I-Nile monitor enamandla ikhumbuza icilikishe elaphela ixesha elide. Ngepateni yayo, yenye yezona zinto zintle, kodwa kunye nabameli abanobundlongondlongo bemilisi esweni.
iimpawu
Ijongeka njani iNile monitor?
Iimonitha ze-Nile zezosapho lwecilikishe kwaye ke zizilwanyana ezirhubuluzayo. Ookhokho babo babephila emhlabeni malunga neminyaka eyi-180 yezigidi eyadlulayo. Umzimba wazo ugqunywe ngamaxolo amancinci, aluhlaza-mnyama ngombala kwaye anepateni yamabala atyheli kunye nemigca ethe tye. Isisu sityheli kunye namachokoza amnyama. Abaselula baneempawu eziqaqambileyo ezityheli kwimvelaphi emnyama. Nangona kunjalo, amacikilishe oMnayile aphelelwa ngumbala njengoko ekhula.
Iimonitha zeNayile ngamacikilishe amakhulu kakhulu: Umzimba wawo umalunga neesentimitha ezingama-60 ukuya kuma-80 ubude, nomsila wawo onamandla unokufikelela kwiimitha ezimbini xa uwonke. Intloko yazo incinci kwaye incinci kunomzimba, iimpumlo zimalunga nesiqingatha phakathi kwencam yempumlo namehlo, kwaye intamo inde.
Iimonitha zeNayile zinemilenze emine emifutshane, eyomeleleyo eneenzipho ezibukhali eziphelweni. Izilwanyana ezirhubuluzayo ezininzi ziye zathatyathelw’ indawo ngamatsha ubomi bazo bonke; Imonitha yeNayile yahlukile. Amazinyo akhe akasoloko ekhula, kodwa atshintsha ngexesha lobomi bakhe. Kwizilwanyana ezincinci, amazinyo abhityile kwaye atsolo. Ziba banzi kwaye zibhinqe ngokukhula kweminyaka kwaye ziguquke zibe yimolars yokwenyani. Amanye amacikilishe amadala anezikhewu emazinyweni ngenxa yokuba amazinyo amadala awileyo awasekho.
Bahlala phi abahloli beNayile?
Abahloli beNayile bahlala kwi-Afrika ekwi-sub-Sahara ukusuka eYiputa ukuya eMzantsi Afrika. Amanye amacikilishe ahlala kwiindawo ezitshisayo nezamazama eAfrika, eAsia, eOstreliya naseOceania. Iimonitha zeNayile ziphakathi kweemboniselo ezifana nendawo yokuhlala emanzi. Ngoko ke zidla ngokufunyanwa kufuphi nemilambo okanye amachibi kumahlathi alula kunye nama-savanna okanye ngokuthe ngqo kwiindonga zamanzi.
Zeziphi iintlobo zokuhlola umNayile ezikhoyo?
Zimbini ii-subspecies ze-Nile monitor: iVaranus niloticus niloticus ayiphawulwanga ngokucacileyo ngomthubi, iVaranus niloticus ornatus inombala onamandla ngakumbi. Ifumaneka kumazantsi eAfrika. Namhlanje kukho iindidi ezingama-47 ezahlukeneyo zamacikilishe ukusuka eAfrika ukuya kuMzantsi-mpuma weAsia ukuya eOstreliya. Phakathi kweyona dragon inkulu kwi-Southeast Asian Komodo dragon, ekuthiwa ifikelela kwiimitha ezintathu ubude kunye ne-150 yeekhilogram ubunzima. Ezinye iintlobo zezilwanyana ezaziwayo yi-watermonitor, i-steppe monitor okanye i-emerald monitor ehlala phantse kuphela emithini.
Ingaba iimonitha zeNayile ziba neminyaka emingaphi?
Iimonitha zeNayile zinokuphila ukuya kutsho kwiminyaka eli-15.
Ziphathe
Ziphila njani iimonitha zeNayile?
Iimonitha zeNayile zafumana igama kuNayile, umlambo omkhulu waseAfrika kumantla-mpuma eAfrika. Izilwanyana zidlamkile emini – kodwa kuphela xa zithe zafudumala elangeni zithi zivuke ngokwenene. Iimonitha zeNayile zihlala kufutshane nemingxuma yamanzi. Yiyo loo nto ngamanye amaxesha zikwabizwa ngokuba zii-iguana zamanzi. Kwiindonga zamanzi, benza imingxuma ubude beemitha ezininzi.
Iimonitha zeNayile zihlala emhlabeni, zinokubaleka ngokukhawuleza. Ngamanye amaxesha zikwakhwela emithini kwaye ngaphezulu koko, zilungile kwaye zintle kwaye ziyakwazi ukuhlala ngaphantsi kwamanzi ukuya kwiyure ngaphandle kokuphefumla. Xa zisongelwa, zibalekela emachibini nasemilanjeni. Iimonitha zeNayile zihlala zodwa, kodwa kwiindawo ezilungileyo ezinokutya okuninzi, iindidi ezahlukeneyo zokuhlola ngamanye amaxesha zihlala kunye.
Iimonitha zeNayile zinembonakalo enomtsalane yokuziphatha: Xa zisongelwa, zinyusa imizimba yazo ukuze zibonakale zikhulu. Zikwatswina imilomo yazo ivulekile – yonke le nto ibonakala isoyikiso kwisilwanyana esikhulu kangaka. Esona sixhobo sazo, nangona kunjalo, ngumsila wabo: banokuwusebenzisa ukubetha ngamandla njengesabhokhwe. Kwaye ukulunywa kwazo kunokuba buhlungu kakhulu, kubuhlungu ngakumbi kunokwamanye amacilikishe.
Ngokubanzi, xa udibana nabahloli beNayile, intlonipho iyabizwa ngokuba: Bajongwa njengawona malungu asebenzayo nanobundlongondlongo osapho lwabo.
Abahlobo kunye neentshaba ze-Nile monitors
Ngaphezu kwako konke, abantu basisisongelo sokujonga amacikilishe. Umzekelo, ulusu lwe-monitor yeNayile lucutshungulwa lube yisikhumba; ngoko ke uninzi lwezi zilwanyana luyazingelwa. Njengeentshaba zendalo, jonga amacikilishe kufuneka woyike amarhamncwa amakhulu, iintaka ezidla inyama okanye iingwenya.
Ingaba iimonitha zeNayile zivelisa njani kwakhona?
Njengazo zonke izilwanyana ezirhubuluzayo, jonga amacilikishe abeka amaqanda. Iimazi zokuhlola umNayile zibeka amaqanda ali-10 ukuya kuma-60 kwiziduli zeentubi. Oku kudla ngokwenzeka ngexesha lemvula, xa iindonga zemingxuma zithambile kwaye iimazi zinokuyivula ngokulula ngamazipho azo abukhali. Umngxuma ezibeka kuwo amaqanda uphinda uvalwe ziintubi. Amaqanda alala eshushu kwaye akhuselekile kwinduli yentubi kuba akhula kuphela xa ubushushu bungama 27 ukuya ku 31°C.
Emva kweenyanga ezine ukuya kwezilishumi, intshontsho liyaqanduselwa lize ligrumbe ngaphandle kwenduli yeentubi. Ipateni kunye nemibala yazo iqinisekisa ukuba azibonakali. Ekuqaleni, zihlala zifihlwe emithini nasematyholweni. Xa zimalunga neesentimitha ezingama-50 ubude, ziyatshintsha zihlale phantsi zize zitye khona.
Ngaba abahloli beNayile banxibelelana njani?
Iimonitha zeNayile zingenza umsondlo kwaye zifuze.
