Xa sithetha ngeenyoka, uloyiko lwezi zirhubuluzi ngenxa yobuthi bazo luhlala lufika engqondweni. Esinye sezona zilwanyana zomeleleyo ezifumaneka kwindawo yaselwandle yi Enhydrin schistosa. Imalunga ne- eyona nyoka inetyhefu emhlabeni. Nangona inokuthelekiswa nezinye iintlobo zeenyoka zomhlaba ezinobuhlungu, ukuba siyayithelekisa njengereferensi yethamo elibulalayo eliphakathi, le nyoka yeyona ibulalayo emhlabeni.
Kweli nqaku siza kukuxelela ngazo zonke iimpawu, ukondla, ukuzala kunye nendawo yokuhlala yeyona nyoka inetyhefu emhlabeni.
Iimpawu eziphambili
Olu hlobo lwenyoka lunobuhlungu obuneyona dose ibulalayo ehlabathini. I-LD50 linani leemiligram ezithatha ngekhilogram ukuthumela isiqingatha seqela lezilwanyana zovavanyo. Ngombulelo kule dosi unokumisela ukuba yeyiphi eyona nyoka inetyhefu emhlabeni. Yaziwa ngegama eliqhelekileyo lenyoka yaselwandle enomlomo kwaye ifumana eli gama ngenxa yehuku enalo emlonyeni wayo njengokubonakala komlomo wayo. Ibekwe ngaphambili kumhlathi ongasentla.
Iyafana nezinye iinyoka zaselwandle, nangona iqhelene kakhulu nobomi bangaphantsi kwamanzi. Umsila wayo uthe tyaba ukumila kwephiko ukuze ukwazi ukudada. Sisilwanyana esinempumlo efana neevalvu ezikwazi ukuvala kwaye zilumkise xa inyoka iphantsi kwamanzi. Azinawo amaxolo akhulayo esiswini, njengoko uninzi lweenyoka zizisebenzisa xa zihamba emhlabeni.
Enye yeempawu ukuba Eyona nyoka inetyhefu emhlabeni kukuba ifikelela malunga neesentimitha ezili-140 ubude.. Oko kukuthi, le nyoka, ngaphezu kokuba yeyona tyhefu emhlabeni, inkulu kakhulu ngobukhulu. Ityala layo lomelele kakhulu kwaye lisicaba ngokuthe nkqo kwaye linentloko encinci kunye nomzimba wonke.
Umbala wolusu lwabo uyatshintsha ngokweminyaka yabo okwangoku. Abantu abadala badla ngokuba luhlaza lomnquma okanye buluhlaza bungwevu ngaphezulu kwaye bumhlophe ngezantsi. Kweli nqanaba lobomi banamanye amabhanti anqamlezayo amnyama adibanisayo kwindawo ekufutshane nomsila. Iminqamlezo yayo ibanzi kumzimba ongezantsi kwaye icuthe kwiindawo ezahlukeneyo kufutshane namacala. Eyona nto iqhelekileyo kukuba la mabhendi anqamlezileyo ayanyamalala xa sele ekhulile.
Izoyikiso zeyona nyoka inobuhlungu ehlabathini
Nangona iyeyona nyoka inetyhefu emhlabeni, akukho lwazi malunga nemeko yolondolozo lwendalo. Njengoko imeko yolondolozo yolu hlobo ingaziwa kakuhle, Akwaziwa ngezinye iinyoka zaselwandle, kuba izifundo zintsonkothile ngakumbi njengoko luhlobo oluphantsi kwamanzi.. Uninzi lwezi nyoka zixhatshazwa ngabantu ukwenza izikhumba, ukusetyenziswa kwamalungu kunye nenyama. Nangona kunjalo, ubukhulu besoyikiso kwinyoka yaselwandle ehlawuliweyo ayaziwa ngokupheleleyo, kuba asilazi inani labantu abakhoyo phakathi kwabantu.
Usoyikiso olubi oluvezwa ziziganeko ezahlukeneyo ezinxulumene nokuloba kunye nongcoliseko lwaselwandle nalo alunakulinganiswa. Ezinye izigrogriso ezithe chatha kwi-ikhosistim yolwandle ngenxa yokuloba ngokugqithisileyo nazo ziye zapheliswa. Ungcoliseko kunye nokutshintsha kwemozulu yimveliso yezoyikiso kolu didi. Kwaye kukuba kukho izinto ezahlukeneyo ezinokuthi zichaphazele uhlobo kunye nemeko yolondolozo.
Umntu akanakuhlala kufutshane nale nyoka njengoko inokwenzakala lula. Naxa iphathwa ngononophelo, olu hlobo lunokuba nzima kakhulu ukulugcina luvalelwe.
Ulondolozo
Nangona imeko yolondolozo yolu hlobo ingaziwa kakuhle, ngenxa yokhuseleko lwazo, abanye oorhulumente baye baqulunqa imimiselo ethintela kwaye ihlawulise nabani na owenza imisebenzi yokuloba ngolu hlobo. Ilayisensi ekhethekileyo iyafuneka ukuze ukwazi ukubamba iinyoka zaselwandle. Nangona le mithetho isebenza kakuhle kwiindawo ezikufutshane nomhlaba, kukho iindawo zokuloba iinyoka zolwandle kuLwandlekazi lwaseIndiya nolwePasifiki ezingalawulekiyo njengoko zifumaneka kumanzi aphesheya.
Kuzo zonke ezi ndawo kukho ukunqongophala kwemithetho esemthethweni kwaye iimpembelelo zayo azaziwa, kuba inani elipheleleyo labemi lingaziwa. Ngaphandle kwento yokuba ezinye iintlobo zidweliswe phantsi kweNkomfa yeHlabathi yoRhwebo lweZilwanyana eziseMngciphekweni (CITES), kusekuninzi ekusafuneka kwaziwe malunga nebhayoloji kunye nobuninzi benyoka yolwandle ezinikele kwizoyikiso zayo.
Ukuzingela eyona nyoka inobuhlungu ehlabathini
Olunye lweempawu ezenza le nyoka ikwazi ukuzingela kumanzi abonakalayo aphantsi kukubamba kwayo. Oku kubamba kwenza inyoka iginye ixhoba layo, iqala ngentloko, ize ikhuphe ubuthi bayo obunamandla. Kufuneka kuqatshelwe ukuba uninzi lwenyoka olu lwandle alufane lulume. Ngaphandle kokuluma ngokupheleleyo, azizitofi ngetyhefu eninzi, ngoko ukusebenza kwazo kuyancipha. Nangona kunjalo, lolona hlobo lundlongondlongo lukhoyo. Nge-1.5 milligrams yetyhefu, kwanele ukubulala umntu. Ngomlinganiselo opheleleyo wetyhefu edla ngokuyikhupha ngexesha lokuzingela kwayo, kuqikelelwa ukuba yanele ukubulala abantu abangama-22..
Kukho phantse akukho zirekhodi zokulunywa ebantwini, kuba ziluma kuphela kwaye zizame ubuthi njengendlela yokuzikhusela. Oku kwenziwa xa beziva besongelwa ngumntu kwaye ekugqibeleni banquma ukuhlasela. Uninzi lokufa okubangelwa zezi nyoka ngokulunywa kwenzeka xa zidibene nabantu kwimisele engekho nzulu okanye xa zikhutshwe kwiminatha yokuloba. Kulapho basengozini kakhulu kwaye baphela behlasela.
Ngokuphathelele ukuzala, kunemikhwa ethile yokuzala. Ngokuqhelekileyo ijonge iqabane phakathi kweenyanga zikaSeptemba no-Oktobha kwaye ukuveliswa kwenziwa kanye kuphela ngonyaka. Imazi ivelisa amantshontsho amakhulu ngokwentelekiso akwaziyo ukuzinyamekela.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga neyona nyoka inetyhefu emhlabeni.
