I-Arctic jellyfish yi-jellyfish enkulu kunayo yonke emhlabeni

I-Jellyfish ingenye yezidalwa ezithakazelisayo kakhulu eziphila emhlabeni. Umzimba wabo uqukethe i-mesogloea enamanzi - izicubu ezixhumayo, ngokubukeka kufana ne-jelly.

Ukuma kwalabahlali be-element element kufana nesambulela noma insimbi, i-mushroom noma inkanyezi, ngoba lezi zidalwa zinezithente ezincane. Ngakho-ke, bathola igama labo kusukela egameni lesiGreki ne "melas" yezimpande, okuhunyushwa ngokuhunyushwa ngokuthi "izinkanyezi ezimnyama" noma "izinkanyezi".

I-jellyfish enkulu kakhulu i-Cyanea capilata, ebizwa nangokuthi i-giant cyanide, i-cyanide yama-arctic, i-cyanide enezinwele noma ingonyama. Libhekisela ku-sciFiedus.

Ngo-1865, i-jellyfish enkulu yaphonswa ngasogwini ngemuva kwesiphepho eMassachusetts Bay. Ububanzi besambulela sakhe babuyi-2.29 m, ubude bezintambo kwakungamamitha angaba ngu-37! Izazi ze-zoologists zikholelwa ukuthi phakathi kwama- cyanides ama-arctic i -jellyfish enkulu kunazo zonke nge-ambulera ububanzi bamamitha amabili nesigamu namitha angamashumi amane angasetshenziswa.

I-cyanide enkulu ihlala engxenyeni esenyakatho ye-Atlantic nasePacific, kanye nasezilwandle zase-Arctic. Kodwa i-jellyfish enkulu kakhulu ayifinyeleli ngasogwini, ngakho bambalwa abantu abakwazi ukukuhlangabeza. Abantu, ebukela izithombe zabanenhlanhla, abakholelwa ekutheni bayakwazi ukungena, becabangela izithombehop. Noma kunjalo, ama-hulks anjalo atholakala emvelweni.

Ihambisa i-jellyfish enkulu kakhulu ngendlela esebenzayo, njengohlobo lwaso. Lapho inkontileka yemisipha evela emgodleni wesambulela, amanzi aphikisiwe kahle - lokhu kuvumela ukuthi into efana ne-jelly ifakwe ngokushesha emanzini.

Umbala womzimba we-jellyfish uhlukahluka kuye ngokuthi ubukhulu bawo bunjani. Izibonelo ezinkulu zibomvu, zibomvu, zibomvu futhi ziluhlaza okomnyama. Emaphethelweni kwesambulela kukhona izintambo (ziqoqwe ngezibopho eziyisishiyagalombili) kanye nezitho zokuzwa. Phakathi kwehlangothini elingaphansi (concave) umlomo, ozungezwe yi-lobes encane yomlomo omncane.

I-jellyfish enkulu kunazo zonke emhlabeni izondla izakhamuzi ezincane zasolwandle: i- plankton, ama-crustaceans, ama-mollusks, i-caviar yezinhlanzi nezinhlanzi ezincane. Yona ngokwayo ingaba nesidlo sakusihlwa kwezinye izinhlanzi ezinkulu. Ngokuvamile izidalwa ezincane zidliwa yizilwane zasolwandle.

I-jellyfish iyabhubhisa izisulu zayo ngobuthi obuthakathaka, ezisezinkalweni ezikhukhulayo ezitheni. Ngaphakathi kwamaseli ahlabayo ahlanganisa izintambo eside aphikisiwe. Ngaphandle, izinwele ezincane ziphuma ngaphandle, okuthi, lapho zithintwa, imililo efana ne-trigger, intambo iphonswa ngaphandle kwe-capsule iphinde ikhala kulesi sisulu. Futhi kakade kuhambisana nentambo ifika enobuthi. Isisulu esikhubazekile futhi esingenakunyakaziswa se-jellyfish sigijimela kancane emlonyeni wakhe ngosizo lwezitende kuqala, bese kuthi amacenge omlomo.

Kumele kuqashelwe ukuthi abantu abahlaseli i-jellyfish ngokwabo - abantu abakhathaleli ngento yokudla. Kodwa-ke, "ukushisa" ikakhulukazi okungavunyelwe ukufuna ukwazi nge-poison jellyfish kuyakwazi. Lezi zimakhemikhali ezishisayo, nakuba zingekho ezibulalayo, zibuhlungu kakhulu, ikakhulu uma i-jellyfish isayizi ngobukhulu.

I-jellyfish enkulu kakhulu emhlabeni iyanda ngale ndlela. Abesilisa baphonsa i-spermatozoa emanzini, ukusuka lapho bangena khona emzimbeni wesifazane bese bafaka amaqanda. Khona-ke amaqanda akhula abe ama-planula. Ngemuva kokushiya isidumbu se-jellyfish bese uhlada izinsuku ezimbalwa, i-larva ifakwe kwi-substrate futhi iguqulelwe ibe yi-polyp.

Njenge-polyp lezi zinsuku zempilo yasolwandle ziyancipha ngokufufusa, ukwakha i-polyps indodakazi. Entwasahlobo, i-polyp iphenduka i-larva-ether, futhi i-ether kancane kancane iguqula ibe i-jellyfish.
