ʻO kēia hui o nā jellyfish, mai ka papa o nā mea kolo, aia ma kahi o 20 mau ʻano. Akā weliweli loa lākou āpau, ʻoiai no nā kānaka.
Ua kapa ʻia kēia mau jellyfish ma muli o ke ʻano o kā lākou dome. Mai lāʻau make jellyfish pahu make he mau kakini. No laila ʻo wai lākou, kēia ʻūlū kai a i ʻole ke kai?
Jellyfish pahu noho
Noho kēia ʻano i nā wai subtropical a me nā kai pāheona me ka salinity moana. I ke kai o nā latitude mahana, ʻelua mau ʻano o kēia mau jellyfish i hoʻopaʻa ʻia. ʻO kahi ʻano liʻiliʻi, ʻo Tripedalia cystophora, e noho ana ma luna o ka wai a ʻau i waena o nā aʻa o nā kumu mangrove ma Jamaica a me Puerto Rico.
ʻO kēia jellyfish kahi jellyfish undemanding e ola maʻalahi a hana hou i ka pio, no laila ua lilo ia i kumuhana o ke aʻo ʻana ma ka Faculty of Biology ma Suedena.
Ua lilo ka wai tropical tropical o Pilipine a me Australia i home jellyfish pahu australia (Chironex fleckeri). Liʻiliʻi, pale ʻia mai ka makani, nā coves me kahi one o lalo kā lākou wahi noho punahele.
I ke anilā mālie, kokoke lākou i nā kahakai, ʻoiai i ke kakahiaka anuanu a ahiahi paha, ʻauʻau lākou kokoke i ka wai. I nā manawa wela o ka lā, poho lākou i ka hohonu anuanu.
Nā hiʻohiʻona o jellyfish pahu
Ke hoʻopaʻapaʻa nei nā kānaka ʻepekema e pili ana i ka pilina o nā jellyfish pahu i kahi kaʻawale kaʻawale a i kahi papa kūʻokoʻa. ʻO ka hui o scyphoid coelenterates pili pū me jellyfish pahu, akā ʻokoʻa kona mau ʻelele ʻē aʻe, loaʻa i nā jellyfish pahu kekahi mau hiʻohiʻona kikoʻī. ʻO ka ʻokoʻa nui ma waho - ke ʻano o ka dome ma ka ʻoki he square a huinahā paha.
Loaʻa i nā jellyfish āpau i nā tentacles stinging i nā kekelē ʻokoʻa, akā ʻoi aku ka jellyfish pahu ma mua o nā mea ʻē aʻe. ʻO kēia ka jellyfish ʻawahia loa, hiki ke pepehi i ke kanaka me kāna mau ʻāpana ʻino.
ʻOiai me kahi pā pōkole, e mau ana ka wela i ke kino, e loaʻa ka ʻehaʻeha a hoʻomaka ka mea i hoʻomake ʻia e ʻū. Me ka pili mau me nā tentacles jellyfish pahu (ʻo kahi laʻana, inā hihia ke kanaka i loko o lākou, a ʻoi aku kekahi ma mua o hoʻokahi nahu) make i loko o 1-2 mau minuke.
I nā kau anuanu, hele mai ka nui o nā jellyfish ʻōpelu i kahakai, a laila lilo nā kānaka he nui he nui iā lākou. ʻAʻole lākou e hoʻolālā e hoʻouka i ke kanaka, i ka ʻaoʻao ʻē, ke hoʻokokoke nā mea like ʻole, ʻauʻau lākou.
ʻO kekahi hiʻohiʻona hiʻohiʻona ʻole o ka jellyfish ka hihiʻo. ʻO nā maka o ka lumi i hoʻomohala maikaʻi ʻia, e like me nā vertebrates, loaʻa i nā ʻōnaehana opio maikaʻi loa. Akā ʻo ka mea nui ka paʻakikī o ka jellyfish e hoʻokaʻawale i nā kikoʻī liʻiliʻi, a ʻike wale i nā mea nui. ʻIke ʻia nā maka ʻeono i nā lua pūpū ma nā ʻaoʻao o ka bele.
ʻO ke ʻano o ka maka e komo pū me ka retina, ke kōā, ke aniani, a me nā iris. Akā, pili ʻole nā maka me ka ʻōnaehana hopohopo o ka jellyfish pahu, no laila ʻaʻole maopopo i ka ʻike.
ʻO ka nohona jellyfish pahu
Ua hōʻike ʻia aia i ka jellyfish pahu kahi ʻano hahai holoholona. Akā ua maopopo i nā ʻepekema ʻē aʻe he passive loa lākou, a ke kali wale nei no ka mea i hōʻino ʻia i loko o ka wai, e hoʻopā ana me kā lākou mau tentacles i "hopu ʻia i ka lima."
Huikau kā lākou hana me ka neʻe maʻamau, i loaʻa iā lākou i kahi ʻoi aku ka nui ma mua o nā laha ʻē aʻe, i kahi kekelē - hiki i ka jellyfish pahu ke ʻau i ka wikiwiki o 6 mika i kēlā me kēia minuke.
Loaʻa ka wikiwiki o ka neʻe e ka jet jet o kahi kahawai ma o ka subumbrellar space ma muli o ka hōʻemi ʻana o nā mākua bele. E hoʻonohonoho ʻia ke ʻaoʻao o ka neʻe e ka asymmetrically aelike vellarium (ka pā o ka lihi bele).
Hoʻohui ʻia, ʻo kekahi o nā ʻano o nā jellyfish pahu he mau kīʻaha kiki kūikawā hiki ke hoʻopaʻa ʻia ma nā wahi paʻa o ka lalo. He phototaxis kekahi mau ʻano, ʻo ia hoʻi hiki iā lākou ke ʻau i ke ala o ke kukui.
He paʻakikī loa ka nānā ʻana i kahi jellyfish pahu makua, no ka mea, ʻaneʻane maopopo loa lākou a hoʻāʻo e ʻauʻau ke hele aku kahi kanaka. Alakaʻi lākou i kahi nohona malū. I nā lā wela e iho i lalo i ka hohonu, a i ka pō piʻi i luna.
ʻOiai he nui ka jellyfish pahu - aia ka dome i 30 cm ke anawaena, a piʻi nā tentacles i 3 mika i ka lōʻihi, ʻaʻole hiki ke ʻike ʻia i ka wai.
Mea ʻai
Ma nā kihi ʻehā o ka dome, aia nā tentacles e kaʻawale ana mai ke kumu. Aia nā epidermis o kēia mau tentacles i nā pūnaewele streak, i hoʻoulu ʻia ma ka hoʻopili ʻana me kekahi mau mea i ka ʻili o nā kānaka ola, a pepehi i ka mea i hōʻino ʻia me kā lākou lāʻau make.
Hoʻopili nā toxins i ka ʻōnaehana, ʻili a me nā mākala puʻuwai. ʻO kēia mau tentacles e hoʻoneʻe i ka mea pio i kahi o ka sumbrellar, kahi e wehe ai ka waha.
Ma hope o kēlā, lawe ka jellyfish i kahi kū i luna a i lalo paha me kona waha a ʻoluʻolu e ʻimi i ka meaʻai. Me ka hana o ke ao, ʻoi aku ka maikaʻi o ka hānai jellyfish pahu i ka pō. ʻO kā lākou meaʻai ka ʻōpae liʻiliʻi, zooplankton, iʻa liʻiliʻi, polychaetes, bristle-mandibular a me nā invertebrates ʻē aʻe.
I ke kiʻi, kahi kuni mai kahi jellyfish pahu
ʻO ka jellyfish pahu kahi loulou nui i ka kaulahao meaʻai o nā kai kahakai. Ua ʻike ʻia ke ʻano o ka hihiʻo i ka wā ʻimi holoholona a hānai ʻana.
ʻO ka hana hou a me ke ola o ke ola
E like me nā jellyfish āpau, hoʻokaʻawale nā jellyfish pahu i ko lākou ola i ʻelua mau kekeke: ʻo ka pae polyp a me ka jellyfish ponoʻī. I ka mua, pili ka polyp i nā substrates lalo, kahi e ola ai ia, e hana kope asexually - e ka ʻōpuʻu.
I ke kaʻina hana o ia ola ʻana, hiki mai ka metamorphosis, a hoʻokaʻawale mālie ka polyp. ʻO kahi ʻāpana nui aʻe e hele i ke ola i loko o ka wai, a make ka ʻāpana i koe ma lalo.
No ka hana kope ʻana i kahi jellyfish pahu, pono ke kāne a me ka wahine, ʻo ia hoʻi, ka hoʻohua ʻana i ka moekolohe. ʻO ka hapanui pinepine o waho. Akā koho kekahi mau ʻano e hana ʻokoʻa. ʻO kahi laʻana, hana nā kāne o Carybdea sivickisi i nā spermatophores (nā ipu me ka sperm) a hāʻawi iā lākou i nā wahine.
Mālama nā wahine iā lākou i loko o ko lākou ʻōpū a hiki i ka wā e pono ai lākou no ka momona. ʻO nā wahine o ka ʻano Carybdea rastoni e loaʻa a kiʻi i ka sperm i hūnā ʻia e nā kāne ponoʻī, me nā mea e momona ai lākou i nā hua.
Mai nā hua manu, hoʻokumu ʻia kahi larva ciliary, kahi e noho ai ma lalo a lilo i polyp. Kapa ʻia ia he pelula. Aia kekahi mau hoʻopaʻapaʻa e pili ana i ka hana hou a me ke ola pōʻaiapuni. Ma kekahi ʻaoʻao, ua unuhi ʻia ka "hānau" o hoʻokahi jellyfish mai hoʻokahi polyp ma ke ʻano he metamorphosis.
Mai laila mai ka polyp a me ka jellyfish i ʻelua mau pae o ke ongeny o hoʻokahi mea. ʻO kahi koho ʻē aʻe ke hoʻokumu ʻia ʻana o kahi jellyfish i ke kaʻina o kahi ʻano o ka hana hou ʻana, kahi i kapa ʻia e nā ʻepekema ʻo stodilation monodisc. Hoʻohālikelike ia i ka strobilation polydisc o polyps i ke kumu o ka jellyfish scyphoid.
ʻO ke ʻano o ka jellyfish pahu e hōʻike i kahi kumu kahiko loa. ʻO nā fossil kahiko loa i loaʻa ma kahi kokoke i ke kūlanakauhale ʻo Kikako a ua manaʻo ʻia e nā ʻepekema ma mua o 300 miliona mau makahiki. Maliʻa paha ua manaʻo ʻia kā lākou mea kaua make e pale aku i kēia mau mea palupalu mai nā kamaʻāina nunui o ka hohonu o kēlā au.
