Egg-kuisa mhuka: rondedzero, unhu, maberekero uye mhando

Munhu wose anoziva kubva zvezvaidzidziswa ari mhuka. Uye haana munoziva kuti zai-kuisa mhuka - siyanei dzemhuka mhando, rinorarama chete munharaunda imwe kondinendi - Australia? Ngatitarisei mhuka mashoko ichi chinokosha.

kuvhura oviparous

Nokuti kuvapo yakasiyana kwayo mhuka kuti dzinoberekera, mazai vysizhivaya mhando imwe nguva refu, haana kuzivikanwa. Shoko rokutanga pamusoro zvisikwa izvi vakauya Europe iri XVII remakore. Panguva ino mune Australia akaunza ganda anoshamisa chisikwa ane muromo, ane mvere. Waiva Dhadha-billed platypus. Zaspirtovannye Somuenzaniso akaunzwa chete pashure pemakore 100. Chokwadi chokuti platypus ari kushanda zvausingafaniri uranda. Ndivo zvakaoma chaizvo kuti asike zvinhu nokuda chokufambisa. Saka, kuongorora vakanga chete mazvinogara.

Zvichitevera yawanikwa platypus vakagamuchira mashoko chimwe chisikwa chine muromo, asi zvino akafukidzwa tsono. nyoka iyi. Masayendisiti refu nharo pamusoro izvo kirasi kuti patsanura zvisikwa izvi zviviri. Ndawana kuti platypus uye echidna, zai-kuisa mhuka, anofanira akatamira kune yoga bato. Saka pakanga Boka monotremes, kana cloacal.

zvinoshamisa platypus

Anowanikwa rwayo kuva usiku. Richiparadzirwa platypus chete muAustralia uye Tasmania. The mhuka aigara hafu mumvura, i.e. munhu zvibereko mumakomba anovaka mumvura uye panyika, mvura iri zvokudya. Pane zvishoma - kusvika 40 masendimita. Chine, sezvo kare ambotaurwa, dhadha mhino, asi zviri nyoro uye yakafukidzwa nematehwe. Chete nechitarisiko kwazvo zvakafanana Dhadha. Panewo 15-padiki muswe, sezvinoita Beaver muswe. Netsoka dzakapfava vane webbing, asi havazivi kuvhiringidza platypus kufamba pasi uye kuchera gomba zvakakwana.

Sezvo genitourinary maitiro uye dumbu kunze mhuka imwe mugomba, kana cloaca kuti anonzi munhu chete pfungwa - cloacal. Sezvineiwo, platypus swims, kusafanana vanhuwo mhuka, uchishandisa mberi tsoka uye neshure kushanda booster. Kunze chinhu chimwe, ngativhurei tifunge sei reproduces.

kubereka platypus

Interesting chokwadi: pamberi mhuka ruminant vanowira 10-zuva kuhwanda, uye chete ipapo kutanga kuberekesana mwaka. Rinotora anenge ose matsutso, kubva August November. Platypus naye mumvura, uye pashure muvhiki mbiri imwe, hadzi anoteya avhareji mazai maviri. Vanhurume havabatanidzwi akazotevera upenyu mwana.

The hadzi anovaka chaiwo buri (15 metres) kuti panosangana panoperera mugero wacho. Lining mbishi mashizha madzinde kuramba mumwe mwando, saka kuti mazai regai akaoma. Sezvineiwo, nokuti dziviriro uyewo anovaka chipingamupinyi Ukobvu 15 masendimita.

pashure chete regadziriro basa iye mazai ari mudendere. Platypus zai madhoo, curled kumusoro vakavapoteredza. Pashure pemazuva 10, vana vanoberekwa, kupfeka uye bofu, sezvinoita mhuka dzose. The hadzi chikafu mwana mukaka, inoyerera ichibva kure chaipo mvere paburi uye vanounganidza. Kids vachananzva mukaka uye nokudaro zvokudya. Kudyisa anopfuurira inenge 4 months, uye ipapo vana kudzidza zvadzinofura hwavo. Kuti akapa nzira ruminant ichi mhando zita "zai-kuisa mhuka."

chechienzi nyoka

Nyoka - chete zai-achiisa mhuka. nepanyika iri ari maduku saizi, richisvika kusvika 40 masendimita. Rinogara muna Australia, Tasmania uye muzvitsuwa New Guinea. By mhando mhuka ichi chakafanana tyoni, asi ane refu yakamanikana muromo usingabereki kupfuudza 7.5 cm. Sezvineiwo, nenyoka haina meno, uye anobata zvakatapwa ane refu Sticky rurimi.

venyoka muviri chakafukidzwa pamusoro shure uye mativi spines, iyo yakaumbwa kubva dzemakwiringwindi shinda. Shinda anofukidza mudumbu, musoro uye makumbo hwemhuka. Echidna ari dzakashandisa imwe mhando zvokudya zvakakwana. Iye regales mujuru, masvosve uye diki nezvipembenene. It anotungamirira nezuva upenyu, asi zvakaoma. Chokwadi ndechokuti ane pasi muviri tembiricha kusvika 32 madhigirii, uye haaribvumiri kutakura achideredza kana kumutsa ambient tembiricha. Muchiitiko chino, nyoka anova usimbe uye ugere pasi miti kana dzinorara kwenguva refu.

Method kubereka venyoka

Echidna - zai-kuisa mhuka, asi izvozvo zvakanga chete pakutanga pamusoro XXI remakore. Interesting yokudanana echidnas. Per hadzi Nhoroondo kusvika 10 varume. Kana asarudza kuti akagadzirira zvisangane, chaanovata pamusoro kumusana kwake. Vanhurume iri akachera mugero kumativi vanotanga kurwira ushasha. Kurara nemukadzi akanga akasimba.

Gestation rinovapo mazuva 28 uye rinopera pakuonekwa zai, iyo zvinopfakanyika hadzi mazana matanhatu. Zviri achiri asina pachena sei hadzi zai kunoita kupinda muhomwe, asi pashure pemazuva 10 mwana anouya. Hatchling anouya munyika haisi zvakazara kuumbwa.

mwana

Kuberekwa mwana zvakafanana zvikuru kuberekwa vaduku marsupials. Naivowo vari yokupedzisira kukura mai bhegi iri uye kusiya izvozvo sezvo vakuru, takagadzirira yakazvimirira vapenyu. Interesting chokwadi: marsupial mhuka zvinogarawo mune Australia oga.

Saka, pane kuti mwana echidna? Iye bofu uye hauna kupfeka, hindquarters ake havana yakatanga, akavhara maziso Rakaunyana firimu, uye chete pamberi netsoka dzakapfava zvakaumbwa minwe. Kuti vasvike kune mukaka, mwana inodiwa 4 kwemaawa. Zvinofadza kuti pane 100-150 kubva kuti kusunungurwa kuburikidza anokosha bvudzi mukaka muhomwe muna mai. Baby chete anofanira kusvika kwavari.

The mwana ari amai homwe inenge 2 months. Iye pakarepo anowana uremu nokuda zvinovaka mukaka. Mukaka ndiko chete nyoka, iro rine vaaleanpunainen ruvara nokuda yakawanda simbi mairi. Kudyisa kuramba 6.5 mwedzi. Majaya kudzidza kubereka zvokudya zvavo pachavo.

Mhando dzakasiyana-siyana spiny Nehwiribidi

Mhando dzakasiyana-siyana spiny Nehwiribidi - nderimwe mhuka zai-achiisa. chisikwa Iri yakakura zvikuru kupfuura vazvo. Tunogara kuchamhembe chitsuwa New Guinea uye Indonesia. Dimensions mune mhando spiny Nehwiribidi kumanikidzira 80 masendimita apo pakurema kwayo kunosvika 10 makirogiramu. In chitarisiko rinotsvaka semvumbi, asi muromo ndiye yakareba uye mapfupi zvikuru tsono. Anogara ari makomo nzvimbo uye anodyisa kunyanya makonye. Sezvineiwo maumbirwo nomumukanwa akasiyana spiny Nehwiribidi: rurimi wake ane mazino, uye kurishandisa, iye anokwanisa kutsenga zvokudya kwete chete, asi, sezvambotaurwa, kunyange matombo.

mhando iyi zvikuru havaratidzi vadzidza, nokuti anogara kumakomo. Asi vakaona kuti mhuka havazotadzi mufambo chero ekunze, regai dzinorara kwenguva refu uye anokwanisa waidzora yavo muviri tembiricha. Kubereka kuti zai-nokuisa mhuka, iyo inosanganisira akasiyana spiny Nehwiribidi, yakafanana kuti mamwe maviri marudzi. Zvinotora chimwe chete zai kuti anoiswa muhomwe pamusoro dumbu rake, uye zvinogara mwana wacho mukaka.

okufananidza unhu

Zvino ngatitarise mhando mhuka mhenyu kondinendi Australian. Saka, chii chiri musiyano oviparous, marsupials uye placental mhuka? Chokutanga, ndinofanira kutaura kuti mhuka zvose zvokudya vadzo nomukaka. Asi pakuonekwa vana vechiedza ine musiyano hombe.

mhuka Oviparous vane chinhu chimwe chakafanana. Ivo mazai seshiri uye hatch chaiyo yavo. Mushure pakuonekwa mwana amai unobereka mukaka kuti vana vadye. Zvinofanira kucherechedzwa kuti vechiduku vasingadi muchayamwa mukaka, uye vachinanzva pamwe grooves ari munhukadzi ari mudumbu. Pasina munyatso iri kupatsanurwa pane dzimwe zai-achiisa mhuka.

Marsupial mhuka vane homwe vavaiti, saka zita ravo. Bag iri mudumbu kuti vanhukadzi. Achangoberekwa, kusvika pariri, awana munyatso uye sezvo yakaturikwa payo. Nyaya iripo ndeyokuti vana vanoberekwa unformed uye rinoitwa ari amai homwe kwemwedzi inoverengeka kupedza kukura kwayo. Zvinofanira akati kuti zai-kuisa mhuka uye marsupials iyi neruremekedzo zvakafanana. Kids echidnas uye mhando spiny Nehwiribidi vanoberekwa underdeveloped woiswa rudzi zvisaririra muchirugu.

Uye chii chingataurwa placental mhuka? Vana vavo vari vavakabereka vakanyatsosvika nokuda pamberi placenta iri dumbu. It kunoitika nokuda zvokudya uye mwana kukura kwacho. Unorema mhuka ndowenyika placental.

Heino siyana kwemarudzi ezvinhu zviripo pamusoro kondinendi chete.
