Isicabucabu sabadobi (i-Dolomedes triton) singesama-arachnids ekilasi.
Ukusabalala Kwesicabucabu
Isicabucabu sabadobi sisatshalaliswa kakhulu kulo lonke elaseNyakatho Melika, esingatholakali kakhulu ePacific Northwest. Itholakala e-East Texas, ezifundeni ezisogwini lwaseNew England naseningizimu ngasogwini lwe-Atlantic kuya eFlorida nasentshonalanga kuya eNyakatho Dakota naseTexas. Lesi sigcawu singatholakala futhi ezindaweni ezinomswakama zaseMelika Ephakathi kanye naseNingizimu Melika.
Isicabucabu - indawo yabadobi
Isicabucabu sabadobi sihlala otshanini obuzungeze amachibi, imifula, amachibi, izikhumulo zemikhumbi nezinye izakhiwo eziseduze kwamanzi. Kwesinye isikhathi kutholakala entanta ebusweni bechibi ezindaweni zasemadolobheni.
Izimpawu zangaphandle zesicabucabu - umdobi
Isicabucabu somdobi sinamehlo ayisishiyagalombili, ahlelwe ngemigqa emi-2 evundlile. I-cephalothorax nesisu kucishe kube ngosayizi ofanayo. Isisu siyindilinga ngaphambili, sibanzi phakathi futhi sithinta ngasemuva. Isisekelo sesisu sinombala onsundu onsundu noma ophuzi ngokunsundu ngemiphetho emhlophe kanye namachashazi amhlophe maphakathi. I-cephalothorax nayo imnyama nsundu ngomugqa omhlophe (noma ophuzi) eceleni komjikelezo wohlangothi ngalunye. Ingxenye engezansi ye-cephalothorax inezindawo eziningi ezimnyama. Ubukhulu besifazane bungu-17-30 mm, abesilisa bangu-9-13 mm.
Izicabucabu ezindala zinemilenze emide kakhulu, ehlukanisiwe. Okukhulu kunombala onsundu ngombala, ngezinwele ezimhlophe ezigqamile noma ngezinsipho eziningi eziminyene, ezimnyama. Kunezinzipho ezi-3 kuzona kanye izeluleko zezinyawo.
Ukuzalisa isicabucabu - umdobi
Ngesikhathi sokuzala, isicabucabu somdobi sithola insikazi ngosizo lwama-pheromones (izinto ezinukayo). Ngemuva kwalokho wenza "umdanso" lapho eshaya khona isisu sakhe ebusweni bamanzi bese evayizisa izingalo zakhe zangaphambili. Ngemuva kokukhwelana, insikazi ivame ukudla eyeduna. Ubeka amaqanda ngobukhulu besicabucabu se-spider web cocoon esingu-0.8-1.0 cm.Okokusebenza komlomo uyigcina cishe amasonto ama-3, ayivimbele ukoma, ayicwilise emanzini njalo futhi azungezise izitho zayo zangemuva ukuze ukhokho uswakanyiswe ngokulinganayo.
Ekuseni nakusihlwa, ikhipha ukhokho elangeni.
Ube esethola uhlaza oluminyene olufanele olunamahlamvu amaningi, bese ulenga umfece kuwebhu, kwesinye isikhathi ngaphezu kwamanzi.
Abesifazane bagada isikhwama esisilika kuze kuvele izicabucabu. Izicabucabu ezincane zihlala endaweni ethile elinye isonto ngaphambi kwe-molt yokuqala, bese zijika noma zindize ngaphezu kwamanzi ngentambo yobulembu zifuna ichibi elisha. Ngemuva kobusika, izicabucabu ezincane ziyazala.
Ukuziphatha kwabadobi besicabucabu
Isicabucabu umdobi yedwa ozingela emini noma othanda ukuhlala acashele amahora amaningana. Usebenzisa amehlo akhe amahle kakhulu ukubamba inyamazane lapho etshuza. Eduze kwamanzi, ihlala endaweni enelanga ezihlahleni zemihlanga noma emaceleni.
Isicabucabu sabadobi kwesinye isikhathi sakha amagagasi ebusweni bamanzi ngemilenze yaso yangaphambilini ukuze sidonse izinhlanzi. Yize ukuzingela okunjalo kungaphumeleli kakhulu futhi kuletha isisulu emizameni engu-9 kwengu-100. Ihamba kalula emanzini, isebenzisa ukumanzana okuphezulu kwamanzi nezinwele ezinsundu ezicutshini zemilenze yayo, zimbozwe ngento enamafutha. Akunakwenzeka ukugijima ngokushesha ebusweni bamanzi, ngakho-ke isicabucabu somdobi siyashibilika eceleni kongqimba lwamanzi, njengakwi-skis. Imigodi yamanzi eminyene yakha ngaphansi kwezinyawo, lapho ifilimu lamanzi lokungezwani komhlaba kwezigi zamanzi.
Kwezinye izimo, isicabucabu somdobi sihamba ngokushesha okukhulu ukuze singaphuthelwa isinambuzane esiwele emanzini.
Kepha ngokushibilika ngokushesha, ingcindezi yezitho emanzini iyanda, futhi isicabucabu singacasha emanzini. Esimweni esinjalo, uyancika emuva, uphakamisa umzimba wakhe emilenzeni yakhe yangemuva bese egijima ngokushesha emanzini ngesivinini samamitha angu-0.5 ngomzuzwana. Isicabucabu - umdobi onomoya omuhle okhukhulayo, esebenzisa izindwani zotshani noma amaqabunga, njengesihlenga. Kwesinye isikhathi umane aphakamise izitho zangaphambili futhi angene emanzini, kube sengathi useyili. Izicabucabu ezisencane ziphumelela ngokukhethekile ukundiza phezu kwamanzi. Ngakho-ke, izicabucabu zihlala ezindaweni ezintsha.
Uma kunengozi, isicabucabu - umdobi uyacwila futhi alinde usongo ngaphansi kwamanzi. Emanzini, umzimba wesicabucabu somdobi umbozwe amagwebu amaningi omoya, ngakho-ke noma echibini, umzimba wakhe uhlala womile futhi awumanzi. Lapho uhamba emanzini, umbhangqwana wesibili nowesithathu wemilenze egobile kancane usebenza. Isicabucabu sihamba emhlabeni, njengamanye ama-arachnids.
Ebangeni elingamamitha ama-3-5, angabona ukusondela kwesitha, acwile ngaphansi kwamanzi bese efihla, ebambelela ngeziqu zezitshalo zasemanzini. Isicabucabu singahlala ngaphansi kwamanzi kuze kube yimizuzu engama-45, sisebenzisa umoya emabhamuzini abhajwe yizinwele emzimbeni ngokuphefumula. Ngosizo lwawo la magwebu omoya, isicabucabu somdobi sintanta ngaphezulu echibini.
Izicabucabu ezisencane zilala ezinqwabeni zemfucumfucu yezitshalo namaqabunga awile eduze kwezidumbu zamanzi. Kunobufakazi bokuthi lezi zigcawu zabadobi zinganamathela utshani futhi zishiye ngentambo yesicabucabu futhi, kule moto entantayo, zihanjiswe ngumoya ovunguzayo onqamula echibini. Ngakho-ke, lesi spider akuyona nje umdobi kuphela, kepha futhi siyi-raftsman. Ukulunywa kubuhlungu, ngakho-ke akufanele umcasule futhi umbambe ngesandla sakho.
Ukudla kwesicabucabu - umdobi
Isicabucabu sabadobi sisebenzisa amagagasi agxilile ebusweni bamanzi ukufuna inyamazane ukuthola indawo ngqo yesisulu ebangeni elifinyelela ku-18 cm kuya phambili. Uyakwazi ukungena ngaphansi kwamanzi ngokujula okungama-20 cm ukuze abambe inyamazane. Isicabucabu - umdobi uzondla ngezibungu zemicibisholo yamanzi, omiyane, ojekamanzi, izimpukane, onoshobishobi nezinhlanzi ezincane. Ukubamba inyamazane, kuluma, bese kugwini, kukhipha kancane kancane okuqukethwe yisisulu.
Ngaphansi kwethonya lejusi lokugaya, hhayi kuphela izitho zangaphakathi ezigaywayo, kepha futhi nesembozo esiqinile sesinambuzane. Udla ukudla okuphindwe kahlanu kwesisindo sakhe ngosuku olulodwa. Lesi silwane sicasha ngaphansi kwamanzi lapho sibalekela izilwane ezizingelayo.
Incazelo yesicabucabu umdobi
Isicabucabu sabadobi, njengazo zonke izinhlobo zesicabucabu, siyisilawuli sezinambuzane. Lolu hlobo aluningi kangako, kanti kwezinye izindawo ama-dolomedes ayisicabucabu esingajwayelekile futhi afakwa kwiRed Data Books yesifunda. Uhlu Olubomvu lwe-IUCN alunaso isimo esikhethekile.
