Qhov sib txawv tseem ceeb ntawm Mollusca thiab Echinodermata yog nyob ntawm qhov chaw nyob ntawm cov kab mob uas muaj nyob hauv ob chav kawm no. Molluscs nyob rau hauv ob qho tib si hauv av thiab dej ib puag ncig thaum echinoderms nyob nruj me ntsis hauv thaj chaw marine.
Phylum Mollusca thiab Phylum Echinodermata belongs rau Kingdom Animalia. Muaj ib qho nruab nrab ntawm Mollusca thiab Echinodermata nyob rau hauv cov nqe lus ntawm morphological, physiological thiab cwj pwm cwj pwm. Txawm li cas los xij, ob qho tib si molluscs thiab echinoderms yog triploblastic, thiab lawv muaj lub plab zom mov tiav. Biologists thiab taxonomists kawm cov yam ntxwv ntawm cov kab mob ntawm txhua tus phylum txhawm rau txhawm rau txheeb xyuas cov kab mob zoo.
Mollusca yog dab tsi?
Phylum Mollusca belongs rau lub Nceeg Vaj Animalia thiab suav nrog ob sab symmetrical kab mob uas yog triploblastic hauv xwm. Molluscs nyob hauv ob qho tib si terrestrial thiab dej ib puag ncig. Cov kab mob uas muaj nyob rau hauv phylum Mollusca qhia txawv segmentation. Lawv lub cev muaj peb ntu sib txawv: lub taub hau, visceral loj thiab ventral ko taw. Ntxiv mus, ventral ko taw pab nyob rau hauv locomotion.
Ib txheej txheej nyuaj lossis lub plhaub npog sab hauv ntawm cov molluscs. Lub plhaub yog tsim los ntawm cov khoom siv calcareous. Tsis tas li ntawd, lub cev kab noj hniav ntawm molluscs yog hemocoel thiab cov ntshav ncig thoob plaws hauv lub cev ntawm qhov hemocoel.
Daim duab 01: Mollusca
Molluscs qhia ua tiav lub koom haum. Lawv muaj ib tug ua tiav digestive ib ntsuj av uas muaj ib tug radula qauv rau pub. Lub paj hlwb muaj ib tug khub ganglia thiab txuas cov hlab ntsha. Tsis tas li ntawd, molluscs muaj qhov qhib circulatory system nrog lub plawv thiab aorta. Molluscs respire los ntawm cov qauv tshwj xeeb hauv gills hu ua ctenidia. Lawv kuj muaj metanephridia rau excretion. Tsis tas li ntawd, molluscs yog bisexual tsiaj, thiab lawv fertilization tshwm sim nyob rau hauv los yog sab nraud.
Phylum Mollusca suav nrog rau chav kawm: Bivalvia, Gastropoda, Cephalopoda, Monoplacophora, Amphineura thiab Scaphopoda. Yog li ntawd, phylum Mollusca suav nrog cov kab mob xws li clams, octopus, squid thiab cuttlefish, thiab lwm yam.
Echinodermata yog dab tsi?
Phylum Echinodermata, uas yog lub Nceeg Vaj Animalia, suav nrog triploblastic coelomates. Lawv nyob tsuas yog nyob rau hauv ib puag ncig marine. Tsis tas li ntawd, lawv qhia radial symmetry, tshwj xeeb tshaj yog penta radial symmetry raws li pom nyob rau hauv starfish. Txawm li cas los xij, lawv tsis qhia segmentation. Lawv muaj lub cev tiaj tus, lub hnub qub-puab lossis elongated lub cev. Cov yam ntxwv ntawm echinoderms muaj xws li lub xub ntiag ntawm cov hlab ntaws thiab cov hlab ntsha dej, muaj lub qhov ncauj nyob rau hauv lub ventral sab thiab lub qhov quav nyob rau hauv lub dorsal sab thiab papula rau ua pa.

Cov kab mob no tseem qhia txog lub koom haum raug nrog rau kev zom zaub mov ua tiav. Txawm hais tias lawv tsis muaj lub paj hlwb ua tiav, lawv teb rau stimuli. Tsis tas li ntawd, lawv cov hlab ntsha tau txo qis, thiab cov ntshav tsis muaj xim. Echinoderms yog bisexual, thiab lawv nthuav tawm sab nraud fertilization.
Phylum Echinodermata suav tsib chav kawm xws li Asteroidea, Ophiuroidea, Echinoidea, Holothuroidea thiab Crinoidea. Starfish, hiav txwv urchin, hiav txwv dib yog paub zoo echinoderms.
Dab tsi zoo sib xws ntawm Mollusca thiab Echinodermata?
- Mollusca thiab Echinodermata yog ob phyla ntawm Kingdom Animalia.
- Lawv yog cov kab mob triploblastic.
- Tsis tas li, ob qho tib si qhia txog theem ua tiav ntawm lub koom haum.
Qhov txawv ntawm Mollusca thiab Echinodermata yog dab tsi?
Mollusca thiab Echinodermata yog ob qhov loj ntawm lub nceeg vaj Animalia. Phylum Mollusca suav nrog triploblastic hemocoelomates uas nyob hauv ob qho tib si hauv av thiab hauv dej ib puag ncig thaum phylum Echinodermata suav nrog triploblastic coelomates uas nyob hauv ib puag ncig marine. Yog li, peb tuaj yeem xav txog qhov no yog qhov sib txawv tseem ceeb ntawm Mollusca thiab Echinodermata. Ntxiv mus, qhov sib txawv ntxiv ntawm Mollusca thiab Echinodermata yog tias molluscs muaj hemocoel thaum echinoderms muaj coelom.
Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm Mollusca thiab Echinodermata yog tias cov molluscs muaj lub cev segmented thaum echinoderms tsis qhia segmentation. Tsis tas li ntawd, molluscs qhia ob sab symmetry thaum echinoderms qhia radial symmetry. Qhov no yog qhov sib txawv loj ntawm Mollusca thiab Echinodermata. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm Mollusca thiab Echinodermata yog fertilization. Thaum molluscs qhia ob qho tib si sab hauv thiab sab nraud fertilization, echinoderms qhia tsuas yog sab nraud fertilization.
Cov infographic hauv qab no sawv cev rau cov ntaub ntawv ntxiv txog qhov sib txawv ntawm Mollusca thiab Echinodermata.
Summary – Mollusca vs Echinodermata
Mollusca thiab Echinodermata yog ob lub phyla uas zwm rau Kingdom Animalia. Lawv yog cov kab mob triploblastic. Molluscs muaj hemocoel thaum echinoderms muaj coelom. Qhov sib txawv tseem ceeb ntawm Mollusca thiab Echinodermata yog thaj chaw lawv nyob. Molluscs nyob hauv ob qho tib si terrestrial thiab dej ib puag ncig. Hauv qhov sib piv, echinoderms tsuas yog nyob hauv thaj chaw marine. Lawv qhia txog theem nyuaj ntawm lub koom haum txawm hais tias lawv cov kev hloov pauv txawv raws li ib puag ncig lawv nyob hauv. Clams, oyster thiab squid, yog qee qhov molluscs thaum hiav txwv dib, hnub qub thiab hiav txwv urchin yog qee qhov echinoderms. Yog li, qhov no qhia txog qhov sib txawv ntawm Mollusca thiab Echinodermata.
