He mea maʻamau ia, ke noʻonoʻo e pili ana i ka huaʻākō, ke kiʻi o nā holoholona o ka Great Barrier Reef i ka noʻonoʻo, ʻoiai me ka ʻole o kēia mau holoholona i hiki ke hana i nā limosico exoskeletons, ʻaʻole nā kai ākea, pono no ke ola i ke kai. aia kekahi mau ʻano o nā koʻa, me nā ʻano ʻākoʻakoʻa palupalu. Akā maopopo iā ʻoe ehia mau ʻano koʻa? I kēia ʻatikala na PeritoAnimal e wehewehe mākou i nā ʻano koʻa a me kekahi mau mea hoihoi e pili ana iā lākou. E hoʻomau i ka heluhelu!
Nā hiʻohiʻona o nā pākako
Na ka ʻākoʻako nā phylum Cnidaria, e like me ka jellyfish. Hoʻokaʻawale ʻia ka hapa nui o nā koʻa i ka papa Anthozoa, ʻoiai aia kekahi ma ka papa Hydrozoa. ʻO ia nā hydrozoans nāna e hoʻoulu i kahi iwi limestone, i kapa ʻia nā ʻākoʻako ahi no ka mea weliweli kā lākou nahu a he ʻāpana lākou o ka ʻākoʻakoʻama laila.
Nui a lehulehu ʻano o nā koʻa kai, a ma kahi o 6,000 mau ʻano. Hiki ke loaʻa nā ʻano ʻākoʻako paʻakikī, ʻo ia nā mea i loaʻa i ka exoskeleton calcareous, ʻoiai he ʻiwi iwi ʻē aʻe ko nā mea ʻē aʻe, a ʻo nā mea ʻē aʻe ʻaʻole lākou i hana i kahi iwi iwi i loko o lākou iho, akā he mau koʻi i hoʻokomo ʻia i loko o kaʻiʻo dermal, e pale ai iā lākou . Noho nā coral he nui i nā simbiosis me zooxanthellae (limu photosynthetic symbiotic) e hāʻawi iā lākou i ka hapa nui o kā lākou meaʻai.
Noho kekahi o kēia mau holoholona nā kolone nui, a me nā mea ʻē aʻe i kahi ala mehameha. Loaʻa iā lākou nā tentacles a puni ko lākou waha e ʻae iā lākou e hopu i nā meaʻai e lana ana i ka wai. E like me ka ʻōpū, loaʻa iā lākou ka lua me ka nāʻiʻo i kapa ʻia ʻo gastrodermis, ka mea hiki ke septate a i ʻole me nā nematocysts (stinging cells like jellyfish) a me kahi pharynx e kamaʻilio pū me ka ʻōpū.
ʻO nā ʻano koʻa he nui, he symbiosis lākou me ka zooxanthellae, i ʻike ʻia ʻo nā coral hermatypic. ʻO nā ʻākoʻakeʻa i hana ʻole i nā koʻa o ka ahermatypic. ʻO kēia ka hoʻohālikelike i hoʻohana ʻia e ʻike ai i nā ʻano koʻa ʻokoʻa. Hiki i nā Corals ke kope asexually me ka hoʻohana ʻana i nā ʻano hana like ʻole, akā lawe pū lākou i ka hānau kolohe.
He aha ka hana o nā ʻākako?
He hana nui ko ka corals ʻoiai he kaiaolaola me ke ola nui. Ma loko o nā hana o nā ʻākoʻako ka kānana ʻana o ka wai no ka hana ʻana i kā lākou meaʻai ponoʻī, a he puʻuhonua ia no ka meaʻai o ka nui o nā iʻa. Eia kekahi, he home lākou no kekahi mau ʻano crustacea, iʻa a mollusc. aia ma lalo pilikia hoʻoweliweli ma muli o ke aniau, ka hoʻohaumia a me ka lawaiʻa kaulike ʻole.
ʻO nā coral Hermatypic: wehewehe a me nā laʻana
ʻO ʻoe ʻākoʻako hermatypic ʻo ia nō nā ʻano ʻākoʻako paʻakikī i loaʻa ka exoskeleton pōhaku i hana ʻia e ka calcium carbonate. ʻO kēia ʻano koʻa hoʻoweliweli ʻino e ka mea i kapa ʻia ʻo "coral bleaching". ʻO ke kala o kēia mau koʻa mai ka pilina symbiotic me zooxanthellae.
ʻO kēia mau microalgae, ke kumu nui o ka ikehu no nā ʻākoʻako, ke hoʻoweliweli ʻia nei e ka piʻi ʻana o ka mahana ma nā moana ma muli o nā hoʻololianiau, nui loa ka lā a me kekahi mau maʻi. I ka make ʻana o zooxanthellae, hoʻoheheʻe nā kōkō a make, ʻo ia ke kumu i nalowale ai he mau haneli mau koʻa. ʻO kekahi mau laʻana o nā ʻākoʻakoʻa paʻakikī:
Nā ʻano o nā koʻa: ke kāne akopora a i nā ʻākoʻakoe dia.
- Acropora cervicornis;
- Acropora palmata;
- Hoʻonui ʻo Acropora.
Nā ʻano o nā koʻa: ke kāne ʻO Agaricia a i nā ʻākoʻakoʻa pālahalaha:
- Agaricia undata;
- Agaricia fragilis;
- ʻO Agaricia tenuifolia.
Nā ʻano ʻākoʻako: nā koʻa lolo, o nā ʻano like ʻole:
- Clivosa Diploria;
- ʻO Colpophyllia natans;
- ʻO Diploria labyrinthiformis.
Nā ʻano ʻākoʻakoʻa: Hydrozoa a i ʻole nā ʻākā ahi:
- Millepora alcicornis;
- Stylaster roseus;
- Millepora squarrosa.
ʻO nā coral Ahermatypic: ka wehewehe a me nā laʻana
ʻO ka hiʻohiʻona nui o ʻākoakoa ahermatypic ʻo lākou anei ʻaʻohe ou iwi kapala, ʻoiai hiki iā lākou ke hoʻokumu i kahi pilina symbiotic me zooxanthellae. No laila, ʻaʻole lākou e hana i nā koʻa kai, akā, hiki iā lākou ke kolone.
ʻO ka poʻe gorgonians, nona ka iwi iwi i hana ʻia e kahi mea protein i huna ʻia e lākou iho. Hoʻohui ʻia, aia i loko o ka ʻiʻo kiko nā spicules, kahi e hāʻawi ai i ke kākoʻo a me ka pale.
Nā ʻano o nā koʻa: kekahi ʻano o Gorgonia
- Ellisella elongata;
- Iridigorgia sp;
- ʻO Acanella sp.
I ke Kai Kaiwaenahonua a me ka Moana ʻAkelanika, hiki ke loaʻa i kekahi ʻē aʻe ʻano ʻākoʻakoʻa palupalu, i kēia hihia o ka subclass Octocorallia, ka lima o ka poʻe i make (Alcyonium palmatum). ʻO kahi ʻākako liʻiliʻi palupalu e noho ana ma luna o nā pōhaku. ʻO nā corals palupalu ʻē aʻe, e like me nā ʻano o ka genus Capnella, loaʻa i kahi kūlike arboreal, e lālā ana mai ka wāwae nui.
Inā makemake ʻoe e heluhelu hou aku i nā ʻatikala e like me Nā ʻano o nā koʻa: nā ʻano a me nā laʻana, Paipai mākou iā ʻoe e komo i kā mākou Curiosities ʻāpana o ka honua holoholona.
