I-Las i-sea jellyfish Zingezinye zezilwane zasendulo ezikhona. Bebesemhlabeni iminyaka engaphezu kwezigidi ezingama-600 futhi bahlukaniswa yisayensi njengezilwane zasendulo eziyinkimbinkimbi kunazo zonke ezikhona. Kunzima ukucabanga ukuthi lezi zilwane zingadlani i-priori, ngoba iningi lomzimba wazo linamanzi.
Kulesi sihloko sizokwazi ngokujula i-jellyfish yasolwandle kanye nemininingwane eminingi ezokuhlaba umxhwele ngokwanele ukwazi. Ngabe ufuna ukuthola umhlaba othakazelisayo walezi zilwane zasendulo? Qhubeka ufunde ukuze ufunde kabanzi.
Yini i-sea jellyfish
Into yokuqala okufanele siyichaze ukuthi iyini i-jellyfish yasolwandle. I-invertebrate eyaziwa ngokuthi i-aguaviva, ngoba ukwakheka kwayo kakhulu kungamanzi. Kunjengokungathi amanzi athatha ukuphila ukuze akhe lezi zinto eziphilayo. Abanalo noma yiluphi uhlobo lwama-exoskeleton ukuze bazivikele ezilwaneni ezidla ezinye, njengoba kunjalo nangezinye izilwane zasolwandle, kepha sebenzisa ubuthi babo njengokuvikela nokuhlasela.
Indawo abahlala kuyo ingeyokwandiswa konke kwezilwandle nezilwandle, njengoba bekwazile ukujwayela, kukho konke ukuguquka, kuzo zonke izinhlobo zezimo nezimo zasolwandle. Esinye sezizathu kwesinye isikhathi sithola i-jellyfish eduzane nolwandle kungenxa yokuthi kufanele basondele kancane ukuze baqale umjikelezo wabo wokuzala.
Iningi lalezi zinto eziphilayo zihlala endaweni ye-pelagic (Bheka izilwane zasolwandle ze-pelagic ne-benthic). Leli zinga libanzi kakhulu kulo lonke ulwandle futhi yilona elingaphansi noma ngaphansi kwamamitha angama-200 ukujula.
Incazelo ejwayelekile
I-Jellyfish ine-morphology encike ngokuphelele ezinhlotsheni esizelaphayo. Kungaba nezinhlobo ezahlukahlukene ezinokuziphatha okungafani ngaphansi kwamanzi. Iphuzu elijwayelekile lapho yonke i-jellyfish inayo ukuma kwensimbi yayo ngokuthungwa okungenakuphikwa kwe-gelatinous. Eziningi zalezi zinhlobo ziyakhanya ngombala ukuze ukwazi ukubona ingaphakathi lesilwane ngaphandle kokuvula.
Ukutadisha i-jellyfish kuyamangaza ngoba, kokujwayelekile, lapho ingaphakathi layo lihlaziywa kungabonwa ukuthi alinazo izitho ezingabalulekile kithina. Ngokwesibonelo, lezi zilwane azinayo inhliziyo, ubuchopho noma amaphaphu. Yize ukuvela kwe-jellyfish kungakahambi kakhulu, ukukhula kwayo nokuba yinkimbinkimbi kwayo kuyivumele ukuthi iqhubeke iphila futhi isabalale izinkulungwane zeminyaka.
Yize ingenazo izitho ezingenakufakwa endaweni yethu, iyisidalwa esinamandla futhi esinamandla esesatshwa abanye abaningi. Lapho ezinye izilwane zasolwandle zahlulela i-jellyfish ngokubukeka kwazo, zingaba sengozini enkulu phambi kwazo. Futhi ukuthi lezi zilwane zinobuthi obubulalayo ezinhlotsheni eziningi. Ukuphela kwento engabonwa uma sihlaziya ingaphakathi le-jellyfish isisu. Yilokho okudingayo ukuze ukwazi ukugaya konke ukudla okudlayo ukukuguqula kube izakhamzimba.
Ubuthi beJellyfish bungaba yingozi kangako uyakwazi ukubulala umuntu ngemizuzu nje embalwa. Ngokuya ngezinhlobo esibhekene nazo kanye nendlela esiya ngayo kwezokwelashwa, impilo ingasindiswa noma ingalondolozwa.
Ubuthi obuyisici
Esinye sezici eziyinhloko i-sea jellyfish enaso ubuthi babo. Kuyinto enobuthi enamandla kakhulu enamaseli ahlabayo abizwa ngama-cnidocyte. Lawa maseli yiwona enza zonke izinhlobo zezinhlobo ze-Cnidarians phylum. Ubuthi uyisebenzisela ukubamba isisulu sakhe futhi ngesisu esingabonakala ngeso lenyama, siyasigwinya bese siguqula sibe izakhi zomzimba.
Isenzo esiyinhloko salolu shevu olubulalayo ukukhubaza isisulu ukuze sikwazi ukusidla. Ukukhubaza ngokuphelele umuntu, ukuminyana kobuthi obufaka emzimbeni wethu kufanele kube ngaphezulu kakhulu kwesilwane sasolwandle. Usayizi wethu nendawo engaphezulu kukhulu kunenhlanzi, ngakho-ke uzodinga ukuphinda kathathu noma ngaphezulu inani lobuthi obusebenzisayo ukushiya umuntu ekhubazeke ngokuphelele.
Kodwa-ke, kunezingozi eziningi esibhekana nazo lapho i-sea jellyfish ibhukuda eduze nogu esikhathini sabo sokuzala. Njalo ngonyaka abantu babulawa yizintambo ze-jellyfish kanti izinkulungwane zabanye ziyalimala futhi bane-isifuba. Kukhona ama-jellyfish ambalwa angasibulala ngokuphelele, kepha kuyadingeka ukuvimbela zonke izimo ezingaba khona.
Impilo nomjikelezo wokuzala
Izinhlobo eziningi ze-jellyfish zinomjikelezo wokuphila ongajwayelekile. Basebenzisa indlela yezocansi eyehluke kancane kuleyo esijwayele ukuyibona. Ukuhlanganisa ama-gametes amabili (owesilisa nowesifazane) yindlela entsha yokuphila ebizwa nge-polyp eyakhiwe ngayo. Le polyp ihlala inamathele ku-substrate yaphansi yolwandle futhi iqala ize iqede umjikelezo wayo futhi kukhulisa ezinye izinkukhu eziningi ze-jellyfish.
Okungukuthi, kusukela esiphambanweni esisodwa phakathi kwe-jellyfish, bangakwazi ukuzala futhi banikeze amakhulu abo. Lesi ngesinye sezizathu esenza ukuthi, ngaphandle kobudlova bayo lapho ihlasela isisulu sayo ngoshevu obulalayo, ikwazi ukusinda futhi iqhubeke nokuba ngolunye lwezinhlobo ezikhona emhlabeni wonke isikhathi esingaphezu kwama-600 namuhla. Izigidi zeminyaka.
Kuyamangaza ukwazi ukuthi lezi zilwane Zisetshenziswa embonini yezemithi futhi yobuhle futhi singakuthola kumikhiqizo eminingi esetshenziswa nsuku zonke.
Njengokujwayelekile kuzo zonke lezi zingqikithi zezilwane ezimangazayo, umuntu onobuchwepheshe bakhe uyakwazi "ukubusa" nokusizakala ngomzimba wakhe ukuze kuzuze yena. Kodwa-ke, kufanele uqaphele kakhulu lapho kukhona ifulegi eliluhlaza olwandle. Lokhu kusho ukuthi ukuminyana kwe-jellyfish eduze nogu kuphakeme nokuthi kufanele uqaphele futhi ungagezi. Ngale ndlela amashwa amaningi azogwenywa.
