ʻO ʻoe molluscs he pūʻulu nui lākou o nā holoholona invertebrate, aneane like ka nui me nā arthropods. ʻOiai he mau holoholona ʻokoʻa loa lākou, hiki ke ʻike i kekahi mau ʻano e hoʻokaʻawale ʻokoʻa iā lākou. Makemake ʻoe e ʻike hou e pili ana iā lākou?

I kēia ʻatikala na PeritoAnimal, e ʻike kākou i ka ʻano o nā mollusc e kū nei, ko lākou ʻano a me ka hoʻohālikelike ʻana, a e loaʻa iā mākou kahi papa inoa o nā molluscs na ʻoe e ʻike iki i ka ʻokoʻa. E hoʻomau i ka heluhelu!

he aha nā molluscs

nā molluscs nā invertebrates nona ka helu palupalu e like me ka annelids, akā ʻaʻole hoʻokaʻawale ʻia kona kino makua, ʻoiai e pale ʻia kekahi e ka pūpū. ʻO ia ka pūʻulu lehulehu o nā holoholona invertebrate ma hope o nā arthropods. Aia e pili ana 100,000 mau ʻano, nona ka 60,000 mau gastropods. Hoʻohui ʻia, ʻike ʻia kekahi mau ʻano fossil 30,000.

ʻO ka hapa nui o kēia mau holoholona he molluscs. kai kaibenthic, ʻo ia hoʻi, noho lākou i lalo o ke kai. Terrestrial ka hapa nui o nā poʻe ʻē aʻe, e like me nā nīnō. ʻO ka ʻokoʻa nui e kū nei ke ʻano o kēia mau holoholona i koloneʻa i kahi nui o nā ʻano hale like ʻole a no laila aia nā papaʻai āpau i loko o nā ʻano mollusc.

E ʻike pū ma loko o PeritoAnimal ʻo nā ʻano nā koʻa, kai kai a me ka honua.

Nā Molluscs: nā ʻano

He hui like ʻole nā ​​Molluscs, a ʻo ka ʻimi ʻana i nā ʻano i maʻa mau iā lākou āpau he hana paʻakikī. No laila, e hōʻike mākou i nā hiʻohiʻona maʻamau, ʻoiai he nui nā hoʻokoe.

Māhele ʻia ke kino iwi ʻāpana i ʻāpana nui ʻehā:

• ʻahuʻula: ʻo kaʻili o ka kino e hiki ai ke hūnā i ka pale. Kēia pale i ka chitinous a me ke kumuʻiʻo kumu i hana ma hope hana limestone, pako a i ka pūpū. ʻO kekahi mau holoholona i loaʻa ʻole nā ​​pūpū i nā pale kemika.
• wāwae kūloko: ua ciliated, muscular a me nā aʻa mucous. Mai laila mai, puka mai kekahi mau paʻa o nā mākala dorsoventral e lawelawe i ka wāwae o ka wāwae a hoʻopaʻa i ka ʻahu.
• ʻāpana cephalic: i kēia ʻāpana loaʻa iā mākou ka lolo, ka waha a me nā mea ʻike ʻē aʻe.
• ʻūhā paleal: eia kahi o ka osphradia (nā lālā olfactory), nā kino orifices (anus) a me nā gills, i kapa ʻia ʻo ctenids.

ʻ mea hana digestive shellfish loaʻa kekahi mau hiʻohiʻona hiʻohiʻona:

• ʻŌpū: loaʻa kēia mau holoholona i ka digestion extracellular. Koho ʻia nā huna huna e ka digestive gland (hepatopancreas), a ʻo ke koena e hele i loko o ka ʻōpū e hana i ka noho.
• radula: kēia ʻōhua, aia i loko o ka waha, he membrane i ke ʻano o kahi lepe niho, i kākoʻo ʻia e ka odontophore (ka nui o ka paʻa o ka cartilaginous) a neʻe ʻia e ka musculature paʻakikī. ʻO kona helehelena a me kona neʻe ʻana ua like ia me kahi alelo. ʻO nā niho chitinous i haehae ka radula i ka meaʻai. Hāʻule nā ​​niho i kēlā mau makahiki a mae, a hana nā mea hou i ke ʻeke aʻa. ʻAʻole loaʻa nā raden i nā solenogastros he nui, a ʻaʻohe bivalve i loaʻa.

Eia nō naʻe, me ka hoʻohui, kāu ʻōnaehana puni hāmama, ʻo ka puʻuwai wale nō a me nā mea pili kokoke loa he mau moku. Māhele ʻia ka naʻau i ʻelua atria a me ka ventricle. ʻO kēia mau holoholona ʻaʻohe mea excretory hoʻoholo. Loaʻa iā lākou nā metanephrids e laulima me ka puʻuwai, kahi ultrafilter, e hana ana i ka mimi mua e hoʻopili hou ʻia i nā nephrids, a he kuleana pū kekahi no ka hoʻoponopono ʻana i ka nui o ka wai. ʻ ʻōnaehana hānau he ʻelua gonad i mua o ka pericardium. Hoʻoneʻe ʻia nā gametes i ka lua pale pale, hoʻopili pinepine ʻia i nephrids. Hiki i nā molluscs ke dioecious a i ʻole hermaphrodite.

ka hoʻonohonoho ʻana i nā molluscs

Māhele ka mollusc phylum i papa ʻewalu, a he ola nā mea ola āpau. ʻO ka hoʻonohonoho ʻana o nā mollusc:

• Papa Caudofoveata: he molluscs i loko ʻano anuhea. ʻAʻohe o lākou pū, akā uhi ʻia ko lākou mau kino i nā kui calcareous a me aragonitic. Kanu lākou i ka honua i luna i lalo.
• Papa Solenogasters: he mau holoholona like lākou me ka papa ma mua, no laila ua hoʻokomo ʻia ka mōʻaukala i ka hui like. He ʻano ilo nō hoʻi lākou, akā ma kahi o ka kanu ʻana i ke ola, noho manuahi lākou i ke kai, e hānai nei i nā cnidarians. He lāʻau calcareous a aragonitic kēia mau holoholona.
• Papa Monoplacophore: he molluscs kahiko loa. kou kino ʻo uhi ʻia e ka pūpū hoʻokahi, e like me ka hapalua o ka clam, akā he kapuaʻi muscular ko lākou e like me ke kī.
• Papa Polyplacophora: I ka nānā mua ʻana, ʻano like lākou me kekahi ʻano crustacean, e like me ka armadillos-de-māla. Uhi ʻia ke kino o kēia mau molluscs e kahi papa o nā papa i hoʻoikaika ʻia me ka magnetite. Hoʻokumu pū lākou i ka wāwae kolo kolo muscular a me kahi radula.
• Papa Scaphopoda: he kino lōʻihi loa ko kēia mau molluscs, a me ko lākou iwi, e like me ke ʻano o ka pepeiaohao, a ʻo ia ke kumu i kapa ʻia ai lākou pūpū manu. ʻO ia kekahi o nā ʻano kaulana loa o nā mollusc kai.
• Papa Bivalvia: bivalves, e like me ka inoa e hōʻike nei, he molluscs nona Aia ke kino ma waena o ʻelua mau kiwikā a i ʻole nā ​​pūpū. Pili kēia mau kiʻina ʻelua i ka hana a kekahi mau mākala a me nā ligament. ʻO nā ʻano i kaulana loa o nā bollve mollusc he clams, mussels a me nā ʻōsters.
• Papa Gastropoda: gastropods ʻike ʻia nahenahea me nā slug, ʻĀina ʻāina a kai hoʻi. Loaʻa iā lākou kahi cephalic ʻokoʻa maikaʻi, kahi wāwae muscular no ke kolo a ʻauʻau ʻana paha, a me kahi pūpū dorsal. ʻAʻohe paha kēia pūpū i kekahi ʻano.
• Papa Cephalopoda: ka hui cephalopod i haku ʻia o heʻe, sepia, heʻe a me nautilus. ʻOiai ke ʻano o ia mea, hōʻike lākou i nā pūpū. ʻO ka nautilus ka mea maopopo loa, no ka mea he kūwaho ia. Loaʻa i ka Sepia a me ka heʻe kahi pū ʻoi aku a i ʻole nui o loko o loko. ʻO ka pūpū o ka heʻe e aneane vestigial, ʻelua wale nō mau laina limestone lahilahi e waiho ana i loko o kona kino. ʻO kekahi ʻano nui o nā cephalopods, ma kēia papa, ua hoʻololi ʻia ka wāwae muscular i nā mollusc i mau tentacles. Loaʻa ma waena o 8 a ʻoi aku ma mua o 90 mau tentacles, kaukaʻi ʻia i nā ʻano o ka mollusc.

Laʻana Shellfish

I kēia manawa ʻike ʻoe i nā ʻano a me ka hoʻonohonoho ʻana o nā molluscs. A laila, wehewehe mākou e pili ana i kekahi ʻano o nā mānoanoa a me nā laʻana:

1. ʻO Chaetoderma elegans

like me ilo a me ka iwi ʻole, ʻo kēia kekahi o nā ʻano mollusc e pili ana i ka papa Caudofoveata. He mahele kai pāhele kāna i ka Moana Pākīpika. hiki ke loaʻa ma hohonu o 50 mau mika ma mua o 1800 mau mika.

2. Neomenian carinata

A ʻo kekahi ʻē aʻe mollusc vermiform, akā no kēia ʻohana no ka ʻohana Solenogastrea. ʻIke ʻia kēia ʻano molluscs ma kahi pae hohonu ma waena o 10 a 565 mau mika, noho manuahi ana ma ka Moana Atelanika, ma kahakai o Pokukala.

3. ʻO ka moa kai (Chiton articulatus)

ʻO ke kūpikū kai kahi ʻano molluscpolyplacophora hopena i Mekiko. Noho ia i ka papa pōhaku o ka wahi intertidal. He ʻano nui ia, e piʻi aku ana i 7.5 mau kenimika i ka lōʻihi ma waena o nā ʻano mollusc.

4. Antalis vulgaris

He ʻano ia o mollusk scaphopod me ka pūpū a i ʻole ka iwi-ʻano pū. Keʻokeʻo kona kala. Noho i loko nā ʻiliʻili one a lepo pāpaʻu, i nā kaʻe waena. Hiki ke loaʻa kēia mau ʻano mollusc ma ke kahakai ʻo ʻAkelanika a me ke Kaiwaenahonua.

5. ʻO Coquina (Donax trunculus)

ʻO nā Coquinas kekahi ʻano pūpū. O lākou bivalves o ka liʻiliʻi, noho lākou ma kahakai ʻo ʻAkelanika a me ke Kaiwaenahonua. Kaulana nui lākou i nā meaʻai i ke Kaiwaenahonua. Hiki iā lākou ke noho i ka wahi subtidal e pili ana 20 mau mika ka hohonu.

6. ʻO European Flat Oyster (Ostrea edulis)

ʻO nā ʻōlio kekahi o nā ʻano molluscsbivalves o ke kauoha Ostreoid. Hiki i kēia ʻano ke ana i 11 kenimika a hana makuahine o nā momi momi. Hāʻawi ʻia lākou mai Norewai a i Morocco a me ke Kaiwaenahonua. Eia kekahi, ua mahi ʻia lākou i ka loko kai.

E ʻike i kekahi laʻana o nā holoholona vertebrate a invertebrate i kēia ʻatikala PeritoAnimal.

7. Caracoleta (Helix aspersa)

ʻo ke kuhū a anomollusk gastropod me ka hanu hanu, ʻo ia hoʻi, ʻaʻohe ona gills a noho ma ka ʻili o ka honua. Pono lākou i ka nui o ka wai, a inā ʻaʻole lākou, peʻe lākou i loko o kā lākou pū no nā wā lōʻihi e pale ai i ka maloʻo ʻana.

8. ʻO ka heʻe maʻamau

ʻO ka heʻe maʻamau he a cephalopod e noho nei ma ka Moana ʻAkelanika a me ke Kai Waihona. Ana ʻia ma kahi o ka mika ka lōʻihi a hiki ke hoʻololi i ke kala i kāna chromatophores. He waiwai nui kona no ka gastronomy.

Nā ʻano mollusc ʻē aʻe

Makemake ʻoe e ʻike hou? A laila, e haʻi mākou i nā mea ʻē aʻe ʻano laha o nā molluscs:

• Scutopus robustus;
• Scutopus ventrolineatus;
• Laevipilina cachuchensis;
• Laevipilina rolani;

• ʻO Octopus Pākīpika Giant (Enteroctopus dofleini);
• Nautilus belauensis.

E aʻo hou aʻe e pili ana i ka honua holoholona, ​​e nānā i kā mākou ʻatikala e pili ana i nā ʻano scorpion.

Inā makemake ʻoe e heluhelu hou aku i nā ʻatikala e like me Nā ʻano mollusc: nā ʻano a me nā laʻana, Paipai mākou iā ʻoe e komo i kā mākou Curiosities ʻāpana o ka honua holoholona.
