KA hana hou mollusc ʻokoʻa ia e like me nā ʻano molluscs like ʻole e kū nei. Hoʻololi nā hoʻolālā reproductive e like me ke ʻano o ka nohona kahi a lākou e noho ai, inā he holoholona ʻāina a wai paha, ʻoiai lākou āpau e hana kolohe.
I kēia ʻatikala PeritoAnimal, wehewehe mākou i ke kikoʻī pehea ka hana kope o molluscs, akā e wehewehe mua i nā molluscs maoli, kekahi o ko lākou ʻano a me nā kikoʻī nui e pili ana i kā lākou ʻōnaehana hānau. Pēlā nō, e kikoʻī mākou i ʻelua mau laʻana o ka hana hou ʻana i nā molluscs e like me nā laha.
He aha nā mollusc? Nā ʻano a me nā laʻana
Hoʻokumu ka Molluscs i kahi phylum nui o nā holoholona invertebrate, aneane like ka nui me nā arthropods. Aia kekahi ʻano like ʻole o nā molluscs, akā hāʻawi like lākou āpau i kekahi mau ʻano e hui pū, ʻoiai he pākahi kā kēlā me kēia. ʻO kēia mau hiʻohiʻona a mākou i ʻōlelo ai i loko o nā mahele o kou kino, i hoʻokaʻawale ʻia ma lalo ʻāpana ʻehā:
- Ekahi Kahi cephalic, kahi e hoʻopili ʻia ai nā mea pono a me ka lolo.
- Ekahi wāwae kūloko muscular loa e kolo. Hoʻololi ʻia kēia wāwae i kekahi mau pūʻulu, e like me nā cephalopods, nona ka wāwae i lilo i mau tentacles.
- Kahi ma hope kahi e loaʻa ai iā mākou ka lua paleal, kahi o nā lālā olpactory, nā gills (i nā molluscs o ke ola wai) a me nā orifices o ke kino e like me ka anus.
- ʻO ka mea hope loa, ke koloka. ʻO ia ka papa dorsal o ke kino, kahi e hūnā i nā hale pale e like me nā kui, nā pūpū a me nā mea make.
Maloko o ʻano o nā mānoanoa, aia kekahi mau papa liʻiliʻi e ʻike ʻia, e like me ka papa Caudofoveata a i ʻole ka papa Solenogastrea. Kuhi ʻia kēia mau molluscs e ka loaʻa ʻana ʻano anuhea a me ke kino pale ʻia e nā kui.
Loaʻa i kekahi molluscs kahi morphology mua loa, e like me ka hihia o nā molluscs no nā papa Monoplacophora a me Polyplacophora. He wāwae muscular ko kēia mau holoholona, e like me nā hika, a pale ʻia ko lākou kino e ka pūpū hoʻokahi, i ka hihia o monoplacophoras, a i ʻole e kekahi, i ka hihia o Polyplacophoras. ʻO nā holoholona i ka hui mua e like me nā ʻōpiʻupuʻu me hoʻokahi kiwikā, a ʻo nā mea o ka lua e like me kahi arthropod kaulana loa, ʻo ka armadillo.
ʻO nā ʻano mollusc ʻē aʻe nā pūpū pio, nā mea, e like me ka inoa e hōʻike nei, loaʻa kā lākou āpau pale ʻia ke kino e ka pūpū i ke ʻano o kahi tusk elephant. No ka papa Scaphopoda kēia mau holoholona, a he kai wale nō.
ʻO nā ʻano mollusc i ʻike nui ʻia ʻo: nā bivalves e like me ka ʻōpae, nā ʻōhi a me nā ʻulu; gastropods e like me nā nīnū a me nā slug; a ʻo ka hopena, ʻo nā cephalopods, ʻo ia ka heʻe, sepia, ka heʻe a me ka nautilus.
Inā makemake ʻoe e komo hohonu i loko o ka honua o nā iʻa, mai haʻalele i kā mākou ʻatikala e pili ana i nā ʻano ʻio.
ʻO ka hana hou ʻana i nā molluscs
I loko o kahi ʻano heterogeneous o nā holoholona i, eia kekahi, hiki ke noho i nā ʻano nohona ʻokoʻa loa, ka hana hou mollusc ʻokoʻa loa ia a ʻano ʻokoʻa e like me ka ʻano o ka mollusk.
Hoʻopuka hou nā molluscs ma o ka hoʻoipoipo kolohe, ʻo ia hoʻi, i loko o kēlā me kēia ʻano he unisexual kanaka, wahine a kāne paha molluscs. Eia nō naʻe, kekahi mau ʻano hermaphrodites a ʻoiai ʻaʻole hiki i ka hapanui ke hoʻomomona iā ia iho (no ka mea pono lākou i ke alo o kahi mea ʻē aʻe), hana kekahi mau ʻano, e like me ka hihia me kekahi mau ʻāpana terrestrial.
ʻO ka hapa nui o nā ʻano mollusc he aquatic a, i kēia ʻano, ʻo ka ʻano nui o ka hoʻoulu mea kūwaho. Loaʻa wale kekahi mau ʻano hoʻouluulu kūloko, e like me ka hihia me nā cephalopods. No laila, loaʻa nā molluscs wai i nā mea kūwaho o waho. Hoʻokuʻu nā wahine ʻelua a me nā kāne i kā lākou gametes i ke kaiapuni, momona lākou, hoʻomohala, paina a noho manuahi manuahi a hiki i ka pae makua, kahi i kahi ʻano he sessile a kolo paha, a ʻo kekahi, he ʻauʻau manuahi.
Nā terrestrial molluscs, ʻo ia nā gastropods lung a i ʻole nā kuhū terrestrial, he a ʻōnaehana hānau hou. He kāne kāne kā kēlā me kēia kanaka, akā hiki ke hana hoʻokahi ma ke ʻano he hoʻokahi i ka manawa o ka moekolohe. Hoʻokomo ke kāne i ka sperm ma o ka peni i ka wahine, kahi e momona ai nā hua. A laila e hoʻomoe ka wahine i nā hua momona i kanu ʻia i ka lepo, kahi e ulu ai lākou.
Nā laʻana o ka hana hou ʻana i nā molluscs
ʻO ka helu nui o nā ʻano ʻokoʻa o nā molluscs e hoʻopīpī i ka synthesis o ka wehewehe e pili ana i kā lākou r.hana ʻāhuhu, no laila, e wehewehe mākou i nā hiʻohiʻona ʻelua o ka mollusc hana hou ʻana:
ʻO ka hana hou ʻana i nā molluscs: snail maʻamau (ʻO Helix asperse)
Ke hiki i ʻelua mau kuhū i ke ʻano makua, ua mākaukau lākou e hana ka hana kope o nā nīʻau. I ka wā ma mua, ma mua o ka moekolohe ʻana, ʻaha ʻelua nā ʻāpana ʻelua. Aia kēia kaʻina i kahi o ka neʻe ʻana o ka pōʻai, nā huʻi a me ka hoʻokuʻu hormonal, i hiki ke hala i 12 mau hola.
Ke kokoke loa nā kuhū, ka mea a mākou e ʻike ai ʻo "pana o ke aloha". ʻO kēia mau hale he mau dart-i hoʻouluulu ʻia i ka hone e kū i ka ʻili o ke keʻo a hāpai i ka holomua hānau. Ma hope o ka pā, lawe kekahi o nā kuhū i ka peni mai kāna pores genital a hui aku me ka pore o ka hoa, lawa i hiki iā ia ke waiho i ka sperm.
Ma hope o kekahi mau lā, hoʻolauna ka holoholona momona i kāna wahi cephalic i loko o ka lepo momona a hoʻomoe i kāna mau hua i kahi pūnana liʻiliʻi. Ma hope o kekahi manawa, a haneri ʻōniha e puka mai ka liʻiliʻi mai kēlā pūnana.
ʻO ka hana hou ʻana i nā molluscs: nā ʻōlio
ʻO ka maʻamau, ke hiki mai ke kau mahana a me ka wai kai ʻoi aku i ka 24 ºC, hiki mai ka wā hānau no nā ʻōpua. Hoʻokuʻu kēia mau holoholona i ka wai i kekahi mau pheromones e hōʻike ana i ko lākou kūlana hānau. Ke hiki mai kēia, ʻo nā ʻōtike wahine a kāne hoʻi hoʻokuʻu i nā miliona o nā gametes e hoʻomomona ʻia ia ma waho o ko lākou kino.
He wikiwiki loa ka hoʻomohala ʻana i nā hua manu a i loko o kekahi mau hola komo lākou i ka pae larval. I kekahi mau pule ma hope, hāʻule lākou i lalo o ka pōhaku, alakaʻi pinepine ʻia e nā hōʻailona kemika mai nā ʻōpua makua ʻē aʻe. kēia mau larvae hui pū me ka substrate e hoʻohana ana i ka sima a lākou e hana ai a e hoʻolilo i ke koena o ko lākou ola ma laila.
Inā makemake ʻoe e heluhelu hou aku i nā ʻatikala e like me ʻO ka hana hou ʻana i nā molluscs: wehewehe a me nā laʻana, Paipai mākou iā ʻoe e komo i kā mākou Curiosities ʻāpana o ka honua holoholona.
