala ngokusobala emihlathini yomibili, kepha imisipha yomhlathi ongezansi ibonakala kakhulu. Ubuso bomzimba wengwenya bumbozwe ngamabala amancane wombala omnyama, asebenza njengohlobo lwe "motor sensors".
Ngosizo lwesakhiwo esikhethekile, esihlanganisayo sikwazi ukubamba kalula ngisho nokuhamba okuncane kokudla kwaso. Izitho zezinzwa ze-Alligator zitholakala kumlomo kuphela... Phakathi kwezinye izinto, ubude obumaphakathi bomzimba we-alligator imvamisa bufushane ngokuphawulekayo kunosayizi womzimba wamanye amalungu ohlelo lwezingwenya.
Mhlawumbe kuzoheha: izingwenya ezinkulu kakhulu
Ukuqhathanisa ngendawo yokuhlala
Indawo yokuhlala yinto ebaluleke kakhulu ekuvumela ukwehlukaniswa okulungile kwazo zonke izinhlobo zezinto eziphilayo. Ama-alligator asakazeke kakhulu emanzini angenasawoti atholakala eChina naseNyakatho Melika.
Kuyathakazelisa!Abamele abaningi bohlobo lwengwenya abakwazi ukuhlala hhayi emanzini amasha kuphela, kodwa nasezinqolobaneni ezinamanzi anosawoti.
Lesi sici sihlotshaniswa nokuba khona kwezindlala ezikhethekile emlonyeni wengwenya, ezibhekele ukuqedwa kasawoti okweqile ngokushesha. Ama-alligator emba imigodi ukudala imizimba emincane yamanzi kamuva eba yindawo yokuhlala enkulu yezinhlanzi nomgodi wokunisela ezinye izilwane noma izinyoni.
Indlela yokuphila yengwenya ne-alligator
Abesilisa abakhulu be-alligator bakhetha ukuphila impilo yabo bodwa, futhi babambelele ngokuqinile endaweni yabo eqinile. Abantu abancane babonakala ngokuhlangana ngamaqembu amakhulu kakhulu... Abesilisa nabesifazane abadala bahlala bekhuthele kakhulu ekuvikeleni indawo yabo. Ama-alligator amancane ayabekezelela izihlobo ezilinganayo.
Kuyathakazelisa!Ama-alligator, anesisindo esikhulu ngokwanele nezinqubo ezihamba kancane zomzimba, ayakwazi ukwenza isivinini esikahle ngaphezu kwamabanga amafushane okubhukuda.
Izingwenya, uma zisemanzini, zihamba ngosizo lwesigaba somsila. Njengama-alligator, emhlabathini, lezi zilwane ezihuquzelayo zihamba kancane futhi ziyindida, kepha, uma kunesidingo, ziyakwazi ukusuka kakhulu echibini. Ngenqubo yokuhamba ngokushesha, izilwane ezihuquzelayo ezivela eqenjini lezingwenya zihlala zifaka izitho ezibanzi ngaphansi komzimba.
Imisindo eyenziwa izingwenya nezingwenya ziyinto ephakathi kokubhonga nokukhonkotha. Ukuziphatha kwezilwane ezihuquzelayo kuba nomsindo ikakhulukazi ngesikhathi sokuzalisa okusebenzayo.
Amalungu eqembu lezingwenya akhula ezimpilweni zabo zonke. Lesi sici singenxa yobukhona bezindawo ezikhulayo ezihlale zikhona ezithweni zethambo. Izinhlobo ezincane zifinyelela ekuvuthweni ngokocansi zineminyaka emine. Izinhlobo ezinkulu zivuthwa ngokocansi cishe ngonyaka weshumi wokuphila.
Ngokungafani nezingwenya, ukuvuthwa ngokocansi kwanoma yiluphi uhlobo lwe-alligator kuncike kakhulu kubukhulu bomuntu, hhayi kubudala bayo. Ama-allissator aseMississippi ayavuthwa ngokocansi ngemuva kokuba ubude bomzimba bungaphezu kwamasentimitha ayi-180. Ama-alligator amancane aseChina aqala ukukhwelana ngemuva kokuthi umzimba usufinyelele imitha elilodwa ubude.
Ngokuya ngobuningi bendawo yokuhlala nezinhlobo zezinto eziphilayo, ubude besikhathi sokuphila bungahluka phakathi kweminyaka engama-70-100. Njengomthetho, abantu abadala ngokuphelele, abantu abavuthiwe ocansini bohlobo olukhulu kakhulu lwezingwenya nama-alligator abanazo izitha endaweni yabo yemvelo.
Kodwa-ke, izilwane eziningi, kufaka phakathi ukuqapha izibankwa, izimfudu, izilwane ezincelisayo nezinye izinhlobo zezinyoni, azidli nje amaqanda abekwe izingwenya nezingwenya, kodwa futhi nezilwanyana ezihuquzelayo ezincane kakhulu zalo myalelo osanda kuzalwa.
Uyini umehluko phakathi kokondla kwengwenya kanye ne-alligator
Izilwane ezinwabuzelayo zalezi zinhlobo zichitha isikhathi esiningi esimweni sasemanzini, futhi ziya ogwini olungashoni ekuseni kakhulu noma eduze nokuhwalala. Abamele iqembu lezingwenya bazingela inyamazane yabo ebusuku. Ukudla kumelwe kakhulu yizinhlanzi, kepha noma iyiphi inyamazane isilwane esikwaziyo ukubhekana nayo ingadliwa. Izinhlobonhlobo zezinambuzane ezingenamqolo zisetshenziswa njengokudla yizinsizwa, kufaka phakathi izinambuzane, ama-crustaceans, ama-molluscs nezibungu.
Abantu abadala bazingela izinhlanzi, izilwane eziphila emanzini nasemanzini, izilwane ezinwabuzelayo nezinyoni zamanzi. Ama-alligator amakhulu nezingwenya, njengomthetho, angakwazi ukubhekana kalula nezilwane ezincelisayo ezinkulu. Izinhlobo eziningi zezingwenya zibonakala ngokudla abantu, okubandakanya ukushwabadela abameli abancane bohlobo lwabantu abakhulu kunabo bonke kusukela kuhlelo lwezingwenya. Imvamisa, zombili izingwenya nama-alligator zidla inyama yezidumbu kanye nokubola okungajwayelekile.
Iziphetho nesiphetho
Ngaphandle kokufana kwangaphandle okucacisiwe, cishe akunakwenzeka ukudida ingwenya ne-alligator lapho uhlolisiswa:
- ama-alligator ngokuvamile mancane kunezingwenya;
- izingwenya zinempumulo emincane futhi ende, kuyilapho ama-alligator enesimo esicabalele futhi esibuthuntu;
- izingwenya zivame kakhulu futhi njengamanje kunezinhlobo ezingaba yishumi nantathu zalesi silwane esihuquzelayo, kanti ama-alligator amelwe yizinhlobo ezimbili kuphela;
- izingwenya zisabalele e-Afrika, e-Asia, eMelika nase-Australia, kanti izingwenya zitholakala kuphela eChina naseMelika;
- isici sezingwenya ukujwayela kwabo emanzini anosawoti, kuyilapho indawo yokuhlala ama-alligator imelwe kuphela ngamachibi wamanzi amasha;
- izingwenya zibonakala ngokuba khona kwezindlala ezikhethekile ezenzelwe ukukhipha usawoti omningi emzimbeni, kanti ama-alligator ancishwa ngokuphelele leli khono.
Ngakho-ke, akukho mehluko omningi kakhulu, kepha konke kushiwo kakhulu futhi, ngokubona okuthile, kukuvumela ukuthi uhlukanise ngokunembile ngokuphelele ummeleli wohlelo lwezingwenya.
