O nsanje ndi nyama yofuna kudziwa zambiri. Chiyambire kupezeka kwake kwakhala kovuta kwambiri kuti mugawane popeza ili ndi mawonekedwe anyama osiyana kwambiri. Ili ndi ubweya, mulomo wa bakha, imaikira mazira komanso kuwonjezera apo imadyetsa ana ake.
Ndi mitundu yopezeka kum'maŵa kwa Australia ndi chilumba cha Tasmania. Dzinalo limachokera ku Greek ornithorhynkhos, kutanthauza "wofanana ndi bakha’.
Munkhaniyi ndi PeritoZinyama tikulankhula za nyama yachilendoyi. Mudzazindikira momwe imasakira, momwe imaswanirana komanso chifukwa chake ili ndi mawonekedwe osiyanasiyana. Pitilizani kuwerenga kuti mupeze trivia yokhudza platypus.
Kodi platypus ndi chiyani?
Platypus ndi cholemera kwambiri. Monotremes ndi dongosolo la zinyama zomwe zimakhala ndi mawonekedwe a reptilian, monga kuyikira mazira kapena kukhala nawo chovala. Chophimba ndi chimbudzi kumbuyo kwa thupi komwe kwamikodzo, kugaya chakudya komanso njira zoberekera zimakumana.
Pali mitundu 5 yamoyo ya monotremes. O Platypus ndi monotremates. Monotremates ndi ofanana ndi ma hedgehogs wamba koma amagawana zodabwitsa za monotremes. Zonsezi ndi nyama zokhazokha komanso zosavuta kuzimvetsa, zomwe zimangolumikizana nthawi yokhwima.
ali ndi poyizoni
Platypus ndi imodzi mwazinyama zochepa padziko lapansi zomwe khalani ndi poizoni. amuna ali ndi kukwera m'miyendo yake yakumbuyo yomwe imatulutsa poizoni. Amatulutsidwa ndi tiziwalo timene timatulutsa. Amayi amabadwanso nawo koma samakula atabadwa ndipo amasowa asanakule.
Ndi poyizoni wokhala ndi poizoni wambiri wopangidwa ndi chitetezo chamthupi. Imapha nyama zing'onozing'ono ndipo zopweteka kwambiri kwa anthu. Zomwe anthu ogwira ntchito omwe adamva kuwawa kwamasiku angapo akufotokozedwa.
Palibe mankhwala a poizoni, wodwalayo amangopatsidwa mankhwala othandizira kuthana ndi ululu wa mbola.
Kusankhidwa kwamagetsi
Platypus amagwiritsa ntchito dongosolo lamagetsi kukasaka nyama yawo. Amatha kuzindikira zamagetsi zamagetsi zomwe zimadyedwa ndi nyama yawo ikamagwira minofu yawo. Atha kuchita izi chifukwa cha maselo amagetsi omwe ali nawo pakhungu lawo. Alinso ndi ma cell a mechanoreceptor, maselo apadera oti agwire, amagawidwa mozungulira mphuno.
Maselowa amagwira ntchito limodzi kuti atumize ubongo zomwe amafunikira kuti zizidziyendetsa popanda kugwiritsa ntchito fungo kapena kuwona. Makinawa ndi othandiza kwambiri chifukwa platypus imatseka maso ake ndikungomvera pansi pamadzi. Imamira m'madzi osaya ndipo imakumba pansi mothandizidwa ndi mphuno yake.
Wanyama yemwe akuyenda pakati pa dziko lapansi amapanga magetsi ang'onoang'ono omwe amadziwika ndi platypus. Amatha kusiyanitsa zamoyo ndi zinthu zopanda choizungulira, chomwe ndi chimodzi mwazinthu zodziwika bwino kwambiri za platypus.
Ndi nyama yodya nyama, amadyetsa makamaka nyongolotsi ndi tizilombo, tizilombo tating'onoting'ono tating'onoting'ono, mphutsi ndi ma annelids ena.
kuikira mazira
Monga tanena kale, platypus ali zokolola. Ndi nyama zomwe zimayikira mazira. Amayi amakula msinkhu kuyambira chaka choyamba cha moyo ndipo amaika dzira limodzi chaka chilichonse. Pambuyo pophatikizana, mkazi amathawira mkati manda mabowo akuya omangidwa ndi milingo yosiyanasiyana kuti asunge kutentha ndi chinyezi. Njirayi imawatetezeranso kukukwera kwamadzi ndi nyama zolusa.
Amayala kama ndi ma sheet ndi kusungitsa pakati Mazira 1 mpaka 3 10-11 millimeters m'mimba mwake. ndi mazira ang'onoang'ono omwe amakhala ozungulira kuposa a mbalame. Amakula mkati mwa chiberekero cha mayi masiku 28 ndipo atatha masiku 10-15 akhalitsa makulidwewo ana amabadwa.
Matenda aang'ono otchedwa platypus akabadwa amakhala pachiwopsezo chachikulu. Alibe tsitsi ndipo ndi akhungu. Amabadwa ndi mano, omwe amataya kanthawi kochepa, ndikungochoka kuzipilala zokhazokha.
Amayamwa ana awo
Chomwe chimayamwitsa ana awo ndichinthu chofala m'zinyama. Komabe, ma platypus alibe mawere. Ndiye mumayamwa bwanji?
Chinthu china chosangalatsa chokhudza platypus ndikuti akazi amakhala ndi zotupa za mammary zomwe zili pamimba. Chifukwa alibe mawere, sungani mkaka kudzera m'mabowo a khungu. Kudera lino la pamimba pali malo omwe mkaka uwu umasungidwa momwe amatulutsidwira, kotero kuti anawo amanyambita mkaka pakhungu lawo. Nthawi yoyamwitsa mwana ndi miyezi itatu.
Kuthamangitsidwa
ngati nyama theka-m'madzi ndi kusambira bwino. Ngakhale ili ndi miyendo inayi yoluka, imangogwiritsa ntchito miyendo yakutsogolo kusambira. Miyendo yakumbuyo imalumikiza kumchira ndikuigwiritsa ntchito ngati chiwongolero m'madzi, monga nsomba.
Pamtunda amayenda mofanana ndi chokwawa. Chifukwa chake, komanso monga chidwi chokhudza platypus, timawona kuti ali ndi miyendo yomwe ili m'mbali osati pansi monga momwe zilili ndi zinyama zina. Mafupa a platypus ndi achikale kwambiri, okhala ndi mafupipafupi, ofanana ndi a otter.
Chibadwa
Pofufuza mapu amtundu wa platypus, asayansi adapeza kuti kusakanikirana kwa mikhalidwe yomwe ili mu platypus kumawonekeranso m'ma jini ake.
Amakhala ndi mawonekedwe omwe amangowoneka mu amphibians, mbalame ndi nsomba. Koma chinthu chodabwitsa kwambiri chokhudza ma platypus ndi makina awo ogonana. Zinyama monga ife tili ndi ma chromosomes awiri ogonana. Komabe, platypus khalani ndi ma chromosomes 10 ogonana.
Ma chromosomes awo ogonana amafanana kwambiri ndi mbalame kuposa zinyama. M'malo mwake, alibe dera la SRY, lomwe limatsimikizira kuti amuna kapena akazi okhaokha. Pakadali pano sizinapezeke momwe kugonana kumatsimikizidwira mu mtundu uwu.
