Njengoba icishe ibe sobala, ikhukhuleka olwandle futhi ihlanganisa cishe namanzi kuphela: i-jellyfish iphakathi kwezilwane eziyinqaba emhlabeni.
Izici
Ibukeka kanjani i-jellyfish?
I-Jellyfish iyingxenye ye-cnidarian phylum kanye nokuhlukaniswa kwe-coelenterates. Umzimba wakho wakhiwe izingqimba ezimbili kuphela zamangqamuzana: engaphandle emboze umzimba nengaphakathi elizungeza umzimba. Kukhona i-gelatinous mass phakathi kwezingqimba ezimbili. Lokhu kusekela umzimba futhi kusebenza njengendawo yokugcina umoya-mpilo. Umzimba we-jellyfish ungamaphesenti angama-98 kuya kwangu-99 wamanzi.
Izinhlobo ezincane kunazo zonke zikala i-millimeter ububanzi, enkulu kunazo zonke ngamamitha amaningana. I-Jellyfish ivamise ukubukeka ime njengesambulela eceleni. Induku yesisu iphuma ngaphansi kwesambulela, ngaphansi kwayo kukhona ukuvuleka komlomo. Amathende ajwayelekile: Ngokuya ngezinhlobo zezilwane, angamasentimitha ambalwa afika kumamitha angama-20 ubude. Zisetshenziswa i-jellyfish ukuze zizivikele futhi zibambe inyamazane yazo.
La matende afakwe amangqamuzana ahlabayo angaba ngu-700,000, lapho izilwane zikwazi ukukhipha khona ushevu okhubazayo. I-Jellyfish ayinabo ubuchopho, amaseli ezinzwa kuphela atholakala kungqimba lwamaseli olungaphandle. Ngosizo lwayo, i-jellyfish ingakwazi ukubona izinto ezishukumisayo futhi ilawule izenzo zayo nokusabela kwayo. Ezinye izinhlobo ze-jellyfish kuphela, njengebhokisi le-jellyfish, ezinamahlo.
I-Jellyfish inekhono elihle kakhulu lokuvuselela kabusha: uma ilahlekelwa itende, isibonelo, ikhula ngokuphelele.
Ihlala kuphi i-jellyfish?
I-Jellyfish ingatholakala kuzo zonke izilwandle zomhlaba. Uma ulwandle lubanda, ziba mbalwa izinhlobo ze-jellyfish ezikhona. I-jellyfish enobuthi kakhulu ihlala ikakhulukazi olwandle olushisayo. I-Jellyfish ihlala emanzini kuphela futhi cishe olwandle kuphela. Nokho, ezinye izinhlobo zase-Asia zisekhaya emanzini ahlanzekile. Izinhlobo eziningi ze-jellyfish zihlala emanzini angaphezulu, kuyilapho i-deep-sea jellyfish ingatholakala ekujuleni okungafika kumamitha angu-6,000.
Yiziphi izinhlobo ze-jellyfish ezikhona?
Cishe izinhlobo ezingu-2,500 ze-jellyfish ezaziwayo kuze kube manje. Izihlobo eziseduze ze-jellyfish, isibonelo, ama-anemones olwandle.
I-jellyfish iba neminyaka emingaki?
Lapho i-jellyfish isikhiqize inzalo, umjikelezo wabo wokuphila ngokuvamile uphela. Amathende ayahlehla futhi okusele yi-jelly disc, edliwa ezinye izilwane zasolwandle.
Ukuziphatha
I-jellyfish iphila kanjani?
I-Jellyfish iphakathi kwezidalwa ezindala kunazo zonke emhlabeni: sezihlale olwandle iminyaka eyizigidi ezingu-500 kuya kwezingu-650 futhi azikashintshi kusukela lapho. Naphezu kwemizimba yabo elula, bangabasindile beqiniso. I-Jellyfish inyakaza ngokwenza isivumelwano futhi idedele isambulela sayo. Lokhu kuzivumela ukuthi ziye phezulu nge-engeli, efana ne-squid, zisebenzisa uhlobo lwesimiso sokuhlehla. Bese behlehla kancane.
I-Jellyfish itholakala kakhulu emisinga yolwandle futhi ivame ukuzivumela ukuba ithwalwe yiyo. I-jellyfish esheshayo i-jellyfish enqamulayo - ihlehla ngesivinini esingamakhilomitha ayi-10 ngehora. I-Jellyfish iyazingela ngamathente ayo. Uma inyamazane ibanjwa ematendeni, amangqamuzana ahlabayo “aqhuma” futhi ajikijele izinaliti ezincanyana esilwaneni sawo. Ubuthi bembabazane obukhubazekile bungena esilwaneni ngala mahabhu amancane anobuthi.
Yonke le nqubo yenzeka ngesivinini sombani, ithatha ikhulu nezinkulungwane zomzuzwana. Uma thina bantu sihlangana ne-jellyfish, lobu buthi be-nettle buvutha njengezimbabazane, futhi isikhumba sibe bomvu. Ngobuningi be-jellyfish, njenge-jellyfish ehlabayo, lokhu kubuhlungu kithi, kodwa akuyona ingozi ngempela.
Kodwa-ke, i-jellyfish ethile iyingozi: isibonelo i-Pacific noma i-jellyfish yekhampasi yaseJapane. Okunobuthi kakhulu umnyovu wasolwandle wase-Australia, ushevu wawo ungabulala ngisho nabantu. Inamathendekele angama-60 angamamitha amabili kuya kwamathathu ubude. Ubuthi balokho okubizwa ngokuthi isikebhe samaPutukezi nabo bubuhlungu kakhulu futhi ngezinye izikhathi bayabulala.
Uma uhlangana ne-jellyfish, akufanele neze uhlanze isikhumba sakho ngamanzi ahlanzekile, ngaphandle kwalokho, ama-capsules we-nettle azoqhuma avuleke. Kungcono ukwelapha isikhumba ngeviniga noma ukusihlanza ngesihlabathi esimanzi.
Abangane nezitha ze-jellyfish
Izitha zemvelo ze-jellyfish zifaka izidalwa zasolwandle ezahlukahlukene njengezinhlanzi nezinkalankala, kodwa nezimfudu namahlengethwa ama-hawksbill.
I-jellyfish izala kanjani?
I-Jellyfish izala ngezindlela ezahlukene. Bangakwazi ukuzalana ngokwesondo ngokuchitha izingxenye zemizimba yabo. I-jellyfish yonke ikhula kusukela ezigabeni. Kodwa futhi zingazalana ngokobulili: Ngemva kwalokho zikhiphela amangqamuzana amaqanda nezidoda emanzini, lapho zihlangana khona. Lokhu kubangela isibungu se-planula. Inamathela emhlabathini futhi ikhule ibe okuthiwa i-polyp. Ibukeka njengesihlahla futhi iqukethe isiqu namatende.
I-polyp ikhiqiza ngendlela engavamile ngokucindezela i-jellyfish encane emzimbeni wayo, ekhula ibe i-jellyfish. Ukushintshaniswa kokuzalana ngokocansi kanye nokungahloniphi kubizwa ngokuthi ukushintshana kwezizukulwane.
Care
Idlani i-jellyfish?
Ezinye i-jellyfish ziyizilwane ezidla inyama, ezinye njenge-cross jellyfish ziyizilwane ezidla uhlaza. Ngokuvamile zidla ama-microorganisms afana ne-algae noma i-plankton yezilwane. Abanye baze babambe nezinhlanzi. Inyamazane ikhutshazwa ubuthi be-jellyfish bese ithuthelwa emlonyeni ovulekile. Asuke lapho angene esiswini. Lokhu kungabonakala ku-gelatinous mass ye-jellyfish ethile. Isesimweni sezindilinga ezine ezimise okwesicathulo samahhashi.
Ukugcinwa kwe-jellyfish
I-Jellyfish inzima kakhulu ukuyigcina emanzini njengoba ihlale idinga ukugeleza kwamanzi. Izinga lokushisa lamanzi nokudla kufanele kube ngokufanele ukuze baphile.
