Ijellyfish

Nangona i-jellyfish ayizizo izilwanyana esithanda ukuzibona ngokusondeleyo, ngakumbi ukuba enye yeentente zabo iyasichukumisa, kukho iindidi ezininzi ezahlukeneyo kwizilwanyana zaselwandle. Ngokukodwa, zikho ngaphezu kwe-1.500 yeentlobo ezahlukeneyo zejellyfish, kwaye iingcali ngokwazo zicinga ukuba azikho zonke ezifunyenweyo. Izinto ezininzi ezingaziwayo zihlala enzulwini yolwandle, ngoko ke ezintsha zinokufunyanwa kwiminyaka ezayo.

Ukuba ufuna ukwazi ngakumbi ngezi zilwanyana kwaye ufumanise iimpawu zazo, ukuba zizala njani, zitya ntoni ... qiniseka ukuba ujonge kulo lonke ulwazi esiluqulunqileyo.

Zinjani ijelifish

I-Jellyfish, ebizwa ngokwesayensi medusozoa, zikwabizwa ngokuba ziinyembezi zolwandle, i-aguamalas (okanye i-malaguas), i-aguavivas, i-aguacuajito okanye i-aguacuajada. Zizilwanyana zaselwandle ze-pelagic, oko kukuthi, zihlala elwandle kwikholamu yamanzi engekho kwindawo yelizwekazi. Ubungakanani bayo buqhelekile phakathi kwe-5 kunye ne-40 yeesentimitha ubudeKuxhomekeke ekubeni luhlobo luni na. Kukho ezinye ezikwaziyo ukufikelela kwiisentimitha ezingama-200 ububanzi (kunye naloo mfanekiso kubunzima bazo).

I-96% yomzimba wakho yenziwe ngamanzi. Oku kubonakala ngokuba ne-gelatinous kunye nokumila kwentsimbi. Kuyo kuxhoma into ebizwa ngokuba "yi-handlebar ye-tubular." Inomlomo kunye nothotho lweentente ezithwele iiseli ezihlabayo ezisebenzisayo ukuzikhusela okanye ukubamba ixhoba layo.

Elwandle ishukuma ngendlela enomdla ekubeni ikwenza oko ngokucutheka emzimbeni wayo, ithatha amanzi ize iwakhulule njenge-propeller ukuze ihambe. Into ekufuneka iphawulwe kukuba banokunyuka okanye behle ngolu hlobo kuphela, hayi emacaleni (oku kuxhomekeke kwimisinga yolwandle ngokwawo, yiyo loo nto ngamanye amaxesha befikelela kumanxweme).

Nangona isisilwanyana esiphilayo, isibakala sokuba ayinabo ingqondo iyacaca. I-Jellyfish isebenzisa ii-nerve receptors ezizinceda ukuba ziphile.

Ngokubhekiselele kubomi obulindelekileyo, yahluke kakhulu ngokuxhomekeke kuhlobo oluthile. Ngelixa abanye baphila malunga neeyure ezi-2 kuphela, kukho ezinye iintlobo ezinokwenza iinyanga ezi-6. Yaye abanye banokude baphile ngonaphakade.

Indawo yokuhlala

ijellyfish iphila kwiindawo zamanzi ashushu kunye neetropiki. Nangona kunjalo, ngenxa yokuqhelana kwazo, ziyakwazi ukufunyanwa kwezinye iilwandle kunye nolwandle olunamanzi abandayo okanye ashushu. Enyanisweni, ziyakwazi ukumelana namaqondo obushushu aphakathi kwe -6 degrees celcius nama 31 degrees.

Into eqhelekileyo kukuba basemanzini aphakathi kwe-9 kunye ne-19 degrees. Zihlala zihlala zixhaphakile kulwandlekazi lwaseIndiya, lweAtlantiki kunye nePasifiki, nangona ezinye iintlobo zejellyfish zinokufumaneka kwiMeditera.

iintlobo zejeli

Zonke iindidi zeejellyfish eziselwandle azikaziwa, ekubeni ezi ngaphezu kwe-1.500 ingezizo ezo zikhoyo ngokwenene, kodwa ezinye ezininzi ezingekafunyanwa. Nangona kunjalo, ezinye zazo, ezaziwa kakhulu, zezi zilandelayo:

i-portuguese caravel

I-jellyfish eyahluke kakhulu kwinkangeleko yayo kwizinto eziqhelekileyo, kunye nendlela yayo yokuphila, kuba ithanda ukudada phezu kwamanzi, kwaye sele ifunyenwe kwintlabathi emanxwemeni.

Iphawulelwe phuma emanzini ushiya iintente zikhululekile yaye ngaloo ndlela erhintyela amaxhoba ayo. Ngokubonakalayo, kubonakala ngathi ibhegi okanye efanayo, kodwa eneneni yijellyfish.

Ijellyfish ye-cannonball

Inemilo engqukuva ephantse igqibelele, imhlophe, imdaka okanye ibhlowu ngombala. Nangona banokukhohlisa ngenkangeleko yabo, kuba kubonakala ngathi abanazo iintente, inyaniso kukuba banayo, kuphela bafihliweyo kwaye bathumela kuphela ukuba bahlasele amaxhoba abo okanye bazikhusele.

iqhosha eliluhlaza

yakhe ifana kakhulu ne-algae, Ngoko ke, zibeka ingozi xa uhamba elunxwemeni okanye emanzini kwaye ufuna ukuzichukumisa ukuze uzisuse kuwe, ukholelwa ukuba azizozilwanyana. Kwakhona, zincinci kakhulu, kodwa ziyingozi nje ukuba ziyakuluma.

ijellyfish yenyanga

Yenye yezona yaziwa kakhulu kuzo zonke iilwandle kunye neelwandle, njengoko iqhelane kakuhle nayo yonke imimandla. Ikwaluhlobo oluqhelekileyo esicinga ngalo xa igama elithi "jellyfish" lifika engqondweni kuba imilo yayo iqhelekile kwezi zilwanyana.

ijellyfish isikhephe

Le mhlawumbi yenye yezona, ukuba udibana nayo, ungoyiki ukuyiphatha, kuba, nangona inetyhefu, le engenabungozi ebantwini kwaye ngokubonakalayo ijellyfish yenye yezona zintle kakhulu. Ngobukhulu nje be-7 centimeters, umbala wabo ohlaza okwesibhakabhaka (kwimithunzi eyahlukeneyo), kunye negolide kunye ne-transparent, yenza ukuba ibe yinto ephawulekayo.

Bahlala, njengendoda yamaPhuthukezi, phezu kwamanzi, beshiya iintente zabo ukuba zihambe ngokukhululekile emanzini ukuze zibambe ukutya kwazo kwaye zikwenze ngaphakathi.

Ukutyisa i-jellyfish

Nangona imilo yabo engaqhelekanga, inyaniso kukuba i-jellyfish inomlomo kwaye ngenxa yoko bazisa ukutya kwabo. Ukongeza, nabo banesisu kunye namathumbu. Ukutya kwabo kusekelwe ekutyeni ezinye izilwanyana, oko kukuthi, badla inyama. Ngapha koko, eyona nto bayitya kakhulu ziintlanzi ezincinci, iintlobo zejellyfish ezincinci, iicrustaceans, iimollusks, imibungu, amaqanda, kwaye ewe, iiplankton nazo.

Ukuze batye, basebenzisa iintente zabo, bakwazi ukubamba amaxhoba abo (kwaye bawatofe “ngetyhefu” abayiphetheyo) ukuze angaphuncuki okanye ashukume. Zizithatha zizise emlonyeni kwaye kungaphakathi apho inkqubo yokucubungula eso silwanyana yenzeka khona.

Ukuveliswa kwejelifish

Ukuzala kweJellyfish kubandakanya ukwahlula amadoda, imazi kunye nesampulu ye-hermaphrodite, oko kukuthi, ukuba nezini zombini kumntu omnye. Le yokugqibela ayiqhelekanga, kodwa kusenokuba njalo, ngoko bebengayi kufuna esinye isilwanyana ukuphumeza inkqubo.

Ngokubanzi, ukuzala kwenzeka xa amaqanda kunye nesidoda zikhutshelwa emanzini; ukudibanisa kule ndlela inye. Kodwa kunokwenzeka ukuba ukuchumisa kwenzeke ngaphakathi kwebhinqa, ukwazisa amadlozi ukuze afikelele kwii-ovules.

Ngokuxhomekeke kwiintlobo zejellyfish, le nkqubo inokuthatha nje imizuzu embalwa, okanye unyaka nangaphezulu. Ingenzeka unyaka wonke, nangona kusehlotyeni xa kukho ukwanda okuthe kratya ngenxa yobushushu bobushushu kunye nokwanda kokutya okukhoyo.

Nje ukuba ukukhwelana (okanye ukuchumisa) kwenzeke, amaqanda ayakhiwa aze akhuphe umbungu. Oku kubizwa ngokuba yi "planula" kwaye imile okwepere. Ihlala inamathele kwijellyfish ngeentente zayo de, emva kwexesha elithile, yahlukane ize idada emanzini de ifumane into yokuncamathela.

Xa iyifumana, iqala isigaba sayo esilandelayo, esisisigaba se-polyp, apho iqala khona phuhlisa amalungu aqinileyo omzimba wakho (umlomo, iintente…). Esi sigaba sithatha malunga nonyaka omnye, ngelo xesha baya kuphuma kwindawo apho bezilungiselelwe ukuhamba ngokukhululekileyo, sele befana nejelifish.
