I-Jellyfish ayisoloko iphila njenge-jellyfish. Xa zisebancinci, zihlala ngokuqinileyo ezantsi kolwandle kwaye zibizwa ngokuba ziipolyps. Ethubeni bayaphuma emazantsi baze badada emanzini, emva koko baqubhe ngokukhululekileyo. Emva koko zibizwa ngokuba yijellyfish.
I-Jellyfish ihlala elwandle kwaye itya izilwanyana ezincinci, i-crustaceans, kunye nemibungu yezinye izilwanyana. I-jellyfish enkulu iya kutya enye i-jellyfish okanye intlanzi encinci. I-Jellyfish iyakwazi ukwahlula phakathi kokukhanya nobumnyama. Anamehlo akhethekileyo abizwa ngokuba "amehlo acwebileyo". Iliso ngalinye kula lineeseli ezininzi zeemvakalelo. Oku kubavumela ukuba baqaphele umthombo wokukhanya okanye isithunzi.
Umzimba we-jellyfish unenxalenye ephezulu efana neambrela. Zihamba ngokufunxa amanzi emizimbeni yazo zize ziwakhuphe ngokukhawuleza. Ikhangeleka njengesambrela osivula kancinane kwaye sivale ngokukhawuleza kwakhona.
“Iminatha” ibekwe kwicala elingaphantsi. Iminatha inetyhefu esetyenziswa yile jellyfish ukuze yothuse ixhoba layo. Ubuthi benye ijelifish bunokuba yingozi ebantwini: ukuba uyazibamba, uziva iintlungu, kwaye ulusu luyarhawuzelela lujike lubebomvu. Ngamanye amaxesha ufumana amadyunguza nawe. Ityhefu yeentlobo ezimbalwa inokude ikubulale. Nangona kunjalo, i-jellyfish eninzi ayinabungozi ebantwini. E-Asiya, i-jellyfish engeyiyo inetyhefu iyabanjwa kwaye ityiwe.
Zizala njani ijellyfish?
Inkunzi nemazi ziyafuneka ukuze zizale. Ukuchumisa kwenzeka emanzini. Oku kubizwa ngokuba kukuzala ngokwesondo. Umbungu omncinane ukhula kwiseli yeqanda eliqhame. Umbungu udada ukuya kwilitye elifanelekileyo okanye ikorale uze unamathele apho. Emfanekisweni, la ngamanani u-1 ukuya ku-4.
Ukususela ngoku isilwanyana siyi-polyp. Inokuzenza uhlobo lwamawele kunye nabantakwenu abaninzi abafana kanye. Inye kuphela i-polyp eboniswe emfanekisweni.
Kwixesha elizayo elifanelekileyo, i-polyp yolula kwaye idibanise kwiindandatho zomntu ngamnye. Le yimifanekiso 5 ukuya kwi-10. Ezi polyps zimillimeters ezimbalwa kuphela ngobukhulu.
Umzobo we-11 ubonisa iiringi ezizimeleyo eziqhawulayo. Iringi nganye yijellyfish ezimeleyo. Konke oku kunye kukuveliswa kwe-asexual. Emva koko wonke umjikelo uqala kwakhona.
