Phakathi kweqela lezilwanyana ezihlala emanzini kukho isilwanyana esifuna ukwazi kakhulu esichitha ixesha elininzi lobomi baso emanzini. Imalunga triton. Ludidi lwezilwanyana eziphila emhlabeni nasemanzini olo unokuhlaziya umzimba wakhe emva kokuthatha umonakalo kokubini kwiingozi nakwimilo. Yenye yeempawu ukuba babelane salamanders, ekubeni bangabosapho olunye eyaziwa ngokuba Salamandridae. Inewt yeyomyalelo weCaudata kunye nohlobo lweTriturus.
Apha sikuxelela zonke iimpawu, indawo yokuhlala, ukutya kunye nokuveliswa kwenewt.
Zizilwanyana ezinobungakanani obuncinci. Ngoku zisi-8 iintlobo zeenewts ezaziwayo. Indawo yokusasazwa yahlulwe phakathi kwemimandla yaseYurophu, eAsia naseMelika. Zizilwanyana ezinegazi elibandayo, ngoko ke kufuneka zilawule ubushushu bazo kunye ne-ecosystem. Ngexesha lasebusika kufuneka zizimele kwindawo ezimnyama kwaye zikhwelana ngexesha lasentwasa hlobo, xa amaqondo obushushu engaphezulu.
Esinye sezizathu apho unokuxelela ukuba i-newt ivakalelwa kukuba iphakamisa intloko kunye nenxalenye yomzimba wabo ukubonisa indawo yabo ephantsi. Imibala yesi silwanyana iqiniswa ngakumbi kwindawo engezantsi njengoko kulapho kufumaneka khona izinto ezinetyhefu ezikwazi ukuzikhusela ngazo.
Ziyimizekelo edla ngokulinganisa i-avareji ye-18 centimeters ubude, kunye neemazi ezinkulu kunenkunzi. Ukumila kwayo kubude ukusuka entloko ukuya emsileni. Inamalungu ama-4 amafutshane kunye namehlo adumbileyo. Enye yeempawu ezigqama ngazo imophology yezi zidalwa ziphilayo kukuba ubude bomzimba wazo bulingana nomsila wazo.
Ulusu lunemibala eyahlukeneyo ngokuxhomekeke kwiintlobo. Eyona nto ixhaphakileyo kukuba zimibalabala phakathi komdaka kunye noluhlaza kunye namabala amnyama. Lo mbala uxhaphake ngakumbi kuba bawusebenzisa njenge-camouflage ukufihla ubumdaka namagqabi. Ngale ndlela, ziyakwazi ukuzikhusela kulo naliphi na irhamncwa elizama ukubazingela. Isisu sayo sineethowuni ezidlamkileyo ukusuka kumthubi ukuya kwiorenji kunye Kungenxa yobuninzi bezinto eziyityhefu abanazo. Le yindlela ekufuneka balumkise ngayo abachasi babo ngamandla abanokuba nawo kuwo nawuphi na umlo.
Njengezinye izilwanyana ezihlala emanzini nasemanzini, intaka iphefumla ngesikhumba sayo ize ikhuphe kabini ngonyaka. Njengoko kunye nezinye amphibians ezifana intulo, bayakwazi ukuhlaziya inxalenye yomzimba wabo xa sele zichetyiwe. Olu phawu lumangalisa kangangokuba kwanamehlo nentliziyo yalo zinokutshintsha xa ithe yaphuka.
Ngolusu, ezi zilwanyana zikhupha i-toxins kwiindawo ezinokukhuselwa kuzo naziphi na iintlobo zeentshaba. Enye yeengxaki apho ezi zilwanyana Ayinaburhalarhume kakhulu, kukuba ezi zinto zinetyhefu azisebenzi ukuba azifakwanga. Ngokuchukumisa nje ulusu yinto engenabungozi.
Umsila wayo usicaba njengokumila kwentloko yayo. Akanazo izivamvo zokubona nokuva. Kuyaziwa ukuba bahlushwa yi-myopia kwaye olu kukhubazeka lugxininiswa xa bephuma emanzini.
Indawo yokuhlala ephambili yezi zilwanyana ngamadiba kunye neendawo apho umhlaba ufume kakhulu. Xa bebancinci kwaye bekwinqanaba lombungu, bahlala emanzini. Bayakwazi ukuhlala kumachibi, imilambo, amachibi angekho nzulu kunye namaqula athile. Xa zifikelela ekuvuthweni, zikhangela imigxobhozo kunye namathambeka apho ubushushu bomhlaba bumalunga ne-12 degrees kwaye zinokuba nendawo eyaneleyo yokuhamba nokukhwela amasebe. Ifuna la masebe ukuze ikwazi ukuzondla ngokwayo.
Ukutya kwenewt kusekelwe kwizinambuzane nezinye iintlobo zezilwanyana ezikwaziyo ukuzingela, ukuluma nokwetyisa. Xa ziye zakwazi ukufumana naliphi na ixhoba, zikhetha ukutya amantshontsho azo okanye ezinye iinewt ezindala ezikwaziyo ukuzinyanga ngokukhawuleza. Ngokuqhelekileyo ukutya kwabo kusekelwe ikakhulu kwi iintshulube, amaqanda ezinye izinambuzane, imibungu, centipedes, crustaceans, arachnids kunye annelids. Ukuze zizingele ezi zilwanyana, ziyazitsibela ukuze zikwazi ukuziluma. Ngamanye amaxesha, basebenzisa ityhefu yabo ukuze bazikhusele.
Ixesha lokuzala lenziwa entlakohlaza.. Lixesha lokuba uphume ujoyine indawo yesithandathu njengoko amaqondo obushushu ethandeka ngakumbi. Ebusika bonke beza ku-hibernate kwaye, xa besinika ukunyuka kwamaqondo okushisa kunye nokuphuhliswa kweentyatyambo, bancedisa ukugxila kwiipuddles. Ngaba ezi puddles apho benza ngokwahlukeneyo ukubonakalisa ubudoda ukuphelisa ukuthandana kunye nokukhwelana okulandelayo.
Ngeli xesha lokukhwelana, iinewts zinesikhumba esiqaqambileyo. Imilebe yabo iyadumba yaye iimazi zifumbethe izisu zazo. Emva kokuthandana nokuboniswa yindoda, idibanisa imazi ukushiya i-spermatophore. Yena ngokwakhe unokuzazisa ngoxa esemanzini. Ibhinqa linokufumana isidoda kwiinewts ezininzi ngaxeshanye kuba akukho nto idibana ngokuthe ngqo ngokwasemzimbeni.
Emva kokukhwelana, imazi ijongene nokukhangela izityalo apho inokuba nenxalenye yomhlaba namanzi apho inokubeka amaqanda ayo kwaye iwagcine efumile. Liwise elinye kwigqabi ngalinye lesityalo kwaye ulisonge igqabi ngaphezulu ukuze uzikhusele. Xa kudlula ixesha elifutshane, amaqanda ayaqandusela ize imibungu iqandusele apho. Kwiintsuku zangaphambili, i-tadpoles ziintloko nje ezincinci ezinemigca emibini ebizwa ngokuba yi-rockers ezinceda ukuseka ibhalansi yazo ngelixa bequbha. Xa le migca ikhula iyanyamalala.
Umjikelo wobomi kunye nokukhula ngokwesondo kuyahluka phakathi kwentlobo nganye yenewt. Ngokuphathelele ukuziphatha kwazo, siyabona ukuba zizilwanyana ezikrelekrele kwaye zinokuzikhusela ngokulula kumarhamncwa azo. Ezi zilwanyana ubukhulu becala ziintlanzi, amasele, amaxoxo neenyoka.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nenewt.
Iminyhadala ye-mermading idibanisa i-mermaids kunye ne-mermen evela kwihlabathi liphela eSpain. Fumana imisebenzi, uqeqesho, kunye nefuthe labo lokusingqongileyo.
