Izici nendawo okuhlala kuyo isicabucabu
Isiphambano isiphambano kungokomndeni we-orb-web. Isicabucabu saqanjwa ngegama elingajwayelekile kangako ngenxa yesiphambano esikhulu esibonakalayo ngemuva, esakhiwe ngamabala akhanyayo.
Isisu se- "flycatcher" sinesimo esiyindilinga esifanele, imvamisa sinsundu, kodwa kukhona futhi isiphambano esimhlophe, isisu sayo siphuzi ngokukhanyayo noma i-beige ngombala. Imilenze emide izwela kakhulu ekudlidlizeni okuncane kwewebhu.
Ngabe isicabucabu spider ngazimbili ngamehlo, ibekiwe ukuze isinambuzane sibe nokubuka okungama-360-degree. Kodwa-ke, umbono wakhe ushiya ongathandeki, isicabucabu singabona kuphela izithunzi nezinhlaka zezinto ezingekho.
Izinhlobo zeziphambano zesicabucabu okuningi - cishe ngo-2000, eRussia nase-CIS kukhona abangu-30 kuphela, futhi bonke bangaziqhayisa ngesiphambano esiveziwe esiswini esingaphezulu.
Esithombeni kukhona isicabucabu esimhlophe
Ubukhulu besifazane bungahluka kusuka kumasentimitha angu-1.5 kuye ku-4 (kuya ngokuthi ungowenhlobo ethile), owesilisa - kuze kufike kusentimitha elilodwa. Okumangalisa futhi ukuthi ingxube exubile yomzimba wesinambuzane - i-mixocel, evele ngenxa yokuxhuma komgodi oyinhloko kanye nowesibili.
Enye yezinhlobo ezivame kakhulu isiphambano esijwayelekile. Insikazi yalezi zinhlobo ingafinyelela kumasentimitha angu-2,5 ubude, abesilisa bancane kakhulu - kuze kufike kusentimitha elilodwa. Isisu emadodeni sibucayi, kwabesifazane sikhulu futhi siyindingilizi. Umbala ungashintsha kancane, uzivumelanise nokukhanyisa ngesikhathi esithile.
Umzimba wesicabucabu umbozwe ngengcina ekhethekile esiza ukugcina umswakama. Isicabucabu sowesifazane inokuvikelwa okuthembekile - i-cephalothorax, lapho amehlo atholakala khona.
Esithombeni, isicabucabu sesicabucabu sowesifazane
Izindawo zokuhlala ezikhethwayo zihlala zimanzi futhi zinomswakama. Lokhu kungaba ngamahlathi, amasimu kanye nezimfunda eduze kwamaxhaphozi nezindawo zokugcina amanzi, ama-groves, izingadi, futhi kwesinye isikhathi izakhiwo zabantu.
Isimo nendlela yokuphila yesicabucabu sesicabucabu
Imvamisa, isicabucabu sikhetha umqhele wesihlahla endaweni yaphakade yokuphila. Ngakho-ke, ngokushesha uhlela inetha lokubamba (phakathi kwamagatsha) nesiphephelo (emaqabunga aminyene). I-spider spider web ibonakala ngokucacile ngisho nasebangeni elithile, ihlale iyindilinga futhi ilingana futhi inkulu kakhulu.
Isicabucabu sasekhaya siqapha ngokucophelela isimo semicu ekuwebhu futhi uqiniseke ukuthi siyivuselela ngokuphelele njalo ezinsukwini ezimbalwa. Uma iwebhu enkulu iba ugibe lwesinambuzane, isicabucabu "esingahambisani naso," iphula imicu ezungeze isisulu sayo bese iyayisusa.
Ukushintsha isicupho esidala ngesisha kuvame ukwenzeka ebusuku, ukuze kuthi ekuseni kube sekulungele ukuzingela. Lokhu kwabiwa kwesikhathi nakho kufaneleka ngokuthi ebusuku izitha zesicabucabu ziyalala, zingalethi ngozi, angawenza umsebenzi wakhe ngomoya ophansi.
Esithombeni, ubulembu besicabucabu
Kungabonakala sengathi isicabucabu esicishe sibe yimpumputhe singazakha kanjani izakhiwo eziyinkimbinkimbi kangaka ebumnyameni obukhulu! Kodwa-ke, kulokhu, akususelwa ekubukeni, kepha ekuthinteni, yingakho inethiwekhi ihlale ilingana. Ngaphezu kwalokho, insikazi iluka inetha ngokwemigomo eqinile - ibanga elifanayo phakathi kwamaphuzu lihlala ligcinwa kuyo, kunama-radii angama-39, amajika angama-35 nezindawo zokuxhuma eziyi-1245.
Ososayensi bathole ukuthi leli khono lisezingeni lofuzo, isicabucabu akudingeki sifunde lokhu - senza konke ukunyakaza ngokungazi, ngokuzenzekelayo. Lokhu kuchaza ikhono lezicabucabu ezincane zokuluka iwebhu efanayo nabantu abadala.
Imiphumela yokulunywa yisicabucabu kungalindeleka, ngoba ubuthi bayo bunobuthi hhayi kuphela ezinambuzaneni, kodwa nakwizilwane ezinomgogodla. Ukwakheka kobuthi kufaka ne-hemotoxin, enomphumela omubi kuma-erythrocyte ezilwane.
Kumele uqaphele ukuthi izinja, amahhashi nezimvu ziyamelana nazo ukulunywa isicabucabu... Ngenxa yokuthi ubuthi bunobuthi, futhi nalokho ukulunywa isicabucabu futhi angaluma ngisho ngesikhumba somuntu, kukhona umbono wokuthi uyingozi kubantu.
Kepha, konke lokhu kungukubandlulula. Okokuqala, inani lobuthi obukhishwe ngesikhathi esisodwa lincane kakhulu ukulimaza isilwane esincelisayo esikhulu, okuyiyona indoda. Okwesibili, ubuthi busebenza ngokuguquguqukayo kuma-vertebrate. Ngakho-ke kowesilisa isicabucabu sesicabucabu asiyona ingozi (Okuhlukile ngabantu abanokubekezelelana ngakunye).
Ukudla kwesicabucabu
Ukudla okuyinhloko kweziphambano kuqukethe izimpukane ezahlukahlukene, omiyane nezinye izinambuzane ezincane, ezingadla cishe eziyishumi nambili ngasikhathi. Into enamathelayo iqale ikhishwe esihlahleni sesicabucabu, esiba yintambo eqinile emoyeni kuphela.
Enetheni elilodwa lokudoba, isiphambano singakhiqiza futhi sisebenzise cishe amamitha angama-20 kasilika. Ukuhamba kuwebhu, umnikazi wayo uthinta kuphela imicu ye-radial, enganamatheli, ngakho-ke yena akanamatheli.
Ngesikhathi sokuzingela, isicabucabu silinda maphakathi nesihibe noma sihlale entanjeni yesiginali. Lapho isisulu sinamathela enetheni futhi sizama ukuphuma, iwebhu iqala ukudlidliza, umzingeli uzwa ngisho nokudlidlizela okuncane ngezitho zakhe ezibucayi.
Isicabucabu sijova umthamo wobuhlungu esilwaneni futhi, ngokuya ngesimo, singasidla ngokushesha noma sishiyele kamuva. Uma lesi sinambuzane sisebenza njengomthombo oyinqolobane wokudla, isicabucabu siyasimboza ngezicubu bese sikufihla ngokuphepha endaweni yaso yokukhosela.
Uma isinambuzane esikhulu kakhulu noma esinoshevu sibanjwa ogibeni, isicabucabu siqhekeza iwebhu siyisuse. Isicabucabu sigwema ukuxhumana nezinambuzane ezibeka amaqanda kwezinye izinambuzane noma izilwane, ngoba isisu esikhulu sesicabucabu singaba yindawo enhle yezibungu.
Inqubo yokugaywa kwesicabucabu yenzeka emzimbeni wesisulu ngosizo lwamajusi okugaya. Isicabucabu uqobo, njengezinye izicabucabu, asikwazi ukugaya ukudla.
Ukuzala kanye nesikhathi sokuphila sesicabucabu sesicabucabu
Isicabucabu owesilisa encane, i-nondescript futhi imvamisa ifa ngemuva kokukhwelana kwayo kokuqala. Yingakho ke esithombeni owesifazane uvame ukushaya uqweqwe - inkulu futhi yinhle.
Isicabucabu siqala ukufuna umngane ekwindla. Ihlala onqenqemeni lwewebhu yayo futhi idale ukudlidliza okuncane. Insikazi iyasibona isignali (ayiyithathi njengempango) bese isondela kwisicabucabu.
Ngemuva kokukhwelana, insikazi ilungiselela ukubeka, iluke umfece onamandla onokwethenjelwa, lapho izobeka khona wonke amaqanda ekwindla. Khona-ke umama ufihle ngokuthembekile umfece, amaqanda acwilise endaweni akhethwe nguye, futhi kuvele kuphela izicabucabu zasentwasahlobo.
Zonke ihlobo ziyakhula, zihamba ngezinqubo eziningana ze-molting futhi zikulungele ukuzala kuphela ekwindla elandelayo. Owesifazane uvame ukuhlala kuze kube manje.
Esithombeni kukhona umfece wesicabucabu
Esiphambanweni esivamile, isikhathi sokuzalisa siqala ngaphambi kwesikhathi - ngo-Agasti. Eyeduna futhi iyazifunela umlingani, inamathisela intambo yesiginali kuwebhu yayo, iyidonse, yakhe ukudlidlizela okuthile lapho owesifazane emazi khona.
Uma isilungele inqubo yokukhwelana, ishiya ikhaya layo enkabeni yesihibe bese yehlela kowesilisa. Ngemuva kwemizuzwana embalwa, isenzo sesiphelile, noma kunjalo, kwezinye izimo kungaphindwa. Ekwindla, insikazi yenza i-clutch ku-cocoon iyifihle, bese iyafa. Ngemuva kokubhala ngaphezulu, izicabucabu zizalwa entwasahlobo. Ehlobo bayakhula futhi babe nesikhathi sasebusika esisodwa.
Kuphela ngehlobo elilandelayo baba ngabantu abadala futhi bakulungele ukuzala. Kungakho impendulo engaqondakali embuzweni othi “isicabucabu siwela isikhathi esingakanani»Cha - konke kuncike ekutheni umuntu othile unhloboni yohlobo oluthile.
