Pono i nā mea ola āpau ka ikaika e hoʻokō i kā lākou hana nui, a loaʻa mai nā meaola a lākou e ʻai ai. ʻO ka ʻokoʻa ākea o nā ʻano holoholona e kū nei he mau ʻano like ʻole, a i waena o ia mau mea ke ala a lākou e hānai ai, i loaʻa i kēlā me kēia hui a hana i ka meaʻai ma kekahi ʻano. Pili kēia palapala i kā lākou iho anatomical a me nā kūlana physiological, akā pili pū kekahi i ka nohona a lākou e hoʻomohala ai.
ʻO ia ke kumu i kēia ʻatikala PeritoAnimal e kamaʻilio ai mākou kānana holoholona: nā ʻano a me nā laʻana. E ʻike ʻoe i kēia mau holoholona e hoʻokaʻawale i kā lākou meaʻai mai kahi wai e hoʻomaikaʻi i nā hana kūikawā no kēia kumu. Heluhelu maikaʻi!
He aha nā holoholona kānana
Loaʻa i nā holoholona kānana kēia inoa no kā lākou ʻano hanai hānai. Lawe ʻia ka hānai kānana i nā wahi wai a komo i ka hopu ʻana i nā meaʻai (kahi mea kanu a holoholona paha) a laila hoʻolei i ka wai i hiki ai iā ʻoe ke komo wale i ka mea pio.
He aha nā mea hānai kānana e ʻai ai?
Hiki ke loli a nui ka papaʻai o nā mea hānai kānana a, i kekahi mau ʻano, ʻoi aku kikoʻī, a i haku ʻia i:
- Plankton.
- Nā holoholona ʻē aʻe.
- Mea kanu.
- ʻAmeleka.
- ʻO bacteria
- Noho mau nā meaola.
Nā ʻano holoholona holoholona kānana
Hiki i nā holoholona kānana ke hānai i nā ʻano he nui:
- holoholona hana: ʻo kekahi mau mea hānai kānana e noho mau i ka wai wai, e ʻimi mau nei i ka mea e pono ai.
- holoholona holoholona: hiki iā mākou ke loaʻa i nā ʻano sessile e hilinaʻi ana i nā kahe wai e hele i loko o ko lākou mau kino e hopu i kā lākou meaʻai.
- Nā holoholona e ʻānai i ka wai: i nā hihia ʻē aʻe, kahi i holo ʻole ai nā au i kēia kaʻina hana, lawe nā holoholona i ka wai a me ia ka meaʻai, i mālama ʻia ai e ka holoholona.
Aia kēia ʻano i kekahi mau pūʻulu, mai nā manu a me nā māmele i nā ʻano like ʻole nā holoholona invertebrate wai. He kuleana nui lākou i loko o nā pūnaewele trophic o nā kaiaola. Eia kekahi, hiki iā lākou ke pāʻani i ke kuleana nui i loko ka hoʻomaʻemaʻe wai a me ka hoʻomaʻemaʻe, e like me ke ʻano o nā ʻōlio. E ʻike i ke kikoʻī i kekahi mau laʻana o nā holoholona kānana ma lalo.
Nā laʻana o nā māmela hānai kānana
Ma loko o nā māmala kānana, ʻike mākou i nā mysticite, ʻo ia nā kohola fin, hui kahi i loaʻa ai iā mākou ka mammal nui loa ma ka Honua. ʻAʻole niho o kēia mau holoholona a ma kahi o ko lākou pahi palupalu i hana ʻia me ka keratin, a i kapa ʻia hoʻi nā fins a aia ma ka iwi ā luna. No laila, ke ʻauʻau ʻana, hāmama ka kohola i kona waha no ka wai e komo ai. A laila, me ke kōkua o ke alelo, kipaku ʻo ia i ka wai, a paʻa nā tusks o ka nui kūpono i loko o nā ʻōpae a ʻai ʻia.
Pau kēia hui holoholona iʻa, krill a i ʻole zooplankton, ʻoiai he poʻe kino holoholona lākou, akā ʻo kēlā me kēia meaʻai, pono ia i kahi nui no lākou e hoihoi i ka hopu ʻana iā ia. Hiki i nā koholā ke hānai i nā hohonu like ʻole, ma ka papa kai a ma ka papa.
ʻO kekahi mau laʻana o nā māmela hānai kānana i:
- Pohola Kākau Hema (Eubalaena Australis).
- ʻO koholā Blue (ʻO Musenoptera musculus).
- kohola hina (Eschrichtius robustus).
- kohola pygmy kūpono (Caperea marata).
- Whale I know (Balaenoptera borealis).
Nā laʻana o nā manu kānana
Ma waena o nā manu, ʻike mākou i kekahi i hānai ʻia e ka kānana. ʻO ke kikoʻī, he poʻe lākou e noho nei i ka hapa nui o ka manawa i nā kino o ka wai, a ʻo kekahi o lākou hiki ke lilo i kaʻauʻau maikaʻi loa. Hiki iā lākou ke:
- Kānana manu ʻokoʻa: e like me ka hihia me nā flamingo.
- Manu me ka hānai hui: hiki i nā poʻe ʻē aʻe ke hoʻohui i kēia ʻano hānai me nā hoʻolālā adaptive ʻē aʻe, e like me nā pēpē, i loaʻa nā ʻano kānana, akā loaʻa pū kekahi ʻano "niho" liʻiliʻi i loko o ko lākou nuku, kahi e hiki ai iā lākou ke hoʻopaʻa pono i ka mea pio.
Ma waena o nā meaʻai a kēia mau manu e kānana ai, hiki iā mākou ke ʻike i ka ʻōpae, molluscs, nā larvae, nā iʻa, nā limu a me nā protozoa. I kekahi mau hihia, komo paha lākou nā ʻiliʻili liʻiliʻi e hoʻopau i kekahi mau koʻohune i loaʻa i kēia sediment.
Nā laʻana o ka iʻa kānana
I ka iʻa pūʻulu aia kekahi mau ʻano he mau mea hānai kānana, a ʻo kā lākou papaʻai hiki ke komo i ka plankton, nā crustacea liʻiliʻi, nā iʻa liʻiliʻi ʻē aʻe a, i kekahi mau manawa, algae. Ma waena o nā iʻa kānana, ʻike mākou, no ka laʻana:
- Mano kohola (rhincodon typus).
- manō ʻelepani (cetorhinus maximus).
- Mano o Greatmouth (Nā pelagios Megachasma).
- menhaden (Brevoortia tyrannus).
ʻO ka maʻamau, ʻae kēia mau holoholona i ka wai e komo i ka waha a hele i nā aʻa, kahi ma laila hanana ʻōniu paʻa kēlā i ka meaʻai. Ma hope o ka kipaku ʻia ʻana o ka wai, hoʻomaka lākou e hoʻopau i ka meaʻai.
Nā laʻana o ka kānana invertebrates
Ma loko o nā invertebrates, ʻike mākou i ka mea ʻokoʻa loa o nā holoholona hānai kānana, a e like hoʻi me nā mea hānai hānai kānana, he wai wale nō lākou. E nānā i nā hiʻohiʻona o nā ʻano ʻokoʻa o nā kānana invertebrates:
- nā molluscs bivalve: ma loko o kēia pūʻulu ʻike mākou i nā ʻōtio, nā kūpeʻe a me nā scallops. I ka hihia o nā ʻōpihi, omo lākou i ka wai me ka neʻe o ko lākou maka maka, a paʻa ka meaʻai i kahi mea momona a lākou i loko o kā lākou jowls. Kuhi nā ʻōpili i nā mea haumia like ʻole i hiki i ka wai, e hana ana iā lākou i mea e makaʻu ʻole ai lākou. ʻO nā mussels hoʻi, hānai i ka phytoplankton a kau ʻia nā meaola, e hoʻohana pū ana hoʻi i ka cilia e kahe ai ka wai kai i loko o ko lākou mau kino.
- ʻōpala: ke kānana nei nā porifers i nā invertebrates i loaʻa kahi ʻōnaehana o ke kino i kūpono no kēia kaʻina hana, me nā keʻena he nui me ka flagella e mālama i nā meaolaolaola, bacteria, protozoa a me plankton i ka nui, e hānai. Hiki i kēia hui ke mālama i nā mea haumia i loko o ka wai.
- ʻO Crustaceans: ʻElua mau lālā o kēia pūʻulu e hōʻike pono ana i nā mea hānai kānana maikaʻi loa ʻo krill a me MySids, mai nā wahi kai. ʻOiai ko lākou nui liʻiliʻi, kūpono lākou i ka hoʻokō ʻana i ke kaʻina hana o ka kānana a hōʻiliʻili ʻana i nā mea i kāpae ʻia a i ʻole nā fitoplankton a lākou e hānai ai. Hana ʻia ka kānana ma o nā hale i kapa ʻia ʻo "ʻeke ʻai", kahi e mālama ʻia ai ka meaʻai no ka ʻai hope.
Loaʻa i nā holoholona kānana a kūlana ecological koʻikoʻi i loko o nā kaiaolaola kai, as e hoʻohou i ka wai ma o kāna kaʻina hana kānana, no laila e mālama ana i nā nui o nā hunaahi i kāpae ʻia i kēia hale waena. I kēia ala, lilo kou alo i mea nui i loko o kēia mau ākea. Eia kekahi, e like me kā mākou i ʻōlelo ai, pili nui lākou i ka lālani meaʻai kai, ʻoiai ʻo lākou kekahi o nā pae mua o kēia mau pūnaewele paʻakikī.
Inā makemake ʻoe e heluhelu hou aku i nā ʻatikala e like me Kānana i nā holoholona: nā ʻano a me nā laʻana, Paipai mākou iā ʻoe e komo i kā mākou Maʻī kaulike ʻaoʻao.
