Izici nendawo okuhlala kuyo isihlukanisi samanzi
Umgibeli wamanzi yisinambuzane esikwazi ukuhamba phezu kwamanzi. Akunzima ukubona izidalwa ezithakazelisa kangaka ezilwaneni zasendle, ziphumula ehlobo ogwini lwedamu elithile elizolile.
Umgibeli wamanzi inesimo esihlanganisiwe, futhi ngokubukeka kufana nezikebhe ezincane, ezihamba ngokushesha ebusweni bamanzi. Umgibeli wamanzi (isigaba izinambuzane) ungumnikazi wemilenze emide ezacile, ngosizo lwayo angahamba kalula ebusweni bamachibi, afana ne-virtuoso skater, obuciko nobuchule bayo babunakekelwa ngokwemvelo uqobo.
Umzimba wezidalwa ezinjalo, njengoba ubona ku isithombe sabahluzi bamanzi, ngaphandle ifana nenduku encane. Izisu zazo zimbozwe ngokuphelele ngezinwele ezimhlophe, ezinikezwa into ekhethekile ye-waxy, ngakho-ke umzimba omncane wesidalwa nemilenze yaso awumanzi lapho uhamba emanzini.
Ngaphezu kwalokho, kwakhiwa amabhamuza womoya phakathi kwezinwele ezincane kakhulu, ezivumela izinambuzane ukuthi zingacwilisi emanzini, yize isisindo sazo esincane sinegalelo kulokhu. Le yiyo yonke incazelo ye- kungani umgibeli wamanzi engashoni.
Esithombeni, i-bug is a strider water
Isakhiwo semilenze sisiza nalezi zidalwa ukuba zihambe ngobuciko. Yize zizacile, zikhuluphele kakhulu ezindaweni zokunamathiselwa emzimbeni futhi zihlonyiswe ngemisipha enamandla kakhulu esiza ukukhulisa okukhulu, uma kuqhathaniswa nosayizi walezi zidalwa, isivinini.
Incazelo yomgibeli wamanzi kungaqhubeka ngokusho ukuthi cishe izinhlobo ezingamakhulu ayisikhombisa zezidalwa ezincane ezinjalo zihlala emvelweni. Ngokuqondene nokuhleleka kwezimbungulu, ama-striders amanzi ayisihlobo esiseduze kakhulu salezi zinambuzane.
Phakathi kwezinhlobo ezaziwayo kukhona i-water strider enkulu, umzimba wayo ofinyelela kubude obungamasentimitha ama-2. Inamaphiko nombala obomvu womzimba. Isihambisi samanzi echibi asikho ngaphezu kwesentimitha ngosayizi, sinombala onsundu onsundu futhi sinemilenze elula. Abesilisa nabesifazane balezi zinhlobo zezinambuzane bangahlukaniswa kalula ngombala wesisu, ngoba okokuqala kumnyama, kanti kwesibili kubomvu.
Isici sempilo yesikebhe samanzi yikhono lokugxila emgodini onolaka oluyingozi wamachibi amakhulu kasawoti. Izidalwa ezinjalo zibandakanya umgibeli wamanzi olwandle. Usayizi wayo mncane kakhulu uma uqhathaniswa nama-congener awo amanzi angenasawoti.
Ubude balesi sidalwa bufinyelela ku-5mm kuphela. Lezi zidalwa ezinesibindi, ezijwayele ukulwa nomgodi onganamkhawulo wolwandle, ziyakwazi ukwenza ijubane elihlaba umxhwele lezidalwa ezincane kakhulu, ezicishe zifane namandla omuntu okuhamba emhlabeni. Izinambuzane ezinjalo zihlala olwandle lwaseNdiya nolwePacific. Bangabonakala ngisho nakubanga lamakhilomitha ambalwa ukusuka ogwini.
Isimo kanye nendlela yokuphila yomgibeli wamanzi
Kungani umgibeli wamanzi aqanjwa kanjalo? Igama lesinambuzane lidlulisa ngokunembile indlela yaso yokuphila, ngoba sonke isikhathi esabelwe ukuba khona, lesi silwane senza ukukala ingaphezulu lamanzi ngemilenze yaso emide emangalisayo, okuhlangene indawo yokuhlala isihambisi samanzi.
Lezi zinambuzane zinamabhangqa amathathu emilenze, ahlukene ngosayizi. Imilenze yabo yangaphambili imfishane kunaleyo yonke futhi iyasetshenziswa, phakathi kwezinye izinto, njengohlobo lwesondo lokushayela, okusho ukulawula inkomba nokushesha kokunyakaza.
Ngosizo lwamanye amabhangqa amabili umgibeli wamanzi—isinambuzane ushelela emanzini, njengomgwedli esikebheni, esebenza ngezidladla zakhe. Ngaphezu kwalokho, lesi sidalwa esiphilayo sinezimpondo ezisekhanda laso, ezikwazi ukubamba ngisho nokudlidlizela okungabonakali kakhulu kwemvelo yasemanzini, kusebenza njengohlobo lomamukeli wolwazi oludingekayo oluvela emhlabeni wangaphandle njengomuzwa wokuthinta nephunga.
Izinambuzane zinombala onsundu onsundu, onsundu, kwesinye isikhathi uze ucishe ube mnyama, okuzobanikeza ukuvikeleka okuhle, kuzenze zingabonakali ezitheni, ikakhulukazi izinyoni ezidla inyama, ezingaba yizisulu zazo.
Ukuba ngumhlali hhayi nje kuphela wamachibi namachibi athule, kepha futhi namachibi amancane, umgibeli wamanzi uyakwazi ukundiza esuka ezindaweni ezomile zemizimba yamanzi engajulile ngosizo lwamaphiko ane-webbed afihlwe ngaphansi kwe-elytra. Kuyiqiniso, lezi zinambuzane azijwayeleki kakhulu ezindizeni, okwenza ukunyakaza komoya kungavamile kakhulu futhi kuphela uma kudingeka.
Uma usendleleni izihlungi zamanzi kuvela izithiyo ezingalindelekile, okungaba yizitshalo zasemanzini noma amagagasi amancane endaweni ethulile yamanzi, uyakwazi ukugxuma okuxakile, acindezele izidladla zakhe emanzini, ngaleyo ndlela anqobe isithiyo esiphazamisa ukuqhubeka kwakhe. Ukugxuma okuchaziwe kumsiza ekwenzeni imilenze yangemuva emide.
Njengokuntanta amabhungane, umgibeli wamanzi isebenzisa izidladla zayo njengohlobo lwephedi. Kepha ngokungafani nezihlobo zezinambuzane ezibalwe ngenhla, ayilungiselwanga ukutshuza.
Esithombeni, umgibeli wamanzi omfula
Ukugwedla emanzini ngezitho zayo, kwakha ama-swirls amanzi asiza ukuhamba kwawo kuphela futhi akwenze ukuthi kungahambi nje kuphela emanzini apholile, kepha futhi nasemagagasini olwandle. Usebenzisa imilenze yakhe emide njengezigwedlo, eyendlala kabanzi futhi ngobuciko ehambisa isisindo sakhe somzimba endaweni enkulu ukunciphisa ingcindezi emanzini.
Njengabagijimi abahle kakhulu emanzini, ama-striders wamanzi awashintshelwa nakancane ukunyakaza okuphawulekayo emhlabeni, abawathatha kuphela lapho kunesidingo sokuxazulula "amafulethi" asebusika.
Ekufuneni kwabo okuphikelelayo ukuthola indawo ephephile, bahla enyuka bewela phansi. Indawo yabo yokuhlala emakhazeni ingaba yizinhlobonhlobo zemifantu ezihlahleni nasemagxolo abo, kanye nezitshalo ezifanele, isibonelo, ubulembu.
Umsoco we-strider yamanzi
Kuyamangaza ukuthi isidalwa esincane, esibonakala singenacala - umgibeli wamanzi ezinambuzane, uyisidli sangempela. Lezi zidalwa azidli nje kuphela izihlobo zesigaba sazo, kepha ziphazamisa nezilwane ezinesisindo, zondla, ngokwesibonelo, abamele abancane bezilwane, abakwaziyo ukuzitholela ezizindeni zabo zamanzi.
Bayakwazi ukubona inyamazane yabo ngosizo lwezitho zombono eziyindilinga, okungukuthi, amehlo abanawo. Izingalo zawo zangaphambili zifakwe izingwegwe ezikhethekile, abazisebenzisela ukubamba izisulu zabo.
Phakathi kwezinye izinto, lesi sihambisi samanzi sine-proboscis ebukhali, eqala ukusebenza, ifake futhi imunce okuqukethwe okuyigugu. Lapho esesuthi, ugoqa ucingo lwakhe ngobumbano, alugobise ngaphansi kwesifuba sakhe, ngakho-ke i-proboscis ayiphazamisi ukuhamba kwabagibeli bamanzi nempilo yabo ejwayelekile.
Umgibeli wamanzi olwandle uzondla nge-fish caviar, i-physalis ne-jellyfish. Imvelo futhi idale izinhlobo zezinambuzane zemicibisholo yamanzi, izibungu zamanzi eziphila ngokumunca igazi lezinambuzane ezahlukahlukene.
Phakathi kwabahluli bamanzi, izimpi azivamile phakathi kwabo ngenxa yemidanso abafuna ukuyibamba ngezidladla zangaphambili. Basebenzisa lezi zitho ezifanayo, bangena emzabalazweni nezihlobo zabo eziyizimbangi futhi bathatha inyamazane yabo kubo.
Izinambuzane ezibuthakathaka, ezingakwazi ukunamathela, zibambelele, zisuse amanani azo, zilahlekelwe ukuqina kwemilenze yazo yangaphambili, zivame ukuwa futhi zindiza ikhanda phezu kwezithende ngendlela engaziwa. Futhi izimbangi ezinobuqili nezinobuqili ziyaphumelela, ziphunyuke ngobumnandi ziye endaweni ecashile ukuze zijabulele ngasese inyamazane enqotshiwe.
Ukuzaliswa kanye nesikhathi sokuphila somgibeli wamanzi
Umgibeli wamanzi ubeka amaqanda akhe emaqabungeni emanzini ezitshalo, awahlanganise ngofinyela olukhethekile. Ukwakheka okunjalo ohlangothini kufana nentambo ende efana nejeli, okuyidiphozi yamashumi amasende ambalwa.
Kwesinye isikhathi imigoqo yenziwa emugqeni owodwa ohambisanayo ngaphandle kokusebenzisa into enomunyu, ngenkathi kwakhiwa uchungechunge lwamasende ezinambuzane. Ukuhlangana kwezinhlobo ezincane zalezi zidalwa kuyehluka ngokuthi amasende avele anamathele ezicutshini ezithambile zezitshalo.
Abesilisa babamba iqhaza kuyo yonke imicimbi kuze kufike ekutheni bahamba "nezintombi" zabo ngesikhathi sokubeka imvuthu, babavikela ezingozini nasekubavikeleni. Ngenkathi yokukhwelana, obaba bamanzi-obaba baqapha indawo yabo ngokuqina komona, becindezela ngendlela enqumayo kakhulu konke ukuthambekela kwezimbangi. Yile ndlela lezi zinambuzane ezizala ngayo.
Inqubo yokwenziwa kabusha kohlobo lwayo yenziwa ngokungakhathali ngabagibeli bamanzi abavuthiwe ngokocansi zonke izinsuku zasehlobo. Futhi izibungu ezivela emasontweni ambalwa, zidlula kuzo zonke izigaba zokukhula esikhathini esingangenyanga, futhi ngokushesha ziphenduke zibe ngabantu abadala.
Izilwane ezincane zingahlukaniswa nabazali bazo ngosayizi womzimba kuphela nangokubonakala kwesisu esifushane, esivuvukile. Izikebhe zamanzi zihlala cishe unyaka. Futhi inani lalezi zinhlobo zezinambuzane alisongelwa nganoma iyiphi ingozi, ngoba lezi zidalwa ezikhethekile zifanelana ngokuqinile nomfanekiso jikelele wezilwane.
