Izibonelo zezilwane ezi-ovoviviparous

I- izilwane ovoviviparous yilezo ezikhula ngaphakathi kweqanda ngaphambi kokuzalwa. Kepha okuhlukanisa i-ovoviviparous ukuthi iqanda lihlala ngaphakathi kunina kuze kube yilapho umbungu usukhule ngokugcwele. Kungakho isilwane siphuma eqandeni ngemuva nje kokubekwa kweqanda. Ikwazi nokuchanyuselwa eqandeni elingaphakathi komzimba kamama bese kamuva izala.

Kubalulekile ukuhlukanisa izilwane ezi-ovoviviparous kwezinye izilwane ezikhulisa nemibungu yazo ngaphakathi kwamaqanda, i- oviparous. Lezi zokugcina zifaka amaqanda azo kwimvelo yangaphandle ekuqaleni kokukhula kombungu. Ngamanye amagama, imibungu ikhula ngaphandle komzimba womama.

Kufanele futhi bahlukaniswe ne- izilwane ezi-viviparous, okuyilabo umbungu wabo okhula ngaphakathi emzimbeni womama, njengezilwane ezincelisayo. Yize i-viviparous nayo ikhulisa umbungu ngaphakathi, umehluko ukuthi njengoba umbozwe yigobolondo, awunakondliwa ngqo ngumama.

Lokho kusho ukuthi:

Iphuzu elijwayelekile phakathi kwe-ovoviviparous ne-oviparous: Umbungu uvikelwe yigobolondo.
Iphuzu elijwayelekile phakathi kwe-ovoviviparous ne-viviparous: Ukuvundisa kwenzeka emzimbeni womama, lapho umbungu nawo ukhula khona.

Izibonelo zezilwane ezi-ovoviviparous

Ushaka omhlophe: Uhlobo lukashaka omkhulu futhi onamandla. Inomlomo oqoshiwe. Kufanele ibhukude njalo (ayikwazi ukuhlala izolile) ukuze iphefumule futhi intante, ngoba ayinaso isinye sokubhukuda. Imibungu idla ngesikhupha. Lo shaka usuke engazaleli amaqanda kepha amachwane amancane aqandusela ngaphakathi kunina bese ezalwa esekhulile.
I-Boa constrictor: Isirhubuluzi engalinganisa phakathi kuka-0.5 no-4 wamamitha, ngokuya ngama-subspecies. Ngaphezu kwalokho, abesifazane bakhulu kunabesilisa. Ibomvu futhi imhlophe, noma ibomvu futhi nsundu, ngokuhlukahluka kuye nge-subspecies. Siyakhwelana ngesikhathi semvula. Ukumitha kwayo kuthatha izinyanga ezimbalwa. Ukuchanyuselwa kwamaqanda kwenzeka ngaphakathi emzimbeni womama, kuchamisela inzalo esivele isivele ikhulile.
Uju lwezinyosi: Uhlobo lukashaka omncane, olufinyelela ngaphezu nje kwemitha ubude. Kubonakala ngokuba nezinsipho ezinobuthi ebusweni bomzimba. Iwuhlobo lukashaka oluningi kakhulu kepha ngokusatshalaliswa okuvinjelwe. Udoti wokuzala uncike ebusungwini besifazane, ngoba okuvamile imibungu engu-1 kuye kwengu-20 ekukhulelweni ngakunye, kodwa abesifazane abakhulu bangaba nodoti abaningi. Zizalwa zivela eqandeni.
I-Stingray (ingubo enkulu): Ihlukaniswe nezinye izinhlobo ngoba ayinaso isitinyela esinobuthi emsileni waso. Futhi ngenxa yobukhulu bayo obukhulu. Uhlala ezilwandle ezipholile. Iyakwazi ukweqa ukuphuma emanzini. Ngesikhathi sokuzala, abesilisa abaningana bashela owesifazane. Ukuze omunye wabo afinyelele ekulandeleni, kufanele abulale abancintisana naye. Kulinganiselwa ukuthi isikhathi amaqanda ahlala ngaphakathi kowesifazane singaba ngaphezu kwezinyanga eziyishumi nambili. Unengane eyodwa noma ezimbili ngodoti ngamunye.
Anaconda: Uhlobo lohlobo lwenyoka ecindezelayo. Ingalinganisa amamitha ayishumi ubude. Yize ingahlali eqenjini kodwa ngendlela eyedwa, lapho insikazi ifuna ukuzala ingaheha iduna ngokukhipha ama-pheromones. Kudoti ngamunye kuzalwa amantombazane aphakathi kuka-20 no-40, cishe angama-60 cm ubude.
Isaladi laseSuriname: I-Amphibian ehlala ezindaweni ezishisayo nezishisayo. Iphawuleka ngomzimba wayo oyisicaba nenhloko yayo eyisicaba, engunxantathu. Umbala wayo mpunga oluhlaza okotshani. Luhlobo olukhethekile lwesilwane se-ovoviviparous, ngoba ukuvundisa kwenzeka ngaphandle komzimba kanina. Uma sesikhulelwe, owesifazane uphinde afake amaqanda emzimbeni wakhe. Ngokungafani nezinye izidalwa eziphila emanzini nasemanzini, ezizalwa njengezibungu bese zibhekana nesimo sokuguquguquka, leli thswa lenza ukukhula kwalo njengesibungu ngaphakathi kweqanda, kanti abantu abazalwayo sebenomumo wokugcina.
I-Platypus: Kuthathwa njengesilwane esincelisayo, kepha sibekela amaqanda, ngakho-ke singabizwa nangokuthi i-ovoviviparous. Kuyisilwane esisemanzini esihlala empumalanga ye-Australia naseTasmania. Iphawuleka ngokubukeka kwayo okuthile, inempumu efana nomlomo wedada, umsila onjenge-beaver, nemilenze efana ne-otter. Unobuthi.
UJackson Trioceros: Izinhlobo zezinyamazane ze-ovoviviparous. Inezimpondo ezintathu, yingakho ibizwa ngokuthi "ama-trioceros". Uhlala eMpumalanga Afrika. Lezi zinsana zizalelwa kudoti ophakathi kwamakhophi ayisishiyagalombili kuya kwangama-30, ezimitha izinyanga eziyisithupha.
I-Hippocampus (seahorse): Luhlobo oluthile lwe-ovoviviparous, ngoba amaqanda awavuthwa ngaphakathi komzimba wowesifazane kepha emzimbeni wesilisa. Ukukhulelwa kwenzeka ngenkathi owesifazane edlulisa amaqanda esikhwameni sowesilisa. Isaka lifana nelama-marsupials, okungukuthi, lingaphandle nangaphandle.
Isixwayiso (ICrystal shingles): Isilwane esithile, ngoba siyisibankwa esingenamlenze. Lokho kusho ukuthi ngokubukeka kufana nenyoka. Kodwa-ke, kuyaziwa ukuthi yisibankwa ngoba kukhona izinsalela zamathambo aso emzimbeni aso anezici zezibankwa. Futhi, inamajwabu amehlo ahambayo, ngokungafani nezinyoka. Kuyisilwane esihuquzelayo esihlala eYurophu futhi esingafika ku-40 cm, noma ku-50 cm kwabesifazane. Ukuzala kwenzeka entwasahlobo. Ngemuva kwezinyanga ezi-3 noma ezi-5 zokukhulelwa, insikazi izalela amaqanda nentsha esekhulile ngaphakathi, bese ukuqanduselwa kwenzeka ngokushesha.
