Kuleplanethi kunezinhlobo eziningi zezinto eziphilayo ezikhona. Lokhu kusho ukuthi atholakala kuphela ohlotsheni oluthile lwe-ecosystem. Azitholakali kwenye indawo ngaphandle kwendawo ethile. Olunye uhlobo lwendawo olwaziwa kakhulu emhlabeni yi isibankwa peje. Baziwa futhi ngamagama ajwayelekile wamathambo noma ama-manjuaríes futhi bayizinhlanzi ezidla amanzi angenasawoti. Lezi zilwane zingezomndeni wakwaLepisosteiformes oqukethe imikhakha emibili nezinhlobo ezi-2 ezahlukene.
Kulesi sihloko sizokutshela ngazo zonke izici, indawo yokuhlala, ukondla nokukhiqizwa kabusha kwe-alligator.
Izici eziyinhloko
Lolu hlobo lwesilwane lubukeka lunomzimba ohlangene futhi oyindilinga. Singabantu futhi kubukeka njengeshubhu. Isikhumba sabo simbozwe izikali ezimise okwedayimane ezisebenza umsebenzi oyinhloko wokuvikela. Kufana nokuthi kunjalo izikhali zakhe ezimvikela ekuhlaselweni yizilwane. Iphinde ibe nesifonyo esikhulu ngokungenakulinganiswa maqondana nawo wonke umzimba. Le mpumulo ingesinye sezici ezenza isibankwa sibe yisilwane esiyingozi.
Inokuziphatha okunobudlova futhi okuyindawo okwenza ukuthi ivikele indawo yayo kahle kakhulu. Ezinye zazo zingaba zikhulu kakhulu, zifinyelele kumamitha amathathu ubude. Imvamisa zikala cishe amakhilogremu ayi-3, yize ezinye izinhlobo zinesisindo esifinyelela ku-100 kilos. Isidlayo esinolaka kakhulu futhi ngenxa yalokhu sinomhlathi oqinile nonamandla kakhulu.
Ukuze zibambe inyamazane yazo, zinamazinyo abukhali futhi acijile asebenzela ukudwengula izisulu zazo zibe izicucu. Lezi zici ezaziwa kakhulu ngalolu hlobo lwendalo ukuthi yizinhlanzi okuthi, yize zivame ukubhukuda ngejubane, zingakhula ngesivinini esimangalisayo lapho zihlasela inyamazane yazo. Kucatshangwa ukuthi esinye sezizathu sokuthi kungani isibankwa peje singasekho ngenxa yamandla aso adlulele okuzivumelanisa nokuphila. Futhi ngabe yilezi zilwane ziyakwazi ukukhula emanzini angenamkhawulo avame ukuba yingozi, angakhululeki futhi angajabulisi ezinye izinhlobo.
Ku-pejelagarto sithola izinhlobo ezithile ezihlukile. Amanzi amaningi kakhulu futhi aziwayo eMexico yi-Atractosteus tropicus. Ingenye yezinhlobo eziyigugu kakhulu futhi edotshwa ngabantu baseMexico, ngoba izitsha ezinkulu ezingavamile zingalungiswa ngalesi sithako.
Ububanzi nendawo okuhlala kuyo i-alligator peje
Njengoba sishilo ekuqaleni kwendatshana, kuyizinhlobo eziphilayo. Lokhu kwenza ukuthi ihlale ezindaweni ezithile kuphela. Kulokhu, isibankwa se-alligator sihlala emanzini asempumalanga yeNyakatho Melika naseMelika Ephakathi: ikakhulukazi phakathi kweMontana, iQuebec eseningizimu neCosta Rica. Indawo yabo yemvelo yayijwayele ukusabalala kakhulu, yize kungenxa yabantu kanye nokuguqulwa kwemvelo ezungezile, abantu abakwazi ukuzivumelanisa nesikhathi. Kunobunye ubufakazi bemivubukulo bokuthi lezi zilwane zitholakale ezingxenyeni ezihlukene ze-Afrika, iYurophu, iNingizimu Melika kanye neSouth Asia. Noma kunjalo, okwamanje itholakala kuphela endaweni eyodwa.
Ngokuqondene nendawo yokuhlala yayo yemvelo, siyabona ukuthi imvamisa ihlala emanzini azolile kakhulu. Lawa ngamanzi lapho imisinga ihamba kancane kakhulu futhi ijwayele ukubhukuda ezingeni lomhlabathi. Imvamisa ihlala etindzaweni letinemaxhaphozi kanye nasemachibini. Ukuba yinhlanzi enokuziphatha okuhle, kuvame ukuhlala kunganyakazi ukonga amandla. Kuthathwa ngumsinga wamanje ukusuka kwenye indawo uye kwenye bese ulinda inyamazane ezowela ukuze ikwazi ukondla.
Ukuzivumelanisa nezimo okukhulu kwalesi silwane ezindaweni ezingezinhle kuvela ekubekezelelaneni okukhulu kuya emazingeni okushisa aphakeme kakhulu. Ngakho-ke, siyayibona i-alligator ezindaweni ezivulekile ezikhethekile ngokubhukuda.
Ukondla nokuzala kabusha
Ukudla kwalesi silwane kusekelwe kwezinye izinhlanzi nakwezinye izinhlanzi. Bayakwazi ukondla izilwane eziphilayo nezifile. Konke lokhu kuzoncika enanini lokudla okutholakala ku-ecosystem lapho kutholakala khona. Uma ukudla kwenziwa ekhaya, kuzophendukela ekudleni. Ungadla futhi i-squid noma imfanzi nezinsalela zazo. Obunye bobuhle obuhle be-alligator umhlathi wayo omude. Njengoba sishilo ngaphambili, le nkathi yomhlathi iyenza ibe ngumzingeli ngokuzingela okusheshayo nangokuthula. Lezi izinzuzo ezinkulu ngaphezu kwesisulu sabo.
Njengoba siyisilwane esinenkani kakhulu, sondla ngayo yonke into engangena emlonyeni wayo. Iyakwazi ukubamba ukuhamba kwezinyoni ezincane ngokusabela ngokushesha.
Ngokuqondene nokuzala kwayo, kuzoba semanzini ahlanzekile kuphela futhi kugcwele ulwelwe nokhula. Isikhathi sokuzalisa senzeka phakathi kwezinyanga ezisukela ku-Ephreli kuya kuJuni. Lapho kuqala inkathi yokuzalanisa, insikazi yiyo engakhipha amaqanda afinyelela ku-8000. La maqanda aqanduselwa kanti amaphuphu aphumela obala ngezinsuku eziyisikhombisa nje kuphela. Isikhathi sokuphila se-alligator siphakathi kweminyaka engama-25 nengama-40, yingakho sithathwa njengesilwane esiphila isikhathi eside.
Ngabe isilonda se-alligator sisengozini?
Ukuba wuhlobo lwendalo nokuba umgomo wabantu ukulungisa izitsha, kuyinto ejwayelekile ukucabanga ukuthi lesi silwane singaba sengozini yokuqothulwa. Kodwa-ke, okwamanje, isibankwa peje asikho engcupheni yokuqothulwa ngoba izinhlobo ezi-7 ezihlala njalo zivamile esifundeni ngasinye lapho zitholakala khona. Kuyinhlanzi ebaluleke kakhulu kubo bonke abadobi futhi, ngenxa yobulukhuni bayo obumangalisayo nokumelana nayo, inikeza ukudoba okuthakazelisa impela.
Kubuye kube yinhlanzi edliwayo, yize bembalwa kakhulu abantu abayidlayo. Lokhu kungenxa yokuthi iqukethe ameva amaningi futhi kwenze kube nzima ukuhlafuna nokugwinya. Amaqanda anobuthi ngakho-ke awadliwanga ngabantu. Zonke lezi zizathu yizo ezenza lesi silwane singabi sengozini yokuqothulwa.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngesibankwa nezici zaso.
