Qhov sib txawv tseem ceeb ntawm Sarcopterygii thiab Actinopterygii yog tias sarcopterygii yog ib chav kawm ntawm cov ntses pob txha, muaj cov ntses lobed uas muaj nqaij, lobed thiab khub fins. Lub caij no, actinopterygii yog ib chav kawm ntawm cov ntses pob txha, muaj cov ntses ray-finned uas muaj fins txhawb nqa los ntawm horny spines.
Ntses uas yog pab pawg osteichthyan yog vertebrates. Lawv cov fins thiab lub cev qauv yuav txawv nyob ntawm seb cov pab pawg twg. Sarcopterygii thiab actinopterygii yog ob chav kawm ntawm osteichthyans. Sarcopterygii ntses yog lobed finned ntses thaum actinopterygii ntses yog ray-finned ntses. Feem ntau cov tsiaj nyob rau hauv sarcopterygii yog ploj mus nyob rau hauv kev sib piv rau cov tsiaj nyob rau hauv actinopterygii.
Sarcopterygii yog dab tsi?
Sarcopterygii yog ib pawg ntawm cov ntses pob txha uas muaj cov ntses lobe-finned. Lawv koom nrog pab pawg ntawm Osteichthyan. Sarcopterygii pawg muaj ob hom: coelacanths thiab lungfish. Hom sarcopterygii yog nqaij ntses. Lawv tau ua khub dorsal fins, thiab lub cev koom nrog ib leeg pob txha. Cov nplai ntawm cov sarcopterygians yog cov scaloids tiag tiag, thiab lawv muaj cov pob txha lamellar. Lawv kuj yog tetrapod libs.
Daim duab 01: Sarcopterygii
Ntau tus sarcopterygians muaj tus Tsov tus tw thiab cov hniav uas muaj tseeb enamel. Cov hom ntawm sarcopterygii feem ntau yog cov tsiaj uas ploj lawm. Lawv feem ntau pom nyob rau sab hnub poob Indian Oceans.
Actinopterygii yog dab tsi?
Actinopertygii yog tus thib ob loj pab pawg tswv cuab ntawm Osteichthyans. Lawv tseem hu ua ray-finned ntses vim muaj cov pob txha lossis horny spines hauv lawv daim tawv nqaij. Cov actinopterygian fins yog txuas ncaj qha mus rau cov ntsiab lus ntawm lub cev. Lawv tseem hu ua basal skeletal element. Lawv yog cov vertebrates. Thiab, pawg no suav nrog txog 30,000 hom ntses. Kev faib ntawm cov ntses no txawv nyob rau hauv ob qho tib si marine thiab dej tshiab.
Daim duab 02: Actinopterygii
Cov hom nplai tam sim no hauv actinopterygii sib txawv, tsis zoo li hauv sarcopterygii. Lawv txhua tus muaj nyob rau hauv pawg teleosts. Lawv muaj cov pob txha pob txha, thiab sab hauv yog tsim los ntawm cov ntaub so ntswg fibrous.
Kev yug me nyuam ntawm cov ntses ray-finned tej zaum yuav qhia cov qauv nyuaj. Hauv ntau hom, cov poj niam sib deev raug cais. Lawv undergo lwm fertilization. Cov hom ntawm actinopterygii muaj lub sijhawm ua luam dej dawb. Txawm li cas los xij, hauv qee hom, muaj kev hloov ntawm kev sib deev uas lub voj voog pib ua poj niam thiab xaus li txiv neej. Qee hom kuj muaj peev xwm ua rau nws tus kheej - fertilizing.
Dab tsi yog qhov zoo sib xws ntawm Sarcopterygii thiab Actinopterygii?
- Sarcopterygii thiab Actinopterygii yog ob chav kawm ntawm cov ntses pob txha.
- Ob leeg yog vertebrates thiab chordates thiab yog dej nyob rau hauv xwm.
- Lawv koom nrog pab pawg osteichthyas, yog li lawv cov poj koob yawm txwv kawg yog Osteichthyes.
- Lawv muaj peb lub siab.
- Ntxiv mus, ob chav kawm no muaj cov qauv fin.
- Lawv muaj zais zis ua luam dej.
Qhov txawv ntawm Sarcopterygii thiab Actinopterygii yog dab tsi?
Sarcopterygii thiab actinopterygii yog ob pawg ntawm osteichthyans. Qhov sib txawv tseem ceeb ntawm sarcopterygii thiab actinopterygii tsuas yog nyob ntawm lawv cov qauv fin. Sarcopterygii ntses hom muaj lobed fins, thaum cov ntses actinopterygii muaj ray fins.
Ntxiv mus, tus nqi ntawm extinction hauv sarcopterygii yog siab dua piv rau actinopterygii. Yog li, qhov no yog lwm qhov sib txawv tseem ceeb ntawm sarcopterygii thiab actinopterygii. Tsis tas li ntawd, cov nplais muaj nyob hauv ob hom kuj sib txawv; ntses actinopterygii muaj horny spines thaum sarcopterygii ntses tsis muaj horny spines.
Summary – Sarcopterygii vs Actinopterygii
Sarcopterygii thiab actinopterygii yog ob pawg loj ntawm osteichthyans, uas suav nrog vertebrate bony ntses. Feem ntau ntawm cov hom no yog marine. Sarcopterygii yog cov kab mob uas ploj lawm uas muaj ob lub lobed fins. Actinopterygii, nyob rau hauv sib piv, muaj ib tug khub ntawm ray fins. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm sarcopterygii thiab actinopterygii. Tsis tas li ntawd, hom sarcopterygii tsis muaj horny spines nyob rau hauv daim tawv nqaij, thaum, lub horny spin muaj nyob rau hauv hom actinopterygii.
