Sei dzvinyu ganda usingagoni kufema? dzvinyu ganda. Features madzvinyu

Dzvinyu - munhu pasi-yakavakirwa mhuka ine utsinye ane muviri ari dzakashandisa nepanyika mararamiro. Iye anogara mumasango, steppes, mumarenje, nemakomo. A muviri duku mutete externally yakafukidzwa vakawanda madzvinyu horny zviyero, kungovimba pulmonary afemeruke. Inofamba tichibatsirwa iri pamusoro pasi muswe uye muviri (groveling) tsoka. Sei dzvinyu ganda usingagoni kufema? Pindura mubvunzo uyu zvichabatsira kudzidza STRUCTURAL zvinhu uye mararamiro imwe hwokufananidzira vamiririri mukirasi nezvinokambaira.

dzvinyu nimble

Zvizere zuva, uswa uye manyoro pamusoro inodziya mabwe panowanikwa chakanaka mhuka duku. Izvi nimble uye chakajairika nedzvinyu. Kureba inondo muviri rinosvika 15-20 masendimita (kusanganisira muswe). Makara - a greenish mashava pamwe mavara matema kuti hukuru siyana. Rokunze rukoko ndiyo yakasimba yakaoma ganda - thickened cornified muchimiro flakes rose muviri uye ichibhabhamisa mumusoro. Nyore avo nenzara, ivo negoroodyo sezvarinonamatira nemakwati miti, matombo kuti kukwira pamusoro. Scaled pabutiro inodzivirira muviri kubva kupwa panze uye kukuvadza. Mhepo hazvirevi pinda nemazviri, ndokusaka dzvinyu havagoni kufema, vanonakidzwa chete ganda chiedza. Ivo kupa muviri pamwe okisijeni, iyo inodiwa masero muviri simba. Panguva anodziya mwedzi, negoroodyo anoteura kakati. Scale kunodzivisa kukura mhuka, zvisinei kuti stratum corneum akasvuura kure uye makwapa akasvibirika itsva.

The nemamiriro dzvinyu

Mutumbi dzinokanganisa nedzvinyu kazhinji neVadzidzi pasi. Bato iri akapa nzira zita mukirasi mhuka - nezvinokambaira, kana nezvinokambaira. boka iri zvinosanganisira yokuzviparadzanisa pamusoro scaly, suborder pamusoro madzvinyu. Vamiririri dzakawanda dzinowanikwa zvinhu kubvumira chokubatanidza muvira rimwe boka. Funga kwokunze nemamiriro dzvinyu:

• muviri ine musoro, muviri, refu muswe, makumbo mana;
• pointy pamberi hofisi musoro runoita mugomba pfupi gobvu mutsipa;
• Meso akadzivirira okumusoro mafungiro ameso, ivo nokupfunha nguva dzose nokuda translucent nictitating Kamudzira - remakore rechitatu;
• mumusoro, peya ari pamhino, kuburikidza icho mhepo inopfuura;
• chokunze Panovhurwa auditory nhengo, akafukidza tympanic Kamudzira, riri shure ziso;
• Nhengo havambozivi - rurimi refu, forked pakupera;
• Makumbo akaumbwa mumapoka matatu, netsoka dzake - minwe mashanu, hapana webbing pakati pavo.

Features madzvinyu

Zvinokambaira - zvakaoma vakaronga mhuka munyika, zvimwe izvo dzakashandisa upenyu hwemvura. Pane zvimwewo zvinoratidza kuti uku madzvinyu pamusoro amphibians:

• mutsipa pakati musoro uye muviri;
• hapana swimming membranes pamusoro minwe makumbo pfupi - nenzara;
• ganda rakaoma ane nyanga butiro;
• fungiro rechitatu.

Usiku, negoroodyo avanda burrows that, pasi pamatombo kana stumps, mumatsutso muna vakadzikama latitudes, kufanana matatya dzinorara kwenguva refu. Amphibians gasi Exchange iyi mberi kuburikidza matete nechidzitiro muviri. Sei dzvinyu ganda haigoni kufema, sezvinoita datya? Zvinokambaira vakarasikirwa kukwanisa kuti gasi mukutsinhana kuburikidza ganda iri nedanho shanduka. Zvisinei, muviri nezvinokambaira muviri ndiko nomumugwagwa kwaitora nguva kupfuura shiri. Panguva anodziya mwedzi, mobile egwavava, anovhima nezvavakatapa, kana mamiriro okunze kutonhora anova lethargic, anodya zvishoma.

kufema madzvinyu

Zamu dzvinyu muviri chikamu vari vasiyana nomuzongoza micheto, kudzivirira mwoyo nemapapu muchiwirirana. Mhepo kuburikidza nasal mawindo anopinda nemumuromo mhango, yakaitirwa dokeriro uye trachea, uye ipapo - ari principales. Light dzvinyu zvakafanana kufema masaga datya, asi zvikuru kunzwisisa chivakwa. Kana wokukudza thorax mhepo iri vakanwa, uye aienda - nedzinovengwa kunoitika. kufamba izvi zvaisanganisira intercostal uye abdominal tsandanyama. Mhepo anozadza zvemapapu masero, akaparadzaniswa nevanhu partitions, dzine zvapararira capillaries. Sei dzvinyu ganda haigoni kufema, sezvinoita datya? Amphibians kupfeka nyoro ganda - mamwe kufema nhengo, kunyanya kudiwa panguva kuhwanda. Mushure integument okisijeni kubva mhepo anopinda kweropa maitiro, uye carbon dioxide zvinoenda zvakatipoteredza. reptilian muviri viomak horny zviyero, vane midziyo ropa. Naizvozvo, ganda chinofema negoroodyo chinoshayikwa.

Kugona panoda

muviri dzvinyu kwakaita ndeyokubvisa kana anotanga kushandisa nenzara vakabatirira kuchangotanga unevenness pasi kana kuhukura. The mhuka inogona vanokwira hunde muti, uri matombo materu. Kuwedzera kumhanya kufamba, pane unodzivirira unhani, maererano chaiwo dzinogarisana. Dzimwe anokwanisa kushandura ganda pasi, uye mamwe anotyisa shinyira, scaring kure nezvikara. Hobvu, tsandanyama muswe chinobatsira paaifamba uye anodzivirira pakurwisa. Pane anonakidza pfuma kuti nhaka dzvinyu. Kana stalker akaitema kubva shure uye anobata muswe, nyore Unokanganisa kure uye anopfuurira squirm kwekanguva. The vavashungurudza kungokangaidzwa kufamba ichi, uye negoroodyo anotizira gwenzi kana uswa burrow. Panzvimbo vakarasika anonaya mhuka (pavezve) mumwe muswe itsva, mapfupi uye mukobvu kupfuura okutanga.

suborder pamusoro madzvinyu

Nhengo ichi taxonomic boka anogona kuwanikwa zvose okunze munyika dzine kunze achinaya mvura uye polar mumarenje. Munyika mune zvinopfuura 5900 marudzi, vakabatana mumhuri. By agamidae muri mhando dzvinyu, achitungamirira arboreal kana pano upenyu. Vamwe vanokwanisa Gliding ndege (genus Draco). Mhuri pakukura madzvinyu - Komodo (3 m).

Vamiririri wemhuri chameleons kushandura ruvara muviri wake. Vanhurume vane anotyisa Basilisk anooneka zvikuru nemichinjiziri uye spines pamwe shure kwayo. madzvinyu ava vanoshambira akanaka uye anogona kumhanya pamusoro mvura, akabatirira ayo pechiso nokuda matambudziko webbed tsoka. Zita genus anowana kubva kufanana ngano basilisk chikara. Iguanas - guru vamiririri suborder pakati madzvinyu. Saka, iguanas vanhuwo kureba -. 1.9-2 M Rinoteta zviduku geckos uye Agam akafukidzwa protuberances vakawanda tuduku kuti abatsire adhesion kuti hukawanika siyana, kunyange girazi. In legless madzvinyu zvachose vasisina maoko nemakumbo, asi ivo vakasiyana nyoka chinjwa kukotsira ziso uye pamberi pafudzi nebhanhire iri marangwanda.

Vamiririri zvose mhuri madzvinyu kuratidza kwadzakabva vakakwana chaicho nzvimbo. Kukwana thermoregulation ivo nekure chokwadi kuti uvande dzinochengeterwa kubva hypothermia uye overheating. Kuwira kuhwanda, madzvinyu kutiza kwechando ari kupisa murenje - kuenda upenyu usiku.
