Abaningi bezwile ukuthi isilwane esikhulu kunazo zonke emhlabeni wethu yi-blue whale. Kepha hhayi wonke umuntu uyazi ukuthi kunezidalwa ezikudlula ngosayizi - lo ngumhlali wasolwandle i-cyanea jellyfish.
Incazelo kanye nokubukeka kohlanga
I-Arctic cyanea kubhekisa ezinhlotsheni ze-scyphoid, i-oda le-discomedusa. Kuhunyushwe kusuka ku-Latin jellyfish cyanea kusho izinwele eziluhlaza okwesibhakabhaka. Zihlukaniswe ngezinhlobo ezimbili: i-Japanese ne-blue cyane.
I-jellyfish enkulu kunazo zonke emhlabeni, usayizi ushukela nje umdondoshiya... Ngokwesilinganiso, ubukhulu bensimbi ye-cyanea bungamasentimitha angama-30-80. Kodwa izinhlobo ezinkulu ezirekhodiwe zazingamamitha ayi-2.3 ububanzi namamitha angu-36.5 ubude. Umzimba omkhulu ungamanzi angama-94%.
Umbala wale jellyfish uncike kubudala baso - indala isilwane, okukhazimulayo nokugqamile kwedome nezintambo. Izinhlobo ezindala ikakhulukazi ziphuzi futhi ziwolintshi ngombala, ngobudala ziba bomvu, zijike zibe nsundu, bese kuvela onsomi onsomi. Ku-jellyfish yabantu abadala, idome iba phuzi phakathi, bese iba bomvu emaphethelweni. Izintambo nazo ziba imibala ehlukene.
Esithombeni i-cyanea enkulu
Insimbi ihlukaniswe yaba izingxenye, ziyi-8. Umzimba u-hemispherical. Izingxenye zihlukaniswe ukusikwa okuhle okubukekayo, emazansi awo okuyizitho zombono nokulinganisela, iphunga nokutholwa kokukhanya okufihliwe ku-ropalia (ama-corpuscle asemaceleni).
Ama-tentacles aqoqwe ngezinqwaba eziyisishiyagalombili, ngasinye sinezinqubo ezinde ezingama-60-130. Itende ngalinye linama-nematocysts. Sekukonke, i-jellyfish inezinsalela eziyinkulungwane nengxenye, ezakha "izinwele" eziwugqinsi kangako ushukela okubizwa "ezinoboya"Noma" umane wengonyama ". Uma ubheka isithombe se-cyane, lapho-ke kulula ukubona ukufana okucacile.
Maphakathi nedome kukhona umlomo, lapho izindwani zomlomo obomvu klebende zibomvu khona. Uhlelo lokugaya ukudla lubandakanya ukuba khona kwemisele emikhulu egudla esiswini iye ezingxenyeni eziseceleni nezomlomo zedome.
Kuboniswe i-arctic cyanea jellyfish
Ngokuphathelene Ingozi ushukela okomuntu, ngakho-ke akufanele ukhathazeke kakhulu. Lobu buhle bungakuluma kuphela, bungadluli ngaphezu kwezimbabazane. Ngeke kube khona ukukhuluma ngokufa, ukushiswa okuphezulu kuzosusa ukungezwani komzimba. Noma, izindawo ezinkulu zokuxhumana zisazoholela ekuzweleni okuqinile okungathandeki.
Indawo yaseCyanea
UCyanea jellyfish uyaphila kuphela emanzini abandayo olwandle i-Atlantic, Arctic kanye nePacific. Kutholakala eBaltic naseNyakatho Yezilwandle. Ama-jellyfish amaningi ahlala ogwini olusempumalanga yeGreat Britain.
Ukuqoqwa okukhulu kwabonwa ngasogwini lwaseNorway. Izilwandle ezifudumele eziMnyama nezase-Azov azimfanele, njengawo wonke amanzi eningizimu yezwe. Bahlala okungenani i-42⁰ latitude latitude.
Ngaphezu kwalokho, isimo sezulu esibuhlungu sizuzisa kuphela lezi jellyfish - abantu abakhulu kakhulu abahlala emanzini abandayo. Lesi silwane sitholakala futhi ngasogwini lwase-Australia, kwesinye isikhathi siwela ezingeni elipholile, kepha asihlumi lapho futhi asikhuli ngaphezu kwamamitha ayi-0.5 ububanzi.
I-Jellyfish ayivamile ukubhukuda ifike ogwini. Bahlala kukholamu yamanzi, babhukuda lapho ekujuleni okungaba ngamamitha angama-20, bazinikele kwesamanje futhi bahambisa amatende abo ngobuvila. Inqwaba enkulu kangaka yezintambo eziminyene, ezilumayo kancane iba ikhaya lezinhlanzi ezincane nezingenamgogodla ezihambisana ne-jellyfish, zithole ukuvikelwa nokudla ngaphansi kwedome yayo.
Indlela yokuphila yaseCyanean
Njengoba kufanele i-jellyfish, ushukela ayihlukile ngokunyakaza okubukhali - kumane nje kuyantanta nokugeleza, kwesinye isikhathi kungenelela idome futhi kuphephezeliswe amatende alo. Ngaphandle kokuziphatha kokungenzi lutho, i-cyanea iyashesha kakhulu i-jellyfish - iyakwazi ukubhukuda amakhilomitha ambalwa ngehora. Imvamisa, le jellyfish ingabonakala ikhukhuleka ebusweni bamanzi enezintambo zayo ezinwetshiwe, ezakha inethiwekhi yonke yokubamba inyamazane.
Izilwane ezidlayo, zona, ziyizinto zokuzingelwa. Ziphila ngokudla izinyoni, izinhlanzi ezinkulu, amajeli kanye nezimfudu zasolwandle. UCyanea ngesikhathi somjikelezo we-medusoid uhlala kukholamu yamanzi, futhi ngenkathi iseyipolyp, ihlala ezansi, izinamathisela esiteji esingezansi.
UCyaneus ebizwa kanjalo futhi ulwelwe oluhlaza sasibhakabhaka... Leli yiqembu lasendulo kakhulu lezinto eziphila emanzini nasemhlabeni, okubandakanya izinhlobo ezibalelwa ku-2000. Abahlanganise lutho ne-jellyfish.
Ukudla
UCyanea ungowezidliwayo, futhi kunalokho uyisiminzi. Idla nge-zooplankton, izinhlanzi ezincane, ama-crustaceans, ama-scallops, ne-jellyfish encane. Eminyakeni elambile, angadla isikhathi eside ngaphandle kokudla, kepha ngezikhathi ezinjalo uvame ukuhlanganyela ekudleni komuntu.
Ukuntanta ngaphezulu ushukela kubukeka njengesigejane ulwelwe, lapho izinhlanzi zibhukuda khona. Kepha ngokushesha nje lapho isisulu sithinta izintambo zaso, i-jellyfish ngokungazelelwe iphonsa ingxenye yobuthi ngamaseli ahlabayo, isonge isilwane bese isihambisa lapho iya khona ngomlomo.
Ubuthi bufihlwa kuyo yonke indawo nobude betende, isisulu esikhubazekile siba yisidlo somzingeli. Kodwa-ke, isisekelo sokudla yi-plankton, ukwehluka okungaziqhayisa ngamanzi abandayo olwandle.
UCyanea uvame ukuyozingela ezinkampanini ezinkulu. Basakaza amatende abo amade emanzini, ngaleyo ndlela bakhe inethiwekhi eminyene futhi enkulu yokuhlala.
Lapho abantu abadala abayishumi nambili beyozingela, balawula amakhulukhulu wamamitha wobuso bamanzi ngamatende abo. Kunzima ukuthi isisulu sishelele singabonwa ngalezi webhu ezikhubazayo.
Ukuzala kanye nesikhathi sokuphila
Ukuguqulwa kwezizukulwane kumjikelezo wempilo we-cyanea kukuvumela ukuthi kukhiqize ngezindlela ezahlukahlukene: ezocansi kanye ne-asexual. Lezi zilwane zingabobulili obuhlukile, abesilisa nabesifazane benza imisebenzi yabo yokuzala.
Abantu bobulili obuhlukile be-cyanea bahlukile kokuqukethwe kwamagumbi akhethekile esiswini - kwabesilisa kula magumbi kune-spermatozoa, kwabesifazane kukhona amaqanda. Abesilisa bakhipha isidoda emvelweni wangaphandle ngomlomo womlomo, kuyilapho kumakamelo ezinsikazi ezinsikazi atholakala ezindlebeni zomlomo.
Isidoda singena kula makamelo, sivundise amaqanda, futhi ukuqhubeka kokuthuthuka kwenzeka lapho. Iplanethi echanyuselwe ibhukuda iphume futhi intante kukholamu lamanzi izinsuku ezimbalwa. Bese banamathisela phansi bese bephenduka i-polyp.
Le scyphistoma isondla ngenkuthalo, ikhula izinyanga ezimbalwa. Kamuva, umzimba onjalo ungazala ngokuhluma. Indodakazi polyp bahlukaniswe main.
Entwasahlobo, ama-polyps ahlukaniswe ngesigamu futhi kwakhiwa kuwo ama-ether - izibungu ze-jellyfish. "Izingane" zibukeka njengezinkanyezi ezincane ezinamaphoyinti ayisishiyagalombili ngaphandle kwama-tentacles. Kancane kancane, lezi zingane zikhula futhi zibe yi-jellyfish yangempela.
