Qhov sib txawv tseem ceeb ntawm tetrapods thiab amphibians yog tias tetrapods yog vertebrates nrog plaub ceg tawv thaum amphibians yog ib pab pawg chordates uas nyob hauv ob qho tib si hauv dej thiab thaj av.
Ib txhia amphibians yog tetrapods; Qee cov tsiaj reptiles kuj poob rau hauv thaj tsam ntawm tetrapods, tab sis tsis yog txhua tus tsiaj reptiles lossis amphibians tuaj yeem raug cais ua tetrapods. Kev nkag siab zoo ntawm qhov sib txawv ntawm tetrapods thiab amphibians yuav ua rau txoj hauv kev los txheeb xyuas ob hom no zoo.
Tetrapods yog dab tsi?
Tetrapods feem ntau yog vertebrates nrog plaub ceg. Ntau cov tsiaj reptiles, ntau amphibians, tag nrho cov tsiaj txhu, thiab tag nrho cov noog poob rau hauv pab pawg no. Qhov no txhais tau tias feem ntau cov vertebrates yog tetrapods, tab sis tsis yog tag nrho. Tetrapods pib hloov zuj zus hauv ntiaj teb ua ntej 400 lab xyoo txij hnub no.
Daim duab 01: Tetrapods
Raws li cov kev xav ntawm kev hloov pauv ntawm tetrapods piav qhia, tetrapods ntxov tshaj plaws yog Panderichthys (ib hom tsiaj muaj tsiaj hauv dej), Ichthyostega thiab Tiktaalik. Txij ntawd los, thaj av nyob amphibians thiab cov tsiaj reptiles tau hloov zuj zus mus rau tsiaj txhu. Txawm li cas los xij, tetrapods muaj ob lub forelimbs hu ua ob txhais tes thiab ob sab nraub qaum hu ua ob txhais ceg. Tsuas yog hauv primates, tag nrho plaub ceg ceg pab taug kev. Tsis tas li ntawd, lawv tau tsim lub ntsws, padded lossis hoofed taw, pob ntseg thiab qhov ntswg, pluab lossis plaub thiab cov tawv nqaij keratinized raws li kev hloov pauv rau lub neej hauv av. Txawm li cas los xij, qee cov tsiaj txiav txim siab rov qab mus rau dej (whale, ntses taub ntswg ntev, penguin). Ntawm cov amphibians thiab cov tsiaj reptiles uas tsis muaj ceg tawv, qee qhov tseem muaj cov ceg tawv; python yog ib qho piv txwv ntawm qhov no.
Amphibians yog dab tsi?
Amphibians hloov zuj zus los ntawm ntses, ua ntej 400 lab xyoo txij hnub no. Tam sim no, muaj ntau dua 6,500 hom tsiaj nyob hauv lub ntiaj teb, thiab lawv tau faib thoob plaws txhua lub tebchaws. Amphibians tuaj yeem nyob hauv ob qho tib si hauv dej thiab hauv av, tab sis feem ntau ntawm lawv mus rau hauv dej los ua phooj ywg thiab tso lawv cov qe. Feem ntau, amphibian hatchlings pib lawv lub neej nyob rau hauv dej thiab tsiv mus nyob rau hauv av, yog hais tias nws yog ib tug terrestrial hom. Qhov ntawd txhais tau tias, lawv siv tsawg kawg ib theem ntawm lawv lub neej voj voog hauv dej. Thaum lub sij hawm lawv lub neej hauv dej ua larva lossis tadpole, amphibians coj cov ntses me me. Tadpoles tau txais cov txheej txheem ntawm metamorphosis los ntawm larvae mus rau cov neeg laus.
Daim duab 02: Amphibians
Amphibians muaj lub ntsws rau cua ua pa ntxiv rau lawv cov tawv nqaij, qhov ncauj kab noj hniav, thiab / lossis gills. Amphibians yog peb lub cev cov ntaub ntawv xws li anurans, caudate thiab gymnophions. Anurans muaj lub cev zoo li Qav. Qav thiab toads yog piv txwv ntawm anurans. Caudates muaj tus Tsov tus tw. Salamanders thiab Newts yog cov piv txwv ntawm caudates. Gymnophions tsis muaj ceg tawv (Caecilians). Yog li ntawd, tsuas yog rau caecilians, tag nrho lwm yam amphibians yog tetrapods. Lawv tsis muaj nplai ntawm lawv cov tawv nqaij. Tab sis lawv cov tawv nqaij yog lub npog lub cev moistened uas pab txhawb kev sib pauv roj.
Feem ntau, amphibians tsis tshua pom nyob rau hauv cov huab cua suab puam, tab sis muaj ntau heev nyob rau hauv qhov chaw ntub dej thiab ntub dej. Tsis tas li ntawd, lawv nyob hauv cov dej tshiab tshaj qhov chaw dej ntsev. Txij li thaum lawv yog cov rhiab heev rau ib puag ncig kev hloov pauv, amphibians tseem ceeb ua bioindicators. Txawm li cas los xij, ib puag ncig muaj kuab paug feem ntau cuam tshuam rau amphibians ntau dua li lwm yam kev ua neej.
Dab tsi yog qhov zoo sib xws ntawm Tetrapods thiab Amphibians?
- Tetrapods thiab amphibians suav nrog vertebrates.
- Tetrapods thiab qee qhov amphibians muaj plaub ceg. Yog li ntawd, qee qhov amphibians yog tetrapods.
- Nws ntseeg tias tetrapods tau hloov zuj zus los ntawm amphibians.
Qhov txawv ntawm Tetrapods thiab Amphibians yog dab tsi?
Tetrapods yog plaub-limbed vertebrates thaum amphibians yog ib pab tsiaj uas nyob hauv dej thiab av ib puag ncig. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm tetrapods thiab amphibians. Tetrapods suav nrog ntau hom ntau dua li amphibians. Tsis tas li ntawd, tetrapods yog qhov loj hauv lub cev ntau dua li amphibians. Yog li, cov lus tseeb no tseem qhia qhov txawv ntawm tetrapods thiab amphibians.

Summary – Tetrapods vs Amphibians
