Izilwanyana ezanyisayo

Umxholo

• Imizekelo yezilwanyana ezanyisayo
• Eminye imizekelo yezilwanyana ezanyisayo
• Landela ngo:

Inkqubo ye- izilwanyana Zizilwanyana ezibonakaliswa yinto yokuba iimazi zondla abancinci ngokuvelisa ubisi amadlala.

Babonakala ngo:

• UmqoloNjengazo zonke izilwanyana ezinethambo lomqolo, izilwanyana ezincancisayo zinomqolo.
• AmniotesUmbungu uvelisa iimvulophu ezine ezikwi-chorion, allantois, amnion kunye ne-yolk sac. Ujikelezwe zezi mvulophu, umbungu ukwindawo enamanzi apho uphefumla kwaye wondle.
• Ukubuyela ekhaya: Ikwabizwa ngokuba ngu "de igazi elishushu”Ngaba zizilwanyana ezinako ukulawula ubushushu bazo nokuba bubuphi na ubushushu. Banesakhono sokulawula ubushushu emzimbeni ngezinto ezithile zangaphakathi ezinje ngokutshisa amanqatha, ukukhefuzela, ukonyusa okanye ukunciphisa ukuhamba kwegazi, okanye ukungcangcazela.
• Iiplacental viviparousNgaphandle kwemeko ezimbalwa, zihlala zihleli ziphantsi. Imveku engekazalwa ikhula iyakheke ngokukodwa kwisibeleko sowasetyhini. Ukwahluka yile marsupials, ezizizilwanyana ezincancisayo kunye ne-viviparous, kodwa ezingenayo i-placenta kwaye umntwana uzalwa ngaphambi kwexesha. Enye into engafaniyo nee-monotremes, ezizizilwanyana ezanyisayo ezizalela amaqanda, oko kukuthi, zinokuzala kwakhona kwe-oviparous.
• Amazinyo: Ithambo elinye lomhlathi ocacisa ngokakayi.
• Ukuva Phakathi kunye nomxokelelwane wethambo owenziwe sisando, incus kunye nesiraphu.
• IinweleNangona kumanqanaba ohlukeneyo, ukuba iintlobo ezahlukeneyo zithathelwa ingqalelo, izilwanyana ezanyisayo zineenwele kumalungu athile omzimba, anjengeebristles zeetetan ezijikeleze umlomo.

Imizekelo yezilwanyana ezanyisayo

• Umnenga: Yi-cetacean, oko kukuthi, isilwanyana esanyisayo esiqhelaniswe nobomi bamanzi. Ngokungafaniyo neentlanzi, ii-cetaceans zinokuphefumla kwemiphunga. Banomzimba ofanayo nolo weentlanzi, kuba bobabini baneemilo ze-hydrodynamic.
• Ihashe: Sisilwanyana esanyisayo se-perosidactyl, oko kukuthi, sineminwe engaqhelekanga ephela ngamanqina. Imilenze neempuphu zazo zizinto ezingenakubonwa nakweziphi na izinto eziphilayo. Ngaba iyadla.
• Itshimpanzi: I-Primate yemfuza isondele kakhulu emntwini, ebonisa ukuba zombini ezi ntlobo zinokhokho omnye.
• Ihlengethwa: Kukho iintlobo zehlengesi zaselwandle kunye needonphin zomlambo. Ziyi-cetaceans, njengeminenga.
• Indlovu: sesona silwanyana sikhulu sasemhlabeni. Banokuba nobunzima obungaphezulu kwamawaka e-7 eekhilo kwaye nangona nge-avareji bahlala belinganisa iimitha ezintathu ukuphakama. Ezinye iindlovu ziphila iminyaka engama-90. Bayakwazi ukunxibelelana ngokungcangcazela emhlabeni.

• IkatiNangona inja isenokubonakala ngathi sisilwanyana sasekhaya ngokugqwesa, ikati ihleli nabantu ngaphezulu kwe-9 lamawaka eminyaka. Banobungangamsha obukhulu, ngenxa yokuguquguquka kwemilenze yabo, ukusetyenziswa komsila kunye ne "right reflex" yabo ebavumela ukuba bajike umzimba wabo emoyeni xa bewa kwaye ngalo lonke ixesha bahlala bewa kwimilenze yabo, ngenxa yokungaqheleki kwabo. ukumelana nobhetyebhetye ukuwa kwiindawo eziphakamileyo.
• Gorilla: Yeyona primate inkulu. Ihlala kumahlathi aseAfrika. Zizityalo ezitya uhlaza kwaye iijini zazo zingama-97% ngokufanayo nofuzo lomntu. Bangakwazi ukufikelela kwi-1.75 m ukuphakama kunye nobunzima ukuya kwi-200 kg.
• Imvubu eqhelekileyo: Isilwanyana esanyisayo sasemanzini, oko kukuthi, sichitha imini emanzini okanye eludakeni kuphela ebusuku siye emhlabeni siyokukhangela amayeza esiza kuwatya.Kukho ukhokho oqhelekileyo phakathi kwemvubu kunye ne-cetaceans (eyimikhomo kunye ne-porpoises, phakathi kwabanye). Inokuba nobunzima obufikelela kwiitoni ezintathu. Nangona kunjalo, ngenxa yemilenze yabo enamandla, banokubaleka ngokukhawuleza ngevolumu yabo enkulu, ngesantya esifanayo njengomntu ophakathi.
• Indlulamthi: Sisilwanyana esanyisayo se-artiodactyl, Oko kukuthi, iziphelo zaso zineminwe elinganayo. Bahlala e-Afrika kwaye zezona zilwanyana ziphakamileyo emhlabeni, zifikelela kubude obuphantse bube ziimitha ezi-6. Ihlala kwindalo eyahlukeneyo, enje ngamathafa, ingca kunye namahlathi avulekileyo. Ukuphakama kwayo kuthathwa njengokuhlengahlengisa okuvumela ukuba ifikelele kumagqabi emithi angenakufikelelwa zezinye izilwanyana.
• Ingonyama yolwandle: Sisilwanyana esanyisayo saselwandle, sosapho olunye lwamatywina kunye neewalrus. Njengazo zonke izilwanyana ezanyisayo zaselwandle, ineenwele kwezinye iindawo zomzimba ezifana nasemlonyeni kunye nongqameko lwamafutha ukunciphisa ilahleko yobushushu.
• IngonyamaIsilwanyana esanyisayo esihlala kumazantsi e-Sahara e-Afrika nakumntla-ntshona we-India. Luhlobo olusemngciphekweni wokuphela, uninzi lweesampulu zihlala koovimba. Sisilwanyana esidla inyama, irhamncwa ikakhulu kwezinye izilwanyana ezikhulu ezifana ne-wildebeest, impala, iqwarha, inyathi, i-nilgos, ihagu zasendle kunye nexhama. Ukutya ezi zilwanyana, zihlala zizingela zingamaqela.

• Ilulwane: Zizilwanyana ezanyisayo kuphela ezinamandla okubhabha.
• Iimbumba: Izidalwa ezincancisayo ezihlala emanzini, kodwa zingalahlekwa ziinwele njengezinye izilwanyana ezanyisayo Zitya iintlanzi, iintaka, amasele nononkala.
• Iplatypus: Monotreme, Oko kukuthi yenye yezilwanyana ezincancisayo ezimbalwa (kunye nee-echidnas) ezibeka amaqanda. Inetyhefu kwaye iyabetha ngokubonakala kwayo, kuba nangona inomzimba ogqunywe ziinwele njengoninzi lwezilwanyana ezanyisayo, inempumlo enomilo ofana ncam nomlomo wamadada. Bahlala kuphela kwimpuma yeOstreliya nakwisiqithi saseTasmania.
• Ibhere eliyiphola: Esona silwanyana sikhulu sasemhlabeni sikhona. Ihlala kwiindawo ezinqabileyo zenyakatho ye-hemisphere. Umzimba wakho uhlengahlengisiwe kumaqondo obushushu asezantsi ngenxa yemigangatho yeenwele namafutha.
• Imikhombe: Izilwanyana ezincancisayo ezihlala eAfrika nase Asia. Zibonakala lula ezimpondweni kwiimpumlo zazo.
• Ukubangumntu: Abantu baphakathi kwezilwanyana ezanyisayo kwaye sabelana ngeempawu zazo zonke. Iinwele zomzimba sisiqalo soboya bezinye izilwanyana.
• IngweIsilwanyana esanyisayo esihlala eAsia. Isilwanyana esikhulu, kungekuphela nje kwezilwanyana ezincinci kunye neentaka, kodwa nakwezinye izilwanyana ezifana neengcuka, ii-hyenas kunye neengwenya.

• Inja: Yinto ephantsi kwengcuka, iyi-canid. Kukho iintlobo ezingaphezu kwe-800 zezinja, ezigqitha naziphi na ezinye iintlobo. Uhlobo ngalunye lubonisa umohluko obonakalayo kuzo zonke iimpawu zalo, ukusuka kwidyasi kunye nobukhulu ukuya ekuziphatheni kunye nokuphila ixesha elide.

Yintoni egqithisile:

• Izilwanyana zasemanzini
• Izilwanyana ezinomqolo
• Izilwanyana ezingenamqolo
