Eqenjini lezilwane ezihlala emanzini kukhona isilwane esifuna ukwazi esichitha ingxenye enkulu yokuphila kwaso emanzini. Imayelana i-triton. Kuyisigaba sezilwane ezihlala emanzini angakwazi ukuvuselela umzimba wakhe ngemva kokulimala kokubili ezingozini nasekulweni. Kungenye yezici ababelana ngazo nama-salamanders, ngoba bangabomndeni ofanayo owaziwa ngokuthi i-Samandridae. I-newt ingeyohlelo lwe-Caudata kanye nohlobo lwe-Triturus.
Lapha sikutshela zonke izici, indawo yokuhlala, ukudla kanye nokuzala kwe-newt.
Ziyizilwane ezincane. Njengamanje ziyisi-8 izinhlobo zama-newt ezaziwayo. Indawo yokusabalalisa ihlukaniswe phakathi kwezindawo zaseYurophu, e-Asia naseMelika. Ziyizilwane ezinegazi elibandayo, ngakho-ke zidinga ukulawula izinga lokushisa kwazo ne-ecosystem. Ngesikhathi sasebusika zidinga ukucasha ezindaweni ezimnyama bese zikhwelana entwasahlobo, lapho amazinga okushisa esephezulu.
Esinye sezizathu ongabona ngazo ukuthi i-newt izizwa isongelwa ukuthi iphakamisa ikhanda nengxenye yomzimba ukuze ibonise indawo yayo ephansi. Imibala yalesi silwane iyaqina engxenyeni engezansi kwazise yilapho kutholakala khona izinto ezinobuthi ezikwazi ukuzivikela ngazo.
Ziyizibonelo ezivame ukukala isilinganiso esingamasentimitha angu-18 ubude, kanti abesifazane babe bakhudlwana kunabesilisa. Ukuma kwayo kubude ukusuka ekhanda kuya emsileni. Inezitho ezimfushane ezi-4 namehlo aqhumile. Esinye sezici i-morphology yalezi zidalwa eziphilayo egqamayo ukuthi ubude bemizimba yazo bulingana nomsila wazo.
Isikhumba sinemibala eyahlukene kuye ngokuthi hlobo luni. Into ejwayeleke kakhulu ukuthi inemibala ephakathi kwensundu kanye neluhlaza okotshani enamabala amnyama. Lo mbala ugcwele kakhulu ngoba bawusebenzisa njenge-camouflage ukuze bacashe odongeni nasemaqabungeni. Ngale ndlela, ziyakwazi ukuzivikela kunoma yisiphi isilo esizama ukuzingela. Isisu sayo sinamathoni agqamayo asukela kophuzi kuye kuwolintshi futhi Kungenxa yobuningi bezinto ezinobuthi ezinazo. Lena yindlela okumele baxwayise ngayo izitha zabo ngamandla abangaba nawo kunoma iyiphi impi.
Njengezinye izilwane ezihlala emanzini nasemanzini, i-newt iphefumula ngesikhumba sayo bese iphuma kabili ngonyaka. Njengakwamanye ama-amphibians afana nesalamander, ayakwazi ukuvuselela ingxenye yomzimba wawo lapho ecwiywe. Lesi sici simangalisa kangangokuthi ngisho namehlo aso nenhliziyo kungashintsha uma kwenzeka inqunywe.
Ngesikhumba, lezi zilwane zikhipha ubuthi ezindaweni ezingavikeleka kunoma yiziphi izinhlobo zesitha. Enye yezinkinga lezi zilwane Azinawo ulaka kakhulu, wukuthi lezi zinto ezinobuthi azisebenzi uma zingangenwanga. Ngokuthinta nje isikhumba kuyinto engenabungozi.
Umsila wayo uyisicaba njengokuma kwekhanda layo. Akanazo izinzwa ezithuthuke kakhulu zokubona nokuzwa. Kuyaziwa ukuthi bahlushwa i-myopia futhi lokhu kukhubazeka kugcizelelwa lapho bephuma emanzini.
Indawo eyinhloko yalezi zilwane amachibi kanye nezindawo lapho umhlaba unomswakama kakhulu. Lapho zisencane futhi zisesigabeni sezibungu, zihlala emanzini. Bayakwazi ukuhlala emachwebeni, emifudlaneni, emachibini angashoni nasemithonjeni ethile. Lapho sebevuthiwe, babheka amaxhaphozi nemithambeka lapho izinga lokushisa lomhlabathi libalelwa ku-12 degrees futhi bangaba nendawo eyanele yokuhamba nokukhuphuka amagatsha. Idinga la magatsha ukuze ikwazi ukuzondla yona.
Ukudla kwe-newt kusekelwe ezinambuzaneni nakwezinye izinhlobo zezilwane ezikwazi ukuzingela, ukuluma nokugaya. Lapho sezikwazile ukuthola noma iyiphi inyamazane, zikhetha ukudla imidlwane yazo noma ezinye izinja ezindala ezikwazi ukuwelapha ngokushesha. Ngokuvamile ukudla kwabo kusekelwe ikakhulukazi izikelemu, amaqanda ezinye izinambuzane, izibungu, centipedes, crustaceans, arachnids kanye annelids. Ukuze zizingele lezi zilwane, ziziphonsela phezu kwazo ukuze zikwazi ukuziluma. Kwesinye isikhathi, basebenzisa ushevu ukuze bazivikele.
Isikhathi sokuzala senzeka entwasahlobo.. Sekuyisikhathi sokuphuma ujoyine indawo yesithupha njengoba amazinga okushisa emnandi kakhulu. Kubo bonke ubusika ziyalala futhi, lapho izinga lokushisa likhuphuka kanye nokukhula kwezimbali, zisiza ukugxilisa ama-puddles. Ingabe lezi zimfucumfucu lapho zenza ngokuhlukana kwazo ukukhombisa ubudoda bokunqamula ukuqoma nokukhwelana okwalandela.
Ngalesi sikhathi sokukhwelana, ama-newt anesikhumba esikhanya kakhulu. Izindebe zabo ziyavuvukala futhi ezesifazane zifutha izisu zazo. Ngemva kokuqomisana nokuboniswa yindoda, ijoyina insikazi ukushiya i-spermatophore. Yena uqobo angabethula esemanzini. Owesifazane angathola isidoda kumanewt amaningana ngesikhathi esisodwa njengoba kungekho ukuxhumana okuqondile ngokomzimba.
Ngemva kokukhwelana, insikazi yiyo ebhekele ukubheka izitshalo lapho ingaba nengxenye yomhlaba namanzi lapho ingabekela khona amaqanda ayo futhi iwagcine emanzi. Beka elilodwa eqabungeni ngalinye lesitshalo bese ugoqa iqabunga ukuze uwavikele. Lapho isikhathi esifushane sidlula, amaqanda achanyuselwa futhi izibungu zichanyuselwa lapho. Ezinsukwini zakuqala, oshobishobi bangamakhanda nje amancane anemigqa emibili ebizwa ngokuthi ama-rocker esiza ukulinganisa lapho ebhukuda. Uma lemigqa ikhula iyanyamalala.
Umjikelezo wempilo kanye nokuvuthwa kwezocansi kuyahluka phakathi kwezinhlobo ze-newt. Mayelana nokuziphatha kwazo, siyabona ukuthi ziyizilwane ezihlakaniphe kakhulu futhi zikwazi ukuzivikela kalula ezilwaneni ezizidlayo. Lezi zilwane ezidla ezinye ikakhulukazi izinhlanzi, amaxoxo, amaselele nezinyoka.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana ne-newt.
Imicimbi ye-mermading ihlanganisa ndawonye izinsalela kanye nezilwane ezivela emhlabeni wonke eSpain. Thola imisebenzi, ukuqeqeshwa, kanye nomthelela wazo kwemvelo.
Uma ungumthandi wama-amphibians futhi unezilwane ezifuywayo, kungenzeka wazi ngamanewts. Zingezinye zezilwane ezizijwayela kangcono nempilo ekuthunjweni futhi zinikeza umbala ongenakuqhathaniswa nokubukisa. Yilokho okwenzeka ku-fire-bellied newt, ebonakala ...
E-Peninsula yase-Iberia kunenani elikhulu lezilwane ezihlukile (zitholakala eSpain kuphela). Enye yazo i-pygmy newt, eyaziwa kancane, nokho ingenye yezinhlobo ze-urodele zomdabu. Uma ufuna ukwazi izici ze-pygmy newt, lapho izindawo zaseSpain evame ukuhlala kuzo, ukuthi idla ini...
Phakathi kwezilwane ezifuywayo, enye eyaziwa kakhulu eYurophu yilokho okubizwa ngokuthi i-palmate newt. Kuyisilwane esihuquzelayo esisengozini yokushabalala, ikakhulukazi ezinye izinhlobo ezincane. Uma ufuna ukwazi okwengeziwe nge-palmate newt, njengezici zayo, indawo yokuhlala, ukudla noma ukuzala, qiniseka ukuthi uthola...
E-Spain singazizwa siziqhenya ngokuba nezinhlobo ezihlala ezweni lethu kuphela. Yilokho okwenzekayo ngePyrenean newt, isilwane esihlala emanzini nasemanzini esitholakala enyakatho yeSpain kuphela. Uma ufuna ukwazi ukuthi i-Pyrenean newt injani, ungayithola kuphi eSpain, ukuthi idla ini kuleyo ndawo, futhi...
I-marbled newt ingenye yezilwane ezihlala emhlabeni wonke ezigqama kakhulu e-Europe ngenxa yemibala yayo egqamile. Nakuba kungavunyelwe ukuba nayo njengesilwane esifuywayo, iyisilwane esizijwayeza kahle kakhulu lapho indawo yokuhlala ifana neyakhe. Uma ufuna ukwazi ukuthi i-marbled newt injani, ukuthi ihlala kuphi, ukudla kwayo nokukhiqizwa kwayo, unga...
Enye yezilwane ezihlala emanzini ezaziwa kakhulu kuyo yonke iNhlonhlo Yase-Iberia iyinewt yase-Iberia. Lesi silwane esincane, esijwayele kakhulu ukuhlala emanzini kunangaphandle, sitholakala ezingxenyeni ezihlukahlukene zeSpain nasemazweni angomakhelwane asePortugal. Kodwa-ke, akuvamile njengesilwane esifuywayo, nakuba singaba nayo. Thola ukuthi bayini…
