Esinye sezici ezinhle zokuziphendukela kwemvelo kwaba ukunqotshwa kwemvelo yasemhlabeni yizilwane. Ukudlula emanzini kuya emhlabeni bekungumcimbi oyingqayizivele, ngaphandle kokungabaza, okushintshe ukukhula kwempilo emhlabeni. Le nqubo emangalisayo yenguquko ishiye ezinye izilwane zinomzimba ophakathi nendawo phakathi kwamanzi nomhlaba, oguqulwe ngokuphelele ezindaweni zasemhlabeni, kepha ngokuvamile uhlala unamathele emanzini, ikakhulukazi ukukhiqizwa kwawo.
Lokhu okushiwo ngenhla kubhekise kubantu basemanzini, ogama labo livela ngqo empilweni yabo embaxambili, emanzini nasemhlabeni, okuwukuphela kwama-vertebrate okwamanje akwazi ukuguqula isimo. Ama-Amphibian angamalungu eqembu le-tetrapod, angama-amniotes, okungukuthi, ngaphandle kwesikhwama se-amniotic, noma ngabe ngaphandle kokunye, futhi aphefumula kakhulu ngamaphaphu esigabeni sesibungu nangendlela yamaphaphu ngemuva kokuguqulwa komzimba.
Kule ndatshana kaPeritoAnimal, sifuna wazi ukuthi lezi zilwane zizala kanjani, ngoba ngesinye sezici ezizigcina zixhumene nendawo enamanzi. Funda futhi ufunde nge ukukhiqizwa kabusha kwama-amphibians.
Ukuhlukaniswa kwe-Amphibian
Njengamanje, ama-amphibian aqoqelwe eLissamphibia (lissamphibia) futhi leli qembu, lona, amagatsha noma lihlukaniswe libe kathathu:
- ukuzivocavoca: zaziwa kakhulu njengama-caecilians futhi zibonakaliswa ngokungabi namthetho. Ngaphezu kwalokho, yibo abanezinhlobo ezimbalwa kakhulu.
- Umsila (Umsila): ihambelana nama-salamanders nama-newts.
- U-Anura: ifana namaxoxo namasele. Kodwa-ke, kuyaphawuleka ukuthi lawa magama womabili awanakho ukusebenza kwe-taxonomic, kepha asetshenziselwa ukuhlukanisa izilwane ezincane ezinesikhumba esibushelelezi futhi esimanzi, kulezo ezinesikhumba esomile nesishwabene.
Ngeminye imininingwane, sikukhuthaza ukuthi ufunde le enye indatshana ekhuluma nge-Amphibian Characteristics.
Uhlobo lokukhiqizwa kabusha kwama-amphibians
Zonke lezi zilwane zinohlobo lokuzala kabusha kocansi, kepha, ziveza izindlela ezahlukahlukene zokuzala. Ngakolunye uhlangothi, yize kujwayelekile ukukholelwa ukuthi wonke ama-amphibian angama-oviparous, kuyadingeka ukucacisa lolu daba.
Ingabe ama-amphibian oviparous?
AmaCecilias anokukhulelwa kwangaphakathi, kepha angaba yi-oviparous noma i-viviparous. AmaSalamanders, ngakolunye uhlangothi, angaba nokukhulelwa kwangaphakathi noma kwangaphandle, futhi maqondana nesimo sokukhula kombungu, akhombisa izindlela eziningi ngokuya ngohlobo lwawo: amanye abeka amaqanda avundisiwe akhula ngaphandle (i-oviparity), amanye agcina amaqanda ngaphakathi komzimba wowesifazane , ukuxosha lapho kwakhiwa izibungu (ovoviviparity) kanti kwezinye izimo kugcina izibungu ngaphakathi zize ziguquke, zixoshe abantu abakheke ngokuphelele (viviparity).
Ngokuqondene nama-anurans, imvamisa i-oviparous futhi inokukhulelwa kwangaphandle, kepha kunezinhlobo ezithile zokukhulelwa kwangaphakathi futhi, ngaphezu kwalokho, amacala e-viviparity akhonjisiwe.
Injani inqubo yokwenziwa kabusha kwama-amphibians?
Sesivele sazi ukuthi ama-amphibian aveza izinhlobo eziningi zokuzala, kepha ake sazi ngokuningiliziwe zizala kanjani izilwane zasemanzini.
Ukukhiqizwa kabusha kwama-caecilians
Ama-caecilians abesilisa ane- isitho se-copulatory abesifazane abavundisa ngazo. Ezinye izinhlobo zibekela amaqanda azo ezindaweni ezimanzi noma eduze kwamanzi bese kuthi abesifazane bazinakekele. Kunezinye izimo lapho ziviviparous futhi zigcina izibungu ngaso sonke isikhathi ku-oviduct yazo, lapho zondla khona.
Ukukhiqizwa kabusha kwemisila
Ngokuqondene nama-caudates, inani elincishisiwe lezinhlobo liveza ukukhulelwa kwangaphandle, ngenkathi iningi linokukhulelwa kwangaphakathi. Owesilisa, ngemuva kokuqomisana, ushiya isidoda ngokuvamile eqabungeni noma egatsheni elithile ukuze kamuva lithathwe ngowesifazane. Maduze, amaqanda azokhulelwa ngaphakathi komzimba kamama ozayo.
Ngakolunye uhlangothi, ezinye izinhlobo zama-salamanders ahola impilo yasemanzini ngokuphelele futhi ukubekwa kwamaqanda awo kwenzeka kule ndlela, ewafaka ngobuningi noma ngamaqembu, kuthi izibungu zivele nezinsipho nomsila omise okokugcina. Kepha amanye ama-salamanders ahola impilo yabantu abadala yasemhlabeni ngemuva kokuguqulwa komzimba. Lezi zamuva zibekela amaqanda azo phansi ngesimo samaqoqo amancane, imvamisa ngaphansi kwenhlabathi emanzi, ethambile noma yeziqu ezimanzi.
Izinhlobo eziningana zivame ukugcina amaqanda azo ukuze zivikelwe futhi, kulezi zimo, i ukuthuthukiswa kwesibungu kwenzeka ngokuphelele ngaphakathi kweqanda, ngakho-ke, abantu abanesimo esifana nesabantu abadala bayachamusela kulo. Amacala abuye akhonjwe lapho owesifazane egcina khona izibungu ngesikhathi sokukhula okuphelele kuze kube sefomini yabantu abadala, lapho bexoshwa khona.
ukukhiqizwa kweselesele
Amaselesele wesilisa, njengoba sishilo ngaphambili, imvamisa zalisa amaqanda phesheya, yize zimbalwa izinhlobo ezikwenza ngaphakathi. Baheha abesifazane ngokukhishwa kwezingoma zabo, futhi lapho esekulungele, uyasondela bese okunamathiselwe kwenzeka, okuwukubeka owesilisa phezu kowesifazane, ukuze kuthi lapho ekhipha amaqanda, owesilisa avundiswe.
Ukuvuthwa kwalezi zilwane kungenzeka ngezindlela ezahlukahlukene: kokunye kungamanzi, okubandakanya izindlela ezahlukahlukene zokubeka amaqanda, kokunye kwenzeka kwizidleke zegwebu ngaphezulu kwamanzi futhi kungenziwa futhi ngendlela yasemaphandleni noma yasemhlabeni. Kukhona nezinye izimo lapho ukukhula kwesibungu kwenzeka esikhunjeni sikamama.
Kungani Amanzi Edingeka Ekuzalaneni Kwe-Amphibian
Ngokungafani nezilwane ezihuquzelayo nezinyoni, izilwane eziphila ezweni nasemanzini zikhiqiza amaqanda ngaphandle kwegobolondo noma ukwembozwa kanzima lokho kufaka umbungu walezi zilwane. Lokhu, ngaphezu kokuvumela ukushintshaniswa kwegesi nengaphandle ngoba kunamaphaphu, kunikeza ukuvikelwa okuphezulu emvelweni owomile noma ezingeni elithile lokushisa okuphezulu.
Ukuthuthuka kwe-Amphibian embryonic
Ngenxa yalokhu, ukukhula kwe-amphibian embryonic kufanele kwenzeke kufayela le- okuphakathi kwamanzi noma ezindaweni ezimanzi ukuze, ngale ndlela, amaqanda avikelwe, ikakhulukazi ekulahlekelweni umswakama, okungabulala umbungu. Kepha, njengoba sesivele sazi, kunezinhlobo zezilwane eziphila emanzini nasemanzini ezingazifaki emanzini.
Kulezi zinxushunxushu, amanye amasu ukukwenza ezindaweni ezinomswakama, ngaphansi komhlaba noma embozwe uhlaza. Bangaphinda bakhiqize inqwaba yamaqanda abandakanyeka kusisindo se-gelatinous, esibanikeza izimo ezifanele zokuthuthuka. Ngisho nezinhlobo zama-anuran ezihambisa amanzi endaweni yasemhlabeni lapho zithuthukisa khona amaqanda azo zitholakele.
Lezi zilwane ezinomgogodla ziyisibonelo esicacile sokuthi impilo ifuna izindlela zokuziphendukela kwemvelo ezidingekayo ukuze zivumelane futhi zithuthuke eMhlabeni, ezingabonakala kahle ezindleleni zazo ezahlukahlukene zokuzala, okuyizindlela eziningi ezahlukahlukene zokuqhubeka kweqembu.
Isimo sokongiwa kwe-Amphibian
Izinhlobo eziningi zezilwane eziphila ezweni nasemanzini zibalwa ohlwini lwezingozi zokuqothulwa, ikakhulu ngenxa yokuncika kwazo emizimbeni yamanzi nokuthi zingathinteka kanjani ezinguqukweni ezinkulu ezenzeka manje emifuleni, emachibini nasemathafeni ngokubanzi.
Ngalo mqondo, kudingeka izinyathelo eziqinile ukunqanda ukonakala okulethwa kuzo lezi zinto eziphilayo, ukuze kulondolozwe izilwane eziphila ezweni nasemanzini nezinye izinhlobo zezilwane ezincike kulezi zindawo zokuhlala.
Uma ufuna ukufunda izindatshana eziningi ezifana ne- Ukukhiqizwa kabusha kwe-Amphibian, sincoma ukuthi ufake isigaba sethu se-Curiosities somhlaba wezilwane.
