Ka 'ole o ka jellyfish. Ka 'ole o ka Scyphozoa

Mawaena o ka wai invertebrates - poʻe i noho ma kai, i ka pae o ka meaola i kapaia scyphoids. Ka mea, i mau liluwelo pepa - polypoid a medusoid wehewehe aku ma kā lākou'anatomia a me kaʻaoʻao o ke ola. He 'atikala e nānā i ka' ole o ka jellyfish, e like me nā hiʻona o kona ola.

General ano Class scyphoids

Mau meaola mea o keʻano coelenterates a me ka mea wale nō nā meaola kai. Scyphomedusae, nā kiʻi a i hōʻike ma lalo i ka bele a mamalu kinona o ke kino, a me ia iho - ka aniani moakaka a me ka gelatinous, he o mesogloea. A pau o nā holoholona o keia ano i ka lua o ka papa ma nā mea kūʻai mai, a hānai ma zooplankton.

No ka meaola wehewehe aku ma ka kahahānai (kahahānai) symmetry o ke kino. Anatomically'ālike māhele, e like me na nā'aʻaʻa a me nā loko manaʻo radially mai ka lonikū waena iho (axis). He hoʻomaopop 'ana i loko o ka holoholona, passively lana ana ma ka wai kolamu, like hoʻi me kēlā mau? Ueo i mea sedentary (Anemone) a lohi kolo ana ma ka kūpapakū (starfish, kai urchins).

Mawaho 'ole. kaianoho koholā

Mai scyphoids 'elele i mau lifeforms - jellyfish a me polyps, nānā i kā lākou' anatomia i, a i kekahi oko ao. Initially mākou hoʻokolokolo i ka mawaho 'ole o ka jellyfish. Haliu ae la ia i ka holoholona waihona ipu bele i lalo, loaʻa mākou i ka waha ka i kokoke ma ka tentacles. Ua hanaʻia mau oihana: Komo 'o ia māhele o ka ai, a lawe aku oe i na koe undigested ia mai. Oia meaola i kapaia protostomes. Ka holoholona ka kino papalua, ahu iho ninoieo o ectoderm a me ka endoderm. Ka hope pepa i ka gut (ka gastric) lua. Nolaila i ka inoa: keʻano o nā coelenterates.

Kahi nahā i waena o nā papa o ke kino ua piha me ka aniani moakaka jelly-e like nuipa - mesoglea. Ectodermal keena hana i ke kākoʻo, Hawaii a me ka aiiay kuleana pili i. Ka holoholona i ka ili-muscular eke, ka hoʻolako 'kona o ka neʻeʻana i loko o ka wai. Ke anatomical 'ole o ka jellyfish meaʻano huikau, e like me ka ecto- a me ka endoderm e differentiated i loko o kekahi mau halepaahaoʻAno. Ma waho uhi a me ka Muscle i loko o ka pā, ahu iho ua oi waena keena, regenerative pae'ōnaehana hiʻona (o i ke ola i ka poino hapa o ka holoholona kino).

Interestingly ka 'ole o ka neurocytes ma scyphoids. Ka mea, i hoku-hoʻokino a me kā lākou mau keʻano o ka hanaʻana i ka wili ka ectoderm a me ka endoderm, ho okumu i huhui - ekalesia. ʻO ko mākou hopohopo nenoaiu o kēia 'ano ua kapaia eiei.

Endoderm a me kona oihana

I ka pahale loko, ahu iho ano ma scyphoids gastrovascular'ōnaehana mai ka intestinal lumen kukuna e haele oukou pela digestive auwai a hoalaala ia e glandular (pee i ka digestive wai) a me ka phagocytic keena. Mau hale a mau i ka papa kuhikuhiE aeee e hoohiolo no ia i ka ai (particles). no hoi ke komo ka digestionʻili a me ka muscular 'ole o ka eke. Ka mea, hana pseudopodsʻili lahilahi, a me ka pīhoihoi o ka retractors ke aloha (particles). Phagocytic keena a me pseudopods digestion ua lawe mai ÿelua: intracellular (e like protists) a me ka cavitary hoʻomaopop 'ana i kokua i hoʻonohonoho' ia multicellular holoholona.

stinging keena

E hoʻomau i ka noiʻi i ka 'ole o Scyphozoa a noʻonoʻo i keʻano papa hana ana i na holoholona i hoomaluia, e like me ka hoʻouka i kekahi ikehu nāna. Ma scyphoids he mea kekahi kahua hoʻonohonohoʻana inoa: Cnidarians papa. Ua huli mai ia i loko o ka ectodermal, ahu iho, ua hoonohonoho ka mea kūikawā keena - paʻapū, a stinging, nō kapa knidotsitami. Ka mea, i aia a puni o ka waha, a ma luna o nā holoholona tentacles. Ma lalo o ka hana a me mechanical stimuli ka pae aia i loko o ka mea hōʻikeʻikeʻuʻuku paʻapū keena hoʻomaka koke kipaku a puka nō ia o ka luahi ka kino. Scyphoids toxins, penetrating knidotsel i ona i ka plankton invertebrates a me ka iʻa larvae. Ma kānaka ka mea, i symptoms o urticaria a me ka ili hyperthermia.

makaukau no

Ma nā kihi o ka jellyfish bele, Hawaii photo hooku iho la ia ia ma lalo nei, e hiki ke ike i ka hoʻopōkole tentacles, kapa mokuna keena - rhopalium. mau sensory hui, i loaʻa i loko o ia mau mea: maka (maka i pane koke i ka malamalama) a me ka equilibrium (statocysts, me ke ano o ka limestoneʻiliʻili). Me kā lākou kōkua scyphoids aʻo e pili ana i ka hookokoke ana mai o ka ino: nä hawewe kani i loko o ka laulā o ka 8 i ka 13 Hz nāuki mai statocysts a me ka holoholona koke hele hohonu i loko o ke kai.

Reproductive'ōnaehana a me nā'ōlelo

Hoomau ana i ka noiʻi i ka 'ole o ka jellyfish (kiʻi hoikeia ma lalo nei), e kālele ana ma luna o ka reproductive'ōnaehana scyphoids. Ua ua poe ma na gonads, o kaʻekeʻeke hana gastric lua ka ectodermal kumu. No kēia mau holoholona e dioecious, i ka hua, a me ka sperm puka mai ma ka waha a me ka fertilization ia lŘlŘ i loko o ka wai. Zygote hoomaka palaoa a me ka ho okumu i ka hookahi-ahu iho germ - blastula, a mai ia - larva kapa planuly.

Ua lana o ka 'elele, ua laila, pili i ka kūpapakū, a lilo i ka polyp (stsifistomu). Ua hiki hoʻo'ōpuʻu, akā, mea i hiki ke strobilation. Ho okumu i kekahi noae o opiopio jellyfish kapaʻia nā mea kemika. Ka mea, e pili ana i ke kikowaena mau lala. Ka 'ole o ka jellyfish, kaʻawale mai ka strobe, i keia: ia i ka kahahānai Kanal'ōnaehana, waha, tentacles, rhopalium, a me nā lā mua o ka' īnea i glands.

Pela, ke 'ole ÿokoÿa mai jellyfish asexual stsifistomy kanaka i loaʻa i ka conical kinona, a me ka nui o ka 1-3 mm o ua pili i ka ili Via ka ōhāhā. Waha hoʻopuni lei o tentacles, a me ka gastric lua māheleʻia i loko o 4ʻekeʻeke.

Pehea e neʻe scyphoids

Medusa hiki ia oe mokulele hēkī propulsion. Ua ho opa ao pushes ka hapa o ka wai a me ka höʻike ana. Mamalu o ka holoholona i ka mea ia manawa hoemi i 100-140 manawa no minuke. Këia i ka 'ole o Scyphozoa, no kekahi laʻana, a Rhizostoma Aurelia, ua kaulana mākou ia anatomical hale e like me kaʻili-muscular sac. Ua Ua Aia i loko o ka ectoderm, keena kupono no kona efferent neural kaʻe puluniu mau apo, a me nā aka wahi. Excitation ua ho'īliʻili-muscular nā hale, no laila, i ka mamalu ua'opihia, laila, hanaʻino, e hookuke i ka holoholona mua.

Hiʻona o ka kālaikaiaola scyphoids

Mau elele o ka papa o coelenterates, he pono ole i ka mehana kai, a ma ka anu Arctic wai. Aurelia - Scyphozoa, kino 'ole a mākou i aʻo, ke ola i loko o ka Black, Azov. Aia Ua laha, a me ka kekahi Luna o keia ano - Rhizostoma (rizostoma). Kona nō-keʻokeʻo mamalu me ka poni, a me ka uliuli kihi a me protuberances moʻolelo lobes e hoohalike ai aa. Vacationers ma ka Crimea iauaeoia oo? Ecia e maopopo nö iä ia o keia ano keia ano, a ho'āʻo e ia i loko o ka wai auau o kona mau 'elele mai like stinging holoholona aeee hiki i loa "'ā" o ke kino. Ropilema, like hoʻi me Aurelia, ke ola i loko o ke kai o Japan. Kala like 'ole kona rhopalium nonono a melemele, a me ka mea i lehulehu manamana-me ka ulu o ke. Mesoglea mamalu o nā laha 'ia i loko o ka lumi kuke o Kina a me lapana i kapaia "aniani ai."

Tsianeya - noho o ke anu Arctic wai, o ka mea nui loa jellyfish. Loa kona tentacles hiki 30-35 m, a me ka mamalu anawaena - 2-3.5 m + Lion ka Mane ai tsianeya huluhulu i mau subspecies :. Japanese a me ka uliuli. Ka ino o stinging aeee aia ma na kihi o ka mamalu, a ma luna o nā tentacles, ka noho pilikia loa ana i kānaka.

Ua aʻo mākou i ka 'ole o ka Scyphozoa, a ua ho'āpono ike i ke' o ko lākou mau ola.
