Nws yog qhov ib txwm uas, thaum xav txog lo lus coral, cov duab ntawm cov tsiaj ntawm Great Barrier Reef los rau hauv siab, txij li thaum tsis muaj cov tsiaj no muaj peev xwm tsim cov pob zeb limestone exoskeletons, cov pob zeb, qhov tseem ceeb rau lub neej hauv dej hiav txwv, yuav tsis muaj nyob. muaj ob peb hom corals, suav nrog hom mos corals.

Nws yog hydrozoans uas tsim cov pob zeb limestone, hu ua hluav taws corals vim tias lawv cov tom yog txaus ntshai thiab lawv yog ib feem ntawm cov coral reefsmuaj.
Muaj ntau hom marine corals, thiab txog 6,000 hom. Nws yog qhov ua tau los nrhiav cov tawv tawv tawv, uas yog cov uas muaj cov pob zeb uas muaj calcareous exoskeleton, thaum lwm tus muaj lub cev pob txha hloov pauv tau, thiab lwm tus tsis txawm tsim lub cev pob txha hauv lawv tus kheej, tab sis muaj cov ntsia hlau sib txuas hauv cov tawv nqaij, uas tiv thaiv lawv . Ntau corals nyob hauv kev sib raug zoo nrog zooxanthellae (symbiotic photosynthetic algae) uas muab rau lawv nrog feem ntau ntawm lawv cov zaub mov.
Ib txhia ntawm cov tsiaj no nyob hauv loj colonies, thiab lwm tus hauv txoj kev nyob ib leeg. Lawv muaj cov tsev pheeb suab nyob ib puag ncig lawv lub qhov ncauj uas tso cai rau lawv ntes cov zaub mov uas ntab hauv dej. Zoo li lub plab, lawv muaj kab noj hniav nrog a cov ntaub so ntswg hu ua gastrodermis, uas tuaj yeem septate lossis nrog nematocysts (stinging cells zoo li jellyfish) thiab pharynx uas sib txuas lus nrog lub plab.
Ntau hom tsiaj coral tsim lub reefs, lawv yog symbiosis nrog zooxanthellae, hu ua hermatypic corals. Corals uas tsis tsim cov reefs yog ntawm hom ahermatypic. Nov yog kev faib tawm uas siv los paub ntau hom corals. Corals tuaj yeem rov tsim dua asexually siv ntau lub tswv yim, tab sis lawv kuj ua tiav kev sib deev.
Dab tsi yog txoj haujlwm ntawm corals?

Tsis tas li ntawd, lawv nyob hauv tsev rau ntau hom tsiaj txhu, ntses thiab molluscs. yog hauv qab kev pheej hmoo ploj vim kev hloov pauv huab cua, muaj kuab paug thiab nuv ntses tsis xwm yeem.
Hermatypic corals: piav qhia thiab piv txwv
Koj hermatypic corals yog hom tawv corals uas muaj pob zeb exoskeleton tsim los ntawm calcium carbonate. Hom coral no yog txaus ntshai los ntawm kev hu ua "coral bleaching". Cov xim ntawm cov corals no yog los ntawm kev sib raug zoo nrog cov zooxanthellae.
Cov microalgae, lub hauv paus tseem ceeb ntawm lub zog rau corals, tau raug kev hem thawj los ntawm kev nce qhov kub hauv hiav txwv vim yog los ntawm kev hloovhuab cua, tshav ntuj ntau dhau thiab qee yam kab mob. Thaum zooxanthellae tuag, corals dawb thiab tuag, uas yog vim li cas pua pua ntawm coral reefs tau ploj mus. Qee qhov piv txwv ntawm tawv corals yog:
Hom corals: poj niam txiv neej acropora kev los yog mos lwj antler corals:
- Acropora cervicornis;
- Acropora xibtes;
- Acropora proliferates.
Hom corals: poj niam txiv neej Agaricia los yog tiaj corals:
- Agaricia undata;
- Agaricia fragilis;
- Agaricia tenuifolia.
Hom corals: paj hlwb corals, ntawm ntau yam:
- Clivosa Diploria;
- Colpophyllia natans;
- Diploria labyrinthiformis.
Hom corals: Hydrozoa lossis hluav taws corals:
- Millepora alcicornis;
- Stylaster roseus;
- Millepora squarrosa cov.
Ahermatypic corals: piav qhia thiab piv txwv
Lub ntsiab tseem ceeb ntawm ahermatypic coral duab yog lawv tsis muaj pob txha limestone, txawm hais tias lawv tuaj yeem tsim kev sib raug zoo nrog symxiothellae. Yog li ntawd, lawv tsis tsim cov pob zeb coral, txawm li cas los xij, lawv tuaj yeem ua tus kav tebchaws.
Cov cov gorgonians, uas nws lub cev pob txha yog tsim los ntawm cov khoom protein uas zais los ntawm lawv tus kheej. Tsis tas li ntawd, hauv cov nqaij mos yog cov nqaij, uas ua rau muab kev txhawb nqa thiab tiv thaiv.
Hom corals: qee hom Gorgonia
- Ellisella elongata;
- Iridigorgia sp;
- Acanella sp.
Hauv Dej Hiav Txwv Mediterranean thiab Dej Hiav Txwv Atlantic, nws tuaj yeem nrhiav lwm qhov hom mos coral, hauv qhov xwm txheej ntawm subclass Octocorallia, txhais tes ntawm cov neeg tuag (Alcyonium xibtes). Ib qho me me coral uas zaum ntawm cov pob zeb. Lwm yam corals, xws li cov ntawm Capnella genus, muaj kev hloov pauv ntawm tsob ntoo, tawm los ntawm tus taw tseem ceeb.
